Kev faib tawm ntawm ferrochromium

Chromium hlau muab faib ua cov pa roj carbon siab chromium hlau raws li cov ntsiab lus sib txawv, suav nrog kev them qib chromium hlau (C Tsawg dua lossis sib npaug li 10 feem pua), nruab nrab carbon chromium hlau (C Tsawg dua lossis sib npaug rau 4. {3}} feem pua), carbon chromium hlau tsawg (C Tsawg dua lossis sib npaug rau 0.5 feem pua), micro carbon chromium hlau (C Tsawg dua lossis sib npaug li 0.15%), thiab lwm yam. Silicon chromium alloy thiab nitrided ferrochrome kuj tseem siv tau. Chromium hlau feem ntau yog siv los ua cov khoom siv hlau ntxiv hauv steelmaking, thiab tau ntxiv rau tom qab theem ntawm steelmaking refining yav dhau los. Lub smelting ntawm tsawg-carbon hlau xws li stainless hlau yuav tsum tau siv tsawg thiab tsawg-carbon ferrochrome, uas ua rau ib tug loj-scale kev loj hlob ntawm refined ferrochrome ntau lawm. Vim yog kev txhim kho ntawm cov txheej txheem steelmaking, thaum tsim cov hlau tsis muaj steel thiab lwm qib steel siv AOD txoj kev (saib refining sab nraum lub cub tawg), carbon chromium hlau (feem ntau yog them qib chromium hlau) yog siv rau lub cub tawg, yog li tsuas yog qis thiab qis-carbon. chromium hlau yuav tsum tau muab ntxiv rau hauv cov theem tom ntej los kho qhov muaj pes tsawg leeg. Yog li ntawd, lub hom phiaj ntawm kev tsim cov chromium hlau yog los kho cov pa roj carbon chromium hlau.
