Abstract

The invention discloses a high-strength alkali-resistant refractory castable, including refractory aggregate, powder, binder, additive and water. Waste electroceramics and waste tiles are processed into a refractory aggregate of 1-5mm; chamotte, waste electroceramics, waste tiles, mullite and silicon powder are mixed and processed into a powder; and binder and additive are added into the refractory aggregate and the powder. The invention selects waste electroceramics and waste tiles with excellent alkali resistance to produce a castable with excellent alkali resistance; the waste electroceramics and the waste tiles has characteristics of wide source, large quantity and no environmental pollution, so as to reduce costs on raw material consumption and harm to the environment, and realize abundant raw material, energy saving and environmental protection. The mullite powder and silicon powder fill gaps of the castable, and improve the casting material pressure resistance and bending strength; and chamotte and CA50-G6 cement better bond the refractory aggregate and the powder.

Description

【Technical field】 [0001] The invention relates to a refractory castable, in particular to an energy-saving and environment-friendly high-strength alkali-resistant refractory castable. 【Background technique】 [0002] Refractory castables are the main varieties of unshaped refractory materials, mainly used in the production of cement materials, and also used in metallurgical industrial kilns, petroleum, chemical, building materials, electric power, mechanical industrial kilns and thermal equipment. Castables are generally composed of refractory aggregates, powders, binders, admixtures, and solvents. The raw materials of refractory aggregates are generally magnesia, stone dome, perlite, spinel, etc. Refractory castables are poured, vibrated or tamped into shape, and can be hardened without heating. They are widely used for their convenient construction and high utilization rate. The current castables have low alkali resistance, consume a lot of raw materials, and have high pro...
