I. Types of quenching and cooling equipment

Quenching and cooling equipment mainly includes the following types:

1. Oil quenching machine: using liquid oil medium for quenching, it is more uniform than air cooling and water cooling, but care should be taken to prevent fire caused by excessive oil temperature.

2. Water quenching machine: using water medium for quenching, the cost is low, but the metal material after quenching is prone to cracks.

3. Gas quenching furnace: using gas medium for quenching, such as nitrogen, helium, etc., can avoid oxidation of metal materials, but the quenching speed is slow.

4. Salt bath quenching furnace: using salt bath for quenching, quenching can be performed at a lower temperature, but attention should be paid to the corrosiveness of the salt bath.

5. Vacuum quenching furnace: quenching in a vacuum environment can avoid oxidation and contamination of metal materials, but the equipment cost is high.

2. Application of quenching and cooling equipment

Quenching and cooling equipment is widely used in the processing of various metal materials, such as:

1. Auto parts: The engine, transmission system and other parts of the car need to be quenched to improve their hardness and strength.

2. Tool manufacturing: Steel tools need to be quenched to improve their hardness and wear resistance.

3. Machinery manufacturing: Various mechanical parts need to be quenched to improve their service life.

4. Metal material production: Quenching treatment can improve the mechanical properties of metal materials, such as forging, rolling, etc.

In short, quenching and cooling equipment is an indispensable part of metal processing. Different types of equipment are suitable for different metal materials and processing requirements. Quenching treatment can improve the hardness and strength of metal materials and extend their service life.
