Quenching is a heat treatment process in which steel is heated to a temperature above the critical temperature, held for a certain period of time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure mainly composed of martensite (or bainite or single-phase austenite is obtained as necessary). Quenching is the most widely used work technology method in the heat treatment process of steel.

The process requirements for spring production require that the spring wire used be in accordance with the customer's order, including the wire surface hardness. After the steel wire is heated to a certain temperature in the heating furnace, continuous and stable quenching treatment is required to be carried out, so that the surface hardness of the steel wire is ensured. The quenching treatment of the steel wire in the quenching oil always ensures that the steel wire is positioned at the corresponding depth below the liquid level of the quenching oil, thus ensuring that the steel wire has uniform hardness after quenching.

In the actual quenching process, the steel wire often floats out of the quenching oil liquid level or changes the depth below the quenching oil liquid level, so that the depth of the quenching steel wire at the quenching oil liquid level is easy to change continuously, the steel wire cannot be ensured to be always at the same quenching oil depth, and the hardness of the quenching steel wire is uniform.

If the hardness of the steel wire is uneven in the spring winding process, the spring can present an irregular shape, and the reject ratio is increased.
