15KW 1700℃ Max. Vacuum Induction Heater with Material Feeding Ante-chamber & Melt Stirring Mechanism

The 15KW 1700℃ Max. Vacuum Induction Heater with Material Feeding Ante-chamber & Melt Stirring Mechanism is a sophisticated system designed for the preparation of metal alloys with varying melting points. This comprehensive system features an 18KW induction heater, temperature controller & TC, a 150mm O.D quartz tube with ante-chamber, water-cool flanges & valves, pressure gauges, graphite crucible & refractory assembly, a 58L/m recirculating water chiller, a 156L/min vacuum pump, and a mobile cart.

Operating at a working voltage of 220V AC, 50/60Hz, Three Phases, the 15KW induction heater offers a range of technical parameters, including a working current from 5 to 52 Amps, a maximum input power of 15 KW, and an adjustable output frequency between 30 and 80 kHz, featuring an 80% duty cycle. A distinctive feature is the Φ50×120H mm quartz ante-chamber, allowing sequential addition of source materials into the crucible without compromising the vacuum or atmosphere of the main chamber, making it ideal for alloy preparation. The system includes an SS retractable stirring rod for melt stirring, extendable inside the graphite crucible, with an alumina-tipped option available upon request.

The high-purity graphite crucible has a maximum loading capacity of 200ml, and the refractory assembly, crafted from alumina, includes bottom crucible support, crucible holder, and cover. Safety features include a PVC protective shield, a pressure relief valve, and temperature control through a precision digital controller with automatic PID tuning. The continuous working temperature ranges from 800℃ to 1700℃, with pressure sensing ensured by an anti-corrosive capacitance diaphragm gauge.

The system's sealing incorporates a 150mm(OD) x 142mm(ID) x 400mm(L) Quartz furnace tube with a 6'' stainless steel water-cooled top flange and a 6'' stainless steel bottom flange. The included 156 L/min Double Stage Rotary Vane Vacuum Pump supports vacuum operations, and the system is equipped with KF25 right-angle valves & clamps and a 1000mm long SS bellows for connection. Product dimensions include the induction heater, water chiller, and a heavy-duty mobile cart. The system is backed by a one-year limited warranty with lifetime support, excluding consumable parts, and has a net weight of 300 lbs.
