Description

Induction coil tool for local tempering

Technical Field

The utility model belongs to the technical field of the response tempering installation, concretely relates to induction coil frock is used in local tempering.

Background

The induction tempering is to utilize the electromagnetic induction method to generate current in the heated workpiece, and the heating tempering is realized by the energy of the eddy current, so that the heating depth is larger than the depth of the quench hardening layer in order to reduce the tensile stress of the transition layer. Therefore, for continuously heating and quenching workpieces, lower current frequency or smaller specific power is needed, tempering time is prolonged, and the heating layer is thickened by utilizing heat conduction of the workpieces. For the workpiece which is heated and quenched once, the heating layer can be thickened by an intermittent heating method. Because the induction heating tempering time is short, the tempering heating temperature should be properly increased. The workpiece after surface quenching is inductively heated, and furnace tempering, self-tempering or induction tempering can be adopted. The induction tempering device can be used for locally tempering the workpiece and accurately heating the part of the workpiece needing quenching, particularly under the conditions of adopting a magnetizer and using high power density.
