In the forging process of Incoloy 825 chilled rings, punching, reaming and ring rolling are common processing steps. The following are some common methods and precautions:
1. Punching: Punching is to punch out part of the material in the middle part of the ingot to form a central channel for subsequent processing and use. Punching needs to be done after the ingot is preheated. Punching is generally done with a die, which should match the size and shape of the ingot. During the punching process, the punching force and speed need to be controlled to avoid excessive punching or cracks.
2. Reaming: Reaming is to expand the diameter of the channel to the required size on the basis of the existing channel. Reaming needs to be done after punching. Generally, a reaming machine is used for reaming, and the reaming machine should match the size and shape of the hole. During the reaming process, it is necessary to control the reaming force and speed to avoid excessive reaming or cracks
3. Ring rolling: Ring rolling is to deform the central part of the ingot into a ring shape to form a hollow ring. Ring rolling needs to be done after reaming. The ring rolling machine is generally used for ring rolling, and the ring rolling machine should match the size and shape of the steel ingot. During the ring rolling process, the ring rolling force and speed need to be controlled to avoid excessive deformation or cracks.
It should be noted that in the process of punching, reaming and ring rolling, it is necessary to select appropriate processing equipment and methods according to the size, shape, material and requirements of the steel ingot. At the same time, it is necessary to control factors such as strength, speed and temperature during processing to ensure processing quality and efficiency. Finally, for the processed Incoloy 825 chilled ring, subsequent heat treatment and surface treatment are required to achieve the required performance and appearance quality.
Yes, the choice of hammering force and speed will be affected by the change of forging temperature. Forging temperature is one of the important factors affecting the hammering force and speed in the forging process, and different temperatures will have different effects on the selection of hammering force and speed.
Normally, as the forging temperature increases, the plasticity and forgeability of the material will increase, so it is necessary to use less hammering force and speed to avoid excessive deformation and cracking. At the same time, excessive hammering strength and speed will also make the forging temperature rise too fast, resulting in defects such as material surface burns and bubbles.
Conversely, when the forging temperature is lower, greater hammering force and speed need to be used to achieve sufficient deformation and shape accuracy. At this time, too small hammering force and speed will cause insufficient deformation of the forging and fail to meet the design requirements.
Therefore, in the forging process, it is necessary to adjust the selection of hammering force and speed according to the change of forging temperature in order to achieve the best forging effect. At the same time, it is also necessary to pay attention to controlling the stability and consistency of the hammering force and speed during the forging process to ensure the surface quality and integrity of the forging.
