90% Al2O3 Corundum Steel Fiber Strengthened Castable Refractory Dense Kiln refractory Materials
Dense Steel fiber strengthened Castable Refractory is made of special bauxite clinker as aggregate, high quality bauxite clinker and corundum fine powder as matrix, ultrafine powder and other composite materials as binder and additive, plus stainless steel heat-resistant fiber Made. At the same time, due to the addition of steel fibers, the overall strength of the furnace wall after pouring the material is greatly enhanced.
Corundum Steel fiber strengthened Castable Refractory with features of high strength, good toughness, strong thermal shock resistance, good spalling resistance etc.
Corundum Steel fiber strengthened Castable Refractory has been applied in the key parts of heat treatment furnaces, heating furnaces, soaking furnaces and other kiln furnaces and thermal equipment, and has obtained good technical and economic results.
Main uses:
1, In the steel, metallurgy, chemical and building materials industries are widely used;
2, Masonry high temperature mechanical vibration, thermal shock, wear and other parts.
3, In the CFB boiler, often used in furnace outlet and side wall, top, cyclone straight section, cyclone top, returner and other parts.
