What is thermal forging?

Thermal power forging refers to the forging products used in the manufacture of thermal power equipment, mainly including boilers, steam turbines and other components. These forgings are usually made of metal materials through the forging process, with high strength, high temperature resistance, corrosion resistance and other characteristics, to ensure the normal operation and safety of thermal power equipment has a vital role.

First, classification of thermal forgings

Thermal power forgings can be divided into many types according to different classification methods. According to the material composition, it can be divided into carbon steel forgings, alloy steel forgings, stainless steel forgings, etc. According to the use, it can be divided into blade forging, bolt forging, pipe forging and so on. Different types of forgings have different physical and chemical characteristics and are suitable for different thermal power equipment scenarios.

Second, the production process of thermal power forging

The production process of thermal power forging mainly includes heating, forging, cooling and other links. First, the metal material is heated to a certain temperature to make it plastic; Secondly, plastic deformation is carried out through forging equipment to form the required shape; Finally, after cooling treatment, the final thermal forging is obtained. In addition, some special processes such as heat treatment, surface treatment, etc. may also be applied to the manufacture of different kinds of forgings.

3. Application fields of thermal power forgings

Thermal power forging has a wide range of applications in power production. In power stations, thermal power forgings are used to manufacture core equipment such as boilers, steam turbines and generator sets. In the Marine field, it is used for the manufacture of important components such as Marine engines and boilers; In the field of mechanical manufacturing, it can be used for the manufacture of various high-strength parts. In addition, thermal power forgings are also widely used in other fields such as chemical industry and metallurgy.

Iv. Case analysis and application

Taking a thermal power station as an example, the low-pressure rotor forging of 300MW steam turbine was fractured during operation. After analysis, it is found that the main reason of fracture is the micro crack in the forging. By improving the production process and strengthening the quality control, the problem was finally solved. This case illustrates the problems that may be encountered in the production process of thermal power forgings and the corresponding solutions.

Thermal power forging is an important part in the manufacture of thermal power equipment, its quality and performance directly affect the operation effect and safety of equipment. Through the comprehensive analysis of the classification, production process and application of thermal power forgings, we can better understand their characteristics and application scenarios, and provide references for relevant industry personnel. In the future, with the continuous development of the power industry and the development and application of new materials and new processes, the performance and service life of thermal power forgings will be further improved, providing a more powerful guarantee for the stable operation of power equipment.
