The Difference Between Wear-Resistant Plastic And Refractory Castable

Refractory plastic and refractory castable are two different refractory materials. There are great differences between them, not only in their composition but also in their construction methods. Next, I will show you the difference between wear-resistant plastic and refractory castable.

1. Composition

Wear-resistant refractory plastic is a refractory material that is made of refractory aggregate and powder, raw clay, chemical compound, and admixture, and is mixed and extruded into a brick shape, and still has good plasticity after being packaged and stored for a certain period.

Refractory castable is composed of refractory aggregate, powder, binder, and other materials. It is made into refractory material through mixing, molding, hardening, and other processes, and the whole is in powder form.

2. Construction method

Wear-resistant plastics are usually constructed by ramming, vibration, and other methods. They are suitable for construction all year round. No maintenance is required after construction. The temperature can be raised immediately. The furnace heating rate is 50℃/h. Generally, the furnace temperature required for production operation can be reached in 24 hours.

Refractory castables are suitable for construction by pouring and vibration methods and are mostly used to construct industrial furnace linings. After construction, it is necessary to wait for solidification, curing, and a long furnace drying process. It is not suitable for construction in winter, and antifreeze must be paid attention to.

The above is the main difference between wear-resistant plastics and refractory castables. Generally, when we choose, we should use them according to the actual use needs, to ensure that the castable has a good service life as a whole and ensure the stability of the kiln.
