Dead Burnt Magnesite Gains Role in Hot Metal Desulfurization

Dead Burnt Magnesite Gains Role in Hot Metal Desulfurization

The global push for high-strength, low-sulfur steels in automotive and pipeline applications is tightening sulfur limits, often down to 0.005% or below. This trend is elevating the role of dead burnt magnesite supplier partners who can provide consistent, high-basicity magnesia for hot metal desulfurization stations. In Kanbara Reactor (KR) mechanical stirring and co-injection processes, magnesium oxide mgo for desulfurization serves not only as a flux to capture sulfur but also to modify slag fluidity and reduce iron losses. The crystal size of the magnesia significantly affects the slag-metal reaction kinetics; large periclase crystals in dead burned grades dissolve more slowly, maintaining slag volume and minimizing refractory wear.

Technically, the superiority of mgo oxide injection in powder form combined with lime and calcium carbide has been validated in numerous blast furnace shops. The lime-to-magnesia ratio must be carefully balanced to achieve both fast desulfurization and minimal temperature drop. Our dead burned magnesite 97, with MgO above 97% and CaO/SiO₂ ratio exceeding 2.5, provides the high liquidus temperature slag required for deep desulfurization. Being a vertically integrated magnesia for hot metal provider, CNMGO draws from its own kilns to ensure uniform physical and chemical properties, shipment after shipment.

Moreover, the demand for refractory magnesia that can double as both desulfurizing agent and conditioner for slag splashing in basic oxygen furnaces is growing. CNMGO Group Limited’s strict quality control system monitors every batch for hydration resistance and bulk density, ensuring our DBM withstands the rigorous environment of hot metal transport ladles and torpedo cars, helping steelmakers meet ultra-low sulfur targets.
