Nitrided Ferro Chrome
Cov sulfur nyob rau hauv high-carbon ferrochrome yog los ntawm raw cov ntaub ntawv, uas coke thiab chromium ore coj nyob rau hauv feem ntau ntawm cov sulfur. Cov sulfur hauv coke muaj nyob rau hauv daim ntawv ntawm sulfide (FeS, CaS) los yog organic sulfur. Hauv cov txheej txheem tsim khoom tiag tiag, cov ntaub ntawv raw 8% ~ 15% ntawm cov sulfur hauv cov hlau nkag mus rau hauv cov hlau, 20% ~ 30% volatilizes, thiab 60% ~ 70% nkag mus rau slag. Cov sulfur nkag mus rau hauv cov hlau yuav tsim cov sulfides nrog chromium, xws li: CrS, Cr2S3, thiab lwm yam. CrS melts tsis decomposing ntawm 1565C, thiab decomposes rau Cr15S6 hauv qab 800C. Txij li thaum lub melting point ntawm sulfides qis dua li ntawm ferrochrome, cov sulfides yog faib rau saum npoo ntawm high carbon ferrochrome.
