Wear-Resistant Castables Used in Cement Plants

The wear-resistant castable materials used in cement plants have the characteristics of good volume stability, high strength, good wear resistance, and thermal shock resistance. The wear-resistant castable materials used in cement plants are mainly used in the front of the burner of the cement kiln because this part is in the kiln. It is always scoured by the airflow, especially the lower part is more severely scoured.

Wear-resistant castables for cement plants are mainly made of high-strength refractory materials such as special grade alumina, corundum and silicon carbide as aggregates and fine powders, with fine powder added. The material has the characteristics of good volume stability, high strength, good wear resistance, thermal shock resistance, corrosion resistance, no cracking, no peeling, etc. The products are mainly used for the severe erosion and abrasion parts of industrial kilns such as ball rotary kilns and coal injection pipes.

Wear-resistant castables for cement plants are mainly used in the front end of the cement kiln burner. This part is always washed by airflow in the kiln, especially the lower part is more severely washed, and the airflow clamps the clinker dust in the kiln. The impact on the front end of the burner causes strong erosion and wear, thereby reducing the service life of the equipment; at the top of the kiln head cover near the tertiary air duct, the dust airflow is relatively serious; the top of the grate cooler is not only affected by the rebound thermal shock of the clinker , The working temperature is relatively high, and the change is large. The low walls on both sides of the front end of the grate cooler have long passed the high temperature clinker down the kiln mouth, and they are damaged by certain mechanical and thermal stress; there is also the bending of the tertiary duct It is also easier to wear under the scouring of dust airflow. Therefore, materials with good wear resistance and fire resistance should be used in these parts, and in order to facilitate construction, wear resistance and refractory castables should be used.

The use of wear-resistant castables in cement plants as lining materials for cement kilns has received full attention. New dry-process cement kilns use more refractory materials. Different specifications of cement kilns and different use parts of the system have different refractory materials. It is necessary to select the suitable varieties when designing the matching requirements.

The thermal conductivity of the wear-resistant castable directly determines its use, and also affects its thermal shock resistance, peeling resistance and erosion resistance. There are many factors that affect the thermal conductivity of high-strength wear-resistant castables, and they are also very complex. First of all, the thermal conductivity of a material is closely related to its chemical composition, mineral composition, density, and microstructure. The thermal conductivity of high-strength wear-resistant castables with different chemical compositions is also different. The more complex the chemical composition of high-strength wear-resistant castables, the more obvious the decrease in thermal conductivity.
