Silicon-manganese alloy yog cov hlau uas muaj ntau yam. Silicon-manganese nitride yog siv dav hauv kev lag luam thiab muaj cov khoom lag luam loj. Nws yog ib qho kev siv ntau deoxidizer hauv steelmaking.
Tsis tas li ntawd, nws tseem yog tus neeg sawv cev txo qis rau ferromanganese thiab silicon thermal ntau lawm ntawm cov hlau manganese.
Manganese thiab silicon yog lub ntsiab alloying ntsiab siv nyob rau hauv carbon steel. Manganese yog ib qho tseem ceeb deoxidizers hauv cov txheej txheem steelmaking. Yuav luag txhua hom hlau xav tau manganese rau deoxidation. Vim tias cov khoom siv oxygen tsim tawm thaum manganese siv rau deoxidation muaj cov ntsiab lus melting tsawg thiab yooj yim rau ntab; manganese kuj tseem tuaj yeem ua rau cov nyhuv deoxidation ntawm muaj zog deoxidizers xws li silicon thiab txhuas.
Txhua qhov kev lag luam steel yuav tsum tau ntxiv me me ntawm manganese ua desulfurizer kom cov hlau tuaj yeem kub dov, forged thiab lwm yam txheej txheem yam tsis muaj kev tawg. Manganese kuj tseem yog ib qho tseem ceeb ntawm cov hlau alloying hauv ntau hom hlau, thiab ntau dua 15% kuj ntxiv rau cov hlau alloy. ntawm manganese kom nce lub zog ntawm cov hlau. Silicon yog qhov tseem ceeb tshaj plaws alloying caij hauv npua hlau thiab carbon hlau tom qab manganese.
Hauv kev tsim cov hlau, silicon feem ntau yog siv los ua cov deoxidizer rau cov hlau molten los yog cov khoom siv hlau ntxiv kom muaj zog ntawm cov hlau thiab txhim kho nws cov khoom. Silicon kuj yog ib qho zoo pob zeb sib tsoo nruab nrab, uas tuaj yeem tig cov pa roj carbon monoxide rau hauv cov pob zeb sib tsoo dawb. Silicon tuaj yeem muab ntxiv rau cov qauv grey cam khwb cia hlau thiab cov hlau ductile txog li 4%. Ib tug loj npaum li cas ntawm manganese thiab silicon ntxiv rau molten hlau nyob rau hauv daim ntawv ntawm ferroalloys: ferromanganese, silicon-manganese thiab ferrosilicon.
