What kinds of cutting methods for hot forging

The forging process performed above the recrystallization temperature of the metal is called hot forging. Hot forging is also called hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the die is long. Therefore, the mold material is required to have high thermal stability, high-temperature strength and hardness, impact toughness, thermal fatigue resistance and wear resistance, and easy processing. Light-duty hot forging dies can be made from low alloy steels.

Determination of the scope of hot forging

Hot forging is carried out within a certain temperature range. The forging temperature range of steel refers to the temperature range between the starting forging temperature (initial forging temperature) and the ending forging temperature (final forging temperature).

Two principles of hot forging

1. The principle of induction electric heating of hot forging.Under the action of the alternating magnetic field generated by the induction of the alternating current, alternating eddy currents are generated inside the metal blank. The metal blank is heated directly due to eddy currents and magnetization heating (below the magnetic transition point).

 The heating method of hot forging

​​​​​​​The hot forging manufacturer tells you that the purpose of heating the metal blank before forging is to improve the plasticity of the metal, reduce the deformation resistance, make it easy to flow and form and obtain a good forging structure. The hot forging manufacturer tells you that heating before forging has a direct impact on improving forging productivity, ensuring forging quality and saving energy consumption. According to the different heat sources used, the heating methods of metal blanks can be divided into two categories: flame heating and electric heating.

Several processing methods of hot forging

​​​​​​​1. Break. The hot forging manufacturer tells you that this method of breaking is suitable for high carbon steel and high alloy steel with higher hardness. The hot forging manufacturer tells you that bearing steel such as GCr15, GCr15SiMn, GSiMnMo, GSiMnV, etc., the heating temperature is 300 ~ 400 ℃.

How do FORGINGS compare to Castings?

Forgings are stronger. Casting cannot obtain the strengthening effects of hot and cold working. Forging surpasses casting in predictable strength properties – producing superior strength that is assured, part to part. Forging refines defects from cast ingots or continuous cast bars. A casting has neither grain flow nor directional strength and the process cannot prevent the formation of certain metallurgical defects. Pre-working forge stock produces a grain flow oriented in directions requiring maximum strength. Dendritic structures, alloy segregation, and like imperfections are refined in forging.
