Problems solved by technology

[0003] However, during the firing process of the zirconium corundum composite brick in the prior art, the bonding strength between materials is low, the compactness is poor, and the pores are high, resulting in poor thermal shock stability of the composite brick and unsatisfactory slag erosion resistance; at the same time , during the preparation process of zirconium corundum composite bricks in the prior art, the internal stress of the brick body is relatively large, which easily causes the brick body to crack

Abstract

The invention discloses a wear-resistant and anti-corrosion composite brick of zirconium corundum and its production process. The composite brick includes the following raw materials: ZrSiO 4 、Al 2 o 3 、Al 2 (SiO 4 )O, MgCO 3 , Fe 2 o 3 , Sb 2 o 3 、Cr 2 o 3 、TiO 2 , MnO, CuO, Na 2 CO 3 , kaolin, epoxy resin, composite binder, water reducing agent and binding agent; the preparation method of the composite brick is: first weigh the raw materials, and pulverize and mix, then mix the pulverized material with water, and grind and dry After processing, add epoxy resin, composite binder, water reducer and binder to the ground material, stir evenly, and finally press the mixed material into shape, dry and fire to obtain the finished composite brick; The composite brick prepared by the invention has higher compactness and bonding strength, stronger slag erosion resistance, and is suitable for mass promotion.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a wear-resistant and corrosion-resistant composite brick of zirconium corundum and a production process thereof. Background technique [0002] At present, refractory materials for incineration systems in the hazardous waste disposal industry are mostly made of refractory bricks made of corundum, chrome corundum, zirconium corundum and other materials. These bricks have refractory properties, high load softening temperature, wear resistance, chemical stability, thermal It has the advantages of good shock stability and slag erosion resistance, which can increase the service life of the incinerator, increase productivity and reduce production costs. Fused-cast zirconium corundum materials are widely used in the lining of the upper structure of the furnace, which can increase the life of the furnace and meet the requirements of glass melting and clarification temperature...
