Foundry Furnaces
Refractory construction and repair for foundry furnaces – melting furnaces and cupola furnaces for the ferrous and non-ferrous casting industry.
Refractory construction for Foundry Furnaces
Foundries are among the most demanding operating environments for refractory materials: extreme temperatures, aggressive slags and permanent contact with liquid metal push the furnace lining to its limits. SBS Refractory Service is your specialist partner for all refractory work on foundry melting furnaces and cupola furnaces.
Whether an induction melting furnace for ferrous and non-ferrous metals or a classic cupola furnace for cast iron production — our teams have mastered the specific requirements of every furnace type. We select materials that are matched precisely to the metal being melted, the slag chemistry and the operating conditions.
Minimum shutdown times are decisive in foundries. That is why we plan our assignments in close coordination with your production schedule and ensure execution on time — throughout Germany.
Typical challenges
Extreme thermal loading from metal temperatures above 1,500 °C
Chemical attack on the lining by aggressive slags
Mechanical wear from charging and tapping operations
Short maintenance windows call for efficient work sequences
2 furnace types — Foundry Furnaces
The right refractory solution for every furnace type — from complete relining to preventive maintenance.

What lies behind the melt inside the crucible.
From the inside an induction crucible looks like a smooth bowl. In fact, after the first heat-up the rammed mass consists of three layers: sintered and dense on the inside, part-sintered in the middle, deliberately loose on the outside at the coil. That outer layer is not a defect — it allows the lining to be broken out at a change without damaging the coil, and it stops a crack coming from the inside. Turn the model and look at the cut face.
- Inside
- sintered layer, dense
- Middle
- transition layer, part-sintered
- Outside
- loose layer at the coil
- Around it
- Induction coil
Schematic model: it shows the ratios of the three layers, not the dimensions of a particular crucible.
