High-strength wear-resistant castable for rotary kiln head
The invention discloses a high-strength wear-resistant castable for a kiln head of a rotary kiln. The high-strength wear-resistant castable comprises the following components in percentage by mass: 40-60% of high-alumina bauxite, 10-30% of silicon carbide, 10-20% of high-alumina bauxite powder, 3-7% of pure calcium aluminate cement, 2-7% of silicon dioxide micro powder and 1-6% of active aluminum oxide micro powder. The anti-explosion heat-resistant steel fiber composite material comprises the following components in percentage by weight: 1%-5% of heat-resistant steel fiber, 0.05%-0.5% of organic anti-explosion fiber, 0.05%-0.5% of a composite polycarboxylic acid dispersant, 0.1%-0.5% of a The material disclosed by the invention has the advantages of scouring resistance, good thermal vibration stability, compact structure, stable volume, high strength and long service life, and the service life can reach more than 3 years.
本发明公开了一种回转窑窑头高强耐磨浇注料，其组分以质量百分数计分别为：高铝矾土40%~60%，碳化硅10%~30%、高铝矾土粉10%~20%，纯铝酸钙水泥3%~7%，二氧化硅微粉2%~7%，活性三氧化二铝微粉1%~6%。耐热钢纤维1%~5%，有机防爆纤维0.05%~0.5%，复合聚羧酸分散剂0.05%~0.5%，流动性保持剂0.1%~0.5%，热震稳定剂0.01%~0.5%。该发明的材料具有耐冲刷、热振稳定性好、结构致密、体积稳定、强度高，使用寿命长，使用寿命可达3年以上。
