Ferro calcium silicon sawv ua cov khoom siv pob zeb hauv kev nrhiav cov khoom zoo hlau thiab hlau. Nws lub peev xwm tshwj xeeb rau tib lub sijhawm deoxidize, desulfurize, thiab hloov cov kev suav nrog ua rau nws tsis tuaj yeem hloov pauv hauv cov haujlwm niaj hnub metallurgical. Los ntawm kev hloov tsis zoo impurities rau hauv benign los yog cov ntaub ntawv muaj txiaj ntsig, nws txhim kho kev ua haujlwm zoo, ua haujlwm ntev, thiab kev tsim khoom ntawm ntau yam khoom lag luam.

Rau steelmakers thiab foundry tswv, tus yuam sij rau kev qhib lub peev xwm ntawm cov hlau no nyob rau hauv cov txheej txheem meej. To taub qhov sib cuam tshuam ntawm qhov kub thiab txias, slag chemistry, thiab lub sijhawm ntxiv yog qhov tseem ceeb. Cov neeg uas paub txog cov kev hloov pauv no tuaj yeem ua tiav cov kev huv huv zoo tshaj plaws, txo cov nqi tsim khoom, thiab xa cov khoom uas ua tau raws li cov qauv nruj tshaj plaws thoob ntiaj teb.

Leej twg yuav tsum siv cov khoom no? Cov hlau no zoo tagnrho rau cov neeg tsim khoom ntawm HSLA steels, cov khoom siv hauv cov kav dej, cov ntawv sau tsheb, thiab cov khoom ua haujlwm siab. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau cov chaw nrhiav kev txhim kho lawv cov khoom zoo yam tsis muaj kev nqis peev hauv cov txheej txheem hlau txhaj tshuaj complex. Koom tes nrog cov chaw tsim khoom raws caij nyoog xws li Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd. xyuas kom nkag mus rau cov khoom uas tau dhau los ntawm kev soj ntsuam nruj los ntawm kev ua haujlwm zoo thiab kev saib xyuas kev ua haujlwm, txhawb nqa los ntawm kev cog lus rau kev ncaj ncees thiab kev siv thev naus laus zis.

Cov kauj ruam tom ntej: Yog tias koj tab tom nrhiav kom ua kom zoo dua koj cov txheej txheem steelmaking, ntsuas koj cov qib kev suav nrog tam sim no thiab cov hom phiaj sulfur. Xav txog kev sim nrog qib ferro calcium silicon txhawm rau txiav txim siab qhov zoo tshaj plaws rau koj cov xwm txheej tshwj xeeb. Kev koom tes nrog tus neeg muag khoom uas muaj kev tshuaj ntsuam xyuas tshuaj zoo ib yam, ntau yam khoom lag luam suav nrog cov nodulizers thiab cov xov hlau cored, thiab kev txhawb nqa kev txhawb nqa ntxiv yuav ua kom koj txoj kev vam meej hauv kev tsim cov hlau hauv ntiaj teb.
