Basic introduction of rail plate forging
Aug 31, 2022| Basic introduction of rail plate forging
A processing method of using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size. One of the two major components of forging. After forging, the as-cast looseness and welding holes of the metal can be eliminated, and the mechanical properties of the forgings are generally better than those of the castings of the same material. For the important parts in machinery with high load and severe working conditions, forged parts are mostly used except for rolling plates, profiles or welded parts with simpler shapes.

Forgings can be divided into:
1. Open forging: The impact force or pressure is applied to deform the metal between the upper and lower irons to obtain the required forgings. The forging ratios mainly include manual forging and mechanical forging.
2. Closed-form forging: Forgings are obtained by pressing and deforming metal blanks in a forging die cavity with a certain shape, which can be divided into die forging, cold heading, rotary forging, extrusion, etc. According to the deformation temperature, forging can be divided into hot forging (processing temperature is higher than the recrystallization temperature of the billet metal), warm forging (lower than the recrystallization temperature) and cold forging (normal temperature).
The materials used for forgings are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, titanium, copper, etc. and their alloys. The original state of the material includes bar, ingot, metal powder and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the cross-sectional area after deformation is called the forging ratio. The correct choice of forging ratio has a lot to do with improving product quality and reducing costs.
The track pressure plate is an important component of the railway track, and the track referred to here has many components.
As an integral engineering structure, the track is laid on the roadbed, which plays a guiding role in the operation of the train, and directly receives the super pressure of the rolling stock and its load. Under the power of the train's operation, its various components must have sufficient strength and stability to ensure that the train runs safely, smoothly and discontinuously at the specified speed.
