Steel Sand Castings

I-steel sand castings yizingxenye zensimbi ezikhiqizwa inqubo yokuphonsa isihlabathi. I-steel castings iyinhlanganisela yenqubo yokubumba kanye nensimbi yezinto zensimbi. Abakwazi nje ukuba nesakhiwo esiyinkimbinkimbi okunzima ukukuthola ngezinye izinqubo zokwakha, kodwa futhi bagcine izakhiwo eziyingqayizivele zensimbi, ngakho izingxenye zensimbi zokuphonsa zinesikhundla esiphakeme esibalulekile ezintweni zokwakha zobunjiniyela. Ezisekelweni eziningi, ukulingwa kwensimbi kukhiqizwa ngokuyinhloko ngalezi zinqubo ezimbalwa zokuphonsa: ukufakwa kwe-investimenti, ukukhishwa kwegwebu elilahlekile, ukuphonswa kwe-vacuum, ukuphonswa kwesihlabathi kanye nokusakazwa kwesihlabathi esimbozwe inhlaka.
Insimbi ye-Cast ingahlukaniswa ibe yinsimbi ye-cast alloy kanye nensimbi ye-carbon iron ngokusho kwamakhemikhali ayo, futhi ingahlukaniswa ngensimbi yensimbi, insimbi ekhethekile, ubunjiniyela kanye nokusakazwa kwesakhiwo kanye nensimbi ye-alloy cast ngokusho nezici zayo. Insimbi ye-alloy ingahlukaniswa ngensimbi ephansi ye-alloy (ingqikithi ye-alloy element ingaphansi noma ilingana no-5%), i-cast alloy steel (ingqikithi yezakhi ze-alloy ingu-5% kuya ku-10%) bese iphonsa insimbi ephezulu ye-alloy (ingqikithi ye-alloy). izakhi zinkulu noma zilingana no-10%).
