Alkali resistant brick
Introduction:
Alkali-resistant bricks for cement kiln can be divided into four types: ordinary type, high-strength type, vault type and insulation type. The alkali resistance mechanism is that it reacts with the alkali metal oxide at a high temperature to form a high-viscosity liquid phase, forming a glazed protective layer covering the surface of the refractory brick to block the pores to prevent the alkali metal melt, penetration and erosion.
Advantages:
Resistance to alkali erosion
Application:
1. Cement kiln preheater
2. Decomposition furnace
3. Tertiary air pipe
4. Back entrance
5. Kiln door cover
6. Grate cooler
