Upper Sidewalls         
Magnesia-chrome direct-bonded key brick to withstand the temperature and physical abrasion from the scrap steel charge.

Slag Line                   
Magnesia-carbon brick made with high purity fused magnesia, graphite flakes, with total carbon up to 15%.  Anti-oxidant metals can be included.  Standard 13.1/2”, 15”, 18”, 21” and 24” keys are available. Other non-standard shapes can be provided. 

High magnesia burned brick, with and without tar-impregnation, to provide a strong safety lining in the event the monolithic hearth refractory is eroded. 

Hearth Monolithic     
72% magnesia with excellent sintering to withstand the impact of scrap charge, molten steel and molten slag.  Versions for cold and hot application are available. 


Wear Pads                 
Alumina-magnesia-carbon bonded brick to take the brunt of the impact of the molten steel charge stream. This can be for the side wall or floor.
