Tus nqi ntawm ib tuj ntawm cov khoom ramming rau cov hlau ua kom sov li cas? Feem ntau, cov cua kub yaj hlau yog me dua cov hluav taws xob hluav taws xob, thiab feem ntau yog siv los tsim cov castings thiab qee qhov kev txiav txim siab raug. Xyoo tsis ntev los no, nws kuj tseem tau siv los ua kom cov hlau tsis huv. Nws cov khoom siv hluav taws xob yog qhov yooj yim. Feem ntau, cov khoom siv hlau melting rauv ramming tau siv. Cov khoom siv hlau ua kom sov rau yaj cov hlau feem ntau siv quartz acidic ramming cov ntaub ntawv. Thaum forging hlau rau qee qhov tseeb castings hauv induction cua sov, aluminium-magnesium thiab corundum cov ntaub ntawv qhuav tau siv ntau, thiab cov khoom siv aluminium-silicon ramming kuj tseem siv. Kuj tseem muaj qee qhov npaj txhij ua crucibles rau qhov cub tawg. Thaum tsis yog cov khoom siv sib nqus yuav tsum tau yaj, cov khoom siv graphite crucibles yuav raug siv.
