Magnesia carbon brick

Product category|Magnesia Brick

MgO: ≥70%
Bulk Density: ≥2.8g/cm³
Online Time: 7*24 hours

Product Description

Refractory products made of magnesia and graphite as the main raw materials (carbon content is generally 10%~25%), have low apparent porosity, excellent resistance to slag erosion, resistance to slag penetration, thermal shock stability and thermal conductivity.

Product Features

Lower apparent porosity

Excellent resistance to slag erosion

superior resistance to slag penetration

Good thermal shock stability

Strong thermal conductivity

Product Application

Magnesia carbon bricks are widely used and can be used in key parts of thermal equipment such as steelmaking converters, electric arc furnaces, steel drums, and refining furnaces outside the furnace. Alumina-magnesia carbon bricks made of high-quality bauxite clinker, fused corundum and fused magnesia have small thermal conductivity, good thermal insulation and appropriate residual expansion. They are used for ladles, lower ladle walls, ladle bottoms and free areas. good material for department
