The science and technology of our country makes a technology now more and more the maturity of development, and present tense often has good news to come out outwards, the message weighs what had finished 150 tons of weight at present to course of Chinese Academy of Sciences tries hard for years is the biggest stainless steel on the world of annular forging cast.
Somebody feels this is done not have probably too fancy, probably because know its effect not quite, the biggest stainless steel on this kind of world is annular forging is to invite the application of nuclear energy more safe, everybody knows to once had produced the problem of nuclear leak, whole casts this kind of iron hoop, have the iron hoop forging that does not cast at traditional section, this lets him can develop its property better, also can let nuclear energy when be being used more safe.
This diameter of annular forging has 15.6 meters, weight achieved 150 tons, this kind casts the annular forging that gets such heavyweight is pass whole first finish without what solder, previously even if the country of nuclear energy of other more early research is the means that casts with section is finished. They are to use cent to be paragraphs small casting, although this kind of casting also can be finished apply, but compared with whole cast for the function that still casts unlike its whole is more safe, and more durable.
The method of annular forging casts the biggest stainless steel on this kind of world first namely an a lot of circlet form forging, whole passes extruding and become again next. The annulus propping up that he regards our country as part of core of group of electric machinery of the 4th acting nucleus, not only can susceptive pressure is very great, and have safe safeguard very much, OK on the structure susceptive weight is as high as 7000 tons. Compared with before the means that section casts, this kind casts time limit for a project more short, cost is relatively low, and the material performance of the position that break solder is excellent.
How to rectify system to create a difficult problem that this kind is as high as 150 tons of heavy annular forging once was the world, researcher is in the metallic place of our country Chinese Academy of Sciences passed tens of year after tough effort, eventually research and development the metal that belongs to our country to be achieved formerly is built shape technology, eventually will this once the whole world inspects the world of whole of tremendous and annular cast undertake forginging. Our country with small made old way realize whole to cast not only, what still achieved each shares on composition organization function is perfect and unified.
150 tons of stainless steel are annular of forging forging the technology can have a lot of for use range, it is the respect in nuclear energy not only, and can apply in spaceflight, the significant technical level such as aircraft carrier, production technology also has used real life now in. Good, introduce here for everybody today, we issue first phase good-bye!
