1. Introduction

The surface quality of forged parts is affected by many factors, such as the production process of the forging parts, the chemical composition of the forging blank, and the quality of the forging tools, etc. Among them, the quality of the forging blank (prior to machining) plays an important role in determining the surface quality of the final forged part. In this paper, the effect of the forging blank on the surface quality of forged parts shall be discussed.
3. The Quality of the Forging Blank

The quality of the forging blank affects the surface quality of the final forged parts in a variety of ways. First of all, the chemical composition of the forging blank determines the physical properties of the forged part, such as strength, toughness, and ductility. In order for a forged part to have a good surface quality, its physical properties need to be within certain limits. Secondly, the forging blank can affect the surface quality of the forged part as it is deformed under extreme thermal and mechanical conditions. During the forging process, the forging blank undergoes large strains which can lead to surface defects such as cracks and inconsistencies. Finally, the quality of the forging blank can also affect the surface finish of the forged part. If the blank is too soft, it might not be able to sustain the extreme temperatures and pressures during the forging process, resulting in a poor surface finish. On the other hand, if the blank is too hard, it can lead to surface roughness.
4. Quality Requirements for Forging Blanks

In order to ensure good surface quality in the final forged part, the forging blank must meet certain quality requirements. Firstly, the chemical composition of the forging blank must be inspected to ensure that it is suitable for the desired application and has the desired properties. This includes ensuring that the material contains the required levels of carbon, alloying elements, and other elements, as well as that it is within certain range limits. Secondly, the surface of the forging blank must be checked for any surface defects that may be present prior to forging. This includes checking for cracks, pits, and other surface irregularities.
Once these requirements are met, the forging blank can then be subjected to the forging process. During the forging process, the blank will be subject to very high temperatures and pressures. As a result, it is important to use quality equipment and tools to reduce the risk of surface defects caused by these extreme conditions.

In conclusion, the surface quality of forged parts is greatly affected by the forging blank. The forging blank must meet certain quality requirements in order to ensure good surface quality in the final forged part. Additionally, it is important to use quality forging tools and equipment in order to reduce the risk of surface defects caused by the extreme conditions during the forging process.
