Refractory plastic material

Refractory plastic material is 70~80% granular and powder materials, plus 10~25% plasticity clay and other binder and the right amount of plasticizer made up, a hard paste, and in a long time to maintain a higher plasticity of amorphous refractory. Refractory plastic materials are mainly used in a variety of heating furnaces that are not in direct contact with the molten material, the material is mostly clay and high aluminum, but also siliceous, magnesian, chromium, zirconium and silicon carbide, etc. If classified by binder, clay binding, sodium silicate binding, phosphate binding plastic materials, etc.
