Steel fibers castable in boiler and furnace outlet, the top and side walls and other parts are used, is widely used in iron and steel, metallurgy, chemical industry and building materials industry, also known as refractory castable unshaped refractory castable, its use to actually use concrete and a good choice, selected formulation and the raw material after mixing evenly, with dense vibration rod and heat treatment after curing it can be, but because of the particularity of unshaped castable use parts, so according to different site conditions, the construction quality of castables also need to ensure.
Characteristics and construction method of steel fiber refractory castable
In the important part of high alumina clinker as aggregate and powder based on adding steel fiber pouring appropriate reinforcement characteristics of castable is high strength and good toughness and good stability, anti spalling and wear resistance, thermal shock, temperature for the step change leads to the damaged parts of the furnace wall.
The steel fiber castable has the characteristics of high strength, good toughness, good thermal shock stability, strong resistance to spalling and wear resistance. Widely used in the cement rotary kiln mouth, cooling machine, coal injection pipe, decomposing furnace, preheater and other parts.
Steel fiber pouring material is made of high grade bauxite as aggregate, by the high quality bauxite and corundum powder as matrix, with many kinds of superfine powder composite materials such as binder and additive, heat-resistant fiber prepared with stainless steel. This product has the high temperature wear resistance of conventional, by adding a certain amount of heat resistant stainless steel fiber in the mixture, prevents generation of aggregate and matrix material in the condition of high rise, the temperature gradient and the resulting changes in the start and stop of the furnace when the stress caused damage to the furnace wall. At the same time, due to the addition of steel fiber, the material after pouring furnace wall greatly enhance the overall strength. In CFB boiler, commonly used in the furnace outlet and the side walls, the top of the cyclone separator, straight section, cyclone separator, top return feeder parts.
Steel fiber refractory castable products: steel fiber refractory castable with high alumina clinker or corundum as aggregate and powder, binders and the amount of heat resistant, stainless steel fiber and additives compounded hydraulicsetting castahle.
Steel fiber refractory castable has the characteristics of high strength, high temperature resistance, impact resistance, thermal shock resistance, good wear resistance and so on.
The material products of steel fiber refractory ordinary stainless steel fiber refractory castable and nickel plated stainless steel fiber reinforced castable two, including nickel plated stainless steel steel fiber refractory castable technology has more excellent high temperature resistant, anti twist performance.
Steel fiber refractory castable is mainly used in metallurgy, building materials and circulating fluidized bed boiler high temperature vulnerable parts.
