Cored hlau yog cov cuab yeej metallurgical niaj hnub siv dav hauv cov hlau thiab cov chaw tsim khoom lag luam. Nws tso cai ntxiv cov ntsiab lus xws li calcium, magnesium, lossis silicon rau hauv cov hlau molten. Muab piv rau cov khoom siv ib txwm muaj, cov hlau cored txo cov khoom poob, txhim kho cov khoom rov qab, thiab ua kom cov txiaj ntsig zoo sib xws. Piv txwv li, ferro silicon magnesium cored hlau yog siv los tsim cov hlau hlau nrog zoo heev nodular graphite, thaum calcium silicon cored hlau txhim kho deoxidation thiab desulfurization efficiency. Kev siv cov cuab yeej siv cored hlau txo cov nqi tsim khoom thiab txhim kho cov khoom zoo.
