Electrofused calcium aluminate, tseem hu ua pre-melting refining slag los yog pre-melting aluminium calcium slag, tau ntev tau siv nyob rau hauv txawv teb chaws, xws li South Kauslim, Nyiv, Europe thiab lub tebchaws United States thiab lwm lub teb chaws tsim.
Cov muaj pes tsawg leeg yog uniform thiab lub melting point yog tsawg, thiab lub sij hawm smelting yuav luv luv; Lub slag viscosity thiab ntws yog tsim los txhawb lub deoxidation thiab desulphurization ntawm slag thiab cov hlau molten; ceev desulfurization, cov nyhuv yog ruaj khov ntawm 60 feem pua, thiab cov phosphorus rov qab tau zoo suppressed; qhov zoo adsorption ntawm inclusions muaj txiaj ntsig zoo rau kev ua kom huv ntawm cov hlau, kev tiv thaiv ntawm lub ladle hauv ob sab phlu thiab tiv thaiv cov slag yaig; cov muaj pes tsawg leeg yog uniform thiab tsim. Lub slag yog ceev, thiab cov plua plav paug tuaj yeem txo.
Tsis tas li ntawd, peb tseem tuaj yeem npaj cov khoom loj raws li cov tshuaj muaj pes tsawg leeg xav tau los ntawm tus neeg siv, thiab khaws nws tsis pub lwm tus paub rau tus neeg siv.
Thaum deoxidation yog txoj hauv kev tseem ceeb, ncaj qha ntxiv rau hauv qab ntawm lub ladle ua ntej tapping; tus nqi ntxiv yog txiav txim siab los ntawm cov ntsiab lus carbon ntawm cov hlau molten ntawm qhov kawg taw tes, feem ntau raws li 4-6kg / 1000kg steel; Ferrosilicon thiab aluminium; manganese thiab ferrosilicon yog conventionally ntxiv rau carbon structural steel tom qab tapping, tsis ntxiv lwm yam alloys los yog txhuas los pub cov hlau, thiab cov hlau molten nyob rau hauv lub ladle tsuas yog yuav tsum tau refined los ntawm tshuab argon; siv cov khoom no rau deoxidation, tus nqi ntawm carburizer (silicon carbide) tuaj yeem txo los ntawm 30-50 feem pua
Thaum desulfurization yog txoj hauv kev tseem ceeb, 1/3 ntawm cov nyiaj siv ua ntej hauv qab ntawm lub hnab yog qhov zoo, tab sis nws yuav tsum tau ntxiv rau ntawm qhov cuam tshuam ntawm cov hlau ntws hauv qab ntawm lub hnab; 2/3 ntawm cov nyiaj ntxiv thaum cov hlau molten ntws tawm; tus nqi ntawm cov hlau siv yog 6-8kg / 1000kg, nyob ntawm seb tus thawj cov ntsiab lus ntawm cov hlau molten thiab cov nyhuv ntawm kev siv yog txiav txim siab.
