Kev soj ntsuam ntawm qhov zoo ntawm Ferrosilicon 75 Raws li Raw Material Analysis
Silica ua haujlwm tseem ceeb hauv kev tsim cov ferrosilicon 75, yog li tsim kom muaj kev sib raug zoo ntawm ferrosilicon 75 thiab qhov zoo ntawm silica siv. Kev ntsuam xyuas ntawm silica zoo yog kwv yees ntawm cov qauv tshwj xeeb, tshwj xeeb tshaj yog tias cov ntsiab lus silica yuav tsum tshaj 97%. Tsis tas li ntawd, thaum lub sij hawm smelting txheej txheem ntawm silica, txhuas trioxide yog nquag generated. Qhov sib xyaw no tsis tsuas yog cuam tshuam cov slag emissions thaum lub sij hawm steel smelting tab sis kuj elevates cov txhuas cov ntsiab lus nyob rau hauv ferrosilicon, uas considerably deteriorates tag nrho cov zoo ntawm cov khoom ferrosilicon.
Kev sib xyaw ntawm Calcium Oxide thiab Magnesium Oxide cuam tshuam qhov zoo ntawm Ferrosilicon 75.
Cov ntsiab lus ntawm calcium oxide thiab magnesium oxide hauv ferrosilicon yuav tsum tsis pub tshaj 1%. Yog hais tias qhov concentration tshaj qhov pib no, qhov ntau ntawm smelting slag generated thaum lub sij hawm steelmaking nce, ua rau corrosion ntawm cov pa hlau, uas considerably deteriorates qhov zoo ntawm ferrosilicon 75.
Qhov loj me me ntawm silica yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm ferrosilicon 75.
Qhov loj me me ntawm silica ho cuam tshuam qhov zoo ntawm ferrosilicon 75. Ib qho loj heev silica particle loj tuaj yeem cuam tshuam cov tshuaj tiv thaiv tus nqi thaum lub sij hawm melting txheej txheem, thaum lub sij hawm me me particle loj tuaj yeem ua rau muaj cov hmoov ntau ntxiv, cuam tshuam rau qhov permeability ntawm qhov chaw. ferrosilicon 75. Yog li ntawd, nws yog ib qho tseem ceeb los txiav txim siab qhov loj me me. Rau kev tsim cov ferrosilicon 75, qhov pom zoo silica particle loj yog li ntawm 60 mus rau 120 hli, nrog ntau tshaj 50% ntawm cov khoom ntau tshaj 80 hli. Nyob rau hauv sib piv, me me ferrosilicon furnaces yuav tsum tau ib tug silica particle loj ntawm 25 mus rau 80 mm, nrog tsawg kawg yog 50% ntawm cov hais loj tshaj 40 hli.
