The banding technology of granular refractory fiber castable
The banding technology of granular refractory fiber castable. Granular refractory fiber castable high strength, excellent thermal shock resistance, good insulation properties. As the columnar aggregate formed by the small stress, and will not damage the coherence of the product, and its own cross-network structure, can resist external force, so that the material has a strong mechanical properties.
In the conventional refractory fiber castable, as the aggregate of refractory fiber cotton without oil into one, in the mixing process, the mud continued to penetrate into the pores of the fiber, the destruction of the fiber insulation effect, and granular refractory fiber casting The material still retains the fiber porosity, and the dispersion is more uniform, the bulk density is also larger than the ordinary refractory fiber products, which determine the granular refractory fiber casting material with better insulation effect.
Comparison of Heat Loss Between Water - tube Casting and Conventional Refractory Castable. Granular refractory fiber castable with high strength, high temperature, low thermal conductivity of the thermal insulation properties, and its thermal insulation effect can be calculated through the heat loss wall. Take the size of φ152mm X 25mm water pipe as an example.
The temperature of the cooling water in the water pipe is maintained at t3 = 36 ℃, the temperature of the furnace is t1 = 1320 ℃, the thickness of the dressing material is 80mm. Taking the conventional refractory castable - low cement castable as an example, Its average thermal conductivity λ2 = 1.4W / (m · K), then through the unit length of the heat pipe heat
If the use of granular refractory fiber castable dressing, 550 ℃ when its average thermal conductivity of λ = 0.43W / (m • K) then the unit length of the water pipe heat dissipation:
Granular refractory fiber castable pipe dressing ratio using low cement castable water pipe bandage heat loss:
As the working environment of the water pipe is in the high temperature and temperature gradient, and to withstand a certain pressure and mechanical vibration. This requires the dressing material should not only have a good thermal insulation properties, but also have a certain mechanical properties and high thermal shock resistance. Granular refractory fiber casting with heavy refractory castable and lightweight refractory castable advantages, is an ideal dressing material.
