Refractory Castables for Different Parts of Cement Kilns

Refractory castables for kiln mouth

Due to the high temperature, heavy wear and harsh working conditions at the kiln mouth, it is recommended to use corundum refractory castables, high-performance kiln mouth-specific refractory castables or improved kiln mouth-specific castables.

Refractory castables for burners

The working environment of the burner is around 1400°C, its flame temperature is around 2000°C, and it works in an alkaline atmosphere for a long time. The temperature changes more frequently and the temperature difference is large. The front end of the burner is always washed by high-temperature airflow carrying clinker dust, especially the lower part, so the refractory castable for burner needs to have sufficient wear resistance,good thermal shock resistance and good alkali resistance.

It is recommended to use special castables for burners . This product has excellent peeling resistance and thermal shock resistance.

Refractory castables for kiln head cover and grate cooler

It is recommended that these two parts use high-strength wear-resistant castables and erosion-resistant castables with good high-temperature performance, strong thermal shock resistance, and wear resistance.

Refractory castables for tertiary air duct elbows and air valves

This part changes greatly in heat and cold, and is washed away by high-temperature clinker particles. The castables are prone to loosening, peeling, etc.It is recommended to use wear-resistant refractory castables and special wear-resistant castables.
Refractory castables for C4 and C5 cones and their feeding pipes, decomposition furnace cones and smoke chambers
The above-mentione.d parts are very easy to crust and are difficult to clean off. Once severe crusting occurs, the kiln needs to be stopped for processing. It is recommended to use silicon carbide anti-scaling high-strength castable.

Refractory castables for other parts

It is recommended that C1~C3 use high-strength and alkali-resistant castables, C4 and C5 (except the cone part) use high-temperature and high-strength alkali-resistant castables, and the decomposition furnace uses high-strength and wear-resistant castables.
