Magnesite Bricks Mg0
The 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 production
Magnesite 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

Silicon Carbide refractories are produced from silicon carbide, a raw material synthesized in a resistance-type electric furnace at temperature exceeding 2500°C, through the reaction of silica with carbon. They have a thermal conductivity ten times that of fireclay refractories, good corrosion and thermal shock resistance, and can be formed into complex shapes. They can withstand slag attack and flame erosion. This makes CUMIFRAC unusual even among advanced refractories and has given it wide uses.

Outstanding Features

• Extremely high thermal conductivity
• Very high hot strength
• High erosion and abrasion resistance, thermal shock resistance
• Chemical inertness
