Raws li ib tug ua silicon hlau chaw tsim tshuaj paus, tsis tsuas yog peb tsim thiab muab ib tug ua tiav ntau yam ntawm silicon hlau cov khoom, tab sis peb kuj muaj kev nkag siab tob txog ntau yam ntawm silicon hlau cov ntaub ntawv. Cov neeg uas muaj kev nkag siab ntawm silicon hlau paub tias silicon carbide tuaj yeem muab faib ua ntau hom, txhua tus muaj cov haujlwm sib txawv thiab kev siv hauv kev lag luam sib txawv. Txhawm rau txhim kho kev nkag siab ntawm silicon hlau, silicon hlau manufacturers tau sib sau ua ke lawv cov kev paub dav dav ntawm silicon hlau thiab piav qhia nws daim ntawv thov hauv kev lag luam steel.
Cov ntaub ntawv tseem ceeb rau kev tsim cov hlau silicon yog silica xuab zeb, coke coke thiab ntoo chips, thiab ob yam khoom siv kawg yog cov khoom siv carbon. Los ntawm kev kho qhov feem pua ntawm cov khoom siv raw hauv cov txheej txheem tsim khoom, peb tuaj yeem xyuas kom meej tias cov khoom zoo tshaj plaws ntawm silicon hlau tau txais. Kev tsim cov hlau silicon yog cov txheej txheem tshuaj lom neeg uas txhua feem cuam tshuam nrog rau lwm tus. Yog hais tias qhov kev faib ua feem ntawm ib yam khoom yog siab dhau los yog tsawg dhau, cov tshuaj tiv thaiv yuav tsis ua haujlwm zoo. Txhawm rau kom ua tiav qhov zoo tshaj plaws ntawm silicon hlau, silica xuab zeb yuav tsum tau ua hauv av rau qhov yuav tsum tau ua. Nyob rau hauv tus txheej txheem ntawm kev sib tsoo cov silica xuab zeb, impurities uas muaj kuj tsawg npaum li cas ntawm silicon yuav tsum tau muab tshem tawm. Kev sib xyaw ua ke ntawm hlau silicon thiab oxygen yog ruaj khov dua li kev sib xyaw ntawm cov hlau. Thaum lub sij hawm welding, qhov tsim ntawm tsawg melting point silicate los ntawm silicon tsub kom lub fluidity ntawm slag thiab molten hlau, ua rau spattering thiab impairing weld zoo. Silicon yog ib qho zoo deoxidizer. Thaum txhuas siv rau deoxidation, qhov sib ntxiv ntawm ib qho nyiaj ntawm silicon tuaj yeem ua rau muaj qhov deoxidation ntau ntxiv. Silicon tawm qee qhov seem ntawm cov hlau, uas tuaj yeem ua cov khoom siv hlau smelting thiab steel ua.
