Nyob rau hauv tus txheej txheem ntawm smelting, yuav muaj ntau yam deoxidizers. Kev xaiv thiab daim ntawv thov tiag tiag yuav ua raws li qhov xav tau sib txawv. Silicon aluminium barium calcium kuj yog ib hom kev sib xyaw deoxidizer. Piv nrog rau lwm cov deoxidizers xws li ferrosilicon, muaj ntau deoxidizing ntsiab nyob rau hauv silicon aluminium barium calcium. Raws li kev sib xyaw ua ke ntawm ntau lub ntsiab lus, nws kuj tseem muaj txiaj ntsig zoo rau cov hlau zoo.
Raws li cov deoxidizer rau steelmaking, SiAlBaCa muaj kev ua haujlwm zoo deoxidization thiab tuaj yeem txhim kho qhov purity ntawm molten steel. Nyob rau hauv cov txheej txheem ntawm steelmaking, SiAlBaCa ua raws li deoxidizer thiab desulfurizer kom txo tau cov pa oxygen nyob rau hauv molten steel, thiab txhuas, silicon, barium, calcium thiab lwm yam khoom tsim oxides, uas tseem yuav ntab rau saum npoo ntawm molten steel, muab yooj yim rau purifying. molten steel, Yog li txhawm rau txhim kho cov hlau zoo, uas tseem yog lub luag haujlwm tshwj xeeb ntawm silicon aluminium barium calcium khoom. Tau kawg, qhov no kuj yog vim li cas cov khoom siv no tau siv dav. Cov khoom siv no tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov hlau molten thiab daws qhov teeb meem ntawm nozzle nodulation. Thaum siv cov deoxidizer, qhov zoo yog qhov tseem ceeb heev rau theem tom qab deoxidation. Cov calcium hauv silicon aluminium barium calcium kuj tseem tuaj yeem muab cov calcium ntxiv rau cov hlau nyob rau theem tom qab ntawm cov hlau smelting, Yog li, cov ntsiab lus calcium hauv cov hlau tuaj yeem txhim kho, uas muaj txiaj ntsig zoo rau kev hnav thiab tawv tawv ntawm cov hlau. Barium nyob rau hauv SiAlBaCa txo cov vapor siab ntawm calcium thiab ua rau kom lub solubility ntawm calcium nyob rau hauv molten steel nyob rau hauv qhov ntau ntawm steelmaking kub.
