I-calcium silicon alloy grade

I-Silicon-calcium alloy iyingxubevange ehlanganisiwe eyakhiwe izakhi ze-silicon, i-calcium nensimbi.Kuyi-deoxidizer eyinhlanganisela ekahle kanye ne-desulfurizer.Isetshenziswa kabanzi ekukhiqizeni insimbi yekhwalithi ephezulu, insimbi enekhabhoni ephansi, insimbi engagqwali kanye namanye ama-alloys akhethekile njengama-alloys asekelwe ku-nickel kanye nama-alloys asekelwe ku-titanium;ibuye ifaneleke njenge-ejenti yokufudumala ye-converter steelmaking workshops;ingasetshenziswa futhi njenge-inoculant ye-cast iron kanye nezithasiselo ekukhiqizeni i-ductile iron.

sebenzisa

Kokubili i-calcium ne-silicon zinobudlelwane obuqinile bomoya-mpilo.I-calcium, ikakhulukazi, ayinakho nje kuphela ukuhlangana okuqinile nomoya-mpilo, kodwa futhi inobudlelwane obuqinile nesibabule ne-nitrogen.Ngakho-ke, i-silicon-calcium alloy iyinhlangano enamathelayo eyinhlanganisela efanelekile ne-ejenti ye-desulfurization.Ingxubevange ye-silicon ayinakho nje kuphela ikhono eliqinile le-deoxidation, futhi imikhiqizo ye-deoxidized kulula ukuntanta nokukhipha, kodwa futhi ingathuthukisa ukusebenza kwensimbi, futhi ithuthukise i-plasticity, umthelela wokuqina nokuqina kwensimbi.Njengamanje, ingxubevange ye-silicon-calcium ingangena esikhundleni se-aluminiyamu ukuze kukhishwe i-deoxidation yokugcina.Kufakwe kunsimbi yekhwalithi ephezulu.Ukukhiqizwa kwezinsimbi ezikhethekile nama-alloys akhethekile.Isibonelo, amamaki ensimbi njengensimbi yesitimela, insimbi ephansi ye-carbon steel, nensimbi engagqwali, nama-alloys akhethekile njengama-alloys asekelwe ku-nickel nama-alloys asekelwe ku-titanium, ama-silicon-calcium alloys angasetshenziswa njengama-deoxidizer.Ingxubevange ye-Calcium-silicon nayo ifanelekile njenge-ejenti yokufudumala yama-workshops okwenza insimbi yabaguquli.Ingxubevange ye-calcium-silicon nayo ingasetshenziswa njenge-inoculant ye-cast iron kanye nesengezo ekukhiqizeni i-nodular cast iron.
