Copper crucibles and crystallizers for remelting equipment should be selected from furnace type, melt geometry, cooling system, interfaces and service history.
Application Definition
Identify the furnace and the function of the component before comparing material grades.
- State VAR, ESR, EB or other furnace type and relevant equipment model.
- Provide ingot or melt dimensions, cooling arrangement and installation interface.
- Include previous failure mode or service-life target when available.
Material and Construction
Pure copper, OFC and CuCrZr may be considered depending on conductivity, strength, joining and temperature requirements.
- Define whether the component is monolithic or welded.
- Review wall thickness, flange, sealing face and water connections.
- Coordinate blank route and machining allowance with the final geometry.
RFQ and Inspection
A complete RFQ reduces assumptions in quotation and production.
- Send drawing revision, material standard, quantity and delivery destination.
- List critical dimensions, NDT, pressure or leak testing and documentation.
- Add photographs or measured data when replacing an existing component.
