Ntxim ntawm slag rau siab carbon chromium hlau ntxuav hlau smelting
Cov pa roj carbon ntau ferrochrome tuam txab hauv cov txheej txheem ntawm cov pa roj carbon ntau ferrochrome dej hlau txheej txheem, yuav siv cov slag, hauv qab no Shanghai siab tshaj plaws carbon ferrochrome cov neeg xa khoom los piav qhia txog lub luag haujlwm ntawm slag hauv kev nthuav dav.
Hauv hluav taws xob ua kom sov smelting (hluav taws xob arc rauv, ntxhia cua sov ua kom sov, electroslag remelting rauv, thiab lwm yam) slag ua lub luag haujlwm ntawm kev tiv thaiv cua sov ua haujlwm. Slag ua lub luag haujlwm uas txiav txim siab los ua kom cov khoom zoo ntawm cov khoom sib tsoo, tus nqi rov qab hlau, kev ua haujlwm du rau kev ua haujlwm thiab ntau yam ntsuas kev ua haujlwm thiab kev lag luam.
Kev tsim cov tshuaj tseem ceeb hlau oxides.
Tshem tawm cov teeb meem tsis zoo xws li leej faj, phosphorus thiab oxygen hauv molten steel, nqus cov hlau tsis muaj hlau ua rau cov hlau tsis huv, thiab tiv thaiv molten steel los ntawm kev nqus ncaj qha hydrogen, nitrogen thiab oxygen.
Sib sau molten slag ua rau gangue Cheebtsam lossis impurity oxidation khoom thiab molten hlau los yog matte du sib cais.
Ib qho ntxiv, nws yuav tsum raug sau tseg tias lub slag kom ua tiav cov xim hlau ua tau zoo lossis phem, feem ntau txiav txim siab los ntawm lub ntsiab lus melting ntawm molten slag, viscosity, thaj tsam (nto) saum npoo tsis sib haum, kev sib tsoo tshwj xeeb, hluav taws xob conductivity, enthalpy, thermal conductivity thiab qee feem ntawm kev ua (A). Cov yam ntxwv ntawm lub cev thiab tshuaj yog txiav txim siab los ntawm cov sib xyaw hauv cov slag. Cov sib xyaw ua ke ntawm slag tau muab kho los ntawm kev ntxiv qhov tsim nyog ntawm flux, qhov tseem ceeb tshaj plaws flux yog limestone thiab quartz pob zeb. Cov tshuaj fluorite (CaF2) tseem yog qhov tseem ceeb ntawm kev siv hluav taws xob ua hluav taws xob slag thiab hluavtaws slag hauv hluav taws xob cua sov.
