Abstract

The invention provides a waste medical incinerator lining anti-erosion refractory castable and a preparation method thereof, and relates to the technical field of refractory castable, The waste medical incinerator lining anti-erosion refractory castable and the preparation method thereof comprise the following raw materials by weight: 80-100 parts of brown fused alumina, 20-30 parts of periclase, 5-10 parts of silica, and 15-25 parts of calcium silicate cement. The preparation method comprises the following steps: respectively crushing the brown fused alumina, periclase, silica, calcium silicate and calcium aluminoferrite into powder according to the weight ratio, and uniformly mixing to obtain the refractory castable; the refractory castable prepared by the invention is located in a severe environment of the same incinerator, the erosion area is small, the erosion depth is shallow, and the prepared refractory castable has a strong anti-erosion effect.

Description

technical field [0001] The invention relates to the technical field of refractory castable production, in particular to an anti-corrosion refractory castable for waste medical incinerator lining and a preparation method thereof. Background technique [0002] The incinerator is a kind of harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. The incinerator has a huge volume and a correspondingly large weight; during the incineration process of waste, the temperature generated is too high , can reach a high temperature of 1200 ° C, and the refractory structure set in the furnace is made of refractory materials. [0003] A preparation method of a refractory castable is disclosed in the Chinese patent whose authorized notification number is CN102718512B. The raw material composition and weight ratio of the refractory castable are: a thermal shock resistant corundum-spinel refractory castable, which The ratio of raw mater...
