Challenge:
The steelmaker was losing campaign length to magnesia-carbon lining erosion and spalling, and patching with inconsistent spare refractory was extending outages more than it saved.
Solution:
We supplied magnesia-carbon brick alongside high-alumina and firebrick spares as a matched set, with documented grade and consistent application support, delivered to keep a full repair kit on site.
Result:
Refractory erosion and spalling slowed, campaign length extended, and hot-spot patching reduced outage time and refractory cost per tonne.
A steelmaker running electric and basic-oxygen furnaces was losing campaign length to wear on the magnesia-carbon lining. Erosion and spalling in the working face forced earlier taps, and patching with spare refractory of inconsistent grade tended to extend outages more than it saved — the patches did not behave like the surrounding lining.
We supplied magnesia-carbon brick as the primary lining material, alongside matched high-alumina and firebrick spares, as a coordinated set rather than piecemeal items. Each refractory shipped with documented grade, and we supported consistent application practice and kept a full repair kit on site so that patching used material matched to the lining.
Refractory erosion and spalling slowed, campaign length extended, and hot-spot patching cut both outage time and refractory cost per tonne. For furnace campaigns, the consistency of the refractory — not just its nominal grade — is what determines whether the lining lasts.
