Εργοστάσιο τούβλων λιωμένου κορουνδίου

Fused corundum brick is mainly composed of α-Al₂Ο₃, which has high-temperature resistance, strong alkali resistance, συμπαγής δομή, excellent chemical stability, strong wear resistance, and is far more resistant to various slags than other aluminum silicates. It is an ideal material for metallurgical electrolytic cells and sliding rail bricks for heating furnaces.

The production process of fused corundum brick

Fused corundum bricks are melted alumina in arc aluminum and then cast into a specific model, so the customization of fused corundum bricks needs to change different molds; through diamond abrasive processing, the required fused corundum bricks can be obtained.
