Muaj silicon carbide SiC 88-90%: cov khoom siv txhim khu kev qha rau niaj hnub metallurgical ntau lawm
Silicon carbide (SiC) muaj88-90%yog ib qho ntawm cov khoom siv nrov tshaj plaws hauv kev lag luam metallurgical. Vim nws cov ntsiab lus SiC siab, tsis muaj impurity theem thiab zoo heev txo cov khoom, nws yog dav siv nyob rau hauv steel, hlau thiab foundry industries raws li ib tug zoo deoxidizer, txo tus neeg sawv cev thiab qhov chaw ntawm silicon thiab carbon.
Dab tsi yog industrial SiC 88-90%
Muaj silicon carbide yog tsim nyob rau hauv hluav taws xob furnaces los ntawm high-kub txo ntawm quartz xuab zeb nrog carbonaceous cov ntaub ntawv. Tom qab crushing, sorting thiab kev faib tawm, cov khoom ntawm ntau qhov feem ntau tau txais uas ua tau raws li cov kev cai ntawm cov tuam txhab metallurgical.

Cov txiaj ntsig tseem ceeb ntawm SiC 88-90%
High deoxidation efficiency
Silicon carbide nquag khi cov pa oxygen hauv cov hlau molten, txo tus naj npawb ntawm cov khoom tsis yog hlau thiab txhim kho kev huv ntawm cov hlau.
Kev nce qib ntawm silicon absorption
Kev siv SiC tso cai rau kev qhia ib txhij ntawm silicon thiab carbon, uas ua rau muaj kev ruaj ntseg ntawm cov hlau.
Txo ferrosilicon noj
Hauv ntau cov txheej txheem thev naus laus zis, SiC ib feem hloov ferrosilicon, uas pab txo cov nqi tsim khoom yam tsis muaj kev cuam tshuam cov khoom zoo.
Txhim kho qhov zoo ntawm cam khwb cia hlau
Hauv kev tsim cov hlau grey thiab ductile hlau, silicon carbide txhawb nqa graphitization, txhim kho cov khoom siv kho tshuab thiab txo qhov kev pheej hmoo ntawm qhov tsis xws luag.
Siab thermal stability
Cov khoom khaws cia nws cov khoom ntawm qhov kub thiab txias thiab ua kom ruaj khov ntawm cov khoom siv hlau.
Daim ntawv thov
Industrial SiC 88-90% yog siv rau hauv ntau yam txheej txheem metallurgical:
Kev tsim cov qauv thiab cov hlau alloy
Smelting ntawm grey thiab high-lub zog cam khwb cia hlau
Hluav taws xob Arc Furnaces (EAF)
Induction rauv
Foundries
Ferroalloy ntau lawm
Vim li cas cov tuam txhab metallurgical xaiv SiC 88-90%
Kev siv cov khoom siv silicon carbide tso cai rau:
txo kev noj cov khoom siv alloying kim;
nce cov qoob loo ntawm usable hlau;
txhim kho qhov zoo ntawm cov castings;
txo tus nqi ntawm slag;
nce kev ruaj ntseg ntawm cov txheej txheem ntau lawm;
optimize cov nqi tsim khoom.
