Cement kiln industry

Key area

Rotary kiln firing zone

Transition zone/cooling zone

Cooler cooler

Types of refractory bricks

Firing zone: Magnesia-chrome bricks/magnesia-iron spinel bricks

Transition zone/cooling zone: High alumina bricks/magnesia iron bricks

Kiln head cover/cooler: corundum brick/high-strength wear-resistant brick

Resistant to alkaline erosion (K₂O/Na₂O/SO₃ flue gas)

Thermal shock resistance

It also takes into account the performance of hanging kiln skins

Influence

Energy-saving kiln skin stability → Fuel consumption decreases by 2-5%

The lifespan of the fired bricks determines the kiln operation rate

Strong productivity and stable kiln skin → fewer furnace shutdowns

Environmentally friendly low-chromium environmental transformation (Cr6+ regulation)
