Metallurgical cored hlau siv steel sawb raws li nws lub plhaub sab nrauv, ntim nrog cov khoom siv hmoov xws li silicon -calcium thiab ferroalloys, thiab muaj ib lub voj voog lossis duab plaub -section.
Nyob rau hauv cov txheej txheem steelmaking, cored hlau yog txhaj ntawm kev kub ceev mus rau hauv qhov sib sib zog nqus ntawm cov hlau molten los ntawm ib tug hlau feeder, ua tiav cov haujlwm hauv qab no: Precisely tswj tus nqi ntawm alloying ntsiab ntxiv, txhim kho tus nqi siv deoxidizers xws li txhuas thiab calcium, thiab txo cov cua nqus hauv cov hlau molten.
Nws hloov kho uas tsis yog -hlau suav nrog, txhim kho cov dej ntws ntawm cov hlau molten, thiab tiv thaiv nozzle thaiv thaum lub sij hawm nruam nruam.
