Hlau smelting xav tau ntau cov ntaub ntawv raw, thiab txhua cov khoom siv raw yuav tsum tau txiav txim siab raws li cov kev cai, txwv tsis pub cov txiaj ntsig yuav cuam tshuam. Ib qho ntawm cov khoom siv raw yog silica. Dab tsi yog qhov yuav tsum tau ua rau qhov loj me ntawm silica hauv ferrosilicon smelting?
Yog hais tias qhov particle loj dhau lawm, cov tshuaj tiv thaiv ceev yuav qeeb. Yog hais tias qhov loj me me dhau los yog muaj cov hmoov ntau dhau lawm, huab cua permeability ntawm cov khoom nto yuav raug cuam tshuam. Silica nrog ntau cov hmoov kuj tau coj mus rau hauv cov av, nce tus nqi ntawm slag. Daim ntawv pov thawj ntau lawm: silica siv nyob rau hauv lub qhov cub kub ntawm cov siliceous hlau ore yuav tsum muaj ib tug particle loj ntawm 60 ~ 120mm, ntawm cov particle loj tshaj 80mm yog ntau tshaj 50 feem pua. Me me ferrosilicon rauv yuav tsum tau silica particle loj ntawm 25 ~ 80mm, ntawm uas 50 feem pua yog ntau tshaj 40mm.
