What is the production process of railway forgings?

The production process of railway forgings is a complex and fine process, which needs to go through many steps and links. The following are the general steps of the railway forging production process:

Raw material preparation: The production of railway forgings requires the use of high-quality raw materials, including steel, alloy steel, etc. The preparation of raw materials includes the selection of suitable materials, cutting, grinding and other pretreatment work.

Mold preparation: According to the design requirements of forging, manufacture the corresponding mold. Mold manufacturing needs to go through a number of steps, including design, material selection, processing, assembly, etc.

Blank preparation: The raw material is put into the mold and the blank is prepared. Billet preparation needs to ensure that the shape and size of the billet meet the design requirements.

Heating and forging: the blank is heated and then placed into the forging equipment for forging. It is necessary to control the forging temperature and forging force in the forging process to ensure the quality and performance of the forging.

Cooling and processing: After forging is completed, the forging is cooled and the necessary processing and dressing are carried out.

Quality testing: Quality testing of forgings, including appearance testing, size testing, mechanical properties testing, etc. Only forgings that meet the quality requirements can enter the next process.

Painting and packaging: Qualified forgings are painted and packaged to prevent damage during transportation.

The production process of railway forgings is a delicate and complex process, each step requires strict quality control and technical requirements. At the same time, due to the importance of railway forgings, various inspections and tests are also needed in the manufacturing process to ensure its quality and reliability.
