siab carbon Ferro Chrome
Cov txheej txheem smelting ntawm high carbon ferrochrome muaj xws li blast furnace method, hluav taws xob rauv txoj kev, plasma furnace method, thiab lwm yam. Blast furnaces tsuas yog tsim tshwj xeeb npua hlau uas muaj txog 30% chromium.
nruab nrab carbon ferrochrome
Tam sim no, feem ntau high-carbon ferrochrome nrog cov ntsiab lus siab chromium yog smelted hauv submerged arc furnaces siv txoj kev flux. Lub hauv paus ntsiab lus ntawm smelting high-carbon ferrochrome los ntawm cov hluav taws xob rauv txoj kev yog siv carbon los txo cov chromium thiab hlau oxides nyob rau hauv chromium ore. Qhov pib kub ntawm carbon txo ntawm chromium oxide los tsim Cr2C2 yog 1373K, qhov pib kub ntawm cov tshuaj tiv thaiv ntawm generating Cr7C3 yog 1403K, thiab qhov pib kub ntawm cov tshuaj tiv thaiv ntawm txo chromium rau chromium yog 1523K. Yog li ntawd, thaum carbon txo chromium ore, dab tsi tau txais yog chromium carbide, tsis yog xim hlau chromium.
Nitrited Tsawg Carbon Ferro Chrome
Cov ntsiab lus carbon hauv ferrochromium nyob ntawm qhov ntsuas kub. Nws yog qhov yooj yim dua los tsim cov carbide nrog cov ntsiab lus carbon siab dua li carbides nrog cov ntsiab lus qis carbon.
