Babban Alloys

Babban gami wani ƙarfe ne na tushe kamar aluminum, magnesium, nickel, ko jan ƙarfe wanda aka haɗa tare da babban kaso ɗaya ko biyu na wasu abubuwa. Ana ƙera shi don amfani da shi azaman albarkatun ƙasa ta masana'antar karafa, kuma shine dalilin da yasa muka kira master alloy ko tushen gami da gama gari. Ana samar da manyan allunan a sifofi daban-daban kamar ingot, farantin waffle, sanduna a cikin coils da sauransu.

1. Menene manyan alloys?
Babban alloy abu ne da ake amfani da shi don yin simintin gyare-gyare tare da daidaitaccen abun da ke ciki ta hanyar tacewa, don haka babban allo kuma ana kiransa babban allo. Dalilin da ya sa ake kiran babban alloy "master alloy" saboda yana da kaddarorin kwayoyin halitta a matsayin tushen kayan simintin gyare-gyare, wato, halaye da yawa na babban alloy (kamar rarraba carbide, girman hatsi, tsarin hoton madubi na microscopic. ), Ko da ya haɗa da kaddarorin inji da sauran halaye masu yawa waɗanda ke shafar ingancin samfuran simintin gyare-gyare) za a gaji su zuwa simintin gyare-gyaren bayan an sake narkewa da zubowa. Abubuwan da ake amfani da su da yawa sun haɗa da babban zafin jiki na alloy master alloys, ƙarfe mai juriya mai zafi, babban allo mai nau'i biyu, da na al'ada bakin karfe master gami.

2. Babban Alloys Application
Akwai dalilai da yawa don ƙara manyan allurai zuwa narkewa. Ɗayan babban aikace-aikacen shine daidaitawar abun ciki, watau canza abun da ke cikin ƙarfe na ruwa don gane ƙayyadaddun sinadarai. Wani muhimmin aikace-aikacen shine sarrafa tsarin - yana rinjayar microstructure na karfe a cikin simintin gyare-gyare da ƙarfafawa don ya bambanta kaddarorinsa. Irin waɗannan kaddarorin sun haɗa da ƙarfin injina, ductility, gurɓataccen wutar lantarki, siminti, ko bayyanar ƙasa. Ƙidaya kan aikace-aikacen sa, ana kuma ambaton babban allo a matsayin "hardener", "mai tace hatsi" ko "mai gyara".
