Abstract

The invention discloses a zero-baking castable which is prepared from the raw materials including, by weight, 55-70 parts of a high-aluminum aggregate, 15-20 parts of high-aluminum fine powder, 2-6 parts of aluminum oxide micro-powder, 2-6 parts of silicon micro-powder, 0.5-3 parts of calcium aluminate cement, 0.03-0.2 parts of sodium tripolyphosphate, and 0.2-0.8 parts of a comprehensive explosion-proof agent which is prepared from the raw materials including, by weight, 5-10 parts of aluminum powder in 200 meshes, 10-15 parts of aluminum powder in 100 meshes, 5-8 parts of aluminum powder in 40 meshes, 8-12 parts of basic aluminum lactate, 5-8 parts of azodicarbonamide and 20-30 parts of water-soluble fiber at 60 DEG C. The zero-baking castable is free of maintenance and furnace baking, can be applied directly, can save the cost of furnace baking and can save the time of maintenance and furnace baking.

Description

technical field [0001] The invention relates to the technical field of non-metallic refractory materials, in particular to a zero-baking casting material. Background technique [0002] After the construction of the castable is completed, necessary maintenance and baking work is required. Insufficient curing time affects the strength of the castable. Insufficient baking time or careless operation during baking will cause serious quality accidents such as cracks, bursts, falling blocks or even collapses during the baking of the castable or after it is put into use. Therefore, the user unit of the castable will give the castable a minimum of 3 days of curing time after the construction of the castable, and a baking time of 5 to 20 days depending on the size of the castable. In furnace building, refractory materials and other books and actual work, the information we have obtained is that the maintenance and baking of castables are necessary, and the baking must be treated seri...
