In the context of the rise of China's industry, Taiyuan Heavy Industry Oil Film Bearing Branch has been fighting in the field of heavy machinery manufacturing as a struggler and entrepreneur, striving to make up for the shortcomings of national industrial products and break the monopoly of foreign technology. Too heavy oil film bearing products have gone through a difficult process from scratch, from small to large, and from large to strong. Deduced a wonderful story from Chinese manufacturing to Chinese creation.

"Too heavy oil film bearing products have high finish, and the surface is so smooth that ants can't climb them." This is an evaluation of a foreign expert on too heavy oil film bearings, and it is also the impression that too heavy oil film bearings left on the outside world.

As the heart of modern mechanical equipment rolling mills, oil film bearings play a very important role in the development of the steel industry. Taiyuan Heavy Industry Oil Film Bearing Branch, as the only company in China engaged in the research and development, design and manufacturing, sales and service of rolling mill oil film bearings, has a pivotal position in China's heavy machinery industry.

Work hard to fill the domestic gap

Recently, the reporter came to Taihe Oil Film Bearing Branch and saw the roar of machines in the production workshop, and the workers were full of energy. "We are working overtime to weld the oil-film bearing bushings that are needed in the Fangchenggang project of Liugang." Workshop worker Lu Pengfei proudly told reporters that only they can produce this product.

Indeed, Taiyuan Heavy Industry has proud capital. As a representative product of domestic machinery manufacturing, Taihe oil film bearings have been leading the pace of industry innovation.

As the heart of modern rolling mills, oil film bearings can be widely used in metallurgy, mining, power and other fields. In the early days of the founding of New China, the only oil film bearing products in our country could only be provided by the former Soviet Union. At that time, industrial equipment designed and produced by ourselves could be used as soon as possible and became the wish of industrial workers.

In the mid-1950s, Taichung was responsible for the development of oil film bearings. With only books published in the former Soviet Union for reference, it opened the road of independent design and hard work. The older generation of too heavy people boldly invented and decided to start with the cone and bushing of the core parts of the rolling mill oil film bearing, and continue to explore trial production.

In 1958, Taizhong successfully trial-produced my country's first set of φ750×560 oil film bearing taper bushing spare parts, ending the history of my country's failure to manufacture oil film bearings. In the early 1960s, in order to meet the demand for wide and thick plates in the national defense fields such as ships, tanks, and high-pressure boilers, my country decided to build a 4200 wide and thick plate production line for Hebei Wuyang Iron and Steel, in which oil film bearings were required for key components. At that time, this large-scale equipment in Wuyang was called "the king of rolling mills", and the design and manufacture of oil film bearings faced great difficulties in terms of specifications and technology. Too Heavy came forward and successfully developed the φ1300 oil film bearing, which was installed in Wugang in 1978, and it is still playing a role today.

In 1980, Taizhong developed my country's first set of "static-dynamic rolling mill oil film bearings" according to market demand, which once again filled the domestic gap, and my country became the third country that can independently design and manufacture this equipment.

Independent innovation, breaking technical barriers

Since the 1980s, China's machinery industry began to cooperate more and more with foreign countries to produce advanced products. In 1985, Taizhong signed a 15-year rolling mill oil-film bearing technology trade license cooperation agreement with a well-known American oil-film bearing design and manufacturing company, but the other party only agreed to introduce manufacturing technology, and the core design and operation technology refused to transfer, especially foreign countries in the 1980s. The "keyless structure oil film bearing" technology that has been developed in the 1940s has never been authorized, and the production drawings of the old technology simply cannot meet the production needs of modern rolling mills.

The technological lag made Too Heavy frequently restricted. At that time, the newly launched hot rolling mill projects in China all used a complete set of imported equipment, and Too Heavy could not get orders. In addition, Taizhong also needs to pay a technical service fee of 10% of the oil film bearing sales revenue to the American company every year, even if it is self-developed and designed, it will also pay 4%.

In order to break through the development bottleneck, Taizhong strives to innovate independently, overcome difficulties and diligently tackle key problems. Advanced designs and processes such as "keyless oil film bearing", "hydraulic locking", "new type of sealing", and "static-dynamic complete oil supply system" have been overcome. In 1995, Taihe Oil Film Bearing successfully obtained the oil film bearing contract for the 2800 rolling mill of Jiuquan Iron and Steel Company under the condition that the technical performance of the foreign product was basically the same and the price was only one-third.

In 2000, the US company that cooperated with Taizhong put forward more stringent conditions during the renewal negotiations: using technology to buy shares, neither investing nor allowing the "TZ" trademark to appear, technology and sales are all done by the US.

"Doesn't this treat Taizhong as a foundry?" Shen Fuchang, who was the manager of Taizhong's oil film bearing branch at the time, was unacceptable. In the end, Taizhong refused to continue to cooperate with American companies. In order to prevent the development of too heavy oil film bearings, the United States has also established a wholly-owned factory in China and threatened: "I have American technology, Chinese prices, and see who the market will choose in the end."

"At that time, everyone was holding a sigh of relief, and we must show it to foreigners." According to Yang Huirong, a designer and current director of the Institute of Oil Film Bearing Branch of Taizhong Group, recalled, in order to save time, scientific research The staff do not go home after get off work, and they are enthusiastic about researching key technology in the office. When the time is late, they sleep in the office for a while and get up and work. Hard work has paid off. After day and night efforts, Taizhong bearing technology has developed rapidly, and the gap with foreign advanced technology has been narrowing.

The technical problems restricting the development of too heavy oil film bearings have been solved, and the market will be developed next. In 2001, Taizhong finally seized the opportunity and successfully signed the first complete project contract after the expiration of the license agreement-Baosteel's 1780 hot strip project order. This order was not easy to come by. At first, the foreign partner of the Baosteel project team was not optimistic about the performance of Chinese products and decided to use imported equipment. After learning about the situation, Shen Fuchang rushed to Shanghai to introduce the technical performance and product quality of the heavy oil film bearing to the experts and the project team, and formed a product-related statement overnight. Shen Fuchang's sincere attitude impressed Baosteel. Baosteel arranged five staff from the project headquarters to inspect the production conditions of Taihe Oil Film Bearings at the first time, and formed a report that Taihe could be fully competent in technical and quality after the field inspection. In this way, too heavy to fight a "beautiful turnaround" with strength.

Go abroad and open up the international market

With the needs of market development, Taizhong has built the world's largest specialized and modern oil film bearing new-type manufacturing base. By optimizing the manufacturing process and updating the production equipment, the main geometric accuracy of the heavy oil film bearing has been improved to the μ level, and the products include various specifications and types.

The good news of the technological innovation and breakthrough of too heavy oil film bearing one after another: in the Shouqin 4300 wide and heavy plate rolling mill project, too heavy broke the situation that China could not design and manufacture oil film bearings with 10,000 tons of rolling force; In the rolling mill project, Taizhong applied the keyless thin-wall optimized bearing to the hot-rolled strip rolling mill for the first time; in the 4700 wide and heavy plate rolling mill project of Nangang, Taizhong designed and manufactured the oil film bearing with the largest carrying capacity in the world. Chong Ye has obtained 26 patented technologies for oil film bearings and became the drafter of China's "Roll Oil Film Bearing Standards", providing reference for selection of oil film bearings of various specifications worldwide.

At the same time, the market share of too heavy oil film bearings continues to expand, and gradually goes abroad. At the end of 2017, Xie Hanjiang, a distributor of the Taihe Oil Film Bearing Export Project, came to Kazakhstan, a country along the “Belt and Road” initiative, to expand international trade. English is not useful here. Chinese-Russian dictionaries and English-Russian dictionaries have become Xie Hanjiang’s teachers to open up the market. He works 8 hours a day and learns 10 hours of language. In the end, Russian became his third language, which is too heavy for business. Expanded to Ukraine and Russia.

In addition to continued efforts in marketing, oil film bearings have also achieved the ultimate in product services. The excellent product quality makes Taihe Oil Film Bearings dare to make a solemn promise of "one-time use, lifelong responsibility" to customers, and provide customers with free operation training, regular experience guidance, after-sales maintenance and other services.

Today, Taizhong "TZ" brand oil film bearings account for 85% of the domestic market for strip and medium and heavy plate rolling mills. The products are exported to 15 countries and regions, and even sold to Germany and Japan, two countries with advanced oil film bearing technology. Even under the influence of the new crown pneumonia epidemic this year, the company has handed in a beautiful report card: In the first half of the year, the domestic market successively won the bids for oil film bearing projects such as Jingang 1580 hot rolling and Jinma Steel 1580 hot rolling, with a total value of about 8,000 Ten thousand yuan. The international market has successfully signed multiple export contracts for ArcelorMittal from Kazakhstan and JSPL oil film bearing spare parts from India, with a total value of approximately 15 million yuan.

The success of too heavy oil film bearings also forced the sales prices of similar products from two other well-known companies in the world to drop again and again, and eventually fell to less than one-third of the original price, reducing costs and developing independently for Chinese steel companies. Make a positive contribution.

Looking to the future, exploring smart transformation

At present, my country's manufacturing industry is in the process of transforming and upgrading from traditional manufacturing to intelligent manufacturing. Taizhong Group takes "refinement, internationalization, high-end, and intelligence" as the transformation and development direction, and puts forward the vision of "building a modern intelligent equipment manufacturing enterprise with world-class competitiveness". Through careful analysis of the domestic and international rolling mill production line market situation, The demand for spare parts in the market forms a development roadmap in the new era.

"Currently, thin slab continuous casting and rolling oil film bearing products have broad market development prospects." Cheng Dongsheng, general manager of the oil film bearing branch of Taiyuan Heavy Machinery Group Co., Ltd., told reporters that according to new developments in the industry, the company started technical research at the first time The project has been established and the new products developed have been successfully applied to the production field. The next step will be to continuously optimize and improve product performance in the "intelligent monitoring and development of oil film bearings" and other aspects based on the actual user feedback, and to further promote new products in the market The use of. At the same time, the company will strengthen the anti-corrosion and anti-corrosion ability of parts and materials according to the factors of relocating and building factories in the steel industry, and carry out targeted technological optimization and innovation.

"The company will further expand the scope of business coverage, with the international market accounting for 30% as the goal, relying on the existing three international markets of India, the Russian-speaking region, and Southeast Asia, to promote the expansion of the branch's international territory." Cheng Dongsheng said, through and Foreign general contractors establish strategic cooperation to form a way of strategic investment, actively develop South Africa, Turkey and other foreign steel users, and promote the internationalization of branch products.

"In the future, oil film bearings can realize intelligent diagnosis, remote monitoring and other functions, and can provide users with customized products according to different needs of users, provide users with better service experience, and contribute to the high-end development of Chinese manufacturing." Talking about the future Cheng Dongsheng is full of confidence in development. (Economic Daily News, China Economic Net reporter Liang Jing, correspondent Xing Wenjing
