Yog li, silicon thiab calcium tseem ceeb heev thaum nws los ua hlau. Lawv pab tshem tawm cov pa oxygen thiab sulfur, uas qee zaum tuaj yeem nkag mus rau hauv txoj kev thaum koj ua hlau. Lawv ob leeg zoo heev ntawm kev ua kom oxygen thiab sulfur, yog li lawv tuaj yeem siv los ntxuav cov hlau. Thiab qhov txias tshaj plaws yog, lawv tsis yog ntxuav nws xwb, lawv kuj ua rau cov hlau muaj zog dua. Deoxidation thiab desulfurization
Hauv cov txheej txheem steelmaking, oxygen thiab sulfur yog xov xwm phem vim lawv cuam tshuam rau cov hlau zoo. Thaum silicon thiab calcium ntxiv rau molten steel, nws reacts nrog oxygen los tsim oxides uas ntab mus rau saum npoo thiab yooj yim tshem tawm. Calcium kuj reacts nrog sulfur los tsim calcium sulfide, uas kuj raug tshem tawm ntawm cov hlau molten. Qhov no muab rau koj high-purity steel, uas yog ib qho tseem ceeb heev rau daim ntaub ntawv uas koj xav tau cov khoom zoo heev.
Raws li kev ntxuav steel, silicon kuj cuam tshuam rau nws cov khoom. Nws hloov cov muaj pes tsawg leeg ntawm cov hlau tsis muaj hlau, ua kom cov ductility, tensile zog, thiab toughness. Qhov no ua rau cov hlau zoo dua rau cov ntawv tshwj xeeb xws li kev tsim kho tsheb ciav hlau, tsheb qhov chaw, thiab cov ntawv thov siab xws li txuas hniav thiab cov tsev siab.3. Hloov Aluminium Aluminum feem ntau yog siv rau deoxidation thaum ua hlau, tab sis silicon-calcium hmoov yog lwm txoj hauv kev zoo. Siv silicon-calcium hmoov es tsis txhob txhuas muaj ib pawg ntawm qhov zoo. Piv txwv li, nws nres alumina los ntawm clogging thaum lub sij hawm casting thiab ua rau cov hlau zoo tag nrho. Qhov no ua rau cov txheej txheem ntau lawm smoother, txo cov teeb meem thaum lub sijhawm ua haujlwm, thiab txhim kho qhov zoo ntawm cov khoom kawg.
Silicon-calcium hmoov kuj tseem ceeb heev hauv kev tsim cov hlau cam khwb cia. Nws yog siv los ua cov kab lis kev cai pib, uas pab tsim cov graphite, ua rau cov hlau cam khwb cia zoo dua qub thiab muaj zog dua. Nws kuj pab tshem tawm cov sulfur, uas ua rau cov hlau cam khwb cia zoo tuaj yeem tiv taus hnav thiab tsim kua muag.
