Cov hlau cored ua los ntawm kev sib xyaw calcium hlau nrog ib qho kev faib ua feem ntawm cov hmoov hlau yog hu ua calcium-hlau cored hlau.
Calcium-hlau cored hlau muaj 25-35% calcium hais, seem ntawm cov khoom sib xyaw ua ke ntawm cov hmoov hlau ua cov khoom tseem ceeb, cov sawb raws li daim tawv nqaij ua los ntawm cored hlau, cov lus qhia dav dav yog calcium 30 thiab calcium 40. ob hom. Kev lag luam hauv tsev thiab txawv teb chaws cov hlau thiab hlau tsis muaj cov pa roj carbon tsawg, cov pa roj carbon tsawg, cov hlau tsis muaj silicon thiab suav nrog cov duab, cov kev cai nruj ntawm cov hlau ntshiab calcium kev kho feem ntau yuav siv calcium thiab hlau core hlau.
Raws li steel refining deoxidiser, nws tsis tsuas yog txo cov clogging ntawm cov dej qhov hluav taws xob, tab sis ntxiv calcium rau cov hlau tiv thaiv kev tsim ntawm ntev streaks ntawm sulphide inclusions, yog li txhim kho cov anisotropy ntawm cov hlau. Nrog kev pab ntawm hlau feeder ceev input steel, yaj thiab yaj nyob rau hauv qhov tob ntawm steel, ua si lub luag hauj lwm ntawm deoxygenation, desulphurisation, de-inclusion, thiab nyob rau tib lub sij hawm yuav ua tau zoo-tuned muaj pes tsawg leeg, yuav ua rau cov hlau thiab tsis tshua muaj lub ntiaj teb. thiab lwm cov ntsiab lus los txhim kho tus nqi ntawm cov txiaj ntsig, los xyuas kom meej qhov ruaj khov ntawm cov muaj pes tsawg leeg. Txo cov nqi ntawm cov khoom tseem ceeb ntxiv, txo tus nqi ntawm kev ua kom zoo dua qub.
Φ13mm yog haum rau me me thiab nruab nrab-qhov cub hluav taws xob, Φ16mm yog haum rau cov hluav taws xob loj.
