Khoom Description
Ferro Silicon 75Feem ntau yog siv rau smelting high-qib oriented silicon steel, non oriented silicon steel, thiab cov hlau tsis tshua muaj hlau. Lub smelting ntawm ferrosilicon FeSi75 nyob rau hauv lub teb chaws xws li Nyiv, lub tebchaws United States, thiab Norway yuav txo tau ntawm silicon ore, metallurgical coke (+ petroleum coke + charcoal + thee, thiab lwm yam), thiab steel chips (los yog hlau ore) nyob rau hauv ib tug submerged. arc rauv. Qee tus kuj siv cov txheej txheem slag suction sab nraum lub qhov cub kom tshem tawm qee qhov impurities, uas yog txheej txheem nyuaj. Txhua lub tuam txhab tsim hluav taws xob hauv tsev tsim ferrosilicon FeSi75 los ntawm kev txo nws hauv lub qhov cub submerged arc siv silica, metallurgical coke, thiab steel chips.
Lub hauv paus ntsiab lus ntawm ferrosilicon ntau lawm yog txo cov silicon dioxide los ntawm carbon. Hauv kev tsim khoom tshwj xeeb, txhawm rau tshem tawm cov pa oxygen los ntawm silicon dioxide, nws yog ib qho tsim nyog yuav tsum tau nce qhov kub ntawm lub cub tawg thiab txo cov silicon dioxide nrog carbon los ntawm coke, cov roj tshwm sim, xws li carbon dioxide lossis carbon monoxide tuaj yeem raug tshem tawm. los ntawm lub cub tawg thiab silicon tuaj yeem txo ncaj qha.

Kev siv cov khoom
Kev siv lub ntsiab ntawm 75 silicon hlau yog ua tus deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking, nrog rau cov inoculant thiab spheroidizing tus neeg sawv cev hauv kev lag luam cam khwb cia hlau.
Tshwj xeeb, 75% ferrosilicon tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten, txhim kho nws cov purity thiab zoo. Nyob rau tib lub sijhawm, nws tseem tuaj yeem ua cov khoom siv alloying ntxiv los txhim kho kev ua haujlwm ntawm cov hlau.
Tsis tas li ntawd, 75 silicon hlau kuj tseem siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab muaj kev siv hauv lwm qhov chaw.
Kev lag luam hlau: 75% ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steel, uas tuaj yeem ua kom cov hlau zoo thiab txo cov phosphorus thiab sulfur cov ntsiab lus ntawm cov hlau.
Kev lag luam Casting: Ntxiv qhov tsim nyog ntawm 75 silicon hlau rau cov hlau molten tuaj yeem tiv thaiv kev tsim cov carbides thiab txhawb graphite nag lossis daus thiab spheroidization, ua tus neeg sawv cev inoculant thiab spheroidizing.
