Refractory spray coating repair technology

The main reason for the damage of the refractory spray coating is that it has been affected by erosion, erosion, wear and other problems, and the damage must be repaired in a timely manner. This repair technology is also a science. If there is no special training, it can not be repaired. Let me teach you Material repair technology:
1.The insulation layer is damaged
The heat insulation layer is an inner lining to avoid the heat loss of the high temperature kiln. Generally, heat insulation fiber material products with low thermal conductivity and lightweight heat insulation bricks are selected. After the heat insulation layer is damaged, it can be repaired with heat insulation spray coating to increase insulation. Thermal effects to avoid affecting thermal cycling.
2. The gap is damaged
It is very common for cracks and air leaks to appear in the gaps. If they occur, we can use low temperature infusion or refractory pressure infeed, and use air compressors to squeeze the refractory to the damaged place. After sintering at high temperature, it can quickly form a whole.
3.The high temperature furnace lining is damaged
① First judge according to the damage situation. For simple damage, spray or spray repair technology can be selected.
② If the hot repair material is produced, it can be repaired by mechanical control repair equipment while the kiln is running.
③ If the damage is serious, the inner lining can be removed, and appropriate refractory materials should be used for construction and installation.
Due to the different damage of the refractory spray paint, its repair methods are different, so we will use different repair materials for different parts in the future, and choose targeted repair technologies and methods to repair quickly without delaying our use.
