Schmelzkorund-Ziegelfabrik

Fused corundum brick is mainly composed of α-Al₂Ö₃, which has high-temperature resistance, strong alkali resistance, kompakte Struktur, excellent chemical stability, starke Verschleißfestigkeit, 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.

Der Herstellungsprozess von Schmelzkorundsteinen

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.
