Silicon-barium-calcium alloy yog ib qho kev sib xyaw ua ke tshiab ntawm barium-raws li alloys. Nws ua haujlwm ua deoxidizer, desulfurizer, thiab dephosphorizer hauv steelmaking; nws kuj ua raws li inoculant thiab hloov kho hauv casting.
Barium zoo txo qhov vapor siab ntawm calcium nyob rau hauv lub steelmaking kub ntau yam, ua rau lub solubility ntawm calcium nyob rau hauv molten steel. Piv rau silicon-calcium alloy, thaum silicon-barium-calcium alloy yog ntxiv rau molten steel ntawm ib nrab ntawm cov calcium, cov ntsiab lus calcium nyob rau hauv cov hlau molten yog kwv yees li ob npaug ntawm silicon-calcium alloy, thiab calcium concentration nyob rau hauv cov hlau molten yog ho nce. Silicon-barium-calcium alloy tuaj yeem txhim kho cov dej ntws ntawm cov hlau molten, daws qhov teeb meem ntawm nozzle clogging nyob rau hauv nruam casting, txhim kho tus nqi rov qab ntawm silicon thiab manganese, thiab txo cov roj carbon hmoov noj. Nws tuaj yeem hloov cov tshuaj deoxidizers xws li txhuas hlau thiab silicon-calcium hlau. Nws yog qhov tsim nyog tshwj xeeb rau kev tsim cov khoom qis-sulfur, qis-phosphorus steel thiab cov hlau tshwj xeeb. Hauv casting, nws cov ntawv thov tseem ceeb suav nrog cov hlau nplaum thiab grey cam khwb cia hlau.
