Description of Magnesia Iron Spinel Bricks
On the basis of researching the same kind of products in the world, the MgO-Fe2O3 spinel brick was developed to be a chrome free environment protective product. It overcomes the shortage of producing low melting point calcium aluminate resulting in poor flexibility to the product. It is characterized by good thermal shock resistance, high resistance to infiltration, corrosion, stress intensity etc. It is mainly used in burning zone of large and medium dry-method cement rotary kiln.
