Khoom Description
Hauv cov txheej txheem steelmaking niaj hnub,alloy cored hlaumaj mam dhau los ua qhov tseem ceeb thiab tseem ceeb.
Alloy cored hlau, raws li cov khoom siv tshwj xeeb tshwj xeeb siv rau steelmaking, nws lub luag haujlwm tseem ceeb yog ua kom huv huv cov morphology ntawm steel inclusions. Cov yam ntxwv no yog qhov tseem ceeb rau kev txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau.
Yuav kom nkag siab tob txog nws, ib tus yuav tsum xub nkag siab txog nws cov ntsiab lus. Tub ntxhais hlau tsis yog ib yam khoom siv yooj yim, tab sis ua tib zoo tsim cov khoom sib xyaw. Nws yog cov txheej txheem ntawm crushing ntau yam additives uas yuav tsum tau ntxiv rau molten steel los yog hlau, xws li deoxidizers, desulfurizers, modifiers, alloys, thiab lwm yam., rau hauv ib tug tej yam particle loj. Cov additives no tau ua tib zoo xaiv thiab ua tiav los xyuas kom meej tias lawv qhov kev ua tau zoo hauv cov txheej txheem steelmaking.
Lub luag haujlwm ntawm alloy cored hlau
Nyob rau hauv cov txheej txheem steelmaking, thaum lub alloy tub ntxhais hlau yog nkag mus rau hauv cov kua steel, cov additives nyob rau hauv nws muaj peev xwm sai sai react nrog impurities thiab teeb meem nyob rau hauv lub steel kua. Deoxidizers tuaj yeem tshem tawm cov pa oxygen ntawm cov hlau thiab txo qhov tsim ntawm oxide inclusions; Desulfurizers tuaj yeem txo cov sulfur cov ntsiab lus hauv cov hlau, txhim kho nws cov tawv nqaij thiab ductility; Cov neeg ua haujlwm metamorphic tuaj yeem hloov cov qauv siv lead ua ntawm cov hlau thiab txhim kho nws cov khoom siv kho tshuab; Qhov sib ntxiv ntawm cov ntsiab lus alloying tuaj yeem kho cov tshuaj muaj pes tsawg leeg ntawm cov hlau kom tau raws li kev siv sib txawv.
Hauv cov txheej txheem steelmaking, lub sijhawm qhia ntawm cov tub ntxhais hlau yuav tsum tau txiav txim siab raws li cov txheej txheem steelmaking tshwj xeeb thiab cov hom phiaj, thiab nws feem ntau raug xaiv kom raug ntxiv rau cov kua hlau steel ntawm theem tsim nyog.
Feem ntau hais lus, nws yog qhia thaum lub sij hawm steel refining los yog tej theem ua. Nyob rau theem no, qhov kub thiab muaj pes tsawg leeg ntawm cov kua steel tau mus txog qee yam kev mob, uas tuaj yeem pab txhawb cov tshuaj tiv thaiv txaus ntawm cov khoom ntxiv hauv cov tub ntxhais hlau thiab cov kua hlau steel, txhawm rau ua kom tiav deoxidation, desulfurization, hloov cov khoom ntawm kev suav, thiab zoo kho qhov muaj pes tsawg leeg.
