The research and development of large-scale forging presses must be based on the principle of “mainly based on me†and implement a combination of “production, learning, and research†technology lines, based on independent development; at the same time, we must also adhere to the principle of “step-by-step introduction and use for the outside worldâ€. "The open technology strategy. The long-standing problem of “a lack of high-quality valve forgings†in China's large-scale casting and forging industry is about to become a history.
Twenty-two Metallurgy has solved the technical bottleneck in the production of high-caliber high-pressure high-pressure forged valves, and has found an independent and innovative technological route for the domestic production of nuclear power and ultra-supercritical thermal power valves.
China Metallurgical Precision Forging Co., Ltd. has already started its 120M multi-directional die forging press and it will be completed and put into operation by the end of 2012. "We will speed up the R&D of 300M multi-directional die forging presses, meet the demand for localization of the largest caliber nuclear power and ultra-supercritical thermal power valve body forgings, and gradually enter the international market," said Liu Enguo, general manager of China Metallurgical Precision Forging.
Filling the domestic gap At present, China's valve manufacturing industry still has a big gap between the high-end technology and the highest international level. "One is the lack of high-quality castings and forgings; the second is the backwardness of high-end valve testing methods," said Song Yinli, general manager of China General Machinery Industry Association valve branch.
In order to meet the needs of the nuclear power, thermal power, petroleum, and petrochemical industries, China needs to import a large-caliber, high-pressure, high-pressure, forged valve of USD 3 billion annually. Although the small-caliber forging valve can be produced autonomously, it is also a process of free forging or monolithic forging. After the inner hole is processed, not only the material consumption is serious, but also the processing resources are wasted.
As a result, the advantages of multi-directional die forging are obvious. It can process complex parts that can not be completed in a normal die forging at a time, solves the defects of the traditional process for manufacturing vacuum valve flange welding, improves material utilization, reduces subsequent processing volume, and saves man-hours.
On April 2 this year, China Metallurgical Precision Forging Co., Ltd. used a multi-directional die forging technology to forge a vacuum valve body that was mainly used for the manufacture of nuclear fuel, filling the gap in the field in China. "We have a stable market demand for this type of product," said Peng Xinying, deputy general manager of China Nuclear Su Valve. On May 11th, after China Metallurgical Precision Forging Co., Ltd. observed the hot test process of a 40M multi-directional die forging press, Zou Shihao, general manager of Harbin Power Station Valve Co., Ltd., was very excited: “We will not only be the technology. The beneficiaries are also advocates."
Large-scale valve forgings realize autonomous "The successful development of multi-directional die forging presses has solved the problems that conventional structural presses cannot overcome. It is the world's most advanced precision, high-efficiency and energy-saving forging equipment technology." Liu Enguo said that the company is studying The constructed 300M multi-directional die forging hydraulic press will realize the autonomous production of large-diameter high-temperature and high-pressure valves and replace imports. The device can also be used to develop components needed for aerospace applications such as aircraft landing gear and rocket nozzles.
Twenty-two metallurgy is people's impression of doing metallurgical engineering construction. Whether in the forging industry or the valve industry is not considered a veteran. The problems that have long plagued the development of the valve industry have been conquered by this "latecomer"?
China Metallurgical Precision Forging and Multidirectional Die Forging were joined in 2006. Twenty-two Metallurgical Technology won the bid for the factory construction and equipment installation and commissioning project of Inner Mongolia Northern Heavy Industry Group Co., Ltd. 360 project. The 360 ​​mega cattle steel pipe vertical extrusion machine in this project Weighing more than 2,700 tons, the engineering is more difficult than ever.
The valve for industrialization is a product that involves a large number of categories, complex varieties, and large quantities. The domestic valve industry standard research started late and the standardization degree of the product is not high, which undoubtedly also brought difficulties to the promotion of multi-directional forging technology. To this end, Chengdu Chenggao Valve Co., Ltd. chairman Ding Wei recommended: "The valve should be a large quantity of a wide range of standard products, standardization does not exist the problem of technical leakage, unified standards, will provide for multi-directional die forging technology A vast space for development."
The state may stipulate that the valve on the equipment must use multi-directional die forging technology in bidding for large-scale project equipment. Otherwise, it cannot participate in bidding, which objectively will play a role in enhancing the competitiveness of the valve industry.
China Metallurgical Precision Forging Company has signed with China Nuclear Su Valve Technology Industrial Co., Ltd. and Other units? The cooperation agreement established the intention of co-developing products in the fields of nuclear energy, nuclear power key valves, ultra-supercritical thermal power, and key petroleum and petrochemical valves, and has taken steps in multi-directional die forging and market matching.
The “Multidirectional Forging Technology Promotion and Application Work Committee†will also be established in Dalian, Liaoning Province in June. The committee will study and formulate forging design standards and specifications, coordinate the industry's required forgings, and formulate multi-directional die forgings design and manufacturing standards. Promote its industrialization process.
