Magnesia-Herringbone Refractory Bricks from Mexico

Magnesia-Herringbone Refractory Bricks are herringbone-patterned magnesia bricks with a MgO content exceeding 50%, designed for improved gas flow in tunnel kilns and reheating furnaces. The angled design prevents brick movement under thermal cycling, and the bricks are fired after shaping to achieve the required properties. They are classified under 6902.10.00 as refractory ceramic constructional goods with a high magnesia content.
