Magnesia Brick is alkaline refractory product that made of high grade megnesia
molding by high temperature, the main crystalline phase is calcite,
it is with properties of high refractoriness, good anti-alkaline
slag performance, high refractoriness under load.
Magnesia Bricks Anti Alkaline Slag Resistance Refractory Fire Bricks re mainly used in steel-making alkaline open hearth furnace,
electric furnace bottom and furnace wall, converter permanent
layer, metal mixer working layer, non-ferrous metal smelting
furnace, high temperature tunnel kiln, cement rotary kiln lining,
glass furnace regenerative chamber checker brick etc.
