MAGNESIA BRICKS

MAGNESIA BRICKS

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.
