Smelting Method ntawm Blast Rauv
Blast furnace method. Txoj kev blast furnace feem ntau tsim cov pa roj carbon ferromanganese. Thaum lub sij hawm smelting, manganese ore, coke thiab flux yog feem loaded mus rau hauv lub cub tawg los ntawm sab saum toj ntawm lub cub tawg, thiab high-temperature cua sov los yog oxygen-nplua nuj yog tshuab mus rau hauv lub cub tawg los ntawm lub tuyere, thiaj li hais tias cov coke combustion tau kub kom txo tau. cov tshuaj tiv thaiv, thiab cov hlau molten thiab slag tau sau rau hauv lub tog raj kheej lub cub tawg, thiab cov slag thiab hlau raug tso tawm tsis tu ncua thiab tapped, thiab cov ntaub ntawv tshiab txuas ntxiv ntxiv raws li tus nqi melts thiab dab dej, thiab cov khoom tsim tawm tsis tu ncua.
Cov txheej txheem blast furnace tsim ferroalloys, uas muaj cov khoom lag luam siab thiab tus nqi qis. Txawm li cas los xij, vim qhov kub tsis tshua muaj nyob rau hauv qhov cub tawg, cov hlau yog tag nrho saturated nrog carbon nyob rau hauv blast furnace smelting tej yam kev mob. Nws feem ntau tsuas yog siv los tsim cov khoom yooj yim txo qis ferroalloys thiab qib qis ferroalloys, xws li cov pa roj carbon ferromanganese, manganese-nplua nuj slag thiab ferronickel.
