Steel fiber reinforced refractory castable,\u00a0is the refractory castable made of refractory aggregate, powder,\u00a0binder,\u00a0admixture\u00a0and steel fiber (heat resistant stainless steel fiber, generally 0.6%~2.5%). It has the characteristics of high strength, wear resistance and thermal shock resistance. Applicable to masonry at high temperatures with mechanical vibration, thermal shock, wear and other parts.<\/p>\n

Steel Fiber Reinforced Refractory Castable\u00a0Application<\/h2>\n

It is widely used in the steel, metallurgy, chemical and building materials industries in boilers and furnace outlets, tops, side walls, etc.; in CFB boilers, it is often used in furnace outlets and side walls, top, cyclone separators. , cyclone separator top, return feeder and other parts.<\/p>\n

Theoretical basis for steel fiber reinforcement<\/h2>\n

For general refractory materials, they are not wear-resistant during use, have poor seismic resistance, and are prone to cracking and crushing at high temperatures. The addition of steel fiber can greatly improve the strength and the cracking of the structure, thereby achieving the purpose of prolonging the service life of the furnace. The addition of steel fibers to the amorphous refractory material results in a significant improvement in refractory properties.<\/p>\n

The main features of steel fiber as a refractory reinforcement<\/h2>\n

(1) The strength of steel fiber is very high. According to the composite material rule, the toughness, crack resistance and peeling resistance of steel fiber after adding steel fiber increase, which is beneficial to the overall improvement of tensile strength and bending strength of refractory material.<\/p>\n

(2) In the steel fiber reinforced refractory material, since the steel fiber is present as a crack arresting expansion, it is intended to prepare a gradual expansion process of the microcrack generated in the refractory material under the action of thermal stress and mechanical stress.<\/p>\n

(3) Due to the action of the steel fiber in the refractory material, even in the case of cracking of the refractory material, it can be carried, thereby improving the fracture work of the refractory material and finally increasing the plasticity of the refractory material. The fracture work of the steel fiber refractory is more than several times greater than that of the steel fiber refractory. Therefore, the steel fiber increases the shock resistance and mechanical shock resistance of the refractory material.<\/p>\n

Compared with non-reinforced refractory castables, heat-resistant steel fiber reinforced high-aluminum castables have excellent toughness, high strength, good impact resistance and thermal shock resistance. They can be used in key areas to significantly improve the performance of refractory castables. Extend the service life of refractory products.<\/p>\n

The use of steel fiber reinforced high-aluminum castables can reduce the number of furnace inspections, save refractory materials, and reduce furnace costs and furnace fuel. At the same time, the operating rate of the kiln was increased, the production time was increased, the output was increased, and obvious economic benefits were obtained.<\/p>\n
