Magnesia Bricks for Safety & Permanent Linings
High-MgO refractory bricks for safety and permanent lining applications in basic open-hearth furnaces, electric furnaces, oxygen converters, hot-metal mixers and non-ferrous smelting furnaces.
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
