Heat treatment process and influencing factors of shaft rings

shaft Collar is an important component in the mechanical industry, used to connect shafts and bearings, transmit motion and force. Therefore, the correct selection and use of the collar is very important. The following introduces the heat treatment process and its influencing factors of the shaft ring.

1、 Heat treatment process
The heat treatment process of the shaft ring includes annealing, normalizing, quenching, and tempering. Different heat treatment processes have different effects on the structure and properties of the shaft ring.

annealing
Annealing is the process of heating a material above a critical point, holding it for a period of time, and then slowly cooling it. Annealing can eliminate internal stress in materials, improve plasticity and toughness, and also refine the crystal structure of materials.

normalizing
Normalizing is the process of heating a material above point A, holding it for a period of time, and then cooling it in air. Normalizing can improve the hardness and wear resistance of materials, while also eliminating internal stress.

quench
Quenching is the process of heating a material above the AC1 line, holding it for a period of time, and then rapidly cooling it in oil or water. Quenching can make materials harder and more wear-resistant, while also eliminating internal stress in the material.

tempering
Tempering is the process of heating a material below the AC1 line, holding it for a period of time, and then rapidly cooling it in air or oil. Tempering can eliminate internal stress in materials, reduce their hardness and brittleness, and also improve their toughness.

2、 Influencing factors
Heating temperature and insulation time
Different heating temperatures and holding times have different effects on the effectiveness of heat treatment processes. Generally speaking, the higher the heating temperature and the longer the insulation time, the better the effect of the heat treatment process.
Cooling rate

The cooling rate also has different effects on the effectiveness of the heat treatment process. Generally speaking, the slower the cooling rate, the better the effect of the heat treatment process.
