Calcium aluminate cement-combined corundum castable and preparation method thereof
The invention discloses calcium aluminate cement-combined corundum castable and a preparation method thereof. With calcium aluminate cement as a binding agent, tabular corundum and activated aluminum oxide as main components, and titanium dioxide/calcium carbonate/magnesium oxide micro-powder as a compound additive, the high-strength calcium aluminate cement-combined corundum castable is prepared. By combining with the characteristics of accelerating sintering by virtue of titanium dioxide and forming spinel and calcium carbonate to convert into high-activity calcium oxide at a high temperature by reaction of magnesium oxide and corundum, the strength of the corundum castable is greatly improved. The prepared high-strength calcium aluminate cement-combined corundum castable has excellent performance, and can be applicable to the industries such as building materials, metallurgy and petrifaction; and the service life of equipment such as a cement kiln opening, a coal-injection duct, an induction furnace lining and a high-temperature wear-resisting lining is effectively prolonged.
