Fireclay Brick

We are offering fireclay brick.
1. Fireclay refractory bricks characters:
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�, refractoriness under load is 1250-1450 �, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.
2. Applications:
widely used for lining of acid kiln, also used for blast furnace, hot blast furnace, glass kiln and high temperature kiln such as carbon baking kiln.
