A Single basic oxygen furnace (BOF) demands different types of refractories designed according to their distinct physical and thermo-chemical properties.
One key objective for Full Line Service clients is to develop refractories that last longer and are consumed homogeneously within each equipment for each customer in each plant.
Refractory consumption on the converter walls was diagnosed as heterogeneous, potentially leading to premature disposal of other refractories within the converter. Replacing an entire wall would lead to higher downtime of the equipment and more refractory use.
