Arc Melter
Centorr Series 5BJ Arc Melting Furnace
A plasma arc melter operates on principles similar to an arc-welding machine, where an electrical arc is struck between two electrodes. The high-energy arc creates high temperatures ranging from 3,000 degrees to 7,000 degrees Celsius. The ”plasma” is highly ionized gas which can be directed in a controlled manner onto a material specimen.
The Centorr Series 5BJ Single Arc furnace consists of a water-cooled stainless steel Bell Jar hinged from a fixed baseplate. Clamps are provided for operation at slightly positive pressure. The electrode (stinger) shaft penetrates down through the Bell Jar top, directed toward the hearth, which is water-cooled copper with an interchangeable top surface. Because of its simplicity, ease of access into the furnace, and small volume, the furnace is easily purged. Work specimens are, therefore, very quickly prepared and a very high degree of purity is maintained.
Various configurations of cavities can be provided in the hearth top surface. Light and window are provided for observation inside the Bell Jar. The stinger is sealed to the Bell Jar top by means of a ball joint and stainless steel bellows. Pressure compensation for "zero feel" is incorporated into the design of this seal. Provision is made for attachment to a vacuum pump for evacuation prior to back-filling with inert gas. Also included are ports and gauges for inert gas.
