VBF-1200X-T is a compact vacuum arc melting furnace designed for melting small quantities of high-temperature refractory metals (up to 2000℃). It features a dual tungsten electrode with a maximum current input of 200A, with one electrode connected to a stainless steel crucible and the other inserted into a graphite crucible. The graphite crucible is heated by a low-voltage DC power supply, and the quartz tube is heated by a resistance furnace to ensure the temperature uniformity of the crucible. The furnace flange is equipped with a feeding device for adding dopping materials during melting. This furnace is used to prepare small samples of rare metal alloys, such as neodymium.

SPECIFICATION:

Features	8" Vacuum tube with one end closed and sealed flange is inserted into a vertical muffle furnace Tungsten electrodes generate arc plasma inside graphite crucible to mel material up to 2000oC A secondary material feeding device is included to add materials during arc melting The vertical box furnace will heat the quartz chamber to 1100oC to keep the melt sample hot Please click the picture left to see the detail
