Ferro Silicon Alloy Cov Txheej Txheem Ntau Lawm
Raw Khoom Npaj
Xaiv cov siab -} Zoo quartz, coke, thiab hlau ore ua cov khoom nyoos. Quartz yuav tsum muaj cov ntsiab lus silicon siab Hlau ore yog xaiv raws nws cov hlau qib thiab cov ntsiab lus impurity. Cov ntaub ntawv raw no yog cov ntaub ntawv raug yog raws li cov muaj feem pua sib xyaw ua ke thiab tom qab ntawd crushed thiab tshuaj ntsuam kom ntseeg tau qhov loj me me rau smelting.
Smelting txheej txheem
Lub npaj cov ntaub ntawv raw rau hauv submerged - arc rauv. Nyob rau hauv lub cub tawg, nyob rau hauv high - tej yam kev mob siab (feem ntau nyob ib ncig {}} degree), muaj kev sib tw ntawm cov tshuaj lom. Cov pa roj carbon hauv coke txo cov sillicon dioxide hauv Quartz los tsim cov hlau hauv cov hlau hauv cov hlau hauv cov} {}}} hlau hlau. Cov txheej txheem smelting yuav tsum tau tswj hwm hluav taws xob nruj me ntsis, ua kom sov sov, thiab sijhawm ntau dhau los ua kom zoo thiab tawm los ntawm cov alloy.
Refining Txheej Txheem
Tom qab smelting, the molten silicon -} Iron hlau alloy yog kho kom tshem tawm impurities. Qhov no yuav suav nrog cov txheej txheem xws li sleag {2} Cov hlau sib cais kom tshem tawm cov tshuaj lom neeg uas tsis txaus ntseeg thiab txhim kho cov tshuaj lom neeg thiab txhim kho txoj kev coj dawb huv ntawm cov alloy.
Casting thiab cua txias
Lub ntsej muag ua kom zoo nkauj ntawm alloy raug pov rau hauv pwm ntawm cov duab tsim nyog, xws li kev cuam tshuam. Tom qab ntawd, cov duab cas yog txias kom tsis txhob muaj kev ntxhov siab sab hauv thiab ua kom cov txheej txheem kev ncaj ncees ntawm cov alloy. Tom qab txias, cov silicon -} Iron ecloy ingots tau npaj rau kev ua haujlwm ntxiv lossis ntim khoom.
