Microporous corundum castable and production method thereof
The invention discloses a microporous corundum castable and a production method thereof, relates to the technical field of corundum refractory materials, and solves the technical problems of poor thermal shock resistance, large temperature drop and high energy consumption of the traditional corundum castable. Comprising the following components in parts by weight: 65-75 parts of microporous corundum, 8-15 parts of sintered corundum, 6-13 parts of alumina-magnesia spinel, 6-13 parts of activated alumina micro powder, 3-7 parts of pure calcium aluminate cement and 0.5-2 parts of a high-efficiency water reducing agent. The microporous corundum castable prepared by the invention has more excellent thermal shock resistance, the service life of the microporous corundum castable is prolonged, and the safety of the microporous corundum castable is improved; according to the high-temperature furnace body adopting the microporous corundum castable, the heat loss of the high-temperature furnace body can be obviously reduced, and the microporous corundum castable has the advantages of good heat preservation performance, small temperature drop, low energy consumption and cost saving.
