Calcium-silicon cored hlau yog tsim los ntawm cov khoom siv hlau xws li silicon thiab calcium, nrog rau cov khoom siv txheej, thiab yog cov khoom tseem ceeb hauv cov hlau smelting. Nws yog tsim los ntawm encasing ib tug calcium - silicon alloy nyob rau hauv ib tug hlau los yog txhuas sawb siv ib tug tshwj xeeb txheej txheem los tsim ib tug tub ntxhais hlau qauv.
Calcium-silicon hlau thiab calcium-silicon alloy zoo li cov noodles thiab hmoov nplej- qub yog cov khoom tiav tiav, thaum tom kawg yog cov khoom siv raw. Calcium-silicon hlau yog cov khoom siv sib xyaw ua ke ua los ntawm encasing calcium-silicon alloy hmoov nyob rau hauv cov hlau sheath; nws txoj kab uas hla feem ntau yog 5-13 hli, thiab nws hloov tau zoo li cov hlau cable. Calcium-silicon alloy, ntawm qhov tod tes, yog ib qho blocky lossis granular intermediate hlau alloy nrog silvery-grey metallic luster hauv ntu ntu; nws nyuaj tab sis nkig.
