Cov txheej txheem steelmaking hauv qab no yog qhov haum rau kev sivcalcium silicon cored hlau:
Converter steelmaking
Siv cov hlau molten rau cov khoom siv rawing, cov pa roj ntsha thiab cov impredy oxygen los muab cov tshuaj tiv thaiv me me, nrog kev ua haujlwm siab thiab cov nqi qis.
Tom qab tom qab kho cov theem hloov pauv, tshwj xeeb tshaj yog thaum deoxidizing, desulfizing thiab fine-rading hlau cored hlau tuaj yeem ua lub luag haujlwm zoo. Cov calcium silicon cored hlau tuaj yeem ntxiv ntxiv rau cov stadle ntawm cov hlau pub dawb, txhim kho qhov ua tau zoo ntawm cov hlau los ua kev ua tau zoo ntawm cov hlau ntxiv nrog cov cai.
Hluav Taws Xob Hluav Taws Xob
Siv cov qauv steel raws li cov khoom siv rawically tseem ceeb los ntawm hluav taws xob cov khoom siv kub thiab smelting huab cua, thiab muaj qhov zoo hauv kev tsim cov qib tshwj xeeb.
Thaum lub sijhawm txo qis lossis rov ua kom lub sijhawm hluav taws xob hluav taws xob fais fab, ntxiv calcium silicon cored hlau muaj peev xwm zoodeoxidizethiabDesulfurize, tshem tawm cov teeb meem impurities nyob rau hauv steel, thiab txhim kho lub purity ntawm hlau. Rau zus tau cov khoom siv hlau Highoy, precision alloy thiab lwm yam hlau, calcium silicon cored xov tooj, xws li kev txhim kho cov tawv thiab hnav tsis kam ntawm cov hlau.
Tawm-ntawm-cua sov rauv ua cov txheej txheem
Lub Molten hlau uas tau pib ua kom zoo nyob rau hauv cov thawv steelmaking, thiab lwm yam, tshem tawm cov khoom siv hauv tsev, thiab lwm yam.
Calcium sited hlau cored hlau yog ib qho ntawm cov khoom siv feem ntau hauv cov cua sov rauv. Thaum lub sij hawm pw ua kom zoo nkauj, los ntawm kev pub tshuaj calcium Coredon Cored hlau, kev sib txuas ntawm cov hlau thiab cov khoom siv ua kom tau zoo ntawm Moltening ntawm Molten cov khoom ntawm cov hlau tuaj yeem hloov kho. Piv txwv li, thaum tsim cov hlau tshwj xeeb xws li cov hlau tsis muaj zog, thiab txhim kho cov hlau muaj zog, thiab txhim kho cov hlau corrosion, thiab kub siab tsis kam thiab lwm yam khoom.
