Chapter 847 of the main text: Strong strength

Next chapter

Zhang Zhenzhong was very interested in hearing that Dongxing Group was going to launch a 50,000-ton large die forging press, and many large forgings on McDonnell Douglas-82 needed large presses to complete, so he also deliberately took two days to rush to Bincheng with Lin Qiangsheng by plane.

There is a large area of tall factories in the northwest suburbs of Bincheng, which is already outside the new industrial zone, and two years ago it was a fertile land, and then the city allocated this piece of land to Dongxing Group.

Dongxing Industrial Company was founded, tall factories were built, large industrial equipment continued to gather here, the factories here are also different from those thin factories in the new industrial area, it seems extraordinarily thick and solid, and the workers here are also different from the people in the new area, most of them are middle-aged old industrial workers.

This is the heavy industrial base of Dongxing, where Shen Hong, a well-known mechanical engineering expert, was hired as the chief engineer of the project, and there are many retirees from the Third Machinery Department and his old friends and protégés working with him.

In the past few years, they have absorbed foreign advanced technology, designed and manufactured Dongxing's own large-scale hot-dip galvanizing unit, and designed an ultra-thin cold tropical steel continuous rolling mill, steel plate (chemical + physical) combined pre-cleaning equipment, and galvanized sheet finishing machine and tension leveling machine.

At present, Dongxing Industrial Co., Ltd. has established one set of large-scale hot-dip galvanizing unit, with a plate thickness of 0.3~2.0mm and a width of 800~1850mm, with an annual production capacity of 350,000 tons of galvanized coils.

Due to its wide application, the use of galvanized sheet in the construction industry and household appliances is also very high, highway guardrails, pipelines, light box advertising, housing plant construction, etc., household appliances are mainly used in air conditioners, refrigerators, washing machines, computer cases, microwave ovens, electric kettles, etc., and people's lives are almost inseparable from galvanized sheets.

In addition, the company's products also include cold-rolled low-carbon aluminum calming steel, which is the substrate of electro-tinplate, commonly known as tinplate, is an important packaging material, food, beverage, chemical, oil and other applications are wide, with ultra-low-carbon soft aluminum calming steel to produce tinplate, instead of aluminum plate to manufacture pressure beverage cans, saving aluminum resources, the thickness of the can wall has been as thin as 0.07mm.

Ultra-low carbon IF steel, also known as ultra-low carbon steel, has excellent deep drawing performance and no timeliness, and the world's advanced steel mills attach great importance to the development of ultra-low carbon steel.

The automotive industry under the Eastern Star Group is its pillar, and Lin Qiangsheng also strives to track the development trend of the world's automobile industry. In order to meet the needs of automobile weight reduction, material consumption reduction and fuel saving, the requirements for the strength of automotive steel plates will be higher and higher, and Dongxing has also invested a lot in steel materials.

Nippon Steel, JFE, ThyssenKrupp and other steel mills have mature experience in the chemical composition of steel, the content of inclusions and the control of each process. If you want to get these technologies, you need super high tuition!

In addition, the company's Beiman Special Steel also produces CQ~DDQ grade steel, EDDQ and color DDQ grade (i.e., IF steel), carbon junction steel, baking hardened steel, ultra-low carbon phosphorus-containing steel, and duplex high-strength steel.

At present, Dongxing's automobile companies are still the largest users of galvanized sheets, and these steel grades can only rely on imports in the past five years, and now they have basically met their needs. However, it is still necessary to expand the production capacity of various steel grades in order to meet the development needs of the expanding domestic automobile, construction, electrical appliances and other industries!

Lin Qiangsheng and Zhang Zhenzhong, chief engineer Shen Hong, who was directing the construction in the workshop, met, and after the two sides shook hands, Shen Hong asked with a smile: "Comrade Xiaolin, where are you from?" ”

The old gentleman is 80 years old, and he has long since retired, but after the reform, he still can't let go of the development of the motherland's heavy industrial equipment, and he has many opinions on the country's wanton introduction of foreign equipment, and has written letters to the top level of the central government, but unfortunately no one has listened to him anymore.

Since being hired by Lin Qiangsheng, the old man can be regarded as having a chance to take revenge, and it just so happens that Dongxing Group is going to launch a number of heavy equipment, which can be said to have greatly satisfied Shen Lao's wishes.

Lin Qiangsheng introduced to Shen Hong: "Mr. Shen, this is the person in charge sent by McDonnell Douglas to China, Mr. Zhang Zhenzhong, who presided over the McDonnell Dalwells 82 final assembly project of Shangfei!" ”

"Oh, welcome, Mr. Zhang! McDonnell Douglas 82 aircraft is going to be assembled in China, I heard, I have a question, is it that McDonnell Douglas will produce parts in China in the future? The scene was very noisy, and Shen Hong's senior's questions were also very loud.

Zhang Zhenzhong saw that the workers not far away were welding the foundation, sparks were flying, and he admired Shen Hongting, who was so old and came to the scene to command.

Nodding, Zhang Zhenzhong said: "In the future, the parts of McDonnell Douglas 82 will gradually be brought to China for production, and now China has signed a compensation trade agreement with us for landing gear doors and other parts, and I believe that Chinese companies will be able to get in touch with the production process of McDonnell Douglas 82 more and more!" ”

Shen Hong smiled and nodded, and said a few good words in a row, he took Lin Qiangsheng and Zhang Zhenzhong to visit the material components of the 50,000-ton large-scale single-cylinder die forging hydraulic press.

Zhang Zhenzhong looked at these large forgings and said in surprise: "I heard that to build a 50,000-ton die forging press, some parts need to be forged with a 30,000-ton press, and 30,000 to be forged on a 16,000-ton machine. ”

Although he is 80 years old, Shen Lao is not deaf and blind, he and Zhang Zhenzhong said: "Theoretically, this is the case, but there is a lack of large-scale forging presses in China, so we had to change our thinking and use the method of ants gnawing elephants, and use a 15,000-ton hydraulic press to forge these components little by little." ”

Zhang Zhenzhong asked suspiciously: "But won't this change the original structural stress, increase the complexity of the mechanism, and lack reliability guarantee, right?" ”

Shen Hong shook his head lightly and said with a smile: "There is always a way to overcome difficulties, there is great strength in numbers, and with the help of supercomputers, we have re-conducted structural stress analysis and reliability demonstration, and strive to make this big guy stand tall!" ”

Lin Qiangsheng also said: "After the completion of this 50,000-ton die forging press, the next project is the design and manufacture of the 80,000-ton double-cylinder die forging press!"

We have sufficient funds, I believe that with this equipment, the next large-scale die forging press will be easier, and the structure will be greatly improved, simplifying the mechanism, and this guy in front of him will be honorably laid off and rebuilt! ”

"Uh, that's amazing!" Zhang Zhenzhong was extremely shocked, looking at Lin Qiangsheng's confident appearance, Dongxing Group actually had such strong financial strength.

He thought that a young Chinese man could have a lot of courage, but he didn't expect that what he actually saw was far beyond imagination, in order to make 80,000 die forging presses, first build 50,000 tons of presses, and then dismantle them.

Shen Hong's predecessors continued to sigh: "Our country is now backward in the development of heavy equipment, in fact, it is always a matter of money, with enough funds, it is not difficult for a big country like ours to engage in such heavy equipment." ”

Lin Qiangsheng also nodded again and again, in the 21st century, why did China launch large-scale equipment one after another, it is not rich, in fact, materials, equipment, talents, etc., as long as the funds are sufficient, it is not difficult for China.

During the subsequent visit, Zhang Zhenzhong even saw a lot of foreign technicians, and when he inquired with them, he learned that these people were engineers and technicians from European and American powers, and even a few people were from large American technology groups such as General Electric and Westinghouse.

In addition, he also found that the hydraulic system technical scheme was actually composed of a group of technicians from Japan, and the Dongxing workers around them were humble to learn, and the spirit of these people's hard work in the design scheme left a deep impression on Zhang Zhenzhong.

After bidding farewell to Shen Hong's predecessors, Lin Qiangsheng took Zhang Zhenzhong to visit Dongxing's semiconductor factory and automobile engine factory.

Zhang Zhenzhong saw another scene, Dongxing's factory was like a copy of European and American companies, and he was very surprised that the rules and regulations here were quite familiar to him.

Generally speaking, the factory is aging, the equipment is backward, the personnel and technical level are low, the management is backward, and the most important point is the lack of understanding of the international advanced industrial standards, and even some leaders in charge feel that the Americans are extremely complicated, what airworthiness certificate, what ISO certification, McDonnell Douglas finally persuaded the US aviation department, some people on the Chinese side are still too troublesome and unwilling to do it.

Lin Qiangsheng looked at his expression and said with a smile: "When Dongxing was just established, our factory was no different from other enterprises in China. Later, I had the opportunity to go to the United States, and McKinsey Management Consulting established a long-term cooperative relationship, they helped me rebuild the company's organizational structure and management system, and we introduced a large number of European and American technicians, in the workshop to take the form of a gang of one, pass on the form of help, I require every employee must learn the skills of foreign masters. We set up a lot of night schools and training courses, and invited foreign technicians to take classes, and we have continued to do so until now. It can be said that Dongxing is a world-class company, and our employees are also the highest level in the industry! ”

"You hired McKinsey & Company, and you also carried out international standardization management?" Zhang Zhenzhong was very surprised when he heard Lin Qiangsheng's introduction, which coincided with his approach.

Lin Qiangsheng said with a smile: "Yes, although our main products are in the domestic market, we have been aiming at the international market standards, of course, we must be strict." ”

Zhang Zhenzhong was overjoyed when he visited Dongxing's factory, if he cooperated with Dongxing Group, it would be a very simple thing, the workers here are familiar with international production, which reduces a lot of training costs. (To be continued.) )
