A master alloy isimbi yepasi sealuminium, magnesium, nickel, kana mhangura yakasanganiswa neyakaenzaniswa yakakwira chikamu chimwe kana zviviri zvimwe zvinhu. Iyo inogadzirwa kuti ishandiswe seyakagadzirwa neindasitiri yesimbi, ndosaka takadaidza master alloy kana based alloy semi-akapedza zvigadzirwa. Master alloys anogadzirwa mumhando dzakasiyana senge ingot, waffle mahwendefa, tsvimbo mumakoiri uye nezvimwe.
1. Chii chinonzi master alloys?
Iyo master alloy ndeye alloy zvinhu zvinoshandiswa kukanda zvine chaiyo kuumbwa kuburikidza nekunatsa, saka master alloy inonzi zvakare casting master alloy. Chikonzero nei master alloy ichinzi "master alloy" imhaka yekuti ine yakasimba genetic zvimiro sehwaro hwezvinhu zvekukanda, kureva, akawanda maitiro eiyo master alloy (senge carbide kugovera, saizi yezviyo, microscopic girazi mufananidzo chimiro. ), Kunyangwe kusanganisa zvivakwa zvemuchina uye zvimwe zvakawanda zvinokanganisa kunaka kwezvigadzirwa zvekukanda) zvinozogarwa nhaka kucastings mushure mekunyungudika nekudururwa. Zvishandiso zviripo zvakashandiswa zvakanyanya zvinosanganisira alloy master alloys, kupisa-resistant simbi master alloys, dual-phase master alloys, uye akajairwa Stainless simbi master alloys.
2. Master Alloys Application
Pane zvikonzero zvakawanda zvekuwedzera master alloys kunyungudika. Chishandiso chimwe chikuru kugadziridzwa kwekuumbwa, kureva kushandura kuumbwa kwesimbi yemvura kuti ione iyo yakatsanangurwa kemikari. Chimwe chakakosha chikumbiro ndechekudzora chimiro - kupesvedzera iyo microstructure yesimbi mukukanda uye kusimba maitiro kuitira kuti isiyanise zvimiro zvayo. Zvinhu zvakadai zvinosanganisira simba remagetsi, ductility, magetsi conductivity, castability, kana kuonekwa kwepamusoro. Kuverenga pakushandiswa kwayo, master alloy inowanzotaurwawo se "hardener", "grain refiner" kana "modifier".
