Corundum Combined Prefabricated Refractory Products for Coke Oven
The Description:
Due to the uniform size of the general refractory brick, the process of masonry installation in the kiln is complicated, there are many gaps, and the material selection is unreasonable. In the actual application of some thermal equipment, there will be the effect of mechanical external force, resulting in the fracture of refractory masonry, falling off and other phenomena. Due to the poor overall performance of the shaping material, fire leakage, air leakage, furnace lining collapse and so on occur. The prefabricated blocks and prefabricated parts can be produced according to the actual size of the kiln, which ensures the integrity of the furnace lining material and effectively reduces the gap of the furnace lining. Moreover, the thermal shock damage caused by the fluctuation of furnace temperature is effectively reduced due to the characteristics of prefabricated blocks and prefabricated parts.

The Advantage:
1) Low porosity, low hot-wire expansion rate, good thermal shock stability. Can fully meet the needs of coke oven door;
2) Easy to use, can quickly disassemble the furnace door, reduce the time wasted due to maintenance;
3) Reduce the heat loss caused by the loosely sealed furnace door and save energy:
4) Basically eliminate the air pollution caused by the furnace door is not strict, and achieve environmental protection.
