carbon steel blind flange/class 150# flange

Forging process generally consists of the following processes, namely the selection of high quality steel billet blanking, heating, forming, cooling after forging. Forging process method have free forging, die forging and forging of membranes. Production, according to the size of the forging quality, production batch much choice different forging method.

Free forging low productivity, machining allowance, but simple tools, generality is big, so it is widely used in forging shape simpler single piece and small batch production of forgings. Free forging equipment has air hammer, steam - air hammer and hydraulic press, etc., suitable for small, medium and large forgings production respectively. Die forging productivity is high, the operation is simple, easy to realize mechanization and automation. High precision die forgings size, small machining allowance, forgings of fibrous tissue distribution is more reasonable, can further improve the service life of parts.
