Silicon hlau 2202 feem ntau yog 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 qhov kawg castings. Los ntawm kev ntxiv cov hlau silicon, cov impurities no tau muab pov tseg, ua rau kom huv thiab zoo dua castings.
Nyob rau hauv cam khwb cia hlau foundries, silicon hlau 2202 txhawb kev tsim ntawm graphite thaum solidification. Cov graphite no tsim nyob rau hauv ib lub flake los yog nodular (spheroidal) qauv, nyob ntawm seb muaj pes tsawg leeg thiab cua txias. Lub xub ntiag ntawm graphite txhim kho cov khoom siv ntawm cov hlau cam, xws li lub zog, ductility, thiab thermal conductivity.
