Raw materials for preparing magnesia carbon bricks

The raw material for preparing magnesia-carbon bricks is fused magnesia with 98% MgO content. Magnesium-carbon bricks have the characteristics of low porosity, resistance to slag erosion, thermal shock resistance and high high temperature strength. They are mainly used for Alkaline oxygen furnace, magnesia carbon brick manufacturer, ladle furnace slag line and electric arc furnace hot spot. Magnesia carbon brick is a high-quality refractory material. Their main components are magnesium oxide and carbon, where the magnesium oxide content is 60-90%, and the carbon content is 10-40%. This material is made of high-purity magnesium oxide particles, carbon materials, tar, pitch or resin after high temperature baking. These magnesia refractory bricks have slag corrosion resistance, thermal shock resistance, thermal conductivity and other characteristics.

Magnesia carbon brick is an unburned carbon composite refractory material. It is made of high melting point (2800℃) alkaline oxide magnesium oxide and high melting point carbon material. This material is difficult to be corroded by slag and added Various non-oxide additives and carbon binders.

As a composite refractory material, magnesia-carbon brick effectively utilizes the strong slag corrosion effect of magnesium, effectively improves the thermal conductivity and low expansion of carbon, and makes up for the biggest shortcoming of poor spalling resistance of magnesium. Magnesia-carbon bricks are mainly used for linings of converters, electric arc furnaces, DC electric arc furnaces, and ladle slag lines.
