Silicon-barium-calcium alloy yog steelmaking deoxidizer feem ntau muaj calcium carbide (35-45%), silicon dioxide (40-45%), thiab barium sulfate (10-30%). Nws kuj ua haujlwm raws li desulfurizer thiab dephosphorizer, thiab yog siv dav hauv cov hlau tshwj xeeb smelting. Cov alloy no belongs rau tsev neeg barium-based composite alloy thiab tuaj yeem siv los ua cov inoculant thiab hloov kho.
Barium zoo txo qhov vapor siab ntawm calcium thiab nce nws cov solubility hauv molten steel nyob rau hauv lub steelmaking kub ntau. Thaum cov nyiaj ntawm silicon-barium-calcium alloy ntxiv yog ib nrab ntawm silicon-calcium alloy, calcium cov ntsiab lus nyob rau hauv cov hlau molten tuaj yeem ncav cuag ob npaug ntawm silicon-calcium alloy, thiab kev ruaj ntseg ntawm calcium yog txhim kho. Nws qhov zoo muaj xws li kev txhim kho steel fluidity, daws qhov teeb meem ntawm cov nodule tsim nyob rau hauv nruam casting nozzles, txhim kho silicon -manganese rov qab tus nqi, thiab txo cov pa roj carbon hmoov noj. Nws tuaj yeem hloov cov khoom siv deoxidizing ib txwm muaj xws li txhuas hlau thiab silicon-calcium hlau. Cov qib tseem ceeb suav nrog Si50Ba15Ca10 thiab Si50Ba13Ca13, nrog cov tshuaj sib xyaw ua ke raws li cov neeg siv khoom xav tau.
Silicon-barium-calcium yog barium-raws li kev sib xyaw alloy, feem ntau muaj silicon (Si), barium (Ba), thiab calcium (Ca). Nws yog ib hom tshiab ntawm kev sib xyaw deoxidizer siv hauv steelmaking, thiab tseem tuaj yeem siv los ua desulfurizer, dephosphorizer, inoculant, thiab modifier hauv casting.
