High-carbon ferrochrome ntau lawm txoj kev muaj xws li hluav taws xob rauv txoj kev, lub qhov cub rauv (blast furnace), txoj kev ntshav plasma thiab txoj kev txo yaj. Cov txheej txheem ntawm lub tshuab hluav taws xob tam sim no tsuas yog tsim cov chromium alloy tsawg (Cr < 30%), cov ntsiab lus chromium ntau dua (xws li Cr> 60%) ntawm cov txheej txheem tsim hluav taws xob yog tseem nyob rau theem tshawb fawb; ob txoj kev tom kawg tau tshawb nrhiav hauv cov txheej txheem tshwm sim; Yog li ntawd, feem ntau ntawm cov lag luam high-carbon ferrochrome thiab remanufactured ferrochrome yog siv nyob rau hauv zus tau tej cov hluav taws xob furnaces (mineral furnace) txoj kev.
(1) Lub tshuab hluav taws xob siv hluav taws xob, lub zog huv tshaj plaws. Lwm qhov chaw siv hluav taws xob xws li thee, coke, roj crude, nkev roj, thiab lwm yam yuav inevitably coj cov impurity nrog rau hauv cov txheej txheem metallurgical. Tsuas yog lub tshuab hluav taws xob tuaj yeem tsim cov hlau huv tshaj plaws.
(2) Hluav taws xob yog tib lub zog hluav taws xob uas tuaj yeem tau txais kev kub ntxhov siab.
(3) Lub tshuab hluav taws xob hluav taws xob tuaj yeem yooj yim paub txog cov txheej txheem thermodynamic xws li oxygen ib nrab siab thiab nitrogen ib feem siab xav tau los ntawm ntau yam kev cuam tshuam metallurgical xws li txo qis, kho kom zoo thiab nitriding.
