Chapter 210 The extraordinary significance of the new rolling mill
After such a long period of hard work, my country's first independently developed and manufactured new 2800mm four-roll rolling mill has finally come out!
Although this new rolling mill, temporarily named Longteng No. [-] by Lin Shengli, is a medium-sized equipment in the current rolling mill.

But the meaning it represents is extraordinary.

You know, before the 70s, it was very difficult for me to copy or modify medium and large-scale mechanical equipment!

Personnel, equipment, materials, technology, etc., are all troubling the development of our equipment manufacturing industry all the time!
It is even more difficult to design and manufacture a medium and large mechanical equipment by yourself!

Even if there are bugs in Lin Shengli's era now, and he can come up with relevant drawings of advanced large-scale machinery and equipment, based on our current manufacturing level, we will not be able to produce them in a short time!

Take the production of a large rolling mill with a diameter of more than 4000 mm as an example. Even if there are drawings, the manpower, material resources, and financial resources required are very difficult for flower growers at this time!
Wotu's first truly self-developed 4200 mm large rolling mill was designed in 12 and was not completed and put into production until September [-], which took a full [-] years.

In order to build such a large-scale mechanical equipment, enterprises and departments such as the Ministry of Metallurgical Industry, the First Machinery Department, the Forty-Nine City Iron and Steel Design and Research Institute, Deyang Erzhong, Dongfang Electric Machinery, etc. were gathered together. It was almost a nationwide effort. , after hard work and hard work, this large rolling mill was completed, from design, production, installation to final production!

As for the new four-roller rolling mill that Lin Shengli is currently copying, it is based on the rolling mill imported from the Bear Country. Apart from the appearance, which is still [-] to [-]% similar, the inside of the entire equipment has been modified by Lin Shengli. It was beyond recognition.

In order to adapt to the current mechanical manufacturing level of our rabbit, Lin Shengli made some magical changes, taking some parts that are technically difficult, require precision machining, or high-performance raw materials, without affecting the overall performance. A temporary replacement method.

But even so, the technological content contained in this new four-roll rolling mill is still about 20 years ahead of the world level. Even if we no longer make technical improvements and upgrades to this new rolling mill from now on, this rolling mill will also It can be used until at least the mid-80s without falling behind!

Moreover, the new 2800mm four-roll rolling mill developed and copied by Lin Shengli is exactly the type of rolling mill that our rabbit can produce and manufacture on its own at this stage and meet the needs of use.

What's more, the new four-roller rolling mill developed by Lin Shengli can no longer just be said to be imitated, but manufactured.

Because the overall modification range of this new four-roll rolling mill exceeds 60% of the original model, and even reaches 70%, and it has also achieved national production of all parts. It can be said that it is self-designed. A brand new piece of equipment manufactured.

The successful development of this new rolling mill marks a qualitative leap in my country's design and manufacturing level of some mechanical equipment, filling the gap where my country cannot independently produce steel rolling equipment!

This has enabled us to transcend the stage of transformation to imitation in some fields of machinery manufacturing, and directly come to the stage of independent production and manufacturing.

It can be said that with the large-scale mass production and application of this new rolling mill, our country will get rid of the disadvantageous situation of being dependent on and lagging behind related developed countries in certain steel rolling technologies.

Now this is a new 2800mm four-high rolling mill assembled from parts produced on the assembly line of the pilot workshop of the Fourth Branch Plant.

After Lin Shengli directed the workers and masters to put the overall equipment in place, under the watchful eyes of all project team members and the master workers in the workshop, Lin Shengli slowly turned on the machine's operation switch.

As the first steel plate was rolled out of the new rolling mill, everyone present burst into warm cheers and lasting applause!
Everyone present was so excited and joyful that they had to cheer loudly and applaud vigorously to release their inner joy!

You know, only three months have passed since receiving the task of developing a new imitation rolling mill.

And in just three months, they produced the first new rolling mill independently developed in my country!

It can be said that they have accomplished a feat in the history of machinery manufacturing!

As the general person in charge of the research and development of this rolling mill, Lin Shengli was hugged constantly by the enthusiastic workers around him.What's more, they want to throw Lin Shengli up to celebrate.

If Lin Shengli hadn't had quick eyesight and quick hands to avoid the people grabbing his arms and legs, he still doesn't know how long he would have been thrown in the air by the enthusiastic crowd!
"Ahh! Great, we have our own rolling mill!"

"Yes, yes, we finally have our own equipment!"

"Long live the florist!"

Some elderly workers could not contain their inner emotions and burst into tears.

"Victory, did you see it? We succeeded!"

"We really did it!"

"We built our own rolling mill!"

Director Yuan was also very excited at this time. He grabbed Lin Shengli's arms with both hands and kept shaking them.

"Yeah! Yeah! Yes, we succeeded!" Lin Shengli was surrounded by extremely excited people and was grabbed by Director Yuan's arm. He could only keep nodding in response.

In fact, Lin Shengli was feeling the same joy as everyone else at this moment, but he was not as excited as everyone else!
Because from the very beginning, when he proposed the idea of ​​replicating the rolling mill, Lin Shengli knew that the replicating work of this new rolling mill would be successful.

Moreover, if it were not for the purpose of adapting this new rolling mill to the large-scale mass production of the production line, Lin Shengli would not have to set up a pilot workshop, conduct assembly lines and standardize operations.

If there weren't so many delays and just produced a prototype, Lin Shengli would have completed the task of replicating the rolling mill long ago.

After venting his excitement loudly, Director Yuan took Lin Shengli's arm and said, "Shengli, the new rolling mill has been successfully developed. Please tell everyone a few words."

"Yes, Director Lin, please say a few words."

"Yes, Director Lin, please give me a few words."

"Yes, everyone, please be quiet. Can you let Director Lin say a few words to you?"

"it is good!"

"Pah~pah~pah~pah pah!"

After everyone responded, everyone clapped excitedly and asked Lin Shengli to say a few words to everyone.
