Basic Knowledge ntawm Silicon Manganese Alloy

Manganese thiab silicon yog lub ntsiab alloying ntsiab siv nyob rau hauv carbon steel. Manganese yog ib qho tseem ceeb tshaj plaws Oxygen scavenger nyob rau hauv cov txheej txheem ntawm steelmaking. Yuav luag txhua qib steel yuav tsum tau deoxidized nrog manganese. Vim tias cov khoom siv oxygen tsim thaum siv manganese rau deoxidation muaj qhov qis melting thiab yooj yim rau ntab; Manganese kuj tseem tuaj yeem ua rau cov nyhuv deoxidation ntawm muaj zog Oxygen scavenger xws li silicon thiab txhuas. Tag nrho cov hlau muaj hlau yuav tsum tau ntxiv ib qho me me ntawm manganese ua desulfurizer los pab kom kub dov, forging, thiab lwm yam txheej txheem yam tsis muaj pob txha. Manganese kuj yog qhov tseem ceeb tshaj plaws alloying ntsiab nyob rau hauv ntau qib steel, thiab ntau tshaj 15 feem pua ​​manganese kuj ntxiv rau hlau alloy kom nws cov qauv muaj zog. Silicon yog qhov tseem ceeb tshaj plaws alloying keeb nyob rau hauv npua hlau thiab carbon hlau, thib ob tsuas yog manganese. Hauv kev tsim cov hlau, silicon feem ntau yog siv los ua Oxygen scavenger rau cov hlau molten, lossis ua cov khoom siv hlau ntxiv kom muaj zog thiab txhim kho kev ua haujlwm ntawm cov hlau. Silicon kuj yog qhov nruab nrab graphitization zoo, uas tuaj yeem hloov cov pa roj carbon monoxide rau hauv cov graphite carbon dawb. Cov ntsiab lus silicon nyob rau hauv tus qauv Grey hlau thiab nodular cam khwb cia hlau tuaj yeem ncav cuag 4 feem pua. Ib tug loj npaum li cas ntawm manganese thiab silicon yog ntxiv rau molten hlau nyob rau hauv daim ntawv ntawm ferroalloys: manganese hlau, silicon manganese, thiab silicon hlau.
Cov khoom siv raw rau kev tsim manganese silicon alloy muaj xws li manganese ore, manganese nplua nuj slag, silica, coke, dolomite (los yog limestone), thiab fluorite. Kev tsim cov manganese silicon alloy tuaj yeem siv ib hom manganese ore los yog sib tov ntawm ob peb manganese ores (xws li manganese nplua nuj slag). Raws li qhov yuav tsum tau ua kom cov manganese silicon alloy muaj cov ntsiab lus ntawm cov hlau thiab phosphorus qis dua li cov pa roj carbon manganese hlau, manganese ore rau smelting manganese silicon alloy yuav tsum muaj ntau dua manganese hlau piv thiab manganese phosphorus piv. Qhov siab dua cov ntsiab lus ntawm manganese ntawm manganese ore siv, qhov zoo dua ntawm ntau yam ntsuas.
