High alumina bricks for general uses are mainly made from super quality Bauxite, bonding chamotte and additives, being high pressure pressed and sintered in high temperature.
Application:
They were widely used in all parts of furnace lining of metallurgic, petroleum, construction materials, machinery and militaries, etc.
Features and advantages:
1. The dimensions are more exactly.
2. Low iron content and impurities
3. Good thermal stability;
4. High refractoriness,
5. anti alkaline /acid erosions,
6. Mechanical and chemical properties are very good.
7. Strong thermal shock resistance.
