Adjust the tempering process after quenching of the high-frequency machine.
After induction quenching, the workpiece still needs to undergo tempering treatment. The purpose of this is to reduce brittleness, avoid the generation of quenching cracks, and help lower the quenching stress of the workpiece, allowing it to better achieve the required hardness. Generally, there are about three types of tempering processes for workpieces after high-frequency induction quenching: induction tempering, self-tempering, and furnace tempering.
1. Induction Tempering
1. Advantages: High-frequency induction heating equipment is small in size, environmentally friendly and energy-saving, and shortens the production cycle. It can also complete the quenching and tempering process in one loading and unloading operation, making it suitable for assembly line production.
2. Process: It uses the original quenching induction heating device to reduce power for tempering treatment of the workpiece.
2. Self-Tempering
1. Self-Tempering: The workpiece uses residual heat from its core to heat and temper the surface of the hardened layer.
2. Advantages: Environmentally friendly and energy-saving, reduces labor costs, and eliminates the need for a separate tempering device; it is timely. After high-frequency induction quenching, workpieces generally require timely tempering to prevent cracking due to delayed tempering.
3. Applicability: The self-tempering process is suitable for manufacturers with large-scale production because it only applies to workpieces that have sufficient residual heat in their cores after heating and can evenly transfer this residual heat to every point on the hardened layer.
Otherwise, after self-tempering, there will be inconsistent hardness across different areas of the quenched surface; the hardness at the junction between hardened and non-hardened surfaces will be higher than that in the central area. In severe cases, some areas may not undergo self-tempering.
3. Furnace Tempering
1. Purpose
The general purpose of performing a tempering process on a workpiece is to avoid cracks caused by excessive stress after using high-frequency induction quenching.
2. Scope of Application
However, this method is more suitable for liquid quenched or oil-quenched workpieces or small components. The tempering temperature is determined based on technical requirements of the workpiece during furnace treatment.

With the continuous progress of China's oil industry, the number of shallow oil fields has been shrinking, while heavy and deep oil fields have become the main oil wells for oil production. High-strength sucker rods for heavy and deep oil fields are playing an increasingly important role in oil production operations. Compared with ordinary sucker rods, their long service life and good performance have overwhelming advantages in resource saving, energy consumption and replacement frequency.
