Magnesia Bricks
Magnesia Bricks for Safety & Permanent Linings
STA Commerce coordinates international enquiries for the documented MEHR.MAG.95 high-MgO magnesia refractory brick used in safety and permanent linings for basic open-hearth and electric furnaces, oxygen converters, hot-metal mixers and non-ferrous smelting furnaces. Grade, dimensions and application requirements are coordinated with relevant refractory suppliers or manufacturers.
Basic Refractory Protection Behind the Working Lining
Safety and permanent linings form a secondary refractory barrier behind the hot-face working lining. They protect the furnace shell, support the lining structure and provide additional protection if the working lining becomes worn or locally damaged.
High-MgO bricks are suitable for basic metallurgical environments because they are compatible with alkaline slags and basic refractory systems.
Typical Uses of Magnesia Safety Lining Bricks
The referenced product is intended for several basic metallurgical furnaces and permanent lining systems.
Basic Open-Hearth Furnaces
Safety and structural lining in basic furnace zones.
Electric Furnace Walls
Permanent lining behind the working lining of electric furnace walls.
