Khoom Description
Silicon hlau tau dhau los ua ib qho tseem ceeb hauv cov txheej txheem steelmaking. Qhov sib ntxiv ntawm silicon hlau rau hlau txhim kho nws qhov zoo thiab kev ua haujlwm thaum tseem txo cov nqi tsim khoom. Nws yog ib qho txiaj ntsig zoo ntawm kev txhim kho cov yam ntxwv xav tau ntawm txhua yam khoom siv hlau.
Lub hauv paus yog vim li cas rau kev siv dav ntawm silicon hlau hauv kev lag luam steelmaking yog nws lub peev xwm los deoxidize molten steel. Thaum lub sij hawm tsim cov txheej txheem, muaj cov pa oxygen hauv cov hlau molten tuaj yeem txo nws qhov zoo thiab ua haujlwm ntev. Silicon hlau ua lub luag haujlwm tseem ceeb ntawm kev tshem tawm cov pa oxygen thiab lwm yam impurities los ntawm kev sib txuas nrog lawv, tiv thaiv kom tsis txhob muaj kab mob hauv cov hlau.
Lwm qhov txiaj ntsig tseem ceeb ntawm kev siv cov hlau silicon hauv steelmaking yog nws lub luag haujlwm hauv kev tswj cov ntsiab lus carbon ntawm cov khoom kawg. Qhov sib ntxiv ntawm silicon hlau rau molten steel pab stabilize carbon thiab tiv thaiv nws evaporation, uas yuav ua rau undesirable inconsistencies nyob rau hauv carbon qib. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov hlau zoo li stainless hlau.
Ntxiv mus, qhov sib ntxiv ntawm silicon hlau ua rau kev txhim kho hauv cov khoom siv thiab tshuaj lom neeg ntawm cov hlau. Nws txhim kho cov hlau lub zog, ductility, thiab corrosion kuj, ua rau nws ruaj khov thiab kav ntev. Silicon hlau tseem txhawb kev tsim cov tawv tawv, hnav-tiv taus txheej ntawm cov hlau, txo qhov hnav thiab tsim kua muag thaum siv.
Cov txheej txheem ntawm kev siv cov hlau silicon hauv steelmaking yog yooj yim thiab tuaj yeem yooj yim ua ke rau hauv cov txheej txheem steel uas twb muaj lawm. Nws paub tias yog ib txoj hauv kev pheej yig thiab siv zog ntawm kev txhim kho steel zoo, ua rau cov khoom siv tau zoo kawg nkaus uas muaj kev ua haujlwm siab thiab ua haujlwm ntev.
Hauv kev xaus, silicon hlau tau hloov pauv txoj kev lag luam steel los ntawm kev ua kom nws muaj peev xwm tsim cov khoom siv hlau zoo ntawm tus nqi pheej yig. Nws lub peev xwm los deoxidize steel, tswj cov ntsiab lus carbon, thiab txhim kho cov khoom siv kho tshuab thiab tshuaj lom neeg tsis muaj nuj nqis. Lub neej yav tom ntej zoo li ci ntsa iab rau cov neeg tsim khoom steel uas tau txais kev siv thev naus laus zis tshiab no, qhib kev muaj peev xwm ntau ntxiv rau kev tsim cov khoom siv hlau muaj zog, ruaj khov, thiab kav ntev.
