Mullite Bricks are made of synthetic fused mullite or sintered mullite, pressed by selected shaping processes and fired in high temperature furnaces. Mullite bricks offer high density, low porosity, good hot strength and good sag resistance. Mullite bricks are preferred for high temperature, high load applications, such as at the hot end of regenerative chambers of glass melters, the superstructure of the furnace, and the arch of glass fiber melters, due to their excellent thermal properties, excellent strength at high temperature, great resistance to thermal shock, etc.
Mullite Brick is made from high quality alumina,mullite and fused mullite,it has good insulation effect,good thermal shock resistance,high strength under high temperature and low impurity.
Based on the clinker brick for coke oven, the company developed acid-resistant brick, the renewal product, through the improvement of the techniques and formula. The product is widely used for chimney lining, acid-resistant pool, and acid-resistant and abrasion resistance ground of some fields, such as electric power industry and petrifaction industry. The company is famous for great varieties of designs and can also process the product according to client's need.
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)
Typical Application:
Light weight brick can be used as heat surface refractory lining or other refractory material backing heat insulating layer, used in melting furnace, firing kiln, flue, refining device, heating device, regeneration unit, gas furnace and pipeline, soaking furnace, annealing furnace, reaction chamber and other industrial thermal equipment.
