2202 silicon hlau feem ntau ntxiv rau cov hlau molten xws li cam khwb cia hlau thiab hlau ua deoxidizer. Thaum lub sij hawm melting txheej txheem, oxygen thiab lwm yam impurities tuaj yeem hnov mob nrog cov hlau, ua rau muaj qhov tsis xws luag hauv cov khoom tiav. Thaum nws yog xim hlau silicon ntxiv, cov impurities no raug tshem tawm, ua rau kom huv thiab zoo dua castings.
Hauv cov hlau casting, silicon 2202 txhawb kev tsim cov graphite thaum lub sij hawm solidification. Nyob ntawm seb muaj pes tsawg leeg thiab txias txias, graphite tsim ib qho scaly lossis nodular (spheroidal) qauv. Lub xub ntiag ntawm graphite txhim kho cov khoom siv ntawm cov hlau cam, xws li lub zog, ductility thiab thermal conductivity.
Peb cov hlau silicon yog ua tib zoo ntim rau hauv lub hnab yas tsis muaj dej tsis muaj dej, uas ua kom nws zoo thiab kev ncaj ncees thaum lub sijhawm thauj mus los. Txhua lub hnab muaj 1000kg ntawm hlau silicon, tab sis peb kuj tuaj yeem ua tau raws li koj qhov tshwj xeeb.
Ua tsaug rau peb txoj kev xa khoom zoo, koj tuaj yeem cia siab tias yuav tau txais koj daim ntawv xaj hauv 20 hnub tom qab ua koj cov nyiaj them ua ntej.
