Abstract
The invention provides a production method of deformation-resistant fusion-cast zirconia corundum. The deformation-resistant fusion-cast zirconia corundum is prepared by 20 to 60 percent of clinker and 40 to 80 percent of raw material, wherein the clinker is prepared from the following raw materials: 1.2 to 1.6 percent of sodium oxide, 25 to 33 percent of zirconium oxide, 17 to 19 percent of silicon oxide and 46 to 53 percent of aluminum oxide, and the raw material is prepared from the following raw materials by weight percent: 20 to 50 percent of zircon sand, 38 to 67 percent of calcined aluminum oxide powder, 6 to 20 percent of desilicated zirconia and 1 to 3 percent of sodium carbonate. A main chemical component of the fusion-cast zirconia corundum still belongs to a ternary phase diagram of Al2O3.ZRO2.SiO2, the original advantages of the fusion-cast zirconia corundum brick are sufficiently reserved; and however, by adding main components of baddeleyite and controlling the introduction of impurities, the tensile strength is improved, the deformation rate under the condition of 1500 DEG C can be reduced to 1.2 percent or smaller for 4 hours, the pollution on glass fluid is reduced, the glass quality is improved, and the production method is particularly suitable for producing and manufacturing top-grade glass.
Description
technical field [0001] The invention relates to a refractory material, in particular to a production method of an anti-deformation fused zirconium corundum. Background technique [0002] The upgrading of glass enterprises has strict requirements on zirconium corundum fused bricks. The quality defects of zirconium corundum fused bricks will directly affect the quality of glass products and also affect the service life of glass furnaces. The internal quality of zirconium corundum fused brick usually refers to whether the deformation resistance of the product meets the standard. [0003] Anti-deformation (dynes / cm 2 ) refers to the deformation index when the material bears the maximum force before breaking. When the refractory material yields to a certain extent, due to the rearrangement of the internal grains, its resistance to deformation is improved again. Although the deformation develops rapidly at this time, it can only increase with the increase of stress until the str...
