Laboratory Remelting Systems

Product catalog summary
Overview: ALD Vacuum Technologies provides advanced laboratory remelting systems designed for pilot production and research and development (R&D) purposes. These systems utilize both non-consumable and consumable electrode techniques to produce high-quality metal ingots and samples.
Technical Specifications:
  • Crucible Shapes: Available in disc, round, and round/square configurations across different models (LK 6, L 200, F 240, R 240).
  • Electrode Techniques: Non-consumable and consumable electrode techniques are employed, with varying capabilities across models.
  • Melting Power Supply: Ranges from 500-7500 A depending on the system.
  • Vacuum/Pressure: Systems operate under vacuum conditions with standard and diffusion pump options, achieving pressures as low as 10-4 mbar.
  • Cooling Water Consumption: Varies from 60 to 400 l/min based on the system.
Laboratory Systems:
  • Vacuum Arc Remelting (VAR): Utilizes an arc between a cathode and a water-cooled anode to improve ingot structure and uniformity. Suitable for materials like Ti, Ta, Zr, Fe-, Ni-, and Cu-alloys.
  • Electro Slag Remelting (ESR): Similar to VAR but involves melting under a superheated slag, reducing porosity and macro-segregation.
System Lines:
  • LK Line: Designed for non-consumable electrode technique, capable of operating under vacuum or inert gas atmospheres.
  • L200 Line: Supports both non-consumable and consumable electrodes, with a maximum ingot weight of 200 kg.
  • F240 Line: Uses consumable electrode technique, primarily for Fe- and Ni-based alloys, with a maximum mold diameter of 240 mm.
  • R240 Line: Supports multiple remelting processes, including VAR and ESR, under various pressure conditions.
Accessories: Systems can be equipped with various accessories to enhance flexibility and application range, such as automatic gas-inlet systems, material-feed mechanisms, and video monitoring systems.
Conclusion: ALD's laboratory remelting systems offer versatile and efficient solutions for producing high-quality metal samples and ingots, suitable for a wide range of industrial and research applications.

Electro Slag Remelting (ESR) Refining and Solidification Control Electro Slag Remelting Furnace Model F240 Electro Slag Remelting (ESR) The Electro Slag Remelting process in general is very similar to the VAR process. In ESR the ingot is formed under a superheated slag in which the electrode is immersed and melted off using an alternating current. Remelted ingots are free from porosity, macro-segregation and contain minimum content on non metallic inclusions.
