Hom cored hlau rau steelmaking
Tseeb tiag,cored kabplays lub luag haujlwm tseem ceeb hauv kev kos duab zoo nkauj ntawm steelmaking thiab yog siv rau ntau lub hom phiaj nrog rau deoxidation, desulphurization, alloying thiab refining.
Ntau hom cored hlau yog siv raws li cov kev cai tshwj xeeb.
Cov xov hlau no tau ntse tsim los qhia qee cov ntsiab lus rau hauv cov hlau molten, yog li txhim kho nws qhov zoo thiab kev ua tau zoo.
Calcium tub ntxhais hlau rau deoxygenation thiab desulfurization
Ib hom cored hlau siv nyob rau hauv steelmaking thiab metallurgy txheej txheem yog calcium cored hlau. Cov kab no tsuas yog siv rau deoxidation thiab desulfurization lub hom phiaj.
Los ntawm kev qhia calcium rau hauv cov hlau kub molten, cov hlau yuav pab tshem tawm cov impurities xws li oxygen thiab sulfur, yog li txhim kho tag nrho kev huv ntawm cov hlau.
Cov txheej txheem txhim kho cov khoom siv kho tshuab ntawm cov hlau thiab txo qhov kev pheej hmoo ntawm kev tsis xws luag, thiab lwm yam.
Fe-alloy cored hlau rau alloying thiab refining
Lwm yam tseem ceeb ntawm cored hlau nyob rau hauv steelmaking teb yog ferroalloy cored hlau. Cov hlau no yog siv rau lub hom phiaj noble ntawm alloying thiab refining cov muaj pes tsawg leeg ntawm hlau.
Hlau alloys xws li ferrochromium, ferromanganese thiab ferrosilicon yog encapsulated nyob rau hauv cov xov hlau, zoo li cov hniav nyiaj hniav kub zoo nkauj ntawm ib lub caj dab kub.
Thaum nkag mus rau qhov tob tob ntawm cov hlau yaj, cov hlau no ntxiv cov ntsiab lus tshwj xeeb los txhim kho cov hlau cov khoom, xws li corrosion kuj, lub zog thiab kub ua hauj. Tsis tas li ntawd, lawv pab tshem tawm impurities thiab tswj cov tshuaj muaj pes tsawg leeg ntawm cov hlau.
