Forged Discs Solutions

There are inevitably metallurgical defects, such as inclusions and porosity, in the steel ingot. During the upsetting process, the severe deformation of forged discs can cause the inclusions in the ingot to be distributed in a sheet shape. The pores and porosity cannot be effectively forged, leading to unqualified ultrasonic testing and scrapping. This phenomenon of scrapping is common due to defects such as flaky distribution of inclusions and porosity that cannot be forged. Jihua has solved the issue of the qualification rate for large forged discs by improving the process. We have produced thousands of high-quality large forged discs, helping customers achieve huge economic benefits.

What are forged discs?

Forged discs are discs, wheels, covers, and other pie-like shapes of forgings; the one-way forging ratio is large, and the metal flow line is more parallel to the upper and lower planes.

Types of forged discs

Several types of forged discs are designed for specific applications and industries. The most common types include:
Flat Forged Discs
Their flat surfaces and uniform thickness characterize flat forged discs. They are used in applications where the disc needs to provide a consistent, stable base for other components. Common applications for flat forged discs include flanges, valve bodies, and heavy machinery components.
Contoured Forged Discs
Contoured forged discs have a non-uniform thickness and are shaped to meet specific design requirements. This type of forged disc is commonly used in aerospace and automotive applications, where the disc needs to conform to the contours of the surrounding components for improved aerodynamics and weight reduction.
Stepped Forged Discs
Stepped forged discs feature multiple thickness levels across the disc’s diameter, increasing strength and rigidity in specific areas. These discs are often used in heavy machinery and high-pressure applications, where the disc must withstand significant forces and stresses.
Hollow Forged Discs
Hollow forged discs have a central cavity, reducing the overall weight of the component while maintaining its strength and rigidity. Hollow forged discs are commonly used in aerospace and automotive applications, where weight reduction is crucial for improved performance and fuel efficiency.

Materials Used in Forged Discs

Forged discs can be made from various materials, each with unique properties suited for specific applications. Some common materials include:

Dimensions of Forged Discs

The dimensions of forged discs play a significant role in determining their overall performance, functionality, and compatibility with specific applications. Proper dimensions ensure the disc fits perfectly within its intended environment, allowing for seamless operation and optimal performance.
Diameter: One of the most critical dimensions of a forged disc is its diameter. Depending on the application, the diameter can range from small sizes, such as 2 inches, to large sizes, such as 144 inches.
Thickness: The disc’s thickness is another vital dimension, directly impacting its strength, rigidity, and overall durability. Thicker discs are better suited for heavy-duty applications, while thinner discs are ideal for lightweight applications.

The Forging Process of forged discs

the forging process of forged discs - Forged Discs

20230407151354 48058 - Forged Discs

Forged Discs are solid forgings, typical forgings forged on hydraulic presses that require direct forging and forming with high-quality large steel ingots. The forging process of large Forged Discs is traditionally one of the most difficult forging technologies to master in large forgings because the ingots have their inherent defects, such as segregation, inclusions, looseness, coarse columnar crystals, etc.; with the improvement of metallurgical quality, these defects can be reduced, but not eliminated. This results in the actual production of ultrasonic flaw detection once the pass rate is below 50%, high scrap rate, high production costs, and large losses for enterprises. The traditional cake forging technology is confined to the inherent upsetting – drawing length – upsetting forming process concept based on continuous process improvement. However, the pass rate of forgings has improved, in general, because there is no breakthrough in the original process, subject to the Traditional process’s inherent defects, too many factors affecting the process parameters, difficulty to master, forging quality fluctuations, and did not fundamentally solve the forging process problems of this type of forgings. Forged Discs are conventionally forged into many dense defects within a certain distance from the center; the defects are transverse cracks, with no white spots, caused by intense shear deformation in the metal weakness, for inclusions type cracks. Forging process, due to the traditional Forged Discs final forming process is upsetting forming, general upsetting is relatively large, especially in the heart of the deformation is intense, the strain state for the longitudinal compression, two-way stretching, the formation of streamlined inclusions formed by the former pulling length of compression deformation and the formation of lamellar inclusions, increasing the area of inclusions and inevitably become lamellar, that is, the subsequent upsetting deformation destroyed the former pulling length of the inclusions on the Inclusion refinement and dispersion effect, reflected in the ultrasonic flaw detection results in the heart of a certain area showing large dense defects, failing ultrasonic flaw detection.

Forged Discs Solutions

We offer a large Forged Discs forging process that does not present large dense defects in the core area of the forged part and improves the quality of the part.
The technical solution used to achieve the above purpose is a large Forged Discs forging process, characterized in that the forging process is carried out in the following steps in particular:

  • Step 1: Heating the ingot to be forged according to the material of the ingot and holding it so that the temperature of the heart of the ingot is the same as the external temperature and the ingot is uniformly heated through;
  • Step 2: The ingot is drawn to length using the existing forging method with an anvil width ratio of 0.8-0.9; each press-down rate is at least 20%, and the ingot is drawn to length in one pass; then the square stage is entered: the WHF forging method, the SUF forging method or the TER forging method is used, and the forging is carried out using the staggered anvil drawing process: the first plane is first forged on the ingot along the length of the ingot, and then this first plane is placed on the anvil, forging a second plane parallel to the first plane on the ingot, then placing the ingot on the anvil so that the two planes already forged are perpendicular to the anvil surface, forging a third plane perpendicular to the first plane, after which the third plane is placed on the anvil, and a fourth plane is forged;
  • Step 3: Forging the flat square in the height direction using the wide anvil forging method with an anvil width ratio of 0.8-0.9 to form the billet;
  • Step 4: Calculating the undercut dimensions based on the weight of the forging and making the length-to-billet width ratio of the billet obtained by undercutting ≤ 1.5;
  • Step 5: Forging the billet into a square according to the existing forging method, then inverting the octagon, and finally inverting the round to obtain a semi-finished product;
  • Step 6: Forging and forming the semi-finished products according to the existing forging method to obtain large Forged Discs.

The forging process is completely different from the existing Forged Discs forging process route. Various special forging methods are used to compact and forge through the billet during the drawing length process. The previous forging organization and flow lines are retained in the subsequent upsetting forming without destroying the flow lines, making full use of the flow lines formed by the previous drawing length, which fundamentally solves the technical difficulties of tube plate forging. The process route is simple, the technology is reliable, the ultrasonic flaw detection rate of forgings is close to 100%, and the mechanical properties are excellent, which can fully meet product performance requirements.
