High Abrasion Resistance and Anti-erosioAn Casting Material

The High Strength and Wear-resisting Casting Material

High abrasion resistance and anti-erosion casting material

This company produces the high strength wear resistant erosion resistant castable, it contains the following weight percentage composition, particle size 1-3 mm respectively, 3-5 mm, 5-8 mm, 8-12 mm, white corundum as aggregate particles, the total weight percentage of 30-40%;Silicon carbide powder + alumina micro powder accounted for 50-60%;Steel fiber accounts for 1-2%;The porcelain powder is 3-5%, and the porcelain powder includes 20-80 quality SiO2 and 10-50 quality AlF3.Potassium feldspar 3-5%;The combination of sodium tripolyphosphate and 7-10% of the total weight of the above components is 0.15-0.20%.The invention in view of the special working conditions of parts of the cement kiln, by studying the damage mechanism of the three duct parts material, developed and become a kind of high performance of chemical combination of abrasion resistance to erosion of the castable.The product will gradually take chemical reaction in the process of use, which has the characteristics of high wear resistance, good acid resistance and long term.The pouring material is convenient and fast, and the combination agent can be used in the field, and it can be used for the use of simple curing, and the average service life is more than two years.

Wear-resistant refractory castable used parts such as: power plant boiler and circulating fluidized bed boiler, pulverized coal furnace, garbage incinerator, waste heat boiler, the chain furnace arch before and after the nose section bend easily worn parts, etc.The material is mainly used in the combination of high aluminum homogenization and corundum and silicon carbide, and the blue crystal powder is added as the expansion agent, and the combined agent is calcium aluminate cement.
