Steel slag yog pov tseg residue uas ua rau kev lag luam hlau. Nws cov nqi ntau yog 8% ~ 15% ntawm cov zis ntawm cov khoom siv nyhav. Cov hlau cag zis muaj zog zuj zus nrog txoj kev lag luam hlau, yog li ntawd, cov khoom siv thiab kev siv cov khib nyiab khib nyiab raug them ntau dua.
Feem ntau, cov ntaub qhwv steel yog crushed coarsely cais loj steel slag, thiab ces los ntawm nruab nrab thiab nplua crushing.
Luoyang Yujie tsim cov txheej txheem qhuav thiab ntub cov txheej txheem rau steel slag rov qab xav. Tsis muaj dej yuav tsum muaj nyob rau hauv cov txheej txheem cov hlau qhuav qhwv qhuav, qhov slag yuav crushed, milled thiab cov khoom sib nqus thiab ces hloov hauv qib A lossis B cov hlau khib nyiab, cov ntsiab lus hlau yuav tshaj 55% thiab cov ntsiab lus ntawm hlau nplaum hauv 5- 10 hli tailing slag yog 2% hauv qab. Cov khoom yuav siv tau rau hauv cov cement lossis steel zoo hmoov tom qab tso npe. Txais tos hnub nyoog thiab tus neeg muas zaub hu rau peb.
