Combined Roll
A combined roll is a roller which is used for rolling and forming heavy plates, strips and bars. It is composed of two or more rolls which are arranged in a series to provide more strength and stability to the material during the rolling process. Combined rolls are widely used in steel, aluminum and other metal forming processes.
The two most common types of combined roll are double roll and tandem roll. Double roll are two rolls arranged in a parallel arrangement. This allows the product to be rolled on both surfaces at the same time, thereby improving work efficiency compared to single rollers. In addition, this type of roll can produce a much better surface finish and uniform thickness compared to a single roller. Tandem roll is two rolls arranged in a series or a line, each roll acts as an independent roller in the series. The product is rolled on each roll while moving through the series. This process helps to improve the uniformity of the product thickness and other surface properties.
Combined roll is ideal for large-scale production of products such as sheet metal and heavy plates. The combined roll also provides a constant pressure over the entire product, which can produce a better quality end product. The use of a combined roll also helps to reduce the amount of set-up time and material handling costs.
The selection of a combined roll is critical, as the wrong combination of rolls can result in poor product quality and increased operational costs. The rollers should be selected according to the size and shape of the product, as well as the severity of the rolling process. The rolls should also be selected according to their coefficient of friction, which affects the strength of the material and its final thickness.
Combined roll is essential for the production of high-quality products for wide range of industries. The combination of two or more rolls increases the efficiency and effectiveness of the Rolling process, helping to reduce costs and improve product quality.
