Abstract

A coffin-shaped structure induction coil comprises a shaping framework and two copper tubes, wherein the cross section of the shaping framework is of a coffin-shaped structure with square planes on three surfaces and a convex arc surface at the top, meanwhile, F-shaped connection tubes are arranged at a head position and a tail position of a corresponding furnace body of the shaping framework andare opposite to each other, two connectors, arranged in the same direction, of the F-shaped connection tubes are respectively connected with each of the copper tubes, the other connector perpendicularto the connector arranged in the same direction is connected with an L-shaped bending tube, a copper electrode is connected with the other end of the L-shaped bending tube, head parts and tail partsof the two copper tubes are respectively connected with the F-shaped connection tubes and are fixed outside a surface of the shaping framework, and middle parts of the two copper tubes are arranged inparallel and are wound around the shaping framework. The coffin-shaped structure is simple in technology and is convenient to process and easy to assemble, and the problem that insulation and fireproof bricks at the top of an original medium-frequency induction horizontal sintering furnace or a medium-frequency induction horizontal graphitization furnace can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency horizontal graphitization sintering equipment, in particular to a coffin-shaped structure induction coil applied to a horizontal structure furnace body. Background technique [0002] The relationship between the medium frequency induction heating coil and the object to be heated (magnetic permeability objects such as graphite crucible and tungsten crucible) is the same as the relationship between the primary side and the secondary side coil of the transformer. The magnetic field lines generated by the intermediate frequency induction heating coil through the intermediate frequency current are concentrated on the object to be heated, and the eddy current is generated by the electromagnetic induction to heat the object to be heated. [0003] At present, the induction coils of intermediate frequency horizontal graphitization furnaces generally have the following problems: [0004] 1. ...
