As an important machining method, forging has been widely used in many fields. Improving forging quality is one of the keys to ensure product quality and reduce cost. The following will talk about how to improve the quality of forgings from several aspects such as raw material selection, forging process and follow-up treatment.
First, raw material selection
The selection of appropriate raw materials is the basis to ensure the quality of forging. When selecting materials, it is necessary to ensure that their chemical composition and mechanical properties meet the requirements, and try to avoid harmful impurities such as oxygen, sulfur and phosphorus. In addition, for high-quality forgings, you can consider the use of vacuum smelting, electromagnetic stirring and other technologies to further purify raw materials.
Two, forging process
Good forging process is one of the keys to ensure the quality of forging parts. In the forging process, the following points should be noted:
1. Reasonable choice of temperature: too high temperature is easy to lead to solubility rise, grain growth and other problems, too low temperature will lead to deformation resistance, easy to crack and other problems. Therefore, it is necessary to choose the forging temperature reasonably according to factors such as material type and geometry.
2. Reasonable control of deformation: excessive deformation is easy to lead to problems such as uneven internal organization and porosity, and too small deformation will affect mechanical properties. Therefore, it is necessary to reasonably control the amount of deformation according to factors such as material type and geometric shape.
3. Pay attention to forging speed: too fast forging speed can easily lead to poor surface quality, and too slow will affect production efficiency. Therefore, it is necessary to improve the forging speed as much as possible under the premise of ensuring quality.
Iii. Follow-up treatment
The subsequent treatment of forgings is also of great help to improve the quality of forgings. Proper heat treatment, machining and surface treatment can improve the performance of forgings. Among them, the common follow-up treatment methods include quenching, tempering, surface spraying and so on.
To sum up, improving the quality of forgings requires comprehensive optimization in raw material selection, forging process and subsequent treatment. Only by constantly improving the level of production technology and technology can we produce higher quality forgings and remain invincible in the market competition.
