The door of the courtyard house has been welded dead

Chapter 980 Technology Transforms Productivity

In the office of the third workshop.

Six or seven middle-aged people in their fifties were called in by the workshop director.

Should I say it or not, it can be said that these people in front of me are all beings who can walk sideways in this workshop. I don’t know how many disciples and disciples they have brought out.

“To make a long story short, without wasting everyone’s time, all of you masters are masters of technology in the welding industry, and I trust your craftsmanship~!”

"I believe everyone has heard about the construction of a family area in the steel rolling mill. To be honest with you, the city and district have basically arranged the preliminary work properly, but before that, we still have to face a small Level~!”

As he spoke, Li Feng unfolded the drawings of the steel truss bridge designed by the technical department and laid them out on his desk. The masters who were already listening attentively became more interested when they heard the news about the new family area.

Li Feng stepped aside and motioned for them to come forward and take a look at the drawing first. Design is design, and whether it can be completed depends on whether these master craftsmen have relevant experience.

This bridge, let alone a hundred years, will have a service life of more than thirty years after at least a millennium, which is about the same. In the future, with the development of the economy, such iron bridges will naturally Replaced by new bridge.

"Deputy Director Li, is this a steel bridge?"

Some of the old masters held up their spectacles and some held their cheeks. After observing for a moment, they finally looked at Li Feng.

"Yes, the factory decided to design and build a steel bridge with a span of 32 meters. After all, it is our own family area, and it is not good to burden the government~!"

"Now we just need this last step. After all, our factory has never had this kind of large-scale steel structure welding work before. I think we still have to learn from the experience of all the masters to see if the factory can solve this problem by itself~! "

Li Feng smiled and nodded, and motioned to the master chefs to find a stool to sit down. Then he took out cigarettes from his pocket, one each, and handed them over, as if asking for advice.

"Building bridges and repairing roads has been a good deed since ancient times. Deputy Factory Director Li, whether it is for the housing of our factory or for the convenience of others, as long as the materials are in place, we will go out of our way to do it." Solved~!”

"Old Ding, don't worry. I, Old Zhu, have a word to say. I'm afraid they didn't pay attention when they were designing. At this stage, most steel bridges are still riveted, such as the Yangtze River Bridge in Jiangcheng~!"

Seeing the old man patting his chest and trying to take over the job, another old man wearing glasses pondered for a moment and then spoke. Li Feng remembered that this Master Zhu once came up to the stage to receive instructions when Director Yang was there. Awarded.

"It's okay. After all, this is the first time for our factory to do it. It's a good thing that Master Ding has such courage. It's a good thing to have courage in bridge construction, but we can't ignore safety. Master Zhu, I want to hear your opinion?"

First, he calmed down the impatient Master Ding, and then turned his attention to Master Zhu. He really hadn't paid attention to this detail.

"I have been to Jiangcheng. A few years ago, I went up to see the Yangtze River Bridge in Jiangcheng with a learning attitude. However, the main connection parts were basically riveted. I also asked about it later because the steel they used was Carbon A3 steel~!”

"High carbon content, poor weldability?"

When another old master heard the end of the words, his first reaction was to point out the shortcomings of A3 steel. The masters here are all masters above level seven, and they are all good at welding. The professionalism was revealed at all times.

"So, for the construction of bridges, we have to consider the material. If it is alloy steel, we can consider welding. If we still choose high-carbon steel, my suggestion is riveting. There is no problem with riveting technology, but our factory does not have a pneumatic riveting machine. I'm afraid this problem still needs to be solved, and the riveting workers also need to be trained~! "Good guy, I originally thought that the 32-meter bridge and the steel rolling mill were easy tasks, but I didn't expect that in the end, there was a new problem.

Li Feng had never heard of pneumatic riveting machines. He had seen pneumatic cannons, and riveting workers. Where to get them was another question.

"The material must be corrosion-resistant, have strong load-bearing capacity, the yield point cannot be low, and it must also have some toughness for stress balance. This kind of alloy steel may not be easy to make~!"

Another old master took a long puff of cigarette and held it in his lungs for a long time. When he spit it out, the other road was blocked again~!

"Yield point, does it mean yield? Can high-yield marine alloy steel be used to build bridges?"

He seemed to hear a familiar word in his ears. Li Feng looked at the masters who were racking their brains and tentatively looked at a few people. He already had some plans in his heart.

"That's perfect. However, Deputy Director Li, yield point and yield strength are two different things. Marine steel has a high enough yield strength and excellent welding performance, but we don't have a quota for this material. The steel factory comes out The alloy steel billets were sent to the shipyard, it’s not our turn~”

Master Zhu gave a wry smile. The steel materials used for ships are much higher than those used for civilian use. Just the steel rolling mill cannot compete with any domestic shipyard. If you want to take advantage of others, The higher authorities will not easily agree to use the food to build bridges.

"Boilers, with steel-making boilers, we can refine the materials we need ourselves. Recently, Shougang's 30-ton oxygen top-blown converter is very popular~!"

Another old master said somewhat sourly that the Hongxing Steel Rolling Plant, not to mention the shipyards, even the Shijingshan Steel Plant in the capital, could sweep the entire capital.

The speaker has no intention, the listener has intention~!

Li Feng suddenly remembered that the visiting delegation from the fourteen countries years ago had gone to Moroge to purchase large-scale iron towers from the sovereign country. Why didn't Shijingshan Iron and Steel Works work hard to get the large oxygen top-blown converter back as soon as possible.

If they don't get it back quickly, how can the steel rolling mill take over their second-hand converter? They are busy here and there, and the breakthrough is still at the source, which is restricted by the upstream smelting.

Electric furnaces are unaffordable for steelmaking, and large-scale top-blown oxygen converters cannot be ranked. Second-hand 30-ton small converters can still be used at home.

When he thought about the power required by the converter, Li Feng remembered what Director Zheng said before that the load of the transformer had reached its limit.

I didn’t expect that traveling through time would end up being like playing a construction game, linking link to link. If you want to light up the technology tree of a bridge, you also need to light up a series of previous supporting foundations, which is very troublesome.

"The technical research and development department in the factory has technical information about alloy steel. In this regard, I will communicate with the superior department and coordinate trial production with Shijingshan Iron and Steel Plant. You must also be familiar with the new type of steel first. Science and technology still need to be transformed into Productivity~!”

Boilers, electricity, material formulas, everything seems to be shackles that restrict the steel mill from making further progress. If it wants to transform and upgrade, it must solve this series of problems.

After coming out of the welding workshop, Li Feng figured it out. As he said, technology can only promote the progress of steel rolling mills when it is transformed into productivity.
