Abstract

The invention provides a plasma arc magnetic rotary gasification pulverizing furnace. The plasma arc magnetic rotary gasification pulverizing furnace comprises a crucible, a dust collection cover, a magnetic coil, a first electrode, a second graphite electrode, a direct-current voltage output device and an air draft device, and the dust collection cover is arranged on one side of the opening of the crucible; the dust collection cover is communicated with the air draft device through a pipeline; a gap is reserved between the dust collection cover and the opening of the crucible; and the first electrode and the second graphite electrode are arranged on one side of the concave surface of the dust collection cover and in a space surrounded by the crucible, the first electrode and the second graphite electrode are electrically connected with the direct-current voltage output device, the magnetic coil surrounds the outer side of the crucible, and a circuit formed by the first electrode and the second graphite electrode is connected with the magnetic coil in series or in parallel. According to the pulverizing furnace, the magnetic coil is arranged outside the crucible, the generated rotating magnetic field enables plasma electric arcs to be more stable and energy to be more concentrated, the influence of an oxidation layer and oxidation slag on the product quality is effectively avoided, and the uniformity of the particle size of nanoscale oxidation powder is improved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a plasma arc magnetic rotary gasification powder making furnace. Background technique [0002] Nanotechnology is a major pillar of current social and economic development. The research and development of nano products has higher requirements for production equipment. The existing gasification pulverizing furnace will produce oxide layer and oxidized slag in the furnace body during the metal melting process. Oxidation The layer and oxide slag will float on the surface of the metal melt, which will reduce the production capacity of the gasification pulverizer, and will reduce the quality of the product, resulting in a decrease in the uniformity of the particle size of the product. Contents of the invention [0003] The object of the present invention is to provide a plasma arc magnetic rotary gasification pulverizing furnace to overcome the shortcomings of the prior art...
