Wear Resistant Refractory Castable

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 cfb boiler. It can be used as the high temperature wear resistance, and erosion resistance lining, such as the steel tank lining. Email to RS for quick Quote!

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 castables are 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 Applications

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 castables should be used in these in these parts.
