Novel furnace wall repairing process
The invention belongs to the technical field of ring furnace wall repairing, and particularly relates to a novel furnace wall repairing process. The novel furnace wall repairing process comprises the steps of cleaning the surface of a refractory brick, welding a steel plate, filling a furnace wall crack repairing material, pasting a heat preservation and insulation material and the like. According to the novel furnace wall repairing process, mixed slurry of aluminum dihydrogen phosphate and refractory mortar is adopted as the repairing material, the stability at high temperature is superior to that of independently-used refractory mortar, through multi-round operation of a ring furnace, the crack state repaired by using the aluminum dihydrogen phosphate mixed refractory mortar is intact, repairing does not need to be conducted again, the workload of workers can be reduced, and the cost can be reduced.
本发明公开的属于环式炉炉墙修复技术领域，具体为一种新式炉墙修复工艺，包括对耐火砖表面清理、焊接钢板、填充炉墙裂纹修复料、贴保温隔热材料等多个步骤，本发明采用了磷酸二氢铝与耐火泥浆的混合泥浆作为修复料，在高温下的稳定性要优于单独使用耐火泥，经过环式炉的多轮运行，使用磷酸二氢铝混合耐火泥修补的裂纹状态完好，无需再次修补，可减轻工人的工作量并可减少成本。
