Mullite Refractory Brick for Anode Carbon Furnace
The Description:
Anode baking furnace is one of the important equipment in the anode roasting process, and it is also the most expensive equipment in the whole roasting process. The anode baking furnace is made of different kinds of refractory materials, of which the most important part is the material box structure composed of the fire passage wall and the cross wall, the anode carbon block is installed in the material box in turn, the fuel is injected into the fire passage, the highest flue gas temperature in the fire passage is 1150ºC~1200ºC, and the heating curve is 150h~200h. The whole roasting system is divided into preheating zone, heating zone and cooling zone, and in each roasting cycle, the refractory will experience the temperature change from low temperature to high temperature, and from high temperature to low temperature, which puts forward more stringent requirements for the performance of refractory materials

Product feature:
Good quality refractory brick, with higher refractoriness and load softening temperature, low line variability at high temperature, better resistance to acute cold and heat, in the normal use process, can resist high temperature erosion and waste gas generated by fuel combustion acid and alkaline atmosphere erosion. The refractory brick is located in the high-temperature part of the baking furnace, which is in direct contact with the flame and the product, and is the most important refractory material of the baking furnace. Good refractory brick will greatly improve the overall performance of the baking furnace, which will be of great significance to the production operation.
