VMC-1200 is a vacuum melting & casting furnace with stirring & secondary charge function that is capable of melting/casting various metal alloys up to 1000g (Fe as reference) at Max. 1200ºC. It is an excellent furnace for preparing various light metallic alloys, such as, Li, Al, Mg alloys, thermal electronics alloys, and phase transformation energy storage. This furnace is also excellent for preparing alloys of lithium anode, such as Li–3Al–1Yb electrode shown in the paper. SPECIFICATIONS: Power Requirements Power: 208 - 240 VAC, Single phase Max. 3500 power consumption A 10-foot power cable is included without a power plug Vacuum chamber The vacuum chamber is made of stainless steel Vacuum Chamber: Ø315 mm × 315 mm H (inner dimension) One Ø120 mm quartz observation window. Built-in a rocker arm to rotate the crucible and cast into a water-cooled copper or a refractory mold (Pic. 1) One KF25 and one KF40 vacuum port are built at the back of the chamber (Pic. 2) DN160 ISO-K port is built on the left of the chamber for connection of a turbopump Two KF16 and a KF25 port on the top of the chamber for a vacuum meter or other device The mechanical stirring function is built in for uniform alloying (Pic.3)) The secondary material feeder is included, which can feed 3 types of volatile dopants into the crucible during melting under vacuum (Pic 4 ) P1 P2 P3 P4 Crucible & Casting Mold Two graphite crucibles are included Graphite crucible 1: Ø47 OD × Ø35 ID × 88 H mm; working volume ~70 ml (up to 400g Fe alloy) Graphite crucible 2: Ø75 OD × Ø60 ID × 105 H mm; working volume ~250 ml (up to 1200g Fe alloy) Optional BN liners for graphite crucible are also available.
