Steel fiber castable is used in the exit, top, side wall and other parts of boiler and furnace. It is widely used in steel, metallurgy, chemical and building materials industries. Refractory castable is also called unshaped refractory castable. Its use The method is basically the same as the use of concrete. After the selected formula and raw materials are mixed and processed evenly, the vibrating rod can be used for compaction and curing and heating treatment. However, due to the particularity of the use part of the unshaped castable, it is based on the site conditions. The construction quality of the castable also needs to be guaranteed. On the basis of using high-aluminum clinker as aggregate and powder for its important part, the characteristics of the appropriate steel fiber pouring reinforced castable are high strength, good toughness and good thermal shock stability, peeling resistance and resistance. It has the characteristics of strong grinding performance and is used in the parts where temperature step changes are more likely to cause damage to the furnace wall. Steel fiber castable has the characteristics of high strength, good toughness, good thermal shock stability, peeling resistance and strong wear resistance. Widely used in cement rotary kiln kiln mouth, cooler, coal injection pipe, decomposition furnace, preheater and other parts. Steel fiber castable is made of special grade bauxite clinker as aggregate, high-quality bauxite clinker and fine corundum powder as matrix, superfine powder and other composite materials as binders and additives, plus stainless steel heat-resistant fiber. become. In addition to the conventional high-temperature abrasion resistance, this product has a certain amount of heat-resistant stainless steel fiber added to its ingredients, which prevents the difference between the aggregate and the matrix in the material at high temperatures, and the furnace is started and stopped. The stress caused by the temperature gradient change generated at the time of the furnace caused the destruction of the furnace wall. At the same time, due to the addition of steel fibers, the overall strength of the furnace wall was greatly enhanced after the material was poured. In CFB boilers, it is often used in furnace outlets, side walls, tops, straight sections of cyclones, tops of cyclones, and return materials.
