Entering the main body of the market 丨 What makes this old state -owned enterprise rejuvenated "new youth"

Xinhua News Agency, Harbin, July 8th: What makes this old state -owned enterprise rejuvenated "new youth"

Xinhua News Agency reporter

From traditional manufacturing to new energy of wind power, cultivate new growth points; from imitation innovation to original innovation, realize domestic replacement imports; from once losses to comprehensive turn losses, profits have increased significantly ... Youth ", realize" rebirth "? The reporter recently entered China Yizhong Group Co., Ltd. to find out.

"Old state -owned enterprise" embrace new industries

Entering the Qiqihar wind power blades manufacturing park in Heilongjiang Province, in the wide factory area, "lying" a 76.6 -meter -long and 17.5 -ton wind power blades. This is the first wind power blade to go offline by China Yizhong Longshen (Qiqihar) Composite Materials Co., Ltd. on May 25 this year.

In the workshop, technical workers Zhang Delong and workers are assembling wind -powered machine window status detection equipment. "After networking with the computer, whether the data related to wind power meets the standard, you can know through this set of equipment." Zhang Delong said.

As a leading enterprise in the domestic heavy equipment manufacturing industry, China was built in 1954 and is one of the 156 key projects during the "Five -Year Plan" period in my country.

In April 2021, the construction of the Qiqihar Wind Electric Leaf Manufacturing Park was started. "We only used 13 months, and the first wind power blades were successfully offline, laying the foundation for the future mass production." Said Xu Ge, general manager of China Yizhong Longshen (Qiqihar) Composite Materials Co., Ltd.

During the production of leaves, technicians broke through the difficulties and mastered advanced manufacturing technology in a short period of time, which not only reduced the weight and cost of the blades, but also met the rigidity of the blades and high -power catcher, high power, and high stability.

"The success of the first wind power blades marked that China has basically formed a full -industry chain system covering technology research and development, equipment manufacturing, wind farm construction, and operation and maintenance services." Said Liu Mingzhong, Secretary of the Party Committee and Chairman of China Yizhong Group.

After the formation of the entire industrial chain in China, the host (motor) capacity can reach 600 units; the annual production capacity of the fan can reach about 840; Reacked 200.

The wind power blade manufacturing project not only becomes China's re -growth point, but also comprehensively improves the core manufacturing and supporting capabilities of wind power technology and equipment in Qiqihar and surrounding areas, forming a modern energy equipment industry cluster with location advantages.

Independent innovation breaks through the "card neck" problem

Entering the "country's heavy weapon" in China, a high -red plant in China, and entering the high -red factory building, people suddenly "smaller". Looking up, I saw that above the seven or eight floors high, the huge "car" across the beam moved back and forth, making a huge roar.

In the workshop of the water pressure machine forging factory, a giant iron shear of 10 meters long and more than 5 meters wide, with a scorching alloyed steel ingot in front of the hydraulic machine, Mars shot in the puppet forging sound, and soon It reduced a large circle.

Liu Boming, the chief skill master of China on the side, stared at the forging parts, constantly changing the command gesture, controlling the strength of the lower head of the hammer and the degree of forging transformation ...

A guy like an inverted teapot is a forged pump shell for the main pump of my country's nuclear reactor cooler coolant main pump in China.

Prior to this, the coolant pump shell was made of castings made of steel water, and the mechanical performance was unstable. After three years of exploration, China successfully produced the main pump shell of stainless steel in 2021, solving the prominent problem of forging pump shell quality for a long time.

In recent years, China has formed an open technology innovation system based on national strategic demand and market demand, overcome a number of key core technologies, and achieved a "card neck" breakthrough in some forward -looking and disruptive technology fields.

For example, the successful development of a million kilowatt -for forging low -pressure rotor has broken the situation of a unique situation of foreign companies and realized domestic replacement imports.

Guan Yongchang, the general manager of China's No. 1 Machinery Co., Ltd., said that in the past one million kilowatt -level forging low -pressure rotor can only be imported from abroad, each of which has more than 80 million yuan. Now domestic replacement imports have been replaced, which has fallen to more than 20 million yuan.

"In the past, we have always followed imitation innovations. Now we have not had to do it abroad. We have always stood on the front line of breaking foreign technology monopolies and product monopoly. Nie Yihong, general manager of China Yizhong Science and Technology Department.

In the past ten years, China has re -designed, studied and manufactured 72 first new products, and developed 94 new technologies, all filled with domestic products and technology gaps, and 8 items to solve the "card neck" problem of scientific and technological achievements came out.

Deepen the reform and welcome the new life

In the cylinder block class of a heavy medium -sized equipment manufacturer in China, the milling worker was holding the operating equipment in the hand, and his eyes stared at the cylinder block product for surface refinement.

"In the past, the industrial workers were promoted to senior technicians to the 'ceiling'. Now through reform, work enthusiasm is higher." In 2020, Chi Hai was promoted from senior technicians to a master of chief skills in China. Essence

China also established Chihai Studio for him. He led members to carry out technical research, obtained more than 50 scientific and technological achievements, and created more than 5 million yuan in benefits.

Chi Hai benefited from the three system reforms of China's personnel, employment, and distribution.In response to technical talents, China has specially implemented the two series of "hundred talents" and "chief" of "big country" and "chief", with a subsidy quota of up to 10,000 yuan per month.Since 2012, China ’s economic benefits have continued to decline. In 2016, losses have reached 5.7 billion yuan, which is one of the largest losses and the highest degree of difficulty in the year.

In May 2016, China ’s determination to break the wrist with a strong man firmly held the three systems to reform the“ cattle nose ”.The development environment of "can".

Liu Mingzhong said that China achieved a comprehensive turn of losses in 2017. From 2018 to 2021, the total profit increased by 424.95%, and operating income increased by 200.43%.(Reporter Liu Wei, Chen Cong, Wang Jian, Liang Dong)
