These are the rejected refractories which are being used by the Refractory Plants and different metallurgical purposes.

Magnesite Bricks Mg0The Magnesite brick is one of the most widely used basic refractory bricks.Their main advantage is very high slag resistance to lime and iron rich slags. It is very important for steelmaking processes.Different grade magnesites used as raw materials produce Magnesia bricks of various qualities ( 85 % -95 %) . Synthetic magnesite and dead burnt magnesite, low in iron, boron and silica are used as raw materials for magnesite brick productionMagnesite refractory products have the properties of bearing high temperature, high refractoriness under load and good resistance to alkali. Magnesite refractory bricks are widely used in the basic zone of metallurgical furnaces, non-ferrous furnaces and regenerator of glass furnaces.

• Good resistance to basic slags
• Spalling resistance
• Strong abrasion and corrosion resistance
• High cold crushing strength
• Very strong and extremely durable

Magnesia Chrome BricksMagnesia chromes bricks are mostly commonly used in cement kilns and non-ferrous furnaces. Magnesite chrome brick comprise of magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient, periclase and spinel as main mineral components of refractory products.Magnesite Chrome Refractory Bricks are produced from sintered magnesia and chrome ore by sintering at high temperature. Magnesite Chrome Refractory Bricks have high bulk density and advantages of stronger thermal resistance.Magnesite Chrome Refractory Bricks are widely used for;

• Cement rotary kilns
• Glass kiln regenerators
• Permanent lining of steel furnaces
• Permanent lining of refining ladles
