Nyob rau hauv Grand Las ntawm steel smatting, silicon-barium alloy ua si ib txoj kev txhawb nqa uas tsis yog ostentatious tab sis tseem ceeb. Qhov no suav cov khoom siv allolo ntawm silicon, Barium thiab tus nqi tsim nyog ntawm irreallurgical kev lag luam nrog nws cov tshuaj lom neeg thiab cov yam ntxwv lub cev. Raws li ib tug zoo deoxidizer thiab desulfurizer, silicon-barium ancloy tuaj yeem txhim kho qhov kev huv huv; Raws li qhov zoo tshaj plaws inoculant, nws tuaj yeem txhim kho cov graphite morphology ntawm cam khwb cia hlau; Thiab raws li ib qho alloy additive, nws muab tshwj xeeb steel ua tau zoo heev. Nws yog cov haujlwm ntau yam uas ua rau silicon-barium ancloy ib qho kev tsim txom "hauv kev lag luam me me" hauv kev lag luam me me.
Cov tseem ceeb ntawm cov khoom sib tw ntawm silicon-barium ancloy yog thawj zaug cuam tshuam rau nws lub peev xwm ua kom muaj peev xwm zoo. Nyob rau hauv cov txheej txheem ntawm steel sminting, oxygen thiab leej faj yog zoo li muaj peev xwm tua neeg, uas yuav cuam tshuam cov khoom siv me me thiab ua cov yam ntxwv ntawm cov hlau. Cov khoom sinicon nquag thiab cov khoom siv barium hauv silicon-barium ancoy muaj qhov muaj kuab lom nrog oxygen nrog cov pa oxygen thiab cov neeg tuaj yeem tsim cov oxide uas muaj kuab thiab cov txiv leej thiab ntab thiab ntab rau daim slag. Cov kev tshawb fawb tau qhia tias thaum siv cov lus si rau kev ua si deoxidation, thiab tus lej desulfed, thiab cov lej desulfed, thiab cov kev ua kom tau ntau dua li cov nyhuv ntawm cov neeg deoxidizidizers. Tseem ceeb tshaj, qhov npau suav kub ntawm barium yog siab npaum li 1640 degree, uas tuaj yeem tsim lub sijhawm ntev ntev thiab nquag ua haujlwm "hauv cov hlau Molten. Qhov kev ua haujlwm dynamic dynamic no ua rau cov tshuaj tiv thaiv ua tiav thiab txhij txhua. Cov ntaub ntawv coj los ntawm lub tuam txhab steel loj qhia tau tias tom qab siv cov khoom siv cua hlau-barium, qhov kev tsim nyog muaj zog ntxiv los ntawm 20%, thiab cov khoom tsim nyog nce ntxiv rau ntau dua 99.3%.
Nyob rau hauv daim teb ntawm cam khwb cia hlau, silicon-barium alloys tau pom meej lwm cov txuj ci txawv tshaj plaw - graphite morphology kev cai. Cov kev ua tau zoo ntawm cam hlau nyob ntawm morphology thiab faib cov graphite, thiab faib cov alloys tuaj yeem hloov cov crystallization ntawm graphite. Barium atoms xaiv adsorb ntawm cov chaw prismatic ntawm Graphite Clearial nthuav dav, incompital radial sprake graphite rau kev nplua thiab cov qauv hluav taws xob zoo li lossis cov qauv sib xyaw. Qhov kev hloov pauv hauv microstructure tau coj los txog ntawm macroscopic ua tau zoo nrog silicon-barium alcoys tuaj yeem nce los ntawm}%, thiab lub elongation} tau nce los ntawm 2-3 lub sij hawm.
