Abstract

The invention discloses a steel wire induction-heating device. The steel wire induction-heating device comprises a worktable, and a plurality of cylindrical induction coil formed by winding hollow copper pipes; a plurality of supporting plates are detachably mounted on the worktable; each induction coil is fixedly mounted on one supporting plate; the induction coils are coaxially connected in series; an insulating tube is arranged inside each induction coil, and a round steel wire to be heated is put into the insulating tube; the wall thickness of each insulating tube is 2-3mm, the distance between the inner wall of each induction coil and the outer wall of each insulating tube is 3-4mm, and the distance between the inner wall of each insulating tube and the outer wall of each steel wire to be heated is 2-3mm. Compared with the prior art, the steel wire induction-heating device is reasonable in design, flexible in use, safe and reliable, and capable of meeting a plurality of processing requirements; in addition, the dimensions of the diameter of each steel wire and the inner diameter of each induction coil are reasonably matched, so that the distance between the steel wire and the induction coil can be reduced, and furthermore, the heating efficiency and the heat treatment quality of the steel wire can be improved.

Description

technical field [0001] The invention relates to a steel wire induction heating device, which belongs to the technical field of steel wire thermal processing. Background technique [0002] In the process of special steel processing, it is necessary to quench the steel, that is, to heat the steel to a temperature above the critical temperature, keep it warm for a period of time, make it austenitized in whole or in part, and then quickly cool it at a cooling rate greater than the critical cooling rate. transformation to bainite or bainite to increase the hardness and wear resistance of the steel. At present, the steel wire is mainly heated by an inductor on the production line. Induction heating is to heat the steel wire as a whole through the eddy current in the steel wire generated by the alternating magnetic field of the inductor, so that the core and surface temperature of the entire steel wire are approximately equal. The diameter of the induction coil on the existing pro...
