    High strength, explosion-proof and erosion resistant castable AS-20


    Product specification

    [product name] : high strength, explosion-proof and erosion resistant castable as-20

    [product model] : as-20

    Recommended site: kiln mouth

    Product information

    1. At high temperature, a layer of SiO2 film will be formed on the surface of castable to close the pores on the surface of refractories and prevent the erosion of refractories by alkali and sulfur oxides.

    2. High bending strength at high temperature is maintained at medium and high temperature, which can effectively resist the erosion and erosion of flying sand.

    3. Composite phase toughening technology is adopted to form micro-cracks inside the castable, which can effectively release thermal stress and enhance the thermal shock resistance of the castable in the process of lifting and cooling.

    4. During the construction process, bake at the same time to avoid pouring material bursting.
