Refractory and wear-resistant plastics are refractory materials formulated from 70% to 80% granular and powder materials, plus 10% to 25% plastic clay and other binders and appropriate plasticizers.

But plastic can be made into sheet and block. Certain binders can also be added during construction. When used, the mixture is compacted or pounded, and after baking, it can form a dense inner lining and structure. Good plasticity before hardening; after hardening it has a certain strength. It has good sinterability, certain volume stability and other high temperature performance at high temperature. It is in the form of hard mud **, and maintains high plasticity for a long time. It contains more plastic clay components and more water than ramming materials. It is mainly used in various heating furnaces that are not in direct contact with the melt. The materials are mostly clay and high aluminum, but also silicon, magnesium, chromium, zircon and silicon carbide.

Mainly used in the lining of various heating furnaces, soaking furnaces, annealing furnaces, sintering furnaces and electric furnace roofs in the iron and steel industry.
