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.
