Nrog rau kev txhim kho txuas ntxiv ntawm Tuam Tshoj txoj kev lag luam, cov ntaub ntawv alloy kuj tau ua tiav zoo hauv kev tsim khoom thiab kev loj hlob. Silicon aluminium barium calcium alloy cov khoom yog tam sim no tsim thiab ua tiav los ntawm cov txheej txheem smelting, xws li electro silicothermic txoj kev thiab carbothermal txoj kev, uas feem ntau yog siv los tsim cov khoom siv hlau no.
Si Al Ba Ca alloy feem ntau yog siv nyob rau hauv Tuam Tshoj txoj kev lag luam steelmaking, thiab muaj kev ua tau zoo deoxidization, uas yog nyiam los ntawm cov neeg siv feem ntau. Nws tuaj yeem deoxidize tsis tu ncua, txhawb cov polymerization sai ntawm qee cov hlau tsis huv hauv cov hlau molten, txhim kho cov morphology ntawm kev suav nrog, thiab ua lub luag haujlwm hauv purifying cov hlau molten; Txhim kho tus nqi rov qab ntawm silicon, manganese thiab lwm yam alloys, uas tuaj yeem txo qhov sib ntxiv ntawm cov hmoov carbon, txuag cov peev txheej thiab txo cov nqi; Cov nyhuv deoxidation yog qhov zoo, uas ua lub luag haujlwm hauv qhov teeb meem nodulation ntawm lub casting nozzle thiab ua rau cov hlau dej ntws zoo dua; Kev ua haujlwm yog yooj yim. Thaum peb siv cov khoom no, nws tuaj yeem ua tiav yam tsis muaj lwm yam khoom siv tshiab. Si, Al, Ba, Ca muaj cov yam ntxwv ntawm qis melting point, ceev ceev diffusion, spheroidizing inclusions nyob rau hauv molten steel, hloov cov duab ntawm inclusions, ceev tapping thiab shortening smelting lub sij hawm. Kev tsim cov calcium aluminosilicate barium yuav tsum muaj qee yam thev naus laus zis. Piv txwv li, thaum qee cov ntsiab lus ntxiv, calcium oxide thiab coke yuav tsum tau ntxiv rau hauv cov khoom siv los txhawb kev tsim cov calcium silicate aluminium, thiab tom qab ntawd barium ore thiab coke yuav tsum tau ntxiv rau hauv cov khoom siv los txhawb kev tsim ntawm silicon calcium barium aluminium alloy. Cov txheej txheem ntawm braising thiab hlawv yuav tsum tau saws txij thaum pib mus txog rau thaum xaus, thiab cov slags yuav tsum tau kho los ntawm kev ntxiv calcium oxide thiab barium oxide kom tshem tawm ntawm lub cub tawg. Xav txog kev txhim kho cov nyhuv refining thiab txuag hluav taws xob, txoj kev steelmaking tsis muaj slag lossis nrog slag tsawg yog npaj.
