ferro silicon 70
Cov carbonaceous txo cov neeg ua haujlwm siv los tsim ferroalloys feem ntau suav nrog metallurgical coke, roj av coke, pitch coke, bituminous thee thiab charcoal (los yog ntoo blocks). Ntawm lawv, metallurgical coke yog siv ntau tshaj plaws, thiab plaub tom kawg yog siv los tsim kev lag luamsilicon. Bituminous thee thiab charcoal feem ntau siv ua ke nrog metallurgical coke los tsim calcium silicon alloys. Tsis tas li ntawd, carbonaceous txo cov neeg ua haujlwm xws li roj coke coke, semi-coke, silica coke thiab lignite coke kuj tau kawm lossis sim. Feem ntau, coke tau los ntawm retorting ntawm qhov kub siab tshaj 900 degree yog hu ua high-temperature coke, thiab qhov retorting kub yog qis dua 700 degree. Cov coke tau los ntawm C yog hu ua low-temperature coke los yog semi-coke. Piv nrog cov kub-kub coke, qis-kub coke muaj cov tshuaj lom neeg zoo dua thiab muaj kev tiv thaiv loj dua.
