Arcast Melt Spinners and Strip Casters

A complete system

Arcast's new Melt Spinner casts a thin ribbon of rapidly quenched amorphous material in 100g batches, and is suitable for Al, Fe, Ni, and Cu alloys.

It uses induction melting in an inert atmosphere and a water-cooled, variable speed copper wheel to quench the metal and generate the ribbon.

• Complete system consisting of vacuum chamber, control cabinet, high vacuum dual vane rotary pump (or turbo pump option) for 9 x 10^-3, mbar vacuum.
• Produces rapidly quenched ribbons 1 - 20 mm wide.
• 3-way crucible positioning system.
• View ports for the optical pyrometer and for viewing the process.
• Types K, B or C thermocouple feed-through and temperature display.
• Cooling jets for above and below the cast ribbon. These may be used with helium for increased cooling melt ejection by way of gas top pressure over the melt.

208 - 400 VAC, 50/60 Hz, 35-75 kVA

Water

40 lpm below 30^⚬C

Gas

Argon or other inert gas
