Core hlau yog cov khoom sib xyaw. Nws yog tsim los ntawm crushing ntau yam additives (xws li deoxidizers, desulfurizers, alloys, thiab lwm yam) rau hauv ib tug tej yam particle loj thiab ces qhwv lawv nrog steel strips, nrog rau tej qhov ntev. Cov yam ntxwv ntawm cov tub ntxhais hlau muaj xws li: tag nrho cov ntaub ntawv tseem ceeb yog melted alloys, nrog rau ob peb inclusions, ruaj khov tshuaj tiv thaiv, siab nqus tus nqi, thiab muaj peev xwm ua tau zoo luv lub sij hawm smelting thiab precisely tswj cov muaj pes tsawg leeg. Cov tshuab no tau siv dav hauv cov tshuab steel niaj hnub thiab cov chaw tsim khoom.
