High temperature environments require minerals with exceptional refractory properties. Minerals and refractory products intended for usage in direct contact with hot liquid steel also need to exhibit high refractoriness and high resistance to chemical, thermal and mechanical stresses.
The choice of minerals within the steel producing industry determines both the service length of the protective refractory products used as well as the final quality of the resulting steel.
Sibelco’s refractory Olivine grades produce insulating linings in continuous steel casting and offer better insulating properties than comparable refractory raw materials such as dolomite.
Sibelco’s refractory magnesia grades are used in MgO-C, MgO-Dol, MgO-Spinel, MgO and AMC bricks as well as in special high-grade monolithics for the most severe areas in EAF, converters and ladles. They offer various advantages over other natural grades from macrocrystalline deposits as well as synthetic grades.
