Problems solved by technology

Although this technology is easy to construct and has high bonding strength, its main disadvantages are: first, the cost of mineral raw materials such as coke, kyanite or bauxite clinker is relatively high; Faster, once it meets water or absorbs moisture in the air, it is easy to deteriorate, which is not conducive to the storage of gunning materials; third, CaO in high alumina cement is easy to form a low melting phase with aluminum silicate, which reduces the high temperature performance of gunning materials

Description

technical field [0001] The invention belongs to the technical field of lightweight gunning materials. It specifically relates to an aluminum silicate lightweight gunning material and a preparation method thereof. Background technique [0002] Gunning material is a kind of amorphous refractory material formed by refractory raw materials with a certain particle size distribution, binder and retarder, etc. It is widely used in the construction of high-temperature industrial kilns such as blast furnaces, converters, electric furnaces and cement rotary kilns. with tinkering. [0003] At present, aluminum silicate gunning materials are mainly made of burnt gemstone, kyanite or bauxite clinker as raw materials, alumina micropowder as a burning agent, combined with high alumina cement, and mixed (Wang Xidong, Etc.
