Kev piav qhia
High carbon silicon (HC Si) yog ib qho tseem ceeb alloy siv nyob rau hauv steel kev lag luam los txhim kho lub zog thiab zoo ntawm steel khoom. HC Si yog tsim los ntawm kev txo qis carbothermic ntawm quartz los yog xuab zeb nrog coke nyob rau hauv ib qho hluav taws xob arc rauv. Hauv cov txheej txheem no, SiO2 txo qis rau Si, uas ua ke nrog carbon los ua HC Si. Cov txheej txheem ntau lawm muaj ob peb kauj ruam, suav nrog kev npaj cov khoom siv raw, them, melting, refining, thiab casting.
Kev npaj cov khoom siv raw suav nrog kev xaiv cov khoom zoo quartz lossis xuab zeb thiab coke ua qhov tseem ceeb ntawm carbon. Cov khoom siv raw yog ua tib zoo xaiv los xyuas kom meej qhov sib xws ntawm cov nplej loj thiab cov tshuaj muaj pes tsawg leeg, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub cub tawg.
Nyob rau hauv cov kauj ruam them, cov ntaub ntawv raw yog hnyav thiab sib tov raws li ib daim ntawv qhia tshwj xeeb thiab them rau hauv hluav taws xob arc rauv. Tom qab ntawd lub cub tawg yog kaw, thiab cov txheej txheem smelting pib nrog kev siv hluav taws xob tam sim no. Qhov tam sim no tsim kom muaj qhov kub thiab txias, uas ua rau cov nqi hluav taws xob, thiab cov tshuaj lom neeg ua rau kev tsim cov HC Si pib.

Thaum lub sij hawm melting kauj ruam, ib co impurities xws li ferro-silicon, silicon carbide, thiab lwm yam ntaub ntawv insoluble yog tsim. Cov impurities no yuav tsum tau muab tshem tawm, thiab qhov ntawd yog qhov uas cov kauj ruam refining tuaj rau hauv. Refining yuav tsum tau ntxiv cov reagents xws li calcium, txhuas, thiab magnesium los teb cov impurities thiab tshem tawm lawv.
Cov kauj ruam kawg yog qhov casting ntawm HC Si rau hauv daim ntawv xav tau. Lub molten alloy yog poured rau hauv pwm thiab tso cai rau solidify. Thaum ua tiav lawm, HC Si tuaj yeem txiav rau hauv cov me me, crushed, thiab tshuaj xyuas rau qhov yuav tsum tau muaj kev faib tawm.
Hauv kev xaus, kev tsim cov HC Si yog cov txheej txheem nyuaj uas yuav tsum tau ua tib zoo npaj cov tswv yim, tswj cov txheej txheem nruj, thiab kev saib xyuas tas li. Qhov zoo ntawm HC Si yog qhov tseem ceeb vim nws cuam tshuam rau qhov kawg ntawm cov khoom zoo hauv kev lag luam steel. Yog li, kev tsim cov khoom zoo HC Si yog qhov tseem ceeb rau kev lag luam steel los tsim cov khoom siv hlau zoo.
