Application Notes
The heater will shut down if over output occurs. Please reduce coil cycle number or sample size to keep heater operating under Max power
Melting time and temperature are related to materials, crucible, refractory insulation, etc. If you do not know whether the induction heater can melt your sample or not, please contact our engineer for consulting. Have your alloy's composition, melting point, and quantity to be melted prepared
The Induction Melting System is designed for use under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI and The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min
Warning: A pressure regulator must be installed on your input gas tank and have the output gas pressure set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition. Gas build up with pressure levels exceeding over 3 PSI may cause irreversible damage to the furnace chamber.
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.
This furnace can be modified as RTP ( rapid thermal processing ) and HPCVD system with gas delivery system. Please click link below to see how. If you have any special requirement, please let us know
