insulating fireclay bricks

We are a company specializing in manufacture of mullite insulating bricks in china. Our products are widely applied in middle and high temperature furances in the field of metallurgy, Aluminum, Petrochemical, Ceramics, Power and Glass industry,etc.The production is directly manufacture according to ASTM, JIS and DIN standard, that was certified by ISO9001:2008 quality management system. The production capacity is 5,000,000 pieces of standard bricks per year.

Mullite insulating bricks characteristics and advantages:
1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction.
5. Max service temp: Up to 1730C (3160F)
