Refractory plastic is made of refractory aggregate and powder, raw clay and chemical composite binder and admixture, which has good plasticity after preparation and mixing, extrusion into brick shape, packaging and storage for a certain time, and can be constructed by tamping method. According to the variety of refractory aggregate can be divided into clay, high alumina, mullite, corundum, chromium, silicon carbide and zirconium containing refractory plastics.

The wear-resistant plastics are generally mullite, corundum, silicon carbide and so on. The plastic has good shock resistance and easy construction. It is suitable for various heating furnaces, soaking furnaces, annealing furnaces, hot blast furnaces, etc. It can also be used for the furnace cover of small electric arc furnaces and the burner of high temperature furnaces.



Refractory castable is composed of refractory aggregate, powder and binder mixture, add water or other liquid, suitable for casting, vibration method construction, wear-resistant series castable generally high aluminum, mullite, corundum, silicon carbide and other series wear-resistant castable. The wear-resistant castable has the characteristics of anti-penetration, anti-erosion, anti-impact, anti-wear, good mechanical properties, etc., and is widely used in the front and back arch, top, and rear wall of power station boilers and other thermal kiln furnaces.

Two kinds of wear-resistant series of refractory materials, the name is similar, the location is actually similar, the difference is their function. However, due to its good plasticity, plastics are generally used for kiln repair and filling. Wear-resistant castables are generally used as lining materials in areas with serious wear. Most of the wear-resistant castable is mixed with water into mud that can be constructed by pouring method. After pouring molding, it can be demoulded after a period of maintenance, and then it can be put into baking use after natural maintenance for an appropriate time. Refractory plastics need to be combined with a binder, using the tamping method of construction. Commonly used binder categories are: clay binding plastic, phosphate binding plastic, aluminum sulfate binding plastic and so on.
