Silicon carbide yog ib hom tshiab ntawm cov muaj zog sib xyaw deoxidizer. Nws yog qhov sib txawv ntawm cov tshuaj deoxidizers uas nws muaj cov nyhuv deoxidation zoo, ua kom lub sijhawm deoxidation luv, cov ntaub ntawv slagging thaum ntxov, muaj qhov tuab txo qhov cua, txuag lub zog, txhim kho steelmaking efficiency thiab txhim kho zoo. Silicon carbide muaj kev ruaj ntseg zoo, zoo oxidation tsis kam thiab thermal poob siab, thiab tau siv dav.
Refractory cov ntaub ntawv thiab cov ntaub ntawv corrosion-resistant: Vim hais tias silicon carbide muaj lub siab melting point (degree ntawm decomposition), tshuaj inertness thiab tsis kam mus thermal shock, silicon carbide yuav siv tau nyob rau hauv cov cuab yeej abrasive, sheds thiab saggers siv nyob rau hauv ceramic khoom firing kilns, Silicon carbide ceramic khoom xws li silicon carbide cib, aluminium electrolytic cell linings, crucibles, me me rauv cov ntaub ntawv thiab lwm yam khoom siv nyob rau hauv ntsug cylinder distillation furnaces nyob rau hauv zinc smelting kev lag luam.
Kev siv tshuaj lom neeg: Silicon carbide tuaj yeem siv los ua purifier rau smelting steel, uas yog, raws li deoxidizer rau steelmaking thiab cov qauv txhim kho rau cam khwb cia hlau. Qhov no feem ntau siv tsawg purity silicon carbide los txo cov nqi. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tsim silicon tetrachloride.
Kev siv hluav taws xob: siv los ua cov khoom cua sov, cov ntsiab lus tsis-linear tsis kam thiab cov khoom siv hluav taws xob siab. Cov khoom siv cua sov xws li silicon carbon rods (tsim rau ntau lub tshuab hluav taws xob ua haujlwm ntawm 1100 txog 1500 degree, nonlinear resistor ntsiab, thiab ntau yam hluav taws xob tiv thaiv li qub.
Tus nqi ntawm npua hlau nyob rau hauv tus nqi yuav tsum tau tswj. Silicon carbide manufacturers pom zoo tias nws nyob ib ncig ntawm 10%. Qhov tsim nyog feem ntawm smelting silicon carbide raws li tus nqi ntxiv yog nyob nruab nrab ntawm 40% thiab 55%. Thaum lub sij hawm tapping txheej txheem, cov khoom tsim nyog silicon carbide yuav tsum raug xaiv, thiab cov nyiaj ntxiv yuav tsum yog 0.1%-0.2% ntau dua thaum lub sij hawm cupola melting. Yog tias koj muaj lus nug lossis xav tau ntawm silicon carbide, koj tuaj yeem hu rau peb rau kev sab laj txhua lub sijhawm.
