15KW 1700C Max. Induction Heater (6" Tube) with Dose Feeding Ante-chamber & Melt Stirring Mechanism - SP-60KTC

Please email for lead time
Item Number: SP60KTC
SP-60KTC is a 1700ºC temperature-controlled induction heating/melting system with source feeding ante-chamber and melt stirring mechanism. The quartz antechamber with tipping-over tray design is used to transfer various source materials into the crucible without affecting the clean environment inside the main chamber. It is an ideal tool for preparing metal alloys with compositions of different melting points.
The system includes an 18KW induction heater, temperature controller & TC, 150mm O.D quartz tube with ante-chamber, water cool flanges & valves, pressure gauges, graphite crucible & refractory assembly, 58L/m recirculating w
ater chiller, 156L/min vacuum pump, and a mobile cart

Induction Heater
  • Working Voltage: 220V AC, 50/ 60Hz, Three Phase

Material Feeding & Melt Stirring      
  • A Φ50×120H mm quartz ante-chamber was installed on the top of the main chamber for sequentially adding source materials into the crucible without breaking the vacuum or atmosphere of the main chamber. Such a unique feature provides the opportunity for preparing metal alloys with compositions of different melting points
  • The SS retractable stirring rod can reach and stir the melt inside the graphite crucible (stirring rod with alumina tip is available upon request, the additional cost will apply.)
  • A gate valve is employed for isolating/open the ante-chamber from/to the main chamber when material adding or melt stirring is needed
  • Material feeding port and tipping over tray diameter: Φ30
Graphite Crucible, Refractory liners & Protective Shield
  • High Purity Graphite Crucible: 73 O.D × 63 I.D × 140 Hmm is included for induction heating and metal smelting. Max. Loading Capacity: 200ml

  • Attention: Protective inert gas must be continuously filled throughout the experiment in order to protect the graphite crucible and C thermocouple. The gas flow rate should be limited to < 200 SCCM ( or 200ml/min)
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages
