High-strength anti-erosion chute prefabricated part for copper smelting and preparation method of high-strength anti-erosion chute prefabricated part

Abstract

The invention relates to the technical field of refractory materials for copper smelting, and discloses a high-strength anti-erosion chute prefabricated part for copper smelting and a preparation method thereof.The high-strength anti-erosion chute prefabricated part for copper smelting is prepared from, by mass, 60-80 parts of high bauxite, 10-15 parts of corundum, 5-10 parts of modified silicon carbide, 3-5 parts of reinforcing filler, 8-10 parts of ultrafine powder, 6-10 parts of cement, 0.2-0.5 part of additive and 50-60 parts of deionized water. The cobalt silicate layer is synthesized on the surface of the silicon carbide in situ, the contact area between the silicon carbide and raw materials of the chute prefabricated part is increased, the compact chute prefabricated part can be formed, and the situation that the mechanical performance of the chute prefabricated part is reduced and the strength and erosion resistance of the chute prefabricated part are reduced due to the fact that the silicon carbide is prone to swelling deformation at high temperature is prevented. The nano aluminum oxide has excellent metal solution penetration resistance, and the compound clay has low permeability, so that the erosion resistance of the chute prefabricated part is enhanced, and the chute prefabricated part shows excellent mechanical performance.
