China has long been re-host, supporting the development of light, resulting in large-scale forging and hydraulic parts, seals and other infrastructure constraints have been a part of our development of large complete sets of equipment bottlenecks. "These parts do not look, but its relatively substantial economic benefits, but also has a strong strategic significance." Refer to the recent introduction of the adjustment to revitalize the equipment manufacturing industry planning, the first group of heavy machinery is quite rich with emotion, Chairman Wu. He told reporters, "We hope to further refine the planning, implementation, at the same time as soon as possible a satisfactory mechanism for large-scale forging of the technology level play a real role."

April 18, industry and information technology within the Department of a person to disclose to our reporter, on the improvement of China's large-scale details of Casting and Forging is independent study, will be introduced soon.

Casting and Forging the lack of large-scale high-end

In recent years, increasing the country made great efforts and equipment. A heavy, double, too, CITIC Heavy Industry Casting and Forging and other large enterprises have also invested heavily in technical research, especially to enhance large-scale nuclear forging forging technological level and production capacity, China has been forging and forming a large-scale reactor pressure vessel manufacturing base.

Following the completion of a single layer of the Group of 15,000 tons free forging hydraulic press, two-group successfully developed 16,000 tons after free forging hydraulic press, the 16,500 tons of heavy free forging hydraulic press CITIC Heavy Industries and 18,500 tons of hydraulic machines is also actively building. CITIC Heavy Industries in particular, of 18,500 tons hydraulic machine, whether standard or technology, are currently the only worldwide. Million tons of hydraulic machines and other high-end devices in succession, this is bound to the world's major equipment manufacturing industries have an impact on the pattern.

"Although the capacity of our equipment has far exceeded by Japan and France steel Bururi shuttle, but has not yet been forging some form of high-end large-scale production capacity, product demand can not support." Industry source said.

"In the nuclear island with one million kilowatts-class ultra-supercritical thermal power units, a number of very large forgings and special materials, special structure, such as large-scale power plant is still a shortage of Casting and Forging, can not meet the needs of the domestic market, especially some high-quality, high demand for large-scale Casting and Forging domestic supply is not, such as ultra-supercritical one million kilowatts, 60 kilowatts of extrusion equipment. "China Heavy Machinery Industry Association, honorary chairman of Wang Jianye that.

It is reported that more than a kiloton thermal hydrogenation reactor wall, represented by large-scale pressure vessel forgings, semi-portfolio crankshaft, the tail shaft and rudder stock, represented by large-scale marine Casting and Forging, 5500 millimeters in heavy plate rolling mill roller bearings, represented by The single 100-ton forging more than a large roller bearing and high speed steel roll material represented by the special roll forging, also needs to be improved independently of manufacturing capacity. At the same time, one million kilowatts-class conventional island nuclear power plants in the overall low pressure rotor forgings also still rely on imports.

"Casting and Forging in China only in some large-scale trial stage, from manufacturing to used items, there is a long way to go." During the interview, one of China Guangdong Nuclear Power is not no worries insiders told reporters that China's nuclear power construction has entered a rapid development period, "the urgent demand for large-scale manufacturing enterprises Casting and Forging brought great pressure. How can we ensure quality and delivery time will be a very serious problem."

Three feet of frozen cold day

"Three feet of frozen cold day." Heavy Casting and Forging, referring to China's domestic problems, many respondents have this feeling, "This is a problem in the industry over the years, more complicated."

"I think the problem or system." Wang Chien-yeh said that "heavy machinery factory in China basically has its own large-scale production Casting and Forging Division, Casting and Forging a result, large-scale production did not fully compete in the market, some enterprises rely on its parent company, their effectiveness has not fully played out. three production bases in Japan also can not keep up with a business. This shows that production capacity could not well planned. "

As for high-end product development difficult, Wang Chien-yeh that was due to a lack of complete sets. "For example, we also need large-scale forging large crane hung up, resulting in low efficiency. Some enterprises hydraulic machine, hydraulic press machine with the next operation does not match, although the results of equipment, but failed to play its due role. "

"It's also not enough attention the past, there is too little investment in research and development relationship." Jianye Wang pointed out that "since the last century since the eighties, a number of R & D funded solely by the national investment in R & D investment is not in place it will be difficult to carry out. The State should set up an expert group carefully studied the crux of the development of the industry, what lack of what? How much money in the end? then certified the results of the deployment of the overall planning. "

China Machinery Industry Federation, vice president, said Cai Wei-Tze: "At present, China is already very advanced equipment, the gap is still software. Heavy Casting and Forging in the large-scale fire, water, nuclear power, large forgings, such as bearing problems not fully resolved. thermal processing much more than cold, it also includes long-term accumulation of experience, technology that can not see, touch not the technology. with the world level, we also lack a lot. "

"We still lack technology and the equipment can play the advantages of real talent." China Heavy Machinery Industry Association, Deputy Chief Engineer Fu Lee stressed trees.

Rules and suggestions to the parties

February 4 of the State Council examined and approved in principle the adjustment of the equipment manufacturing industry revitalization plan, the "Casting and Forging to enhance large-scale, basic components, processing aids, special raw materials, ancillary products, such as the skill level, solid foundation for industrial development." "Now the full support of the national development of China's large-scale Casting and Forging, I hope the entire industry can take full advantage of this rare opportunity." Fu Shu-li said.

Heavy Casting and Forging to enhance existing skills, Jianye Wang believes that the production of large forging company as soon as possible from the mother completely separated, directly face the market test. In this way, will it be possible through policy guidance and financial support to carry out large-scale mergers and acquisitions Casting and Forging units, and gradually form an internationally competitive enterprise groups Heavy Casting and Forging.

At present, China has developed a million tons of hydraulic machines, such as the world's cutting-edge equipment, it is imperative that as soon as possible to improve the matching ability. "If large-scale forging the necessary supporting research means the process of matching heavy forgings forging non-contact measuring device, such as size, these measuring devices and equipment, aids the quality of large forgings and forging forging a decisive impact on efficiency." Some experts have proposed .

"Heavy Casting and Forging solve the current bottleneck is the key technology to strengthen basic research and general technical support." In a letter to the Department of Public Works Secretary of equipment "on the improvement of China's large forging capacity of self-report" China Heavy Machinery Industry Association said that "as soon as possible to develop a reliable manufacturing process parameters Heavy Casting and Forging, Casting and Forging really large-scale production from the 'necessity' to 'freedom', thus reducing loss of material waste. To this end, the proposed as soon as possible to establish state-level large-scale forging common technology research, and forging a clear large-scale scientific research funding channels for special applications. "

In addition, the interview, there are companies that "Heavy Casting and Forging, especially one million kilowatts of nuclear power Heavy Casting and Forging level of scientific research is very difficult, long-term, urgent needs, there are a lot of the first pieces of the risk of material failure, which is expected to vote the failure of the loss of up to several million dollars to even thousands of yuan, is expected to vote solely by the companies is not quite reasonable to assume, wants the state to build the first large-scale pieces of Casting and Forging material risk compensation fund.

Within a re-told a reporter, and now the domestic nuclear power equipment manufacturing in France and the United States there are two sets of standards, "This gives manufacturers a lot of trouble, each owner has its own standard, which virtually made to increase the equipment the difficulty of. "He said that the manufacturers hope that the urgency of nuclear power equipment standards as soon as possible, and with the Design Institute, together with property owners to participate in equipment design, manufacturing and other related standards development.
