High alumina refractory bubble bricks adopt alumina bubble balls as the main raw materials, high-performance ultrafine powder as the annexing agent, and organic substance as the binding agent through molding and drying, and then are fired in the high-temperature shuttle kiln.
High alumina refractory bubble bricks contain more than 90% Al2O3 and are a lightweight refractory product mainly composed of corundum. Which belongs to a kind of refractory material with features of super high temperature, saving energy, and thermal insulation. Al2O3 and the appropriate amount of clay and bonding agent are used as raw materials, and gas-blowing agents are used in the preparation stage. The product has good high-temperature structural properties and can be used in industrial kilns at 1600~1800℃.
We can produce high alumina refractory bubble bricks with professional and personalized products and engineering services according to the actual working condition and requirements of each customer, to meet customers’ increasing demand for energy-saving and product quality improvement, our belief is: that quality and credibility is fundamental, technology and service is the life.
1. High purity
2. High mechanical strength
3. Low thermal conductivity
4. Low bulk density (lighter than the same kind of material, thin kiln wall, low cost)
5. Mainly apply to the insulation layer of the coal-water slurry gasifier
6. Excellent thermal insulation
7. Good chemical stability (acid-base erosion resistance)
8. High compressive strength
1. High service temperature.
2. High purity.
3. Low thermal conductivity.
4. Low bulk density.
5. High mechanical strength.
High alumina refractory bubble bricks are mainly used in industries such as metallurgical, non-ferrous, refractory, ceramics, petrochemical, etc. It can be used as the hot face refractory lining of a pyrolyzer, hot blast furnace, reheating furnace, tunnel kiln, pushed slab kiln, crucible furnace, electric furnace, etc.
High alumina refractory bubble bricks are used as the main refractory lining for hot surfaces or as an insulation material behind other refractories in furnaces, flues, kilns, and similar high-temperature industrial equipment.
High alumina refractory bubble bricks are carefully handled during storage and transportation to preserve the quality of our product in its original condition.
