Custom Phosphate Bonded High Alumina Bricks
JHYRef provides custom phosphate bonded high alumina bricks based on alumina content, brick grade, size, shape, quantity and working conditions. Custom production is suitable for kiln projects with special lining structures or non-standard brick dimensions.
If you have drawings or existing brick samples, we can help match the required size and recommend suitable material grades.
Applications
Phosphate bonded high alumina bricks are widely used in high-temperature industrial applications, including cement rotary kilns (transition zone, preheat zone, and cooler lining), lime kilns, and rotary kilns for metallurgical solid waste and magnesium production. They are also suitable for steel and non-ferrous metal smelting, as well as ceramics, glass, petroleum, chemical, and power industries.
