Silicon calcium cored hlau yog ib hom silicon calcium cored hlau hauv steel smelting. Daim ntawv thov ntawm hom cored hlau no tuaj yeem zam tsis ntxiv lwm yam impurities thaum pub mis. Nyob rau tib lub sijhawm, silicon calcium cov ntsiab lus nyob rau hauv no silicon calcium hlau yog ntau dua, uas tuaj yeem hnov mob nrog oxygen thiab lwm yam teeb meem hauv cov kua hlau thaum siv, kom tshem tawm nws.
Hlau pub tshuab tuaj yeem ua tau zoo tso silicon calcium hlau rau hauv txoj haujlwm zoo tshaj plaws hauv cov hlau molten, hloov cov morphology ntawm kev suav, thiab txhim kho cov castability thiab txhua yam khoom ntawm molten steel. Cov tshuaj tiv thaiv ntawm silicon calcium hlau thiab molten hlau yog khaus ntau dua li ntawm silicon calcium hlau. Kev saib xyuas yuav tsum tau them rau cov haujlwm kho calcium, xws li kev pub mis tob thiab xaim ceev ceev. Thaum lub sij hawm xaim pub mis, vim qhov loj calcium vapor siab ntawm cov khoom ntshiab calcium hlau, txhawm rau tiv thaiv lub ntuj evaporation ntawm calcium, cov khoom ntshiab calcium hlau yuav tsum tau pub tob heev. Ib txoj hauv kev yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, nws yog qhov yuav tsum tau ua kom lub thickness ntawm cov hlau hlau los tiv thaiv nws cov melting ntxov ntxov los ntawm kev cuam tshuam cov calcium tso tawm qhov tob. Hlau pub ceev thiab xaim noj atherosclerosis yog qhov tseem ceeb ntawm silicon calcium hlau noj cov txheej txheem, Kev ceev ceev los yog qeeb heev hlau pub ceev thiab atherosclerosis yuav cuam tshuam rau lub sij hawm melting thiab oxidation degree ntawm silicon calcium hlau, uas ua rau cov nyhuv metallurgical. Yog li ntawd, thaum thov silicon calcium hlau, peb yuav tsum nco ntsoov xyuam xim rau qhov xwm txheej ntawm molten hlau. Qhov tseeb, ntau hom additives yuav muab ntxiv rau hauv steel smelting, thiab cov teebmeem ntawm cov additives sib txawv. Silicon calcium hlau yog ib qho khoom siv feem ntau siv hauv steelmaking. Qhov sib ntxiv thiab daim ntawv thov txoj kev kuj txawv ntawm lwm yam additives. Tsuas yog raws li qhov tseeb ferroalloy ntxiv txoj kev, tuaj yeem ua silicon calcium hlau ua lub luag haujlwm zoo dua. Yog li ntawd, tus neeg teb xov tooj yuav tsum tau xyuam xim rau cov hlau molten. Thaum cov hlau molten dov hnyav, tus neeg teb xov tooj yuav tsum nres ib pliag ua ntej txuas ntxiv pub cov hlau kom tiv thaiv kev txaws.
