SP-15VSC is a 15KW induction heating/melting system with a Top-Vacuum-Suction mechanism. Such a unique feature can produce cast products ( 3 - 5 mm Dia. rod shape) by raising and introducing the molten metal into the top quartz feeding tube. The sucking force applied results in a fast movement of the melt and cause the rapid solidification of the melt inside the quartz feeding tube. It is an ideal tool for preparing small diameter alloy rod with reduced shrinkage cavity defects.

SPECIFICATIONS:

Induction Heater	Working Voltage: 220V AC, 50/60Hz, Single Phase Working Current: 5-52 Amp (60A breaker required) Max Input Power: 15 KW Output Frequency: 30 - 80 kHz Adjustable Duty Cycle: 80% Induction Coil: 70mm(OD) x 65mm(ID) x 80mm(H)  Auto Heating Time: 1-99 seconds Auto Dwell Time: 1-99 seconds Auto Cooling Time: 1-99 seconds Air Cooling: Rear Fan Protection: Automatic water pressure, over-temperature, and overpower protection
Vacuum-Suction Casting Method	A top casting utilizes the suction force to produce a 3- 5 mm rod shape metal alloy with ~150mm length Shrinkage cavity defects of the alloy can be significantly reduced by utilizing such a suction casting method The sucking force is generated by the rapid movement of the syringe piston (manually operated)  Observation window (12mm Dia.) on the top flange allows you to monitor the melt conditions  A 7 O.D x 4 I.D × 500 L mm quartz feeding tube is inserted from the feedthrough on the top flange. Warning: Never sucking cast metal alloy @ > 1200C to avoid damaging the quartz feeding tube

Warning Click here to learn more about the installation of a gas regulator.	Attention: Protective inert gas must be continuously filled throughout the suction casting process in order to protect the graphite crucible and the melt. 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.
