Melt Spinning Furnace
Product Details:
Vacuum Melt Spinning Unit is used for rapid solidification of a range of metallic alloys. The alloys are loaded as small chunks in a cruicible with a small nozzle or orifice at the bottom. The charge is melted by rapid induction heating in a vacuum or controlled atmosphere to avoid oxidation or contamination. The melt is ejected by applying inert gas pressure over the melt and is rapidly solidified as ribbon over a rotating copper wheel.
The unit consists of a vacuum chamber made of SS 304L material, High Vacuum Pumping System, Induction Melting Power Supply with matching coil, Melt Spinning Drive for copper wheel, crucible and crucible holder with pressure ejection device and XYZ movement of nozzle of the crucible, mirror with holder, gas feeding device and control console with standard system protection. The total system is mounted on a frame as the molten metal falls on the rotating wheels and metal tapes are formed. Spinning Charge : Ion, Nickle, Aluminium based or such alloys. Spinning Drive : Linear Speeds controllable between about 5 to 60 m/sec on a 40mm wide, 300mm dia copper wheel mounted on a shaft driver through a canned motor assembly of 2HP. Crucible Holder : With provision for continuously varying the angle of inclination and provides pressure ejection facility for molten metal to pass through the bottom nozzle on the copper wheel. Melting Device : 15 KW Induction power supply is used with a matching coil. The induction coil is made from water cooled 1/4" copper tube of dia 50mm. A mirror holder with plane mirror and a rotating mechanism is provided outside the chamber near the view port to observe sample temperature.
