High-frequency quenching equipment can rapidly heat the metal material locally or completely

High-frequency quenching equipment quickly induces a large eddy current inside the metal material in the alternating magnetic field, so that the metal material heats up until it melts. Heat up quickly.

Inductor is an important part of high-frequency quenching equipment, and the heat treatment of workpiece is mainly carried out through it. It mainly relies on the middle double strip to heat the parts, the current is distributed on the outside, the inductor generates a stronger magnetic field than the original single-turn inductor, and the effective part can obtain a larger proportion of voltage compared with the conductive part, and at the same time can obtain more Good anode current and grid current ratio, so that the output power of the equipment can meet the quenching requirements of the parts, improve the heating efficiency and save energy.

In the annealing process of high-frequency quenching equipment, pearlite transformation occurs. The main purpose of annealing is to make the external structure of the metal reach or close to the equilibrium state, in preparation for subsequent processing and final heat treatment. Stress relief annealing is an annealing process that is stopped in order to eliminate the residual stress formed due to plastic deformation processing, welding, etc. and existing in the casting.
