4. Delivery condition: normalised
Note regarding the material selection: due to obvious advantages in terms of service life and maintenance
cost-efficiency, cast steel has been becoming more significant in the slag pot construction over the last
years versus both materials, spheroidal cast-iron and lamellar graphite cast-iron. In contrast to other
materials, cast steel offers excellent repair possibilities as it is well-suited to welding.
5. Quality assurance
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000.
The standard documentation ensures the full traceability of every process step:
• Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition,
mechanical properties and non-destructive examination;
• Dimensional check supported with a “as-built“ sketch;
• Record of the quality heat treatment;
