- Q:How are steel billets rolled or forged into other shapes?
- Steel billets can be transformed into various shapes through a process called rolling or forging. Rolling involves passing the heated billet through a series of rollers that apply pressure to reshape the material. This process is often used to produce long and flat shapes such as sheets, plates, and bars. During rolling, the billet is first heated to a specific temperature to make it more malleable. It is then fed into the rolling mill, where a pair of rotating rollers exerts pressure on the billet to reduce its thickness and elongate it. The rollers can be smooth or grooved, depending on the desired shape of the final product. The billet is passed through the rollers multiple times, gradually reducing its thickness and lengthening it. This process can be repeated with different sets of rollers to achieve specific dimensions and cross-sectional shapes. The final product is then cooled and cut to the desired length. Forging, on the other hand, involves applying compressive forces to the heated billet to shape it into various forms. There are two main types of forging processes: open-die forging and closed-die forging. In open-die forging, the heated billet is placed between two flat dies, and a hammer or press applies pressure to deform the material. The billet is repeatedly struck or pressed until it takes the desired shape. This process is commonly used for producing large and complex shapes such as crankshafts, connecting rods, and turbine discs. Closed-die forging, also known as impression-die forging, involves using two or more dies with cavities that mirror the desired shape of the final product. The heated billet is placed between the dies, and pressure is applied to force the material into the cavities, filling them completely. This process is often used to produce smaller and more intricate shapes like automotive parts, hand tools, and fittings. Both rolling and forging processes require the billet to be heated to a specific temperature to make it more ductile and easier to shape. The choice between rolling and forging depends on factors such as the desired shape, size, and mechanical properties of the final product.
