These days, Shanghai Electric Machine Factory first independent manufacture key equipment for the nuclear island - Hongyanhe Unit 1 reactor components are ready acceptance of the factory, which is China's first generation of improved equipment to achieve all 2 localization.
Even more gratifying is that traditional manufacturing enterprises with innovation greatly enhance the core competitiveness and energy levels: from the past 5 years the production of a reactor component to achieve a record year last year, producing four sets of production capacity by 20 times; Revenue from sales of 8,000 million in 2005, glue stick an increase of over 780 million yuan last year, about 5 years ago, 10 times.
Reactor component is the core of nuclear reactor equipment, from more than 10,000 parts form, all using nuclear grade stainless steel and nickel-based alloys, is a precision machining, precision welding in one of the large equipment. Its main function is to "reinforce", support and fixed fuel assembly; "shock", a reasonable lower water channel reactor vibration; "protection" for the pressure vessel, "wear" on the radiation protective clothing. Sun Zhongfei executive director of a machine to tell journalists, and its precision machining, precision welding and high precision assembly requirements, the key parts of the error if more than a fraction of a human hair, have scrapped; related to a clearance process to ensure foolproof can not reinvent the wheel ... ...
For example,glue gun key components of reactor components - guide tube, which has more than 500 solder joints, internal circular, square shapes are different. The difficulty of welding technology, past master in the hands of foreign enterprises. Is it a machine to buy the technology, the result out of the price of foreign experts, arrogantly rejected the request of Chinese enterprises. To this end, a machine tool employees hold in the breath, after more than four years, ending with the completion of 48 research trials, and create a "symmetrical - Order - Cross," the welding method to overcome the problem, so directed to tube manufacturing the design requirements.
In this regard, more than 30 years experience in manufacturing industry Sun Zhongfei quite feeling, between the traditional manufacturing industries and advanced manufacturing, and there is no unbridgeable gap and barriers. Traditional manufacturing industry to develop, the key is the introduction of technological innovation and industrial transformation, the key is innovation. Not only the technology to be innovative, ideas, models, production and management but also innovation. A bit more, "a fresh recruit" master the intellectual property rights to the extent possible and the most advanced technology, international standards or even to grasp the right to speak. Only in this way, the "platter" to strong, to occupy the high end.
To this end, a machine tool company is now actively introduce, digest and absorb the third generation of nuclear power manufacturing technology, the technology to keep pace with international standards. They have completed major projects AP1000 reactor state components, AP1000 control rod drive mechanism, HTR 12 research projects and other projects. Meanwhile, the promotion of new technology, but also strive to improve the level of automation, equipment, numerical control rate of 70%, using robots instead of part of the manual. Actively foster our own design capability, to provide technical support for the integration of complementary and natural resources.
This year, a machine tool company to the existing production capacity of 4 sets on the basis of units completed 6 sets of manufacturing tasks. Expansion Phase II construction is completed, will form the 2012 annual average of 8-10 sets of units, their production capacity ranks first in the world.
