Characteristics:
High alumina bricks has Al2O3 content ≥40%, its features are as below:
- High refractoriness under load.
- The RUL is higher than fireclay brick as the high content of Al2O3
- Excellent slag resistance
- All shapes can be customized according to request
Usage:
Alumina bricks are widely used in all high temperature industries, hot blast stove, hot furnace, coke ovens, pizza ovens, CDQ, rotary kilns, cement kilns, incinerators, secondary burning chamber, baking furnace etc.
1. Raw material to factory→checkout→burdening→stirring→mixing→taking out the raw material,
2)Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment.
2.Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
Brick Size or Shapes:
The shape can be customized according to the brick drawings.
