Strip Rolling is a commonly used process in metal fabrication. It is used to reduce the thickness of a metal strip as well as cold work it. Strip rolling involves passing the metal strip between one or two rolls. These rolls can be driven in either direction, depending on the desired outcome. The pressure exerted on the strip is known as the Roll Pressure, or the rolling load. This pressure can vary greatly, depending on the rolling process and the kind of metal being rolled.
The strip rolling process is usually driven by two large diameter cylindrical rolls. These rolls are closely spaced, allowing the metal strip to pass through. One roll is typically driven by an electric motor, while the other roll is idle. As the strip passes through, it is “squeezed” by the rollers, which causes it to become thinner. This can be repeated a number of times until the desired thickness is achieved.
The roll pressure applied to the metal strip is usually determined by the Rolling Constant, which can be determined by several factors. These include the size and shape of the rolls, the speed of the rolls and the friction of the metal against the rolls. This rolling constant helps to determine the maximum amount of stress that the metal can endure before it deforms.
In addition to using the rolling constant to determine the maximum amount of stress that can be applied to the metal, it can also be used to adjust the texture of the finished product. By applying a higher rolling constant, the metal strip will become smoother, while a lower rolling constant will create a rougher finish.
Overall, strip rolling is a very common process in metal fabrication. It is used to reduce the thickness of the metal strip, as well as to cold work it. The roll pressure can be adjustedusing the rolling constant, depending on the desired outcome. By controlling the roll pressure and the rolling constant, metal fabricators can create a variety of textures and shapes on their metal strips.
