Abstract

The invention relates to a castable, in particular to an explosion-proof castable. The castable is prepared from, by weight, 40-50 parts of first-grade bauxite aggregate, 12-18 parts of first-grade bauxite powder, 15-22 parts of modified vermiculite, 15-18 parts of pearl clay powder, 7-11 parts of cement, 6-12 parts of molybdenum trioxide powder, 6-9 parts of hydrated alumina powder, 4-6 parts ofsilica fume, 2-5 parts of water reducing agent and 1-3 parts of coagulant. The castable has excellent burst resistance.

Description

technical field [0001] The invention relates to castables, in particular to an explosion-proof castable. Background technique [0002] Castable, also known as refractory castable, is a granular and powdery material made of refractory material with a certain amount of binder. It has high fluidity and is an amorphous refractory material formed by casting. Compared with other unshaped refractory materials, the binder and moisture content are higher, and the fluidity is better, so the application range of the castable is wider, and the materials and binders used can be selected according to the conditions of use. It can be directly poured into a lining body, and can also be used as a prefabricated block by pouring or shaking. However, the existing castables often have low explosion-proof performance, which reduces the service life of the castables. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention ...
