zircon corundum block yog tsim nrog ruaj khov zircon xuab zeb thiab tshaj 64% zircon ntsiab lus. zircon corundum hluav taws thaiv yog poured rau hauv pwm tom qab melted nyob rau hauv hluav taws xob melting rauv. Cov qauv lithofacies muaj eutectoid thiab iav theem ntawm corundum thiab zirconium plagioclase. zircon corundum refractory block petrographic qauv yog ua los ntawm eutectoid thiab iav theem ntawm corundum thiab zirconium clinopyroxene. zircon corundum blocks muaj cov yam ntxwv ntawm lub zog txhua yam, zoo thermal poob siab tsis kam, siab refractoriness nyob rau hauv load, muaj zog yaig kuj thiab siab ceev.
Zirconia corundum cib nyiam proportions ntawm 1: 1 zircon xuab zeb thiab muaj alumina hmoov thiab ntxiv ob peb ntim ntawm NaZO, B20 tus neeg sawv cev ntawm fusion tom qab sib tov zoo kawg nkaus los ntawm smelting thiab pouring rau hauv pwm ntawm kub ntawm 1900 ~ 2000 ℃ ua rau fused cam khwb cia bricks muaj 33 % ZrO2 cov ntsiab lus. Nyob rau hauv lub hauv paus, txais yuav ib feem ntawm desilication zircon xuab zeb ua raw khoom los ua fused cam khwb cia cib nrog 36% ~ 41% ZrO2 cov ntsiab lus.
UAS-33
AZS33 zirconia corundum cib ntom ntom microstructure ua rau cov iav resistant rau iav yaig kev ua tau zoo tsis yooj yim los tsim pob zeb lossis lwm yam tsis xws luag, thiab muaj peev xwm tsim cov npuas me me yog tsawg heev.
UAS-36
Ntxiv rau qhov zoo ib yam li AZS-33 zirconia corundum firebrick, AZS-36 zirconia corundum cib vim qhov sib ntxiv ntawm ntau cov saw zoo li zirconia muaju, thiab cov ntsiab lus iav poob.
UAS-41
AZS-41 zirconia corundum hluav taws cib muaj ntau yam kev faib tawm ntawm zirconia crystals, nyob rau hauv zirconia corundum series, nws yaig kuj yog qhov zoo tshaj plaws.

Zircon corundum blocks feem ntau yog siv rau hauv iav kev lag luam rauv, iav hluav taws xob rauv, slideway kiln ntawm hlau thiab hlau kev lag luam, sodium metasilicate muaj rauv rau tiv thaiv cov tshuaj thiab cov neeg kho tshuab yaig ntawm qhov kub thiab txias.
