What is a forged rotor?
A forged rotor refers to a rotating body supported by bearings. Objects such as optical discs that do not have their rotating axis can be considered forged rotors when they are rigidly connected or have additional axes.
Types of forged rotors
Several types of forged rotors are designed to cater to specific requirements and applications. In this section, we will discuss the most common types of forged rotors:
One-Piece Forged Rotors
One-piece forged rotors are crafted from a single piece of metal, typically high-grade steel or aluminum alloy. These rotors offer a perfect balance between performance, durability, and cost-effectiveness. They suit most street and track applications, including sports cars, high-performance sedans, and track-focused vehicles.
Two-Piece Forged Rotors
Two-piece forged rotors have a separate hub and rotor surface connected by bolts or pins. This design allows for improved heat dissipation and reduced weight compared to one-piece rotors. Two-piece forged rotors are favored in high-performance applications, such as professional motorsports, where weight reduction and thermal efficiency are critical.
Slotted Forged Rotors
Slotted forged rotors feature grooves or slots machined into the rotor surface. These slots improve heat dissipation, reduce brake fade, and enhance brake pad bite. Slotted rotors are ideal for high-performance street cars and occasional track use, where consistent braking performance is essential.
Cross-Drilled Forged Rotors
Cross-drilled forged rotors have holes drilled through the rotor surface to facilitate better cooling and gas evacuation. These rotors offer enhanced braking performance, especially in wet conditions, by helping to prevent the buildup of water and gas between the rotor and brake pad. Cross-drilled rotors suit street cars, track-day enthusiasts, and light motorsport applications.
Combination Slotted and Cross-Drilled Forged Rotors
Combination rotors offer the best of both worlds for those seeking the benefits of both slotted and cross-drilled designs. These rotors provide excellent heat dissipation and consistent braking performance, ideal for high-performance street cars and track day events.

Dimensions of Forged Rotors
The dimensions of forged rotors vary depending on the application, vehicle type, and performance requirements. However, some key dimensions to consider include the following:
-
Diameter: The rotor diameter plays a significant role in determining the braking performance, with larger diameters offering increased heat dissipation and better leverage for the brake calipers. Common rotor diameters range from 300mm to 400mm, with larger diameters typically found on high-performance vehicles and race cars.
-
Thickness: Rotor thickness is another crucial dimension, affecting heat capacity and resistance to warping. Thicker rotors can handle more heat and are less prone to warping, while thinner rotors may be more suitable for lighter vehicles or those with less demanding braking requirements. Typical thicknesses for forged rotors range from 25mm to 36mm.
-
Mounting Height: The mounting height is the distance from the wheel hub surface to the outer edge of the rotor. This dimension is important for ensuring proper alignment between the caliper and rotor and avoiding interference with other suspension components. Mounting heights can vary greatly depending on the vehicle and rotor design.
The Forging Process of forged rotors
The rotor forging of a steam turbine generator is a multi-step shaft type forging with a relatively simple shape. However, rotor forging requires good strength plasticity, uniform structure, and low ductile-brittle transition temperature (FATT). Additionally, the rotor forging usually has a large mass tonnage and high non-destructive testing technical standards. To obtain uniformly organized and high-quality rotor forging, strictly controlling the various manufacturing processes and processes is necessary. Summarize the steel ingot selection and forging process precautions for 30Cr1Mo1V steam turbine rotor forgings to improve the product quality and qualification rate.
Figure.1 30Cr1Mo1V Steam Turbine Rotor Forgings
Selection of steel ingots
Usually, rotor forgings have a large mass tonnage. Due to a large negative segregation precipitate pile at the bottom of the steel ingot, the ingot contains many non-metallic inclusions with high melting points, such as silicates. The riser end of the steel ingot is usually a gathering area of carbon, sulfur, phosphorus, and porosity. Therefore, the utilization rate of the generator rotor forgings is usually 45% -55%. The removal rate of the riser end is 5% -10%, and the removal rate of the bottom end is 10% -20%. The technical requirements for rotor forgings are high, and the effective utilization rate of steel ingots is lower than that of general forgings. The presence of non-metallic inclusions seriously affects the thermoplastic properties of the material, making it difficult for the rotor forging billet to deform at high temperatures.
Moreover, a large amount of non-metallic inclusions remain in the forging, which can initiate microcracks inside the material after subsequent heat treatment and tempering, reducing the toughness performance of the rotor material. Phosphorus increases the cold brittleness of the steel, resulting in poor weldability of the forging. Sulfur is easily combined with Fe atoms to form FeS, Causing brittle cracking of steel during hot forming.
From the analysis of accidents in foreign power plants, it can be seen that the main cause of rotor fracture is not only stress concentration, low lateral plasticity in the center area of the rotor, and high brittle transition temperature but also the presence of a large number of metallurgical defects such as inclusions and porosity in the rotor (and even white spots in some forgings). Due to the large tonnage and mass of rotor forgings, the weight of the selected steel ingot is inevitably large. As the weight of the steel ingot increases, the cooling rate of the central dendrite during solidification of the large cross-section steel ingot is slow, leading to an increase in the tendency of steel ingot composition segregation, porosity, intergranular cracks, and other defects. Therefore, reducing inclusions and ingot segregation in steel has become the first issue that should be taken seriously in producing rotor forgings. Therefore, strict requirements should be placed on the selection of raw materials, baking of furnace materials, improvement of the thermal smelting system, cleanliness of the pouring system, and reasonable chemical composition ratio of steel ingots. Currently, alkaline electric furnaces, vacuum casting technology, and later electro-slag remelting technology are widely used. Alkaline electric furnaces can obtain steel with high purity (sulfur and phosphorus less than 0.010%), and vacuum casting technology greatly reduces the hydrogen content in the steel (1.5ppm), effectively reducing the probability of white spots occurring. The steel ingot remelted by electro slag has fewer non-metallic inclusions, less chemical element segregation, and higher density. Therefore, the electro-slag steel ingot remelted by electro-slag was selected, and the ingot type used was selected φ Table 1 shows the chemical analysis results of a 500-diameter 2.5T electro-slag ingot.
Table.1 Chemical Composition Requirements (wt%)
| Element | C | Mn | Si | P | S | Cr | Ni | Mo | V | Cu | Al |
| Ingot Analysis | 0. 30 | 0.77 | 0.3 | 0. 007 | 0. 06 | 1.1 | 0.41 | 1. 10 | 0. 22 | 0.07 | 0. 008 |
Forging process of the rotor
When developing the forging process for the 30Cr1Mo1V rotor of the steam turbine in Figure 1, combined with the high utilization rate of electro-slag steel ingots and the process of rotor forging deformation, including the heating of the steel ingot, the clamping of the steel ingot, upsetting, elongation and other processes, measures were taken to cut off the bottom pad of the electro slag steel ingot and retain the arc end using a saw machine. The article mainly elaborates on the deformation of upsetting and elongation during the forging process. The heating of steel ingots adopts a method of insulation at 1180-1250 ℃ for 5-7 hours.
During the upsetting of the rotor billet, two upsets were used to fully weld the internal defects of the steel ingot, break the as-cast structure, and change the distribution of inclusions. As long as the press capacity permits, the degree of upsetting deformation can be reduced (εH) to Greater than 50%. The height-to-diameter ratio (H/D) should be as close to 0.6-0.65. Namely εH=(H0-H)/H0 x 100%>50%; H/D=0.60-0.65, where Ho is the height of the steel ingot before upsetting in millimeters; H is the height of the steel ingot after upsetting in millimeters; D is the diameter of the steel ingot after upsetting in millimeters.
Press the clamp at the arc end of the steel ingot and cut it to φ three hundred × 500, then upsetting the plate to a height of about 600, then elongating the blank to 800 square meters, then upsetting the plate to a height of about 550 square meters, elongating the blank to 400 square meters, and finally pressing the shoulder to elongate to the size of the forging. The finished product has a total forging ratio of>10, and the final forging temperature during the forging process is controlled above 850 ℃.
In the forging process of the 30Cr1Mo1V rotor, two upsets are used to increase the elongation forging ratio and weld the internal defects of the steel ingot. When the steel ingot starts upsetting due to its large height and diameter (usually around 2 for standard steel ingots), it is not transparent, and the central metal bears tensile stress. The defect not only cannot be welded but may also expand. As the alarming deformation increases, when the height-to-diameter ratio is about 1, the middle is subjected to significant compressive stress, and defects can only be welded together. During the upsetting of steel ingots, uneven deformation of the billet occurs due to friction, with a large degree of deformation in the middle and a small amount at both ends. So, the internal defects in the middle are first welded together, and as the degree of upsetting deformation increases, the defects at both ends gradually weld together. When forging a rotor, a handle is usually used for upsetting. The metal deformation near the clamp is very small, and this area has many central defects. Even if the upsetting deformation is large, it is difficult to weld. Due to uneven deformation during upsetting, the internal defects in the middle section of the steel ingot are first welded. When the upsetting deformation is sufficient, the defects are fully welded. This part is used to forge the rotor shaft, improving the forging quality. In addition, increasing the upsetting process can increase the elongation forging ratio.
Elongation deformation is one of rotor forging technology’s most basic and important operations. The forging quality of rotor forgings (such as macroscopic analysis, ultrasonic testing results, transverse and longitudinal mechanical properties, etc.) depends to a certain extent on the quality of elongation deformation. During the elongation forging of rotor forgings, factors such as the feed rate, reduction, deformation method, size, and shape of the anvil, and forging temperature during elongation deformation also have a significant impact on the quality of the rotor forgings. When a round billet is drawn on a flat anvil, especially when it is rolled, it exerts transverse stress at the center, which not only prevents welding defects but also has the possibility of producing defects at the center. Therefore, using upper flat anvils and lower V-shaped anvils in processes such as rotor pressing, forming, rounding, and correction is appropriate. Therefore, during the elongation process, try to ensure that the relative feed rate of elongation is equal to 0.5-0.8, and use full anvil feeding and high temperature and large reduction to complete the main deformation process to ensure the quality of the rotor; In the elongation process of rotor forging, the forging ratio, reduction, relative feed rate, anvil type, deformation method, etc. all seriously affect the final quality of the rotor product. When stretching, try to achieve uniform deformation of the billet and make the centerline of the forging coincide with the centerline of the steel ingot.
Post-forging heat treatment of the rotor (see Figure 2)
The 30Cr1Mo1V steam turbine rotor forging in the article has a small mass tonnage and adopts a heat treatment process of normalizing and tempering after forging. The normalizing and tempering process is 950-980 ℃ and 680-720 ℃, with a uniform structure, which prepares for the preliminary heat treatment of the subsequent rotor forging.
Figure.2 Post-forging heat treatment process for rotor forgings
The rotor is one of the key components that determine the operating speed of the steam turbine. At the same time, high-quality rotors can also improve the unit’s service life, reduce the rotor operation’s failure rate, and improve the efficiency of kinetic energy conversion. Therefore, continuously optimizing the performance of rotor products requires continuous optimization of the manufacturing process. Related manufacturing processes, such as forging, also need to be continuously optimized to improve the quality of rotor products. To improve the overall manufacturing level of the manufacturing industry.

-
Replace brake pads: Worn brake pads can compromise your braking performance and cause damage to your rotors. Monitor your brake pad thickness and replace them to maintain effective braking and prevent premature rotor wear.
-
Avoid overheating: Overheating can lead to rotor warping and reduced braking performance. Avoid excessive or prolonged hard braking, especially during spirited driving or track events, to minimize the risk of overheating.
- Keep rotors clean: Dirt, debris, and brake dust can accumulate on the rotor surface, affecting heat dissipation and braking performance. Clean your rotors with a soft brush and brake cleaner to remove buildup.
