Relining of a Melting Chamber with Rounded Transitions
Sharp inside edges are the first damage — so there are none
Initial situation
In a furnace lining, sharp inside edges fail first, not the surface next to them: stress is highest at the edge, and both flame and flow attack there. When relining a melting chamber in August 2026, SBS Refractory Service therefore made the geometry itself the protection.
Scope of services
- Relining
- Monolithic lining
- Gunning mix
- Coves
- Burner opening
Project data
The task
Right angles between wall and floor concentrate stress along a single line
Stepped openings give flame and flow an edge to attack
Build-up clings to edges and has to be knocked off — which damages the lining every time
The SBS approach
Every transition from wall to floor was executed as a cove instead of a right angle. The radius distributes the stress across the surface.
Openings such as the burner opening were formed conically instead of with a step. This way neither the flame nor the flow finds an edge.
The chamber was monolithically cast and gunned — only in this way can this geometry be produced at all. In brickwork it could not.
