Magnesia carbon brick is produced by high pressure molding process, using high purity, high density fused magnesia or large crystal magnesia and high purity graphite as raw materials.
As a kind of composite refractory material, magnesia carbon brick effectively utilizes the strong slag resistance of magnesia and the high thermal conductivity and low expansion of carbon to compensate for the poor spalling resistance of magnesia.
PRODUCT ADVANTAGES
High Strength and Good Slag Resistance
Steel ladle refractory materials are engineered with high structural strength and excellent slag resistance to ensure stable performance in demanding steelmaking environments.

The slag line is one of the most severely attacked areas in a steel ladle due to direct contact with aggressive slag.
Magnesia carbon bricks provide:
MgO-C bricks are widely used in working linings where they contact molten steel and experience continuous thermal and chemical stress.
Depending on steelmaking conditions, magnesia carbon bricks can also be selected for other high-wear areas requiring high-temperature durability.
Selecting the right MgO-C brick requires consideration of actual steel plant operating conditions.
| Selection Factor | Influence on Product Selection |
|---|---|
| Steel Grade | Different steel grades create different chemical corrosion conditions |
| Slag Composition | Slag basicity and oxidation level affect corrosion resistance requirements |
| Ladle Capacity | Larger ladles may require higher mechanical strength |
| Refining Process | LF, RH, VD and other processes create different thermal conditions |
| Service Life Target | Higher campaign life requires optimized refractory grades |
| Wear Location | Slag line, bottom and sidewall require different performance characteristics |
