In general, quenching is a type of heat treatment operation in which a metal material heated to a high temperature during heat treatment is quenched to cause a phase change in the metal structure for the purpose of increasing strength by improving the properties of the metal material.

In this quenching, water or oil is sprayed on the surface of the heated metal material, or it is immersed and cooled quickly.

As a prior art for such quenching, "spray quenching system for heat-treated metal products" has been proposed.

The prior art is provided with one or more spray quench rings that eject a controlled volume of coolant spray onto the workpiece passing through the quench ring. The supply of coolant to the quench ring is configured to selectively change the pressure, coolant jet discharge rate, flow rate, and coolant spray pattern onto the workpiece as the material passes through the quench ring, depending on the mass cooling requirements. It is coordinated with the control of the quenching ring.

However, in the prior art, since the nozzle is integrally formed with the quenching ring, it is impossible to control the injection position of the coolant, and there is a problem in that only the material of the specification suitable for the quenching ring can be cooled.

In addition, since there is no separate supporting structure for a material that sequentially moves a plurality of quenching rings, there is a problem in that contact with the quenching ring occurs due to the pressure of the coolant sprayed when moving a long length.
