Steel fiber reinforced wear-resistant high alumina brick is a refractory material with excellent performance. It is mainly made of aggregates such as corundum and bauxite, and an appropriate amount of heat-resistant stainless steel fiber and binder, etc., which are mixed in precise proportions and fully mixed. The high-pressure molding process is used to make the required brick shape and size, and the medium-temperature heat treatment is carried out within a certain temperature range to promote the chemical reaction of various components in the brick to form a stable mineral phase structure, further improving the performance of the brick.
Its main performance characteristics are:
High Wear Resistance
The high hardness of corundum and alumina and the reinforcement of steel fiber make high alumina bricks have excellent wear resistance and can resist the erosion and wear of materials at high temperature.
Good Toughness and Mechanical Impact Resistance
The addition of steel fiber significantly improves the toughness of the brick, enabling it to withstand greater mechanical impact, less prone to cracking and damage, and has better stability during kiln startup, shutdown, and vibration during operation.
Good Thermal Shock Stability
Heat-resistant stainless steel fibers can effectively suppress the thermal stress generated by bricks when the temperature changes drastically, improve the thermal shock stability of bricks, enable them to withstand frequent rapid cooling and heating cycles, and extend their service life.
Good Volume Stability
In high temperature environments, steel fiber reinforced wear-resistant high alumina bricks have good volume stability, are not prone to expansion or contraction deformation, and can maintain the structural integrity of the kiln lining.
High Refractoriness
Because the main components are corundum and bauxite with high aluminum content, the brick has high refractoriness, generally reaching 1580℃-1770℃, and can work stably for a long time in high-temperature kilns.
Steel fiber reinforced wear-resistant high alumina bricks are widely used in cement industry, metallurgical industry, glass industry due to their excellent performance. They can also be used in high-temperature chemical reactors, cracking furnaces and other equipment in the chemical industry, as well as high-temperature kilns in the ceramics, building materials and other industries to resist the erosion of high temperature, acid, alkali and other chemical substances and the erosion of materials.
