Kukandira tekinoroji
Kunyunguduka
Kuwana tembiricha yepamusoro uye yakaderera sarufa yakachena inopisa simbi ndiyo kiyi yekugadzira yakakwira mhando ductile iron. Midziyo yekugadzira yemumba inonyanya kuenderana nekapu, uye simbi inopisa haisi pre-desulfurization kurapwa; Izvi zvinoteverwa nekuchena kwakanyanya kwenguruve iron uye hurombo hwecoke quality. Simbi yakanyungudutswa yakanyungudutswa mucupola, yakanyungudutswa kunze kwechoto, uye yobva yapiswa uye inogadziriswa muchoto chekupinza. MuChina, kuwonekwa kwesimbi yakanyungudutswa kuumbwa kwave kuchiitwa nevacuum yakananga kuverenga spectrometer.
kuumba
Iyo mhepo inokanganisa kuumba maitiro zviri pachena kuti yakakwirira kune yevhu jecha kuumba maitiro, uye inogona kuwana yakakwirira-chaiyo crankshaft castings. Iyo jecha mold inogadzirwa neiyi maitiro ine hunhu hwekusina rebound deformation, iyo inonyanya kukosha kune yakawanda-kukanda crankshaft. Vamwe vanogadzira crankshaft mudzimba kubva kuGermany, Italy, Spain nedzimwe nyika kuti vaunze maitiro ekuumba mhepo, asi kuunzwa kwemutsetse wese wekugadzira ingori nhamba diki yevagadziri.
Electroslag casting
Electroslag remelting tekinoroji inoshandiswa pakugadzirwa kwe crankshaft, kuitira kuti kuita kwe cast crankshaft kufanane neye forged crankshaft. Uye ine hunhu hwekukurumidza kusimudzira kutenderera, yakakwira simbi yekushandisa rate, yakapusa michina, yepamusoro chigadzirwa kuita uye zvichingodaro.
