Embodiment 1
[0028] 90 parts of fused chromium corundum and 5 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry blend in a wet mill. After the particles and fine powder are mixed evenly, add 90 parts of fused chromium corundum and 5 parts A mixture of white aleurone blended liquid and water with a mass ratio of 7:3 is pressed at a pressure of 400T to form brick adobes, and the resulting brick adobes are placed in a dryer and dried at 200°C for 48 hours.
Embodiment 2
[0030] 92 parts of fused chromium corundum and 6 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry mix in a wet mill, and after the particles and fine powder are mixed evenly, add 5 parts with a mass ratio of 7:3 The mixture binder of white aleur powder blending liquid and water is pressed at a pressure of 480T to form brick adobes, and the obtained brick adobes are placed in a dryer and dried for 48 hours at a temperature of 250°C.
Embodiment 3
[0032] 94 parts of fused chromium corundum and 7 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry blend in a wet mill, and after the particles and fine powder are mixed evenly, add 5.5 parts. The mass ratio is 7:3 The mixture binder of white aleur powder blending liquid and water is pressed at a pressure of 500T to form brick adobes, and the obtained adobes are placed in a dryer and dried at a temperature of 240°C for 48 hours.
