Siab carbon ferrosiliconFeem ntau siv hauv steel mills feem ntau vim nws muaj ntau yam zoo thiab siv tau, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem steel smelting:
Muaj zog deoxidation nyhuv:
High carbon ferrosilicon muaj zog heev txo cov khoom vim nws cov feem ntau ntawm cov pa roj carbon. Hauv cov txheej txheem steelmaking, qhov sib ntxiv ntawm cov pa roj carbon ntau ferrosilicon tuaj yeem txo cov pa oxygen hauv cov hlau molten sai, yog li deoxidizing zoo. Qhov no yog ib kauj ruam tseem ceeb los xyuas kom meej cov ntsiab lus tsis tshua muaj oxygen thiab cov qauv zoo hauv cov hlau. Cov ntsiab lus qis dua cov pa oxygen pab txhim kho cov khoom siv dag zog thiab kev tiv thaiv corrosion ntawm cov hlau, ua rau cov khoom siv hlau kawg zoo dua.
Alloying nyhuv:
Cov pa roj carbon ntau ferrosilicon tsis yog tsuas yog deoxidizer, tab sis kuj tuaj yeem qhia cov ntsiab lus alloying, tshwj xeeb tshaj yog silicon thiab carbon, rau hauv cov hlau. Silicon tuaj yeem txhim kho qhov nyuaj thiab lub zog ntawm cov hlau, thaum txhim kho nws cov hnav tsis kam thiab corrosion kuj. Qhov sib ntxiv ntawm cov pa roj carbon monoxide kuj tuaj yeem cuam tshuam rau cov qauv lattice thiab cov khoom ntawm cov hlau, ua rau cov hlau muaj kev ua tau zoo dua hauv ntau yam kev siv.
Yooj yim rau siv:
Cov pa roj carbon ntau ferrosilicon muaj cov ntsiab lus melting tsawg, uas ua rau nws yooj yim rau ntxiv thiab sai sai yaj thiab hnov mob thaum lub sij hawm steelmaking txheej txheem. Qhov yooj yim ntawm kev siv no yog ib qho txiaj ntsig tseem ceeb heev rau kev tsim khoom thiab kev tswj xyuas kev ua haujlwm ntawm steel mills.
Nqi-effectiveness:
Txawm hais tias cov pa roj carbon ferrosilicon siab yuav kim, nws cov txiaj ntsig ntawm kev txhim kho steel zoo thiab kev ua haujlwm feem ntau yog qhov tseem ceeb, uas yog qhov kev xaiv tsim nyog rau kev lag luam thaum xav txog cov nqi tsim khoom thiab cov khoom zoo kawg.
Nyob rau hauv cov ntsiab lus, siab carbon ferrosilicon tseem dav siv nyob rau hauv steel mills vim nws muaj zog deoxidation muaj peev xwm, alloying nyhuv, yooj yim ntawm kev siv thiab nqi-zoo. Nws yog ib qho tseem ceeb ntawm cov khoom siv los xyuas kom meej qhov zoo thiab ruaj khov ntawm cov hlau, thiab tseem ceeb heev rau kev txhim kho kev lag luam steel niaj hnub.
