High alumina refractory cibrau blast furnace yog cov khoom siv refractory ua los ntawm siab alumina bauxite clinker nrog Al ₂ O Ⅲ cov ntsiab lus ntau dua 48%. Nws yog tsuas yog siv rau qhov qis dua ntawm lub qhov cub tawg lub cev. Cov khoom no muaj qhov kub thiab txias tsis kam thiab yaig tsis kam, nrog rau qhov kub thiab txias ntawm 1580-1770 degree.
Blast furnace yog cov cuab yeej tseem ceeb rau kev ua hlau, thiab cov av nplaum cib yog cov khoom siv thaum ntxov tshaj plaws uas siv rau hauv qhov cub tawg. Txij li thaum xyoo 1950, lub peev xwm ntawm qhov cub tawg tau tsim los ntawm qhov loj dua, thiab 8-12m txoj kab uas hla ntawm lub cub tawg tau ua ntau dua. Kev loj hlob sai ntawm kev tsim khoom. Txawm li cas los xij, qhov yaig ntawm lub duav lub duav thiab lub plab ua rau muaj kev cuam tshuam rau kev tsim cov blast furnaces.
Thaum ntxov 1960s. Tebchaws Asmeskas tau pib siv cov pob zeb alumina siab uas muaj 90% Al2O3 hauv qhov cub tawg rau kev tsim cov ferromanganese. Thaum xyoo 1960s lig, kev siv slag resistant, tsis oxidizing, thiab hnav-resistant fused alumina cib nrog ntau dua Al2O3 cov ntsiab lus, spinel cib uas muaj chromium oxide thiab fused magnesia chrome xuab zeb, thiab fused alumina cib tau tsim. Thaum ntxov xyoo 1970, Nyiv thiab Tebchaws Meskas twb tau siv cov khoom siv silicon carbide series nrog kev ua tau zoo dua li cov saum toj no -cov cib tau hais, lossi nrhiav kev zoo tshaj plaws thiab ruaj khov hauv ob sab phlu rau blast furnace txhawb kev ua haujlwm smelting.
Tuam Tshoj tau pib tsim cov alumina cib siab rau lub tshuab hluav taws xob tawg thaum xyoo 1950s los siv rau hauv qab ntawm lub qhov cub lub cev. Txij li thaum xyoo 1980s, hluav taws xob fused alumina composite cib tau siv, nrog rau Al2O3 cov ntsiab lus ntawm ntau dua 95% thiab siab -kub load softening kub (T2) ntawm 1740-1770℃. Tom qab tuav ntawm 1600℃rau 3 teev, qhov shrinkage tus nqi ntawm re raug rho tawm haujlwm yog xoom. Xyoo 1984, cov khoom siv silicon carbide series tau ua tiav thiab maj mam tsim cov peev txheej ntau lawm. Cov khoom siv tau siv nyob rau hauv qis qis ntawm lub tshuab hluav taws xob tawg.
Kev ua tau zoo ntawm Tuam Tshoj blast furnace siab alumina cib tau muab faib ua peb qib raws li Al2O3 cov ntsiab lus: GL-48, GL-55, thiab GL-65, nrog cov qauv cib tsim.
