1.Low porosity, high bulk density 2.High refractoriness under load 3.High mechanical strength 4.Good resistance to erosion

Features:

The low porosity fireclay bricks are made of super calcined flint clay and calcined bauxite, with high

pressure formed and high temperature sintered.

1.Low porosity,High bulk density.

2.Good cold crushing strength.

3.High refractoriness under load.

4.High mechanical strength.

5.Good resistance to erosion.

Applications:

Due to its low apparent porosity, strong resistance to erosion and high refractoriness under load, they

are widely used in various furnaces, especially suitable to the middle and low parts of regenerator in glass

furnaces.
