Inductor used in quenching of large-scale forged steel supporting roll

Abstract

The invention discloses an inductor used in quenching of a large-scale forged steel supporting roll. The inductor used in the quenching of the large-scale forged steel supporting roll comprises an induction coil (1) made of a copper plate, wherein a surrounding cooling water pipe (2) is arranged at the outer side of the induction coil (1), and connecting pieces (4) used for connecting the inductor with an induction transformer are arranged at the two end parts of the induction coil (1). The inductor used in the quenching of the large-scale forged steel supporting roll comprises the induction coil made of the copper plate with a certain width, a plurality of thermometer holes formed in the induction coil, a cooling water pipe which is wound at the outer side of the induction coil and made of a plurality of square copper pipes, a cooling water pipe connector, a fixed support, an insulating plate and connecting pieces connected with the induction transformer, so that the inductor used in the quenching of the large-scale forged steel supporting roll is firm in structure and strong in induced vibration resistance, temperature can be conveniently measured, height of the inductor is increased to 200-250mm from 150-165mm in convention, heating time can be prolonged for 2-4 minutes, heating depth is increased, and depth of a hardening layer of the roll is increased.

Description

technical field [0001] The invention relates to roll induction heat treatment tooling equipment, in particular to an inductor for quenching large forged steel support rolls which is easy to manufacture, has a firm structure, is convenient for temperature measurement, and can increase the heating depth to increase the depth of the hardened layer of the roll. Background technique [0002] The principle of induction hardening is to place the workpiece in the inductor. When the alternating current passes through the inductor, an alternating magnetic field with the same frequency as the current is generated around the inductor, which runs through the metal workpiece placed in the induction coil. Correspondingly, the induced electromotive force is generated, and the electromagnetic induction generates an induced current of the same frequency, that is, an eddy current. Relying on this current and the resistance of the workpiece itself, the surface of the workpiece is rapidly heate...
