Smelting txheej txheem ntawm Ferrosilicon

Ferrosilicon yog ib qho tseem ceeb ferroalloy khoom, dav siv nyob rau hauv steel, casting thiab lwm yam lag luam. Cia peb ua tib zoo saib cov txheej txheem smelting ntawm ferrosilicon.

1. Kev sib xyaw ntawm ferrosilicon
Ferrosilicon yog ib qho hlau uas muaj cov hlau xws li hlau, silicon, carbon, thiab manganese, uas feem ntau cov ntsiab lus silicon feem ntau yog 70% thiab 80%.

2. Lub hauv paus ntsiab lus smelting ntawm ferrosilicon
Lub hauv paus ntsiab lus smelting ntawm ferrosilicon yog txo silica thiab metallurgical coke ntawm qhov kub thiab txias. Qhov sib npaug ntawm cov tshuaj tiv thaiv yog:

SiO2 + 2C → Si + 2CO

Cov tshuaj tiv thaiv no yuav tsum tau nqa tawm ntawm qhov kub thiab txias, thiab qhov sib piv ntawm silica thiab coke yuav tsum tsim nyog, feem ntau 1: 3 ~ 4.

3. Lub ntsiab smelting txoj kev ntawm ferrosilicon
Muaj ntau ntau txoj kev smelting tseem ceeb ntawm ferrosilicon, cov uas feem ntau siv yog tawm ntawm qhov cub thiab hauv qhov cub:

1) Txoj kev smelting tawm ntawm qhov cub

Txoj kev tawm ntawm qhov cub smelting yog sib tov silica, coke thiab molten hlau, yaj lawv ntawm qhov kub thiab txias hauv qhov cub hluav taws xob, thiab tom qab ntawd ncuav tawm cov ferrosilicon alloy tau los ntawm smelting.

2) Rauv smelting txoj kev

Txoj kev ua kom sov yog txhawm rau thauj cov silica, coke thiab molten hlau mus rau hauv cov dej-txias lined rauv feem thiab smelt nyob rau hauv tej yam kev mob, uas yog, molten hlau yog siv nyob rau hauv ib tug loj hluav taws xob rauv kom txo silica thiab tsim ferrosilicon alloy nyob rau tib lub sij hawm. .

4. Cov teeb meem xav tau kev saib xyuas hauv cov txheej txheem smelting ntawm ferrosilicon
1.) Lub smelting ntawm ferrosilicon yuav tsum nruj tswj ntawm smelting tej yam kev mob, tshwj xeeb tshaj yog kub, lub sij hawm thiab cov khoom piv;

2.) Cov alloy muaj pes tsawg leeg yuav tsum tau soj ntsuam tas li thiab kho thaum lub sij hawm smelting txheej txheem kom ntseeg tau tias qhov zoo ntawm ferrosilicon alloy yog ruaj khov thiab ua tau raws li qhov yuav tsum tau ua;

3.) Yog tias muaj teeb meem thiab teeb meem tshwm sim hauv smelting, lawv yuav tsum tau hloov kho thiab kho kom haum rau lub sijhawm kom ntseeg tau tias kev ua tiav ntawm cov txheej txheem smelting.
