Application of medium frequency quenching railway flat hole round pins

Quenching liquid cooling device (can be combined with a closed-loop cooling tower to form a double-loop structure for cooling the quenching medium, the circulating medium is pure water, without scaling).

The specific process is:

The medium frequency quenching equipment is matched with the double-station vertical CNC quenching machine tool. It uses double annular narrow heating belt sensors. The workpiece is mounted on the quenching machine tool and performs uniform rotation and lifting movements (the movement speed can be steplessly adjusted).

After the workpiece is installed and clamped, just turn the inching switch and the workpiece will automatically rise into the annular induction ring. The workpiece will automatically rotate and automatically heat at a scheduled time. After being heated to the quenching temperature, it will automatically spray water for quenching. After quenching, it will automatically drop to the original position and the workpiece can be replaced manually. . The sensor can have its own water spray, so that after the workpiece is heated to the quenching temperature, the water spray solenoid valve can be automatically opened under program control to spray water, thus ensuring the depth of the quenching layer and the quenching hardness.　

It enables customers to carry out heat treatment production conveniently and quickly, saving them the trouble of choosing matching or self-made tooling equipment. In recent years, our company has promoted various complete sets of intermediate frequency quenching equipment for shafts and disks.

For medium frequency quenching of railway flat hole round pins with a diameter of 20-40mm, our company's medium frequency induction heating equipment can be selected, equipped with a vertical CNC quenching machine tool (single station or double station optional). Quenching layer 2-6mm.

The complete set of intermediate frequency quenching equipment generally includes an intermediate frequency quenching power supply, quenching machine tools, sensors, and auxiliary cooling water circulation systems and quenching liquid circulation systems.

Medium frequency quenching equipment (including quenching transformer, three sets of quenching inductors), select power 200KW.
