Ob Txoj Kev Smelting Rau Silicon Carbide

Thawj yog cov khoom siv tshiab: txoj kev siv cov khoom tshiab tso cov ntaub ntawv tshiab (silica xuab zeb, roj av coke) ncaj qha mus rau thaj tsam ntawm qhov cub rau smelting. Cov khoom siv tshiab muaj qhov hloov pauv me me hauv cov xim zoo, thiab cov qauv ntawm cov khoom siv rau hauv qhov cub yog qhov ruaj khov, yog li qhov zoo ntawm cov khoom kuj tseem ruaj khov.
Qhov thib ob yog txoj kev roasting khoom: cov khoom tshiab yog thawj zaug loaded rau hauv qab thiab rwb thaiv tsev cheeb tsam ntawm ob sab ntawm lub cub tawg rau roasting, thiab cov khoom roasting tau smelted nyob rau hauv cov tshuaj tiv thaiv cheeb tsam ntawm lub cub tawg tom ntej no. Muaj ob hom roasting khoom txoj kev. Ib txoj hauv kev tsuas yog thauj cov ntaub ntawv tshiab rau hauv qab ntawm lub qhov cub rau roasting, uas yog hu ua qhov cub hauv qab roasting txoj kev. Lwm qhov yog thauj cov ntaub ntawv tshiab rau hauv qab ntawm lub qhov cub thiab ci ob sab tib lub sijhawm, uas yog hu ua tag nrho roasting txoj kev. Txoj kev siv cov khoom siv roasting siv qhov kub hauv qhov cub kom tshem tawm cov teeb meem tsis zoo hauv cov khoom tshiab hauv thaj chaw roasting khoom. Nws yog cov polymerization ntawm silica xuab zeb thiab roj av coke rau hauv cov khoom ntxeem tau nrog huab cua permeability zoo. Cov khoom siv hluav taws xob ntsuab roasting kuj muaj qee cov ntsev uas diffuses los ntawm cov khoom siv tshuaj tiv thaiv. Kev siv cov khoom ci ci rov qab rau hauv lub qhov cub tuaj yeem ua rau cov khoom siv hluav taws xob nce ntxiv, txo cov khoom siv hluav taws xob hauv ib chav tsev, thiab tuaj yeem siv tsawg dua los yog tsis muaj ntoo chips. Thaum siv rau hauv qhov cub ntsuab los npaj cov khoom siv tshuaj tiv thaiv, cov ntsev tsawg tuaj yeem ntxiv dua li cov khoom siv raw.
