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. Masana’antar karafa ne ke kera ta don amfani da ita a matsayin danyen kayan aiki, shi ya sa muka kira master alloy ko kuma tushen kayan da aka kammala. 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 masu ƙarfi a matsayin tushen kayan simintin, wato, yawancin halaye na babban allo (kamar rarraba carbide, girman hatsi, tsarin hoton madubin microscopic), har ma da kaddarorin injina da sauran halaye masu yawa waɗanda ke shafar ingancin samfuran simintin gyare-gyare) za a gada su zuwa simintin gyare-gyare bayan remelting 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 ƙayyadadden 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 akan aikace-aikacen sa, ana kuma ambaton babban allo a matsayin "hardener", "mai tace hatsi" ko "mai gyara".
