高附着性钢包包壁冷态整体修补料
摘要：
本发明公开了一种高附着性钢包包壁冷态整体修补料，各组分的重量百分含量为：特优矾土颗粒35~45%，刚玉颗粒和刚玉细粉35~45%，电熔镁砂细粉5~15%，α-Al2O3微粉2~12%，硅灰1~5%，外加剂0.1~0.5%；所述的外加剂为高效减水剂，所述的特优矾土颗粒是由特优矾土经过破碎和筛分设备加工成5~3mm和3~1mm两个粒级，所述的刚玉颗粒由3—1mm、1—0mm的刚玉物料构成，所述的刚玉细粉的粒度为0.088—0mm，刚玉颗粒与刚玉细粉的比例范围为1：（1.8~2.2）。本发明生产的钢包包壁冷态整体修补料在现场的实际应用表明，由于反弹少，附着性能好，烘烤后几乎无脱落，对提高钢包衬使用寿命效果显著，经济效益明显；另外由于烘烤后几乎无脱落，大大增加了钢包使用过程的安全性。
摘要（英）：

The invention discloses a cold state integral repairing material with high adhesiveness for a wall of a steel ladle. The material comprises the components in percentage by weight as follows: 35-45% of extra-superior alumina particles, 35-45% of corundum particles and fine powder, 5-15% of fused magnesite fine powder, 2-12% of alpha-Al2O3 micro-powder, 1-5% of silica fume and 0.1-0.5% of additive. The additive is an efficient water reducer. The extra-superior alumina particles are processed by extra-superior alumina which is processed to 5-3mm and 3-1mm grades by a crushing and screening device. The corundum particles consist of 3-1mm and 1-0mm corundum materials. The granularity of the corundum fine powder is 0.088-0mm. The proportional region of the corundum particles to corundum fine powder is 1: (1.8-2.2). Field actual application of the cold state integral repairing material with high adhesiveness for the wall of the steel ladle shows that the material is good in adhesiveness due to less bounce, nearly free from falling after being roasted, remarkable in effect of prolonging the service life of the steel ladle liner and remarkable in economic benefit. In addition, the material is nearly free from falling after being roasted, so that the safety of the steel lade during use is greatly improved.
