The coke oven door is frequently opened during production, the surface temperature is high, and the coke temperature changes greatly. Cordierite brick and clay brick are used in the lining of traditional coke oven door in China, but the service cycle is not long.

While the properties of composite refractory castable can be used, it can be made into prefabricated blocks, which is convenient for construction and has a long service cycle. Therefore, the use of clay and fused quartz composite refractory castable is most suitable for the use of coke oven doors.

After the castable is added with retarding agent, it cannot be used without fluidity, because the castable has difficulty condensing without fluidity, which seriously affects the strength of the castable.

High alumina brick is a kind of middle grade Fire brick among the stereotyped products of refractory materials. It belongs to neutral refractory materials and is used in the lining of industrial kilns.

Clay bricks quality is different indifferent area in China due to the local raw materials level, for example of the clay bricks in Henan, the aluminum content is high and more purity, the body is dense, and the use effect is almost the same as the general three-level high aluminum bricks.

Feeding damage is due to the damage generated when feeding to the intermediate frequency furnace, mainly because some large raw materials did not pay attention to when adding, so that large raw materials from high to add, causing damage to the furnace lining. When feeding, pay attention to the height of the raw material falling, can avoid this damage, at the same time, when adding pieces of block material, need to pay attention to prevent the furnace lining to scratch.

As we all know, induction furnace ramming material has a wide range of application, whether it is cast iron, cast steel, cast copper, nodular cast iron, gray iron, plain carbon steel
