Corundum brick for hazardous waste rotary kiln and preparation method thereof
The invention discloses a corundum brick for a hazardous waste rotary kiln, which comprises the following components in percentage by mass: 85-90% of corundum, 3-8% of alumina micro powder, 0.1-0.3% of an activating agent and 3-8% of pure calcium aluminate cement. The invention further provides a preparation method of the corundum brick for a hazardous waste rotary kiln. The activating agent is added into the raw materials, so that the fluidity of the mixture is improved. The corundum brick is formed through a vibration table in a pouring forming mode in the later period, the compactness of the corundum brick is improved, the thermal stress of the brick is reduced, cracking is not likely to happen, and the anti-erosion effect is good.
本发明公开了一种危废回转窑用刚玉砖，包括以下质量分数的组分，刚玉85~90%，氧化铝微粉3~8%，活化剂0.1~0.3%，纯铝酸钙水泥3~8%。本发明还提供了一种危废回转窑用刚玉砖的制备方法。本发明通过在原料中加入活化剂增加了混合料的流动性，后期又采用振动台浇筑成型的方式成型，增加了刚玉砖的致密性，减少了砖的热应力，不容易开裂，抗侵蚀效果好。
