Txhawm rau kom nkag siab koj txoj kev nkag siab ntawm cov hlau silicon hmoov, kab lus no feem ntau yuav tsom mus rau cov hlau silicon hmoov hauv kev lag luam foundry los ua lub luag haujlwm hauv deoxidation ntawm cov lus piav qhia ntiav.
Hauv kev lag luam foundry kom ua tiav cov khoom tsim, ntxiv qhov tsim nyog ntawm cov hlau silicon hmoov, tuaj yeem ua lub luag haujlwm hauv deoxidation. Hlau silicon hmoov tuaj yeem hloov ferrosilicon, txo cov nqi tsim khoom thiab txhim kho qhov zoo ntawm castings. Silicon hlau hmoov thiab kua slag theem los yog kua hlau nyob rau hauv cov pa oxygen sib sib zog nqus cov tshuaj tiv thaiv, xav kom tso ib tug loj npaum li cas ntawm tshav kub ntawm combustion, vim hais tias cov tsim ntawm SiO2 nyob rau hauv cov ntaub ntawv no sai sai khiav, ntxiv dag zog rau cov tshuaj tiv thaiv ntawm lub kinetic tej yam kev mob, cov cuab yeej no pab tau heev. rau cov txheej txheem deoxidation.
Rau cov cupola, uas tsis tshua muaj txiaj ntsig, cov nyhuv deoxidising tuaj yeem tsuas yog qhia hauv cov ntsiab lus dav dav. Cov txheej txheem melting (xws li huab cua txias, kev siv cov cua thib ob, cov pa oxygen, cua kub, acidic, alkaline, tsis muaj hauv ob sab phlu) thiab nyob rau hauv cov txheej txheem melting ib ntus coj los hloov cov yam tseem ceeb yuav ua rau muaj kev cuam tshuam tseem ceeb.
Qhov tseeb, silicon hlau hmoov tuaj yeem siv tsis tau tsuas yog rau kev lag luam foundry, tab sis kuj rau lwm yam lag luam. Yog tias koj txaus siab rau silicon hlau hmoov thiab xav paub txog daim ntawv thov ntawm silicon hlau hmoov hauv lwm cov lag luam, koj tuaj yeem tiv tauj peb lub tuam txhab. Peb lub tuam txhab tuaj yeem muab koj cov hmoov zoo silicon hlau hmoov, ntxiv rau, peb lub tuam txhab tseem yuav muab koj cov ntaub ntawv ntau ntxiv txog silicon hlau hmoov thiab lwm yam ntaub ntawv metallurgical.
Peb tuaj yeem xa cov qauv dawb.
