Abstract

The invention discloses a zircon self-flowing castable. The zircon self-flowing castable is characterized by comprising aggregate, powder and an admixture, the aggregate is prepared from high-aluminabauxite clinker, sub-white corundum, zirconite and baddeleyite which account for 70-80% of the sum of the mass of the aggregate and the mass of the powder; the powder comprises silica powder accounting for 1-6% of the sum of the mass of the aggregate and the powder, sub-white corundum powder accounting for 1-10% of the sum of the mass of the aggregate and the powder, alumina powder accounting for1-12% of the sum of the mass of the aggregate and the powder, zirconia powder accounting for 2-3% of the sum of the mass of the aggregate and the powder, white mud accounting for 1-10% of the sum of the aggregate and powder, high-alumina bauxite clinker accounting for 0-25% of the sum of agrregate and the power, the mass of the high-alumina cement accounting for 0-3% of the total mass of the aggregate and the powder, and the mass of the pure calcium aluminate cement accounting for 0-6% of the total mass of the aggregate and the powder. The zirconium self-flowing castable is stable in propertyand performance at high temperature and excellent in fire resistance, the cracking resistance can be improved by 2%-3% of zirconium oxide powder, and the fire resistance is integrally improved.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a zirconium self-flowing castable. Background technique [0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output; in th...
