Steel fiber reinforced Low Cement Castable Refractory / High alumina
Castable Refractory
Fiber Reinforced Castable Refractory refer to the refractory castables that can increase the strength after adding fibers to the refractory castables. Fiber Reinforced Castable Refractory can be divided into steel fiber reinforced refractory castables and alumina fiber reinforced refractory castables.
Fiber Reinforced Castable Refractory is characterized by high strength, good toughness, strong thermal shock resistance and good spalling resistance, and it 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.
Steel Fiber Reinforced 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.
The heat-resisting steel fibers used for steel fiber refractory castables should be selected according to the conditions of use of thermal equipment and the appropriate amount should be determined. The preparation process is as follows: firstly weigh the refractory aggregates, powders, binders and admixtures, and dry-mix for one minute; secondly add water and wet mixing, and evenly spread the steel fibers into the material, and do not clump; finally mix for one minute Can be discharged. The total mixing time must not be less than 5 minutes. When the vibrating rod is used for molding, the vibration direction should be staggered to make the distribution of the steel fiber reasonable, which can improve the performance.
Steel Fiber Reinforced Castable Refractory is applicable to:
Masonry high temperature mechanical vibration, thermal shock, wear and other parts.
In the steel, metallurgy, chemical and building materials industries are widely used;
In the CFB boiler, often used in furnace outlet and side wall, top, cyclone straight section, cyclone top, returner and other parts.
