Pre-Fused Slags FOR REMELTING APPLICATIONS
Electroslag Remelting Flux
Proven slag systems for most demanding remelting applications – technically designed for process stability, cleanliness and reproducibility.

Operational Process Design
Our portfolio comprises more than 30 different ESR flux types, developed for a wide range of steel and alloy grades. Many of these fluxes are based on defined systems and adapted to specific customer requirements within validated technical frameworks.
Continuous development and metallurgical expertise are essential to meet increasing cleanliness requirements in modern ESR applications. Our flux systems are therefore continuously reviewed and further developed with a clear focus on maintaining stable process windows and reproducible remelting behavior under industrial conditions.
To achieve optimal results, we support our customers with technical know-how and application-specific recommendations for demanding remelting processes and special alloy grades.
Quality assurance and responsibility
Quality is not only created at the production site – it is verified, released and supported throughout all of our processes.
Our approach includes:
- Defined and documented slag systems
- Batch-based production and traceability
- Local technical support and clearly defined escalation paths
This ensures reliable integration of ESR fluxes into demanding remelting processes.
Individual Service
Slag customization is an important part of the ESR remelting process.
Hence process requirements vary depending on steel grades, furnace concepts and process parameters, we offer customization options based on defined and validated slag systems. Adjustments are performed within controlled parameters to ensure performance and traceability.
Our technical team supports customers during qualification, implementation and ongoing operation of ESR fluxes. We can make application-oriented recommendations in order to provide and support stable remelting conditions for consistent metallurgical results.
