Problems solved by technology

At present, mullite refractory castables are used in this field. The disadvantages are that the wear resistance is poor, the service life is relatively short, and the thermomechanical and chemical erosion effects on high-temperature clinker are relatively weak. It is urgent to develop a high-temperature-resistant, high-temperature Wear-resistant, high-alkali-resistant new materials to meet the performance requirements of this part

Abstract

The invention provides a casting material with high temperature resistance, high abrasion resistance and high alkali corrosion resistance for a calcining kiln with respective to shortcomings in the prior art, and further aims to provide a preparation method for the casting material. The technical scheme is that the casting material is characterized by consisting of the following components in percentage by weight: 1 percent of Taiyuan purple flower waste rock, 17 to 22 percent of calcium chromate, 17 to 19 percent of silicon carbide, 28 to 30 percent of ferrochrome slag, 5 to 10 percent of zinc ferrite, 5 to 8 percent of magnesia-zirconia olivine, 1 to 3 percent of magnesium potassium titanate, 1 to 2 percent of zirconium aluminium nitride, 3 to 5 percent of merwinite, 5 to 10 percent of alumina micro powder, 2 to 3 percent of calcium aluminium zirconate, 3 to 5 percent of high-alumina cement, and 0.5 percent of Ti3SiC2, 0.1 percent of methyl allyl alcohol polyoxyethylene ether, 0.05 percent of prenyl alcohol polyoxyethylene ether, 0.1 percent of aluminium potassium sulfate dodecahydrate, and 0.05 percent of potassium chromium alum dodecahydrate.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a casting material for a calcining kiln and a preparation method thereof. Background technique [0002] At present, my country's new dry process cement production line is developing rapidly, and the cement production capacity has been severely oversupplied. Therefore, it is the only way for cement production enterprises to increase unit production efficiency and reduce production costs to maximize profits. And improving the operation rate of the cement production line is an important condition for improving the production efficiency of the cement kiln. However, the life of the grate cooler wall of the cement calcining kiln has an important influence on the operation cycle of the entire production line. The grate cooler wall of the cement kiln is used in harsh conditions. In addition to high temperature, it also bears the continuous discharge pressure of the cemen...
