SP-MSM-300 Arc Melting System with Electromagnetic Stirring and Vacuum Casting
Its core component is a water-cooled stainless steel vacuum chamber capable of achieving practical vacuums down to 5×10-6 torr, with an ultimate vacuum reaching 7×10-7 torr. The chamber includes tinted observation windows and a hinged front door for operational convenience. A built-in wobble stick allows sample flipping without breaking vacuum, enhancing process efficiency.
Wichtigste Merkmale
- 630 A arc melting power supply with high-frequency arc ignition, enabling contactless sample melting.
- Water-cooled copper hearths with multiple cavities for simultaneous melting or vacuum casting, including electromagnetic stirring options.
- Interchangeable hearth designs to accommodate different sample sizes and casting requirements.
- Water-cooled ceriated tungsten electrodes (Ø12 mm) for stable arc generation.
- Optional vacuum system with a 700 L/s turbopump and rotary vane backing pump for enhanced vacuum performance.
- Optional recirculating water chiller with precise temperature control to maintain cooling efficiency.
- Capability to use high-purity inert gases or hydrogen-argon mixtures to prevent oxidation during melting.

Typische Anwendungsbereiche
Ideal for research and development of advanced steel alloys, the SP-MSM-300 supports uniform melting and casting under controlled atmospheres. It is suitable for producing homogeneous alloy samples, vacuum casting rods, and exploring electromagnetic stirring effects on melt dynamics.
Hinweise zur Konfiguration und zum Betrieb
The system includes interchangeable copper hearths for either electromagnetic stirring or vacuum casting; users must specify the preferred hearth type when ordering. The wobble stick enables sample manipulation without venting the chamber, preserving vacuum integrity. High-purity inert gases or hydrogen-argon mixtures are recommended to minimize oxidation during melting. Optional vacuum and cooling systems enhance performance but are not included as standard. Proper installation of a two-stage pressure regulator on gas cylinders is required for safe operation.
