Melt Spinner With Water Cold Copper Wheel and Temperature Control System upto 500g - VTC-500W

VTC-500W is an atmosphere-controlled melt spinning system for preparing amorphous metallic ribbons. In this technique, metal ingots are melted via the induction heating method and then propelled by pressurizing the crucible. A thin stream of molten is dropped onto a fast-spinning copper wheel, which can rapidly quench & solidify the molten, and consequently form the liquid metal alloy. 

The system features an SS air-tight chamber with a front observation window. A dual-stage oil pump is included for achieving a high vacuum (up to 10^-2 Torr). ISO 160 flange reserved for turbopump connection if necessary. The unit provides inlet and outlet valves for inert gas purging, which could avoid moisture and oxygen exposure while processing the melt spinning. The user can also control the speed of the wheel, the induction heating power, the temperature, and the pressure applied in melt spinning.

SPECIFICATIONS:

Features	A complete system consists of a stainless-steel vacuum chamber, a mechanical (or turbo) pump, a 15 kW induction heating system, a rack system, and a one-meter long discharging tubular collector. Copper flywheel with a maximum of 50 m/s (300mm Dia. Copper Wheel @ 2850 RPM) spinning speed. The distance between the crucible and copper wheel is adjustable (electrical adjustment via servo motor). Large LCD touchscreen control for temperature & induction power, copper wheel spinning speed & on/off, mechanical & turbopump on/off, solenoid valves for pump isolation and gas purging, melt-spinning on/off, and pressure monitoring. Maximum melting capacity around 500 g per batch (Note: material melting point < 1000°C). Thermocouple inserts to the bottom of the crucible which can measure the temperature of the crucible. (NOTE: directly contacting the thermocouple with the melt should be avoided.) Featured a position adjustable “scraper” can prevent ribbon spin-off to the inside of the chamber.
Power Requirements	Input Voltage: 220 VAC, three-phase, 60Hz. Input Power: 25 kW (A 70A breaker is required).
Vacuum Chamber & Vacuum Pump	Vacuum chamber: 500 × 550 × 700 mm (L × W × H). Hinged type door with a quartz observation window and illumination lighting which provide better sight viewing of the process condition inside of the chamber. Mechanical pump with KF40 port which can evacuate to approximately 5×10-2 Torr within 30 minutes. High vacuum level 10-6 Torr (with an optional turbopump, which is not included). ISO-160 vacuum flange is reserved for turbopump connection.
Induction Heater & Temp. Control	Dual station: 25 kW induction heater. Boron nitride crucible (optional). Maximum sample load: 150 – 500 g (material melting point < 1000°C, based on NdFeB. Crucible temperature, dwell time, and ejection time can be controlled automatically by the controller. The temperature controller is integrated with a thermocouple (24” long) inserting into the crucible wall. 30 programmable segments of temperature profile with ± 2 °C accuracy. Note: For materials with melting point > 1200C, a 30KW induction power supply is highly recommended at additional cost.  Please be advised that it is not every material that can be spun. In order to melt-spun successfully, material Melton must match suitable viscosity. It is the customer's responsibility to find the right composition, crucible size, and power supply.
Crucibles ( Optional )	We recommend using BN crucible for Ferro metallic material < 1200oC, which is not included Click the picture left to order the standard BN crucible. The customized BN crucible is also available upon request
Gas Pressure Regulator	PID pressure regulator is included to precisely control the pressurized gas applied to the crucible for pushing the molten out from the slit. Pneumatic solenoid valves are used to isolate the pumps from the chamber when not used, chamber purging, and pressure relief.
Optional	The Casting attachment is available upon request at extra cost, pic 1~3. Customized water-cooling copper mold is available upon request. Vacuum casting mold is available upon request Φ120X90mm at the additional cost, pic.4. Water chiller (KJ-6300) is available at additional cost, pic.5. The spinner may be connected with a dual glovebox for air-sensitive materials ( pic 6)                                                                                        Pic.1                         Pic.2                  Pic.3                Pic.4                Pic.5               Pic. 6
