Abstract

The invention discloses a roller type permanent magnet heating system. The roller type permanent magnet heating system comprises a permanent magnet roller, a rolling locating device, a heating locating device and a driving device, wherein a plurality of permanent magnets are arranged on the inner wall of the permanent magnet roller, the rolling locating device is used for locating the roller, and the heating locating device is used for locating a metal heating piece. The permanent magnets rotate around the metal heating piece. The permanent magnets generate a rotating magnetic field. The rotating magnetic field acts on the metal heating piece, so that an eddy current is generated in the metal heating piece, heat is generated, and heating is achieved. By the adoption of the roller type permanent magnet heating system, a huge transformer system needed by a traditional electric induction heater, is not needed; in addition, the permanent magnets are arranged on the inner wall of the roller, the metal heating piece is arranged in an inner cavity of the roller, in this way, when the roller rotates, the permanent magnets surrounding the inner wall of the roller can be driven to rotate around the metal heating piece, no-dead-angle heating is achieved, and the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of metal heating, in particular to a drum type permanent magnet heating system. Background technique [0002] In the field of metal heating, especially non-ferrous metal heating, there are the following traditional heating technologies: [0003] 1. Gas heating, using the heat generated by burning natural gas or gas to heat metal. Under this heating technology, it is difficult to precisely control the heating temperature of the metal, and it is not easy to heat a metal round ingot with a larger diameter, such as a metal ingot above φ12. [0004] 2. Resistance furnace heating. The resistance furnace uses electricity as the heat source. The electric energy is converted into heat energy through the electric heating element, and the metal is heated in the furnace by thermal radiation or hot air convection. In this heating technology, a large amount of energy is consumed on electric heating elements such as resistance wir...
