Cov nplua nuj manganese slag molten hlau ladle cov ntaub ntawv nyob rau hauv ib puag ncig acidic, thiab lub slag tag nrho yog raug rau qaug zog acid thiab nruab nrab erosion, thaum manganese yog alkaline thiab yuav ua kom cov tshuaj nkag mus yaig. Qhov sib xyaw ntawm cov nplua nuj manganese slag molten hlau ladle yog qhov piv ntawm 2: 1 ntawm nplua nuj manganese slag thiab molten hlau. Nyob rau hauv no complex erosion huab cua, xaiv cov khoom siv rau lub ladle hauv ob sab phlu yog qhov tseem ceeb heev.
Feem ntau, refractory bricks yog siv raws li lub hauv ob sab ntau zaus. Thaum siv cov cib refractory li hauv ob sab phlu, nws yog ib qho tsim nyog yuav tau xav txog qhov yaig cua. Av nplaum cib thiab siab alumina cib tsis muaj zog tiv thaiv - muaj peev xwm yaig thiab tsis pom zoo. Lub slag kab cheeb tsam muaj ib tug siab piv ntawm slag rau hlau, thiab lub slag ntim nyiaj rau ib tug loj feem. Qhov chaw slag kab yog qhov chaw puas tsuaj loj. Yog tias siv cov cib refractory li hauv ob sab phlu, nws yog qhov zoo tshaj los xaiv aluminium-carbon silicon carbon cib. Cov yam ntxwv ntawm aluminium-carbon silicon carbon bricks yog ruaj khov thiab haum rau kev siv thermal cycling nquag.
Cov khoom siv hauv ob sab phlu zoo tshaj plaws yog cov av nplaum los yog qib peb qib siab alumina cib ua cov txheej txheem ruaj khov, cov iav dej ua ke txhuas -carbon silicon carbon cib ua cov txheej txheem ua haujlwm ntawm lub ladle phab ntsa, resin ua ke aluminium-carbon silicon carbon cib rau lub ladle hauv qab, qis - carbon magnesium carbon cib rau cov kab slag{3} sib txuas hluav taws av nplaum.
Yog tias muaj pwm, aluminium -carbon silicon carbon casting khoom siv tau los ua hauv ob sab phlu. Txawm li cas los xij, cov ntsiab lus ntawm silicon carbide thiab carbon yuav tsum tsis txhob qis dua 17%. Nws yog qhov zoo tshaj plaws kom muaj cov ntsiab lus ntawm 12% -14% rau silicon carbide thiab 5% rau carbon, nrog 2.5% ntawm cov hlau silicon rau oxidation kuj. Tom qab vibrating pwm thiab tshem tawm cov pwm tom qab 1-2 hnub, nws yuav tsum tau muab ci rau hauv qhov cub ci raws li qhov ci nkhaus ntawm cov chaw tsim khoom ua ntej muab tso rau hauv kev siv.
Thaum xaiv aluminium-carbon silicon carbon bricks lossis aluminium-carbon silicon casting khoom rau lub ladle hauv ob sab phlu, nws yuav tsum tau ua raws li cov cuab yeej ntawm qhov chaw. Cov khoom siv casting yuav tsum muaj pwm thiab lub qhov cub ci. Cov khoom siv casting hauv ob sab phlu muaj cua nruj thiab yooj yim rau kev txij nkawm. Txhua tus muaj nws tus kheej zoo. Hauv cov ntsiab lus txheeb ze, siv cov cib yuav siv sij hawm ntev dua li siv cov khoom siv casting.
