Cov hmoov graphite muaj ntau yam kev siv, xws li cov khoom siv pwm thiab cov khoom siv refractory ua los ntawm cov hmoov graphite thiab cov khoom lag luam cuam tshuam, xws li crucibles, flask, stoppers thiab nozzles. Cov hmoov graphite muaj kev tiv thaiv hluav taws, kev nthuav dav thermal qis, kev ruaj khov thaum nws nkag mus thiab ntxuav los ntawm hlau hauv cov txheej txheem ntawm kev yaj hlau, kev ruaj khov thermal shock zoo thiab kev ua tau zoo thermal conductivity ntawm qhov kub siab, yog li cov hmoov graphite thiab nws cov khoom lag luam cuam tshuam tau siv dav hauv cov txheej txheem ntawm kev yaj hlau ncaj qha. Tus kws kho graphite Furuite hauv qab no yuav qhia koj kom meej:
Cov av nplaum graphite ib txwm muaj yog ua los ntawm cov flake graphite uas muaj ntau dua 85% carbon, feem ntau cov graphite flake yuav tsum loj dua 100 mesh. Tam sim no, qhov kev txhim kho tseem ceeb hauv kev siv tshuab tsim khoom crucible txawv teb chaws yog tias hom graphite siv, qhov loj me thiab zoo ntawm flake muaj kev ywj pheej ntau dua; Qhov thib ob, cov av nplaum ib txwm muaj tau hloov los ntawm silicon carbide graphite crucible, uas tau los ua nrog kev qhia txog cov thev naus laus zis siab tas li hauv kev lag luam steelmaking.
Furuite graphite kuj tseem siv tau rau hmoov graphite los ntawm kev siv tshuab siab tas li. Hauv av nplaum graphite crucible, cov flake graphite loj nrog 90% cov ntsiab lus carbon suav txog li 45%, thaum nyob rau hauv silicon carbide graphite crucible, cov ntsiab lus ntawm cov khoom loj flake ntawm graphite hmoov tsuas yog suav rau 30%, thiab cov ntsiab lus carbon ntawm graphite raug txo kom txog 80%.
