Vim li cas Siv Tabular Alumina hauv Steel Ladle Slide Gates?

Swb lub rooj vag li qub nyob rau hauv niaj hnub steelmaking nroj tsuag kov cov kua steel kub tshaj 1600℃thaum tiv taus siab mechanical siab thiab molten hlau scouring. Ua haujlwm ua tus thawj sib sau ua ke hauv siab -kev ua tau zoo alumina-carbon swb rooj vag daim hlau, tabular alumina yog tsim los ntawm sintering ntshiab alpha alumina ntawm qhov kub siab tshaj 1900℃yam tsis muaj additives. Nws cov ntsiav tshuaj loj, tiaj tus- zoo li cov khoom siv lead ua muaj kaw micro- qhov hws, muab cov thermal poob siab zoo tshaj plaws uas tiv thaiv cov ntawv swb los ntawm kev tawg thaum lub sij hawm kub hloov pauv thaum cov hlau pib pib.

Tshuaj purity thiab particle sib xws ncaj qha txiav txim siab corrosion kuj thiab kev pab cuam lub neej ntawm zawv zawg mechanism.HUAOtabular alumina nta siab Al₂O₃ cov ntsiab lus (Ntau dua lossis sib npaug li 99.2%) thiab ultra-Na₂O qib qis (tsawg dua lossis sib npaug li 0.40%), uas txo qis cov kua theem tsim ntawm qhov kub siab. Cov ntxhib thiab nruab nrab nplej tiv thaiv tshuaj tua kab mob los ntawm kev txhoj puab heev hlau alloys thiab hluavtaws slags, khaws cia tiaj tus chaw sib cuag thiab tiv thaiv molten steel to. Los ntawm kev tswj xyuas qhov kev xav tau ntawm cov khoom ntim khoom siv thaum lub sij hawm tsim cov khoom siv refractory, steel mills txo qhov kev pheej hmoo ntawm cov phaj tsis ua hauj lwm, ua tiav cov txheej txheem txuas ntxiv, thiab kev ua haujlwm qis dua.
