The working conditions of cement kilns are complex, and different parts have different requirements for the high temperature resistance, erosion resistance, wear resistance, and insulation performance of refractory materials. Therefore, it is necessary to choose and use them properly.
• Preheaters, calciner, and flue sections:
Mainly use alkali resistant bricks, alkali resistant castables, and lightweight insulation bricks, which have good alkali resistance and thermal insulation.
• High temperature areas such as transition zone and burning zone of rotary kiln:
Mostly use dense and high-strength refractory products such as magnesia alumina spinel bricks and high alumina bricks, which have high temperature resistance, chemical resistance, clinker erosion resistance, and strong stability.
• Heavily worn parts such as kiln mouth, cooler, and tertiary air duct:
Usually use high-strength wear-resistant castables and high-alumina wear-resistant bricks, with excellent resistance to erosion and thermal shock.
Huaxiang Refractories can provide a full range of refractory materials for cement kilns. Our products are stable, adaptable and long service life. They can meet the needs of different kiln types and various working conditions.
