Fire-caly bricks

The main chemical components:

Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750°C, refractoriness under load is 1250-1450 °C, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.

Highlight:

•Good thermal shock and thermal spalling resistance.

•High mechanical strength.

•Good resistance to abrasion and corrosion.

•Good volume stability at high temperature.

Applications:

It is widely used in metallurgy,construction (glass and cement), chemical industry, electric power and machine building.

Our refractory bricks are mainly including fireclay, magnesia, high alumina, silica and other refractory bricks, if you have any product need my help, feel free to contact me.
