There were seven or eight people behind Tang Hua, including Zhang Mingshan who invented the anti-encirclement system, Han Changxin who had been wronged before, and the others were engineers from the technical team of the rolling mill.
"Lao Zhang and Lao Han are outstanding members of the technical workers who dare to study and are good at studying," Tang Hua said, "as engineers, managing and supervising the operation of the factory and the execution of the process are only part of the job. How? Maybe in a factory, only the workers are innovating, but the engineers are working as supervisors?"
"Besides, engineers should make greater contributions in terms of theoretical knowledge and production experience. Because of the incident in the rolling mill some time ago, your thinking was messed up, so I will tell you a bigger one. Scientific research task, give it out."
Deng Fa and the secretaries, Tang Hua and the engineers and technicians sat in a large circle, and Tang Hua assigned the first scientific research task to the rolling mill:
"Upgrade the current 1700 semi-continuous hot rolling mill to a continuous or 3/4 continuous hot rolling mill."
Chapter 90, Changchun Special Photoelectric Machinery Factory
Tang Hua started the seminar on technological innovation, and the rest of the work was mainly carried out by workers and engineers.
By May 1955, Anshan Iron and Steel's monthly output had exceeded 5 tons, that is, it had reached the designed annual output of 20 million tons.Moreover, Anshan Iron and Steel has not carried out the transformation of the oxygen top-blown converter yet.
With such a large steel output, continuous hot rolling steel technology has the necessity and material basis.
Of course, this is only the primary goal of today's "grass seminar".Tang Hua has another purpose today:
Put factory leaders, workers, and technicians together for a meeting. In terms of technical direction, Tang Hua gave them a research goal; in terms of factory management, Tang Hua asked them to exchange opinions; in terms of factory environment, let the workers talk about their own requirements and ideas .
"Minister Tang, if we develop a semi-continuous hot-rolling mill, there will be a lot of roughing mills and finishing mills, which may be 500 meters long, and three-quarters continuous, then it will be more than 600 meters. Our factory can't fit it."
After discussing a general idea, an engineer raised his hand to ask a question.
"Don't talk about 500 meters and 600 meters, even if it is an 800-meter-long line, as long as it can be operated, the country can solve it," Tang Hua said with a smile, "Director Wang of your Iron and Steel Bureau is in Baotou to supervise the construction of Baotou Steel, so I will Come to give you this guarantee."
"Minister Tang, if you decide to change it, you have to stop a line, unload what needs to be unloaded, install what needs to be installed, and then debug. A few months have passed. What if the production task cannot be completed?"
Tang Hua and Deng Fa: "The state will adjust the plan for you."
……
The discussion of continuous hot-rolled steel technology leads to the future of the rolling mill, and from the rolling mill to the future development of the entire Anshan Iron and Steel Company.The meeting was attended by not only the secretary of the director of Anshan Iron and Steel Rolling Plant, but also the general manager and secretary of the party committee of Anshan Iron and Steel.The party secretary explained to the workers in the rolling mill Anshan Iron and Steel's plan for this year and next year, as well as Anshan Iron and Steel's goals during the first five-year period.Workers also tell their own stories, what level they are now, what plans they have for the future, and so on.
This far-reaching meeting, which was recorded in history later, can also be called the "tripartite exchange salon", and was interrupted by the smell of food in the cafeteria.Looking at his watch, before he knew it, it was time to get off work in the afternoon.
The scene of Anshan Iron and Steel getting off work is similar to what Tang Hua saw in Shanghai Iron and Steel Factory No. [-]. Groups of workers come and go, change clothes, go home, or go straight to the cafeteria. When entering the cafeteria, there is a smell of tobacco in the air Talk to the endless taste of the Northeast.
"Hello Secretary Wu." "Hello Director Li."
The factory manager and secretary also nodded to greet the workers.
Deng Hua: "Both Director Li and Secretary Wu seem to be people who often go to the cafeteria, and they are very skilled in taking food."
"Isn't that the general manager?"
They had already sat down in a row in a corner of the cafeteria. The general manager Ma Bin saw that he was discovered, so he stood up and greeted everyone with fists.But Secretary Wu coughed and reminded: "Dear workers, don't crowd around and watch, eat normally, eat normally."
Not long after, a few well-informed workers saw something tricky again: "The two rows in the middle of them can't be the Minister of Industry?"
……
"Secretary Deng, you are still the best. In five days in Anshan, you straightened out the relationship between the party and the masses in the eight factories." Tang Hua said to Deng Fa after the trip to Anshan Iron and Steel Rolling Plant.
"Well, it's still far from being straightened out." Deng Fa said, "This time, we have to clean up all the factories in this area. Anshan, Benxi, Fushun, Tieling, and finally return to Shenyang."
Tang Hua: "I will come to Anshan regularly in the future. This is an experimental field. The seeds were just planted today. If everything goes well, it will be harvested in three years."
Deng Fa: "Let's gradually summarize a set of systems in Anshan Iron and Steel, and then implement them nationwide."
Tang Hua didn't speak, but gave Deng Fa a thumbs up to show that he was right.

The mileage of Shenyang-Changchun railway is 310 kilometers, and the fastest train in this era can get there in 5 hours.
The process of building the Northeast of New China did not start in October 1949, but in November 10.Six and a half years have passed since the liberation of the entire Northeast. Looking at the factories, cities, and roads along the road from Shenyang to Changchun, it seems a bit like the scene when Tang Hua traveled around the Soviet Union in 1948-11.
On the double-track railway, from time to time, a train of freight trains/passenger trains crosses.After leaving Shenyang, there is a road close to the railway line, and many trucks run on it.After leaving Shenyang, it is recognized as the most famous big city in Northeast Tieling, where coal mines, thermal power plants and coal freight stations are in full swing.Further north, Kaiyuan and Changtu, which are smaller than Tieling, can also see many chimneys emitting smoke.
In 1954, China's industrial output value just surpassed the agricultural output value, but in the Northeast, the industrial output value was more than three times the agricultural output value, accounting for 76% of the total industrial and agricultural output value.
Moreover, the growth rate of agricultural output in Northeast China is also very fast. The national average growth rate of agricultural output value last year was 4%, while the growth rate of agricultural output value in Northeast China was 6.5%. This is the result of large-scale land reclamation and the use of agricultural machinery, chemical fertilizers, and pesticides.
The Northeast has coal, iron and water, and there are two large ports if the iron ore is of poor grade; there are cultivated land and forests, Heilongjiang is the number one granary in the country, and the Songliao Plain has billions of tons of oil.
How can such a treasure land be killed so that it can't be dealt with.
……
Changchun.
In the past year, Changchun Institute of Optoelectronics and Changchun Optical Instrument Factory merged and gave birth to two babies: Changchun Special Optoelectronic Machinery Factory (lithography machine factory) and Changchun Non-metallic Cable Factory (optical fiber factory).
Last year in Shenyang, when demonstrating the power of CNC machine tools produced by Shen Yiji to the chairman, Tang Hua said that within ten years, the base of industrial mother machines in China will be Shenyang; ten years later, this base will be Changchun.
This is talking about the lithography machine factory.
Not only is it China's industrial mother machine base, it may become the main industrial engine of the world in the future.
"In terms of equipment weight, the lithography machine only accounts for one-fifteenth of the entire chip production line, but it is indeed the most important part of the production line,"
Tang Hua, Wang Dayan, and Huang Kun were in the lithography machine factory, and they sighed as they looked at the newly assembled production line.
"From the perspective of minimizing transportation costs, it should be transported to the south, such as Shanghai, and set up a test production line there. But the lithography machine is too important, and it has just been trial-produced and needs to be adjusted and improved at any time, so We had to let other manufacturers of machinery and equipment transport their products to Changchun."
Last year, Wang Dayan and Changguang made one of the core components of the lithography machine - a high-precision lens system for industrial lasers.This is also the last stumbling block.The lens system is solved, and there is no technical bottleneck in the lithography machine that manufactures a non-contact bottom plate (mask).
Wang Dayan: "We have tried the lithography machine alone, and the exposure test shows that its potential may exceed the 10-micron process."
Huang Kun: "The lithography machine is half a step ahead, it doesn't matter, you wait for a while, let the craftsmanship of the bottom plate catch up."
Tang Hua: "For the non-contact lithography machine, the manufacturing industry of the bottom plate can also be slightly modified. Now some wear-resistant components are mixed into the bottom plate, which can be removed later. However, in order to prolong the life of the bottom plate, the bottom plate It may be possible to incorporate materials that are resistant to light and heat into the matrix."
Wang Dayan: "After the lithography machine and the backplane technology have caught up, the short board becomes..."
Huang Kun: "The short board becomes the photoresist formula and coating process."
Tang Hua laughed and said, "Just take care of your own business. And, remember what we're doing now: put this production line into full operation in the past few days."
……
The production line is assembled and the workshop is closed.Thorough cleaning, dust-free environment to start.The air filter and gas exchange system hissed to bring the dust particles in the air below the standard line.
Three people including Tang Hua and several workers put on closed overalls and masks and entered the workshop.
The workshop of the lithography machine is probably the cleanest air on the earth now, with constant temperature and constant humidity, but it does not mean that it has no smell.The strong smell of chemicals rushes straight into the nostrils. This is the final chemical cleaning of the surface of the monocrystalline silicon wafers shipped from Fushun.
