SiBa Ca yog ib tug zoo tshiab deoxidizer nyob rau hauv steelmaking, thiab muaj zoo desulfurization thiab phosphorus muaj peev xwm. Nws ua lub luag haujlwm tseem ceeb hauv cov qib hlau smelting nrog tsawg leej faj thiab phosphorus, thiab muaj cov ntawv thov dav dav hauv cov txheej txheem steel tshwj xeeb.
Si Ba Ca alloy yog cov khoom sib xyaw tshiab hauv cov hlau nplaum, uas yog deoxidizer, desulfurizer thiab dephosphorizer hauv steelmaking. Nws yog ib qho inoculant thiab modifier hauv casting. Barium txo qhov vapor siab ntawm calcium thiab ua rau kom cov calcium solubility hauv molten steel nyob rau hauv qhov ntau ntawm steelmaking kub. Piv nrog rau silicon calcium alloy, thaum silicon barium calcium alloy yog siv los ua cov calcium uas ntxiv rau hauv cov hlau molten, cov ntsiab lus calcium hauv cov hlau molten yog li ob npaug ntawm cov silicon calcium alloy txawm tias cov ntsiab lus calcium yog ib nrab ntawm silicon calcium alloy. Nws qhia tau hais tias silicon barium calcium tuaj yeem deoxidized dua thaum txhim kho kev ua haujlwm ntawm calcium kev kho ntawm cov hlau molten. Cov tshuaj muaj pes tsawg leeg (qhov hnyav feem pua) ntawm silicon barium calcium yog 30 ~ 60 feem pua Si, 5 ~ 20 feem pua Ba, 3 ~ 20 feem pua Ca, thiab cov nyiaj seem yog Fe thiab inevitable impurities. Txoj kev npaj ntawm calcium barium silicate yog muab cov ntaub ntawv raw mus rau hauv lub submerged arc rauv raws li cov tshuaj xam zauv feem (qhov hnyav) rau txo smelting. Cov ntaub ntawv raw siv yog silica, celestite, barite, limestone los yog txiv qaub, thiab steel chips (npaj raws li cov khoom muaj pes tsawg leeg). Cov reductant yog thee, coke, charcoal, thiab lwm yam. Cov khoom siv raw thiab cov neeg ua haujlwm txo qis yog sib xyaw thiab muab tso rau hauv lub qhov cub submerged arc, thiab qhov yuav tsum tau muaj silicon barium calcium alloy yog smelted los ntawm ib tug txo. Cov ntsiab lus ntawm calcium nyob rau hauv silicon barium calcium yog tsim nyog, uas overcomes lub shortcomings ntawm tsim cov pa luam yeeb thiab paug ib puag ncig nyob rau hauv lub yav dhau los deoxidation txheej txheem.
