Cov thev naus laus zis cored yog ib txoj kev tawm tshiab ntawm kev ua kom sov sab nraum zoov, uas yog siv dav hauv cov hlau pub khoom siv niaj hnub steelmaking. Alloy cored hlau tuaj yeem ua kom huv si molten steel, hloov cov morphology ntawm kev suav, txhim kho castability thiab mechanical zog ntawm molten steel, ua rau kom cov yields ntawm alloys, txo cov nqi steelmaking, thiab muaj txiaj ntsim kev lag luam.
Cored hlau yog cov khoom sib xyaw uas rhuav tshem ntau yam khoom ntxiv (deoxidizers, desulfurizers, modifiers, alloys, thiab lwm yam) uas yog npaj los ntxiv rau cov hlau molten lossis hlau rau hauv qee qhov me me, thiab tom qab ntawd suav nrog cov khoom sib xyaw ntawm txhua qhov ntev. siv txias dov low-carbon steel strips.
Nws yog ua los ntawm alloy hmoov qhwv nyob rau hauv ib daim hlab zoo li tus steel strips. Raws li cov hmoov txhuas sib txawv, lawv tuaj yeem muab faib ua: silicon calcium cored hlau, silicon manganese calcium hlau, silicon calcium barium hlau, barium aluminium hlau, aluminium calcium hlau, calcium hlau hlau, calcium hlau ntshiab, thiab lwm yam. Cov tsos ntawm winding yog zoo ib yam li cov kauj. Sib txawv ntawm cored hlau siv hauv kev lag luam textile.
Dab tsi yog cov yam ntxwv ntawm cored hlau?
1. Nws yog qhov tsim nyog rau kev kho thiab tswj cov ntsiab lus ntawm cov ntsiab lus yooj yim oxidizable thiab kab kawm, txhim kho cov txiaj ntsig ntawm alloy, txo cov nqi ntawm kev tawm dag zog, ua kom lub sijhawm ua haujlwm luv, thiab tswj cov khoom kom raug.
2. Txhawm rau ua tiav cov txiaj ntsig ntawm cov kua dej ntshiab huv thiab qee qhov kev hloov kho rau cov khoom thiab cov duab ntawm impurities, txhim kho cov kua steel zoo thiab txhim kho cov txheej txheem casting.
3. Lub cored hlau yuav muab faib ua ob hom: ib txwm aspirated thiab externally aspirated. Cov cuab yeej siv tshuab xav tau rau kev pub hlau yog qhov yooj yim thiab txhim khu kev qha, nrog rau me me hneev taw. Tshwj xeeb tshaj yog, cov xov hlau sab hauv aspirated cored yog qhov tsim nyog rau kev siv hauv zos hauv cheeb tsam nqaim.
