Siheyuan: Craftsmen of a Great Country

Chapter 278: The assembly line model appears in the Sangang workshop

All members of the alloy steel research team dispersed to collect information from steel-making furnaces across the country in the hope of finding more formulas.

This method is a bit like finding a needle in a haystack and trying your luck.

But now that there are enough steel-making furnaces in the country and the base is large enough, there will always be miracles.

Jiang Chen had formulas for various alloy steels in his hand, but he couldn't throw them out at the beginning. Instead, he let the team try them themselves.

If this method has no results, Jiang Chen will come up with another method to conduct research on alloy steel.

The land prepared for farming has been deeply plowed with an excavator.

The ashes from burning weeds have been scattered on the ground.

Now Zhang Huajun and Zhang Cui are building canals to allow water brought up by water trucks to flow between the ground and facilitate water collection.

Once the canal is repaired and the weather gets warmer, we can start cultivating seedlings and growing vegetables.

Qualified parts of Sangang machine tools that have undergone strict inspection have been neatly stacked in the production workshop.

After a week of study, the smarter Shangguan Wan'er and Pan Wen have mastered the key points of Sansteel machine tool inspection and are able to complete the inspection work independently.

Zhou Xinjian also came to Sansteel Group early to participate in the commissioning ceremony and witness this historic moment.

He briefly talked about the significance and value of Sangang machine tools and wished Sangang machine tools all the best in production. It took less than five minutes in total.

She is better at talking and makes Zhang Cui very happy.

The workers responsible for production listened at their respective workstations and knew the mission and glory on their shoulders.

Jiang Chen left this area completely to Zhang Huajun and Zhang Cui.

Finally, it was Jiang Chen.

After all, the production of the first batch of Sangang machine tools is not only important to the laboratory, but also to the entire flower grower, and there is no room for sloppiness.

Unexpectedly, Jiang Chen's speech only contained four words. After a brief daze, the workers began to lower their heads to assemble.

He is the developer of Sangang machine tools and the direct person in charge of this assembly workshop.

Sangang Machine Tool was finally put into production and assembly.

Liu Xi, Shangguan Wan'er, and Pan Wen are ready. They are responsible for the quality inspection of machine tools.

Then there was Yang Weimin, who spoke a little more, almost ten minutes.

And You Fengxia, who also comes from a rural area, helps out from time to time.

But in the early stage, Liu Xi decided to come over and watch by himself to avoid any accidents.

Both of these two people are from rural areas, so it is still possible to grow some money as a banker.

Monday, April 3th.

He walked to the center, glanced at the people who were waiting, and said slowly: "Start production!"

The first person to speak was Zhou Xinjian.

The ceremony was very simple, consisting of speeches by several leaders.

Not long after they made several successful developments at Sangang, they have been practicing the assembly of Sangang machine tools on templates for the past two months and have become very proficient in this work.

They have a clear division of labor.

Some teams are responsible for combining small parts into larger components.

There are several such groups, and each group is only responsible for the assembly of one of the components.

For each group, the assembled parts are named.

Such as hydraulic group and gearbox group.

Each team is composed of multiple workers, and in the middle is a conveyor track with a fixed device that moves slowly.

Each worker only has one or a few simple actions to install the parts he needs to install into the corresponding position.

The crawler then delivers it to the next worker, who continues his work.

After all the parts are installed and the components are assembled, the last person on the right will remove the components and use the testing equipment equipped by the team to check whether the components they assembled are working properly.

After checking that there are no problems, the assembled parts will be placed together.

Each assembly team has one or more relatively more versatile free agents. When a worker has something to do or needs to go to the toilet, they can step in and complete his work in time.

There is a dedicated internal transfer team in the workshop. They are responsible for delivering assembled parts to the final machine tool assembly team, and are also responsible for delivering assembled machine tools to the refueling team, and finished machine tools to the quality inspection department.

The assembly team is responsible for installing the previously assembled components into the correct positions to form the final machine tool.

After the machine tool is assembled, it needs to be transported to a special place to add lubricating oil and other operations so that the machine tool can work smoothly.

After completing this, it will be sent to Liu Xi Shangguan Waner and other places for quality inspection.

Quality inspection, in addition to checking whether there are any errors in the assembly of the machine tool itself, also opens the machine tool to test whether the machine tool is operating normally, whether the gearbox is set correctly, etc.

Jiang Chen’s requirement is that every machine tool must be tested in the early stage.

After the quality is stable, the system will be changed to random inspection.

Based on the output of two hundred units per month, approximately eight machine tools need to be inspected every working day. Two people can perform inspections to do this work more carefully.

After the inspection is completed, workers will engrave the serial number and transport it to the warehouse to wait for shipment from the factory.

The entire production workshop is actually composed of countless subdivided assembly lines to form a large human-enabled assembly line. The connection and production between each process are basically completed by humans.

Anyway, Jiang Chen was responsible for everything from training to assembly, so he tried it in this manufacturing workshop, which was more suitable for the assembly line model.

The reason why the previous attempt took a month was to find the most suitable crawler running speed, the balance point for reasonably dividing the production process according to time, and the tacit understanding between each team member and between each team.

Judging from the current situation, things seem to be good.

It was also the first time that Zhou Xinjian saw such a production model. He couldn't help but widen his eyes and observed carefully.

After a long time, he slowly said: "Xiao Jiang, your production method is quite smooth, it seems to be pretty good."

Jiang Chen smiled and said: "It's not bad. Let's do a test. Using this method to produce can increase production efficiency by 50%."

Zhou Xinjian was stunned: "How much more?"

It wasn't that he didn't hear clearly, he just wondered if he heard it wrong.

Jiang Chen once again gave an affirmative answer: "50%."

Yang Weimin asked: "So this is a new model?"

Jiang Chen said: "It doesn't count as a new model, because the previous steel rolling mill actually divided the work according to types of work. From this perspective, it doesn't count as a new model."

"And I will divide labor more thoroughly, simplify the work I am responsible for, and make production smoother and more efficient."

"Each person is responsible for one or several processes, and everyone jointly completes the production of a component. From this perspective, it is a new model."

Yang Weimin said: "With this model, why not conduct a pilot project at the No. 3 Steel Plant? We also need to improve efficiency."

Jiang Chen said: "This model is more suitable for manufacturing plants, but it is not that meaningful for steel rolling mills."

"Furthermore, this model requires that our products must be standardized and the parameters of all parts must be unified. Sangang machine tools have been designed this way from the beginning, so they can be used quickly."

"The steel rolling mill has been operating for many years, and everyone has developed their own production methods. Sudden changes may be counterproductive."

"It's just that this model has a huge hidden danger that makes me afraid to really make it public."

Yang Weimin felt a little regretful when he heard that the steel rolling mill was not suitable.

Zhou Xinjian asked: "What's the hidden danger?"

Jiang Chen looked around: "This is not the place to talk. Find a place later and let's have a good chat."

Zhou Xinjian nodded: "No need to be late, let's do it now."

All methods that can improve production efficiency are what the Ministry of Industry needs most, and he doesn't want to wait.

Yang Weimin said: "Then, go to my office?"

Jiang Chen said: "Don't you watch the production here?"

Zhou Xinjian said: "Anyway, the Sangang machine tool won't be able to produce it for a while, and it won't run away if we leave it here. Let's talk about this model first."

Jiang Chen nodded: "Okay, let's go!"

His long-planned assembly line model may soon be on the stage of history.

Of course, it may also be rejected by the Ministry of Industry, and only the assembly workshops of Sangang Machine Tools will be allowed to use this model.
