High Refractoriness Degree Magnesia Fired Brick For Metallurgical Furnace
Magnesia Fired Brick
High-quality Magnesia Fired Brick is a product made of high-grade molding and high-temperature firing using first-grade magnesia and high-purity magnesia as raw materials. Fused Magnesium Brick has excellent heat resistant and high resistance to alkali slag erosion.
No matter standard size or special-shaped magnesite brick, CH Refractories provides customized magnesite refractories according to customers. We specialize in magnesium brick for years and we always treat each customers with sincere service.
The regular magnesia bricks are made from dense dead burned magnesia that makes the bricks in good refractoriness, corrosion-resistance, and widely used in checker chamber of glass tank, lime kiln, non-ferrous metallurgical furnaces, open heart furnace, iron mixer and EAF of steel-making, and also ferro-alloy furnace, etc. The bricks with MgO 95% or more in content take the secondary-burning dead burned magnesia or electrofused magnesia as the raw material and bured under the condition of ultra high temperature. They have the features of highly directly bonded and corrosion-resistance and widely used in various kinds of high temperature kilns and furnaces
