Product Application of High-strength alkali-resistant refractory bricks

Cement kiln alkali-resistant bricks are divided into four types: ordinary type, high-strength type, vault type and thermal insulation type. The preheater and decomposition furnace are located at the end of the entire hot air flow.

High-strength alkali-resistant bricks are mainly used in the preheater of cement kiln.

High-strength alkali-resistant bricks are mainly used in the calciner area of cement kilns.

High-strength alkali-resistant bricks are mainly used in the tertiary air duct of cement kilns.
