Light Weight Brick

  • Product Description:

    Lightweight firebrick has the characteristics of low density, high porosity, low thermal conductivity, good thermal insulation and certain compressive strength, it is widely used in heat treatment equipment.
  • Product Features:

    1, Lightweight firebrick has large porosity and loose structure, so it cannot be used in direct contact with slag and liquid metal; 2, Because of low mechanical strength, it can not be used for load-bearing structure; 3, Due to its poor wear resistance, it is not suitable for contact with the fireface and wear parts.
  • Application:

    Lightweight insulation bricks do not allow direct contact with flame, high temperature melts and are easily eroded in a chemical atmosphere. It is widely used in high temperature masonry of industrial kilns and thermal equipment.
