Master Alloys

I-master alloy yintsimbi esisiseko efana ne-aluminiyam, i-magnesium, i-nickel, okanye ubhedu oludityaniswe nepesenteji ephezulu ngokuthelekisa enye okanye ezimbini zezinye izinto. Yenzelwe ukuba isetyenziswe njengemathiriyeli ekrwada lishishini lesinyithi, kwaye yiyo loo nto sibize i-master alloy okanye i-alloy esekelwe kwiimveliso ezigqityiweyo. I-master alloys iveliswa kwiimilo ezahlukeneyo ezifana ne-ingot, iipleyiti ze-waffle, iintonga kwiikhoyili kunye nokunye.

1. Ziziphi ii-alloys eziphambili?
I-master alloy yimathiriyeli ye-alloy esetyenziselwa ukuphosa ngokubunjwa okuchanekileyo ngokucokisa, ngoko ke i-master alloy ikwabizwa ngokuba yi-casting master alloy. Isizathu sokuba i-alloy master ibizwa ngokuba "yi-master alloy" kuba ineempawu ezinamandla zemfuza njengesiseko sezinto zokuphosa, oko kukuthi, iimpawu ezininzi ze-master alloy (ezifana nokusabalalisa i-carbide, ubungakanani bengqolowa, isakhiwo somfanekiso wesibuko esincinci. ), Nokuba kubandakanywa iipropati zoomatshini kunye nezinye iimpawu ezininzi ezichaphazela umgangatho weemveliso zokuphosa) ziya kuzuzwa kwi-castings emva kokunyibilika kunye nokugalela. Izinto ezikhoyo ezisetyenziswa ngokubanzi zibandakanya ubushushu obuphezulu be-alloy master alloys, i-alloys yentsimbi ekwazi ukumelana nobushushu, i-dual-phase master alloys, kunye ne-stainless steel master alloys eqhelekileyo.

2. Master Alloys Isicelo
Zininzi izizathu zokongeza i-master alloys ekunyibilikeni. Olunye usetyenziso oluphambili luhlengahlengiso lwemizobo, okt ukutshintsha ukwakheka kwentsimbi engamanzi ukuze kuphunyezwe ukucaciswa kwemichiza. Esinye isicelo esibalulekileyo kulawulo lwesakhiwo - ukuphembelela i-microstructure yesinyithi kwinkqubo yokuphosa kunye nokuqiniswa ukuze ihluke kwiipropati zayo. Iipropati ezinjalo ziquka amandla omatshini, i-ductility, i-conductivity yombane, i-castability, okanye ukubonakala komhlaba. Ukubala kwisicelo sayo, i-master alloy idla ngokuchazwa ngokuthi "i-hardener", "i-grain refiner" okanye "i-modifier".
