Chapter 1109 Industrial Foundation
"But I haven't finished the wine yet. I've only drunk half of it." Hao Pingchuan didn't want to leave at all.

Zheng Chaoyang pulled Hao Pingchuan and said:
"Put the lid on the bottle. The alcohol won't escape. Let's drink it at night. Let's finish our patrol mission first!"

Lao Luo and Zheng Chaoyang looked at each other and carried Hao Pingchuan away.

Even if Lin Hao was a fool, he knew what Lao Luo meant. Didn’t he just want to give the two of them a chance to talk alone?
"Well?" Lin Hao said awkwardly: "How about we just leave it at that for today!"

"Drink!" Bai Ling clinked the bottle with Lin Hao's and then gulped down half the bottle in one breath.

"Don't drink so quickly, it's easy to get drunk!" Lin Hao saw Bai Ling choking and coughing a little, so he quickly patted her back gently.

After a while, I finally calmed down.

Then Bai Ling looked up at Lin Hao, then pounced on him, hugged him and started biting him.

"Woo woo woo~!" Lin Hao was stunned. This woman had no martial ethics at all and actually launched a sneak attack.

In this case, we must fight back.

No, if I resist, wouldn’t that be going against the woman’s will?
But this is not my room after all, and Lao Luo and Zheng Chaoyang might come back suddenly.

"Don't~!"

"This isn't the right place~!"

"I really should go back!"

"Be careful that Lao Luo and the others come back!"

After a long time, Bai Ling was finally convinced, and then Lin Hao got up and left.

"Let me take you there!" Bai Ling said, and sent Lin Hao back to the room!

······
In the early morning, when the sky was slightly bright, Lin Hao's room finally became completely quiet.

Looking at Bai Ling who was exhausted and sleeping soundly, Lin Hao covered her with a thin quilt.

Then Lin Hao got up and left. He still had many important things waiting for him to do.

After arriving at the holy land, Lin Hao brought guards and technical personnel who rushed over from Yangquan and Guxian overnight to Nanping.

This is the Pingshan iron ore-rich area, which is located on the Nilihe-Sanjiaqing iron ore belt. The ore veins are northeast-southwest oriented, and the exposed length of the ore belt is about 10 kilometers.

The exposed thickness is 20-40 meters, with good continuity, stable internal extension, and a high ore grade of 40%. The total reserves are estimated to be more than 4000 million tons.

What is even more rare is that this mineral belt is mainly composed of vanadium-titanium magnetite, which is the best mineral material for refining alloy steel and special steel.

This is the iron mine location closest to the holy land that Lin Hao found from his memory.

Afterwards, Lin Hao brought people and transported the blast furnaces they brought here. These were blast furnaces dismantled from Xiao Rizi.

Although it is second-hand, it is countless times more advanced than those small blast furnaces. In addition to installing the blast furnace equipment, various supporting equipment also need to be installed and prepared.

Ironmaking does not mean simply putting iron ore in a blast furnace and lighting a fire, although that is indeed the procedure.

But before that, there is actually a lot of preparatory work to be done, such as the crushing and screening of iron ore.

Crushing iron ore into a particle size suitable for use in blast furnaces, typically 10-30 mm.

Fine-grained iron ore is mixed with fuel (such as coke powder) and flux (such as limestone) and sintered to make sintered ore through the sintering process to improve the strength and permeability of the ore.

The fine-grained iron ore is also made into pellets and its strength and reducibility are improved by roasting.

There is also coke, which requires heating coal in an air-tight environment to cause it to undergo dry distillation to produce coke.

Coke is the main fuel for blast furnace ironmaking and also plays a role in supporting the charge.

Coke also needs to be crushed and screened. Coke needs to be crushed into a particle size suitable for use in blast furnaces, usually 10-30 mm.

Limestone flux is also needed to adjust the chemical composition of the slag and improve the fluidity of the slag. Dolomite is also used as a flux to adjust the chemical properties of the slag.

At this stage, it is also necessary to mix the iron ore, coke and flux in a certain proportion according to the composition of the iron ore and the process requirements of the blast furnace.

At this time, it is the blast furnace's turn to come out. According to the loading procedures, the charge is evenly loaded into the blast furnace through the hopper and distributor on the top of the blast furnace.

The next step is the ignition stage. The blast furnace that Lin Hao brought was dismantled from the Yawata Iron and Steel Works. Like the No. 9 blast furnace in Anshan, it has a volume of 900 cubic meters and a designed daily output of 700 tons.

After preliminary preparation work, the foundation pit was excavated and concrete was poured according to the drawings the day before yesterday.

Then came the work of installing blast furnaces and coking equipment, which Lin Hao handed over to technicians transferred from Yangquan and Guxian.

"Technician Wang, the subsequent construction of the blast furnace depends on you!" Lin Hao said with a smile.

Lin Hao has other things to do and it is impossible for him to stay around the blast furnace all the time, so the specific work has to be done by these technical backbones.

"Don't worry, Mr. Lin. We have already built a small blast furnace in Yangquan. The drawings you provided are so detailed that there will be absolutely no problem in building it!" several technicians assured.

"That's good!" Lin Hao nodded in agreement.

In order to complete the installation as soon as possible and put the ironworks into production, Lin Hao plans to use space equipment to secretly help catch up with the progress.

There is no other way. It will take a long time to install it step by step, and Lin Hao can't stay here forever.

During the installation period, Genshan Coal Mine also began to transport coal here with the coal mining equipment brought by Lin Hao.

This local coal mine in Pingshan has small reserves and was closed in the 90s. However, it is still producing coal in a steady stream, so there is no need to worry about coal problems in the short term.

······
Next, Lin Hao took the processing equipment and prepared to upgrade the equipment at the military factory in Pingshan County.

After carefully understanding the production situation, Lin Hao was also shocked.

"I didn't expect Pingshan County's military production capacity to be so strong!" Lin Hao said with emotion to the leader in charge of military industry.

"This is the result of the full support of our people!" said the military industry leader with emotion.

The 33rd Arsenal of the North China Military Region was dispersed throughout Pingshan County. The county was able to produce its own sulfuric acid, smelt copper using traditional methods, and produce explosives.

It can also produce 75mm mountain artillery shells, 60, 82, 130 mortar shells, grenades and bullets.

其中，北冶厂月生产75山炮炮弹1500发，南冶分厂月产82毫米轻重迫击炮弹15000发，唐家会和罗汉坪分厂月产130迫击炮弹5000发。

The Mupan Branch produces 15 grenades and 20 reloaded bullets per month.

They actually managed to achieve such an output by relying on simple machine tools and manual, small-workshop production in each village.

I have to say, this is a miracle, and this is just Pingshan County.

You should know that there are many such arsenals throughout North China and in the Taihang Mountains.

At this time, our party relied on the people to make ammunition by hand, and supported the People's Liberation Army to defeat the Kuomintang. The people worked in the fields during the day, and transported ammunition and supplies to the front line at night under the organization of the militia.

The entire Pingshan County had a total population of only 25, but 7 of them joined the army and fought in the war, 2 of them participated in the Eighth Route Army, and nearly 5000 of them died.

Except for women, the elderly and children, all young and middle-aged people in Pingshan County served in the army.

The rest of the people manufactured weapons and ammunition for the People's Liberation Army, produced food, and transported supplies.

No wonder, when he was discussing whether to build several small blast furnaces for iron smelting or to directly build a large blast furnace, several bigwigs unanimously said to build a large one.

There is no way. The two blast furnaces in Yangquan and Guxian have a combined annual output of only 14000 tons of iron.

Lin Hao's 900-cubic-meter blast furnace can produce 700 tons of iron per day, with a theoretical annual output of 25 tons.

With so many military factories, large and small, all waiting for production, the annual output of 1.4 tons of iron was simply not enough.

The various machines and equipment brought by Lin Hao will inevitably greatly increase the output of weapons and ammunition while improving the quality of military industry. This further aggravates the problem of steel shortage.

However, the iron smelting problem will be solved with the construction of the 900 cubic meter blast furnace, so the supporting weapons processing capabilities will also be quickly updated with the mechanical equipment brought by Lin Hao.

The problem of iron smelting was solved, but the problem of steel shortage emerged again. So Lin Hao used mental marking to let Mi Lijian's people buy a batch of air separators.

Air separation unit is the core equipment for producing oxygen from air.

That’s right, Lin Hao is preparing to implement oxygen top-blown converter steelmaking technology.

Fortunately, Lin Hao had learned this in other film and television worlds before, so he was very familiar with using this technology.

It just so happens that among the equipment brought this time, there is a converter with a capacity of 80 tons. Once the oxygen top-blown converter is used and continuous production is carried out for 24 hours, the steel output can reach 3000 to 4000 tons.

However, the transformation will take a long time, so Lin Hao had already prepared a 1.5-ton electric arc steelmaking furnace.

An electric arc steelmaking furnace is a type of steelmaking equipment that uses the high temperature generated by an electric arc to melt scrap steel or molten iron.

A simple factory building has been built on the construction site and the electric arc steelmaking furnace was put in place yesterday.

Electric wires are now being pulled in from Nanye and Tangjiahui, and the pig iron support from Yangquan will be delivered soon.

As long as everything is ready, the first batch of special steel can be smelted, and then there will be no shortage of tool steel for the cutting tools needed on mechanical equipment.

Lin Hao came to the electric furnace factory, where the conditions were very simple, but fortunately the equipment was very small, with a diameter of 4.2 meters and a height of 3 meters.

Lin Hao also transferred some electricians and iron smelting personnel from Pingshan County and started special training today.

The large iron-making blast furnace in Nanping is under construction in full swing, and the electric arc steel-making furnace is also under construction in full swing. The electric furnace requires huge amounts of electricity.

Although there is a small 194kw power plant in Xibaipo at present, the maximum power generation can reach 70 kilowatts based on the installed capacity and motor efficiency of 130%.

If it runs 24 hours a day, the daily power generation is approximately 3120kwh.

At that time, electricity was needed everywhere in Xibaipo, and the electricity provided by the Xiuxiushui Power Station was not enough, so it was impossible to use it for industrial purposes.

Moreover, a 1.5-ton electric arc steelmaking furnace requires at least 600kwh. Based on 75 minutes per furnace, 19 furnaces can be smelted per day.

The daily electricity generated by the Xiuxiushui Power Station is only enough to smelt five furnaces, or 5 tons of special steel, which is not enough, so a special thermal power plant had to be built.

So Lin Hao built a small thermal power plant of 1000kVA next to the electric furnace, and the excess electricity can be supplied to other factories for use.

In order to speed up the progress, Lin Hao also secretly helped them meet the deadline.

Finally, half a month later, the thermal power plant was completed, the electric arc furnace was installed, and it entered the final debugging stage.

More than a dozen technicians have memorized the operating manuals and procedures by heart. As long as they practice operating them a few more times, Lin Hao will not have to worry about them in the future.

Later, under the guidance of Lin Hao, Nanping's 1.5-ton electric arc steelmaking furnace methodically smelted the first batch of molten steel.

But it was not very successful and could only be considered ordinary steel, failing to meet the standards of special steel.

Over the next three days, after dozens of smelting cycles, Lin Hao analyzed the composition of the molten steel, adjusted the process parameters in a timely manner, and summarized his experience.

Finally, they managed to smelt qualified special wear-resistant steel, which is specially used to make machine tool tool heads.

The industrial equipment in the liberated areas will not be short of cutting tools. Combined with the mechanical equipment brought by Lin Hao, the processing accuracy will inevitably be greatly improved.

After hearing the news, several big bosses came in person to congratulate them, which made the workers very excited.

This is a landmark event for the entire North China Liberated Area, marking that we can finally smelt special steel on our own.

And they have basically mastered the skills and techniques of electric furnace steelmaking. With these high-performance machine tool heads, they can not only improve the processing accuracy, but also shorten the processing time and greatly improve production efficiency.

Many workpieces that could not be processed in the past can now be made, and there is no need to worry about the problem of not being able to use the tool after the tool is worn out.

The rifling of artillery that could not be broached in the past can now be processed, and the yield rate of artillery shells and bullets will be greatly improved.

During this period, several exploration teams that went out to look for minerals also reported back that they had discovered several small and medium-sized copper veins.

Most of it is located on the surface and is very easy to mine. As long as there are enough people, mining can be done quickly.

From now on, the Red Zone will no longer need to ask the people to donate copper coins and copper pots.

Good news came back one by one, and this sense of changing history made Lin Hao very excited.

Unfortunately, the first blast furnace has not been completed yet. Fortunately, the preliminary construction started a month ago, and now all that remains is to install the equipment.

Even so, with the help of Lin Hao who worked privately, the installation would take at least three months.

Fortunately, someone was responsible for the construction of the blast furnace, so he didn't have to stay here all the time.

Except for the blast furnace, the other five small industries have basically taken shape.

All technical personnel participated in the entire construction process. As long as the technical standards are strictly followed in the future, it will not be difficult to promote it, so he does not need to worry too much.

Therefore, it was time for Lin Hao to leave.
After all, he has been stranded here for more than a month. The three major battles in the Northeast have begun. I heard that Jinzhou has been captured, and the next ones are Liaoxi and Shenyang. It is time for Lin Hao to return to the capital.

However, the night before Lin Hao left, everyone held a farewell party for him.

Over the past month, everyone has seen Lin Hao's efforts, and his abilities have been recognized by everyone.

At the farewell party, Lin Hao sang "My Motherland and I", which was well received by everyone.

Lin Hao did not cheat again after drinking and was finally sent to his room.

I don’t know who it was, but he not only helped him take off his clothes and pants, but also wiped his face and body, and finally~!

Oh, another sleepless night!
