Closed-die forging, also called impression-die forging, entails shaping the steel within a set of dies that contain the desired shape. The metal is placed between the dies and compressed under high pressure. Closed-die forging is often used for smaller, more intricate components, providing greater control over the final shape and dimensions. 3. Roll forging involves passing the steel between two or more rotating rolls to shape it. The rolls exert pressure on the metal, causing it to deform and acquire the desired shape. This technique is commonly used for producing long, cylindrical components such as axles, bars, or rings. 4. Upset forging involves deforming the steel by reducing its length and increasing its cross-sectional area. The metal is placed between two dies and axially compressed, resulting in bulging and the desired shape. Upset forging is commonly utilized for producing short, thick components like bolts, screws, or nuts. 5. Press forging, similar to closed-die forging, employs a hydraulic or mechanical press to shape the steel. The metal is placed between two dies and compressed under high pressure, allowing controlled deformation. Press forging enables precise control over the shaping process and is often employed for producing high-quality and complex components. Each of these forging techniques possesses its own advantages and limitations, and the choice of technique relies on factors such as size, complexity, and desired properties of the final product. By selecting the appropriate forging technique, manufacturers can ensure that special steel components meet the required specifications and performance standards.
