Wear Resistant Refractory Castable is a kind of refractory castable that is resistant to high temperature solid materials or airflow with solid power. It is made of high hardness and high density aggregate, composite powder and special additive. It has the features of high density, high strength, wear and erosion resistance, volume stability, suitable for erosive-wear parts of the circulating fluidized bed boiler. It can be used as the high temperature wear resistance, and erosion resistance lining, such as the circulating fluidized bed lining, and the steel tank lining.

What is Wear Resistant Refractory Castable
Wear-resistant refractory castable is main varieties of monolithic refractory. Because of its high flexural strength, wear resistant castable is also called high strength refractory castable. It is abrasion resistant, and especially suitable for harsh conditions that the other refractories can’t bear. Because of the composite binder with good combined performance, wear-resistant refractory castable has good bonding performance with other materials. It can be used as the single lining, double lining, and thermal insulation wear-resisting lining. And it also can be used as the repairing mix.In addition it has characteristics of good construction performance, easy maintenance, fast curing performance at room temperature.
Properties of Wear Resistant Refractory Castable
The reasons that wear resistant refractory castable is different from others refractory materials are as follows:
Properties and Advantages
It cures very fast at room temperature, about 4 to 8 hours. 24 hours after curing it begins for the use of the furnace. In addition, its curing rate can be adjusted according to the construction requirements.
It keeps high strength and high wear resistance in the process of heating and using.
Good construction performance and easy construction save the construction period, save time, save money and save manpower.
Easy maintenance without water.
Wear resistant refractory castable is suitable for the cement kiln burner front end that is impacted by airflow constantly, especially the lower part. In the airflow, there are many dust of clinker from the stove, which can cause strong erosion by striking the front end of the burner, thereby reducing the service life of equipment.
Continual thermal shock of the clinker, relatively high working temperature and mechanical pressure at the top front end of the grate cooler, both sides of the grate cooler in the front is easy to wear. So wear resistant refractory castable should be used in these in these parts.
Wear resistant refractory castable can be used in the following parts:
Uses and Applications
The inner lining of the circulating fluidized bed boiler;
The furnace lining of steel tank of the heating furnace;
Separator and imports,furnace of garbage incinerator;
Water-cooled screen, heat treatment furnace;
High temperature cyclone separator, double slide valve, rising pipe, etc.
High temperature hot blast pipe lining, and flue lining;
Furnace of chemical industry and construction industry, etc.
You can buy wear resistant refractory castable from RS.
