2 天之前The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is Roll pass design optimisation SpringerLink

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability Medium and heavy plates are important strategic materials, which are widely used in many fields, such as large ships, weapons and armor, large bridges, and super high-rise buildings. However, the traditional control technology cannot meet the high-precision control requirements of the roll gap of the thick plate mill, resulting in errors in Biomimetics Free Full-Text Optimization Strategy of Rolling Mill

rolling mill thus helps in reducing the size of a metal thereby molding it into the desired form and shape. Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are frequently categorizedDescription. Fundamentals of Rolling presents the theoretical knowledge of longitudinal rolling in a comprehensive procedure. This book discusses the basic theory and principles of rolling processes.

The more roll pairs the mill has, the greater the size reduc-tion it can achieve. For instance, reducing salt feedstock to coarse road salt requires a roller mill with one roll pair, while reducing the material to table salt requires a mill with two or three roll pairs.

At least, more than 95% of the ferrous and non-ferrous metals are processed to desired shapes through rolling. These desired metal shapes include plates, foil, strip and various sections such as bars, beam, rail and seamless pipe.
