Aluminium Foil for transformer manufacturers tell you that rolling is a metal plastic processing method that changes the shape and size of the metal section between the rotating rolls of the rolling mill, while controlling its microstructure and properties.

Rolling is a process in which a metal undergoes continuous plastic deformation. Its production efficiency is high, so it is a widely used plastic processing method. Rolled products account for more than 90% of all plastic processed products. Steel, non-ferrous metals, some rare metals and their alloys can all be processed by rolling. Aluminium Foil for transformer manufacturers tell you that rolling can not only change the shape and size of the metal, but also improve the initial as-cast structure of ingots and continuous casting billets, refine the grains, and improve the composition and distribution of phases, thus improving product quality. performance.
According to the configuration and rotation direction of the rolls, the movement of the rolling stock and the shape of the product, the rolling methods mainly include longitudinal rolling, cross rolling and skew rolling. According to the degree of work hardening, recovery and recrystallization of the metal during the rolling process, rolling is divided into hot rolling, cold rolling and warm rolling.
According to the different types of rolling products, rolling can be divided into billet rolling (preliminary rolling), strip and foil rolling (strip and foil production), profile and wire rolling (profile and wire production), pipe rolling (pipe production) and the rolling of special shapes such as periodic section rolling, wheel tire rolling, etc. Aluminium Foil for transformer manufacturers tell you that according to the distribution form of rolling mills, plate and strip rolling is divided into single-stand, double-stand, semi-continuous and continuous rolling. Section steel and wire rod rolling can be divided into one-line, two-line, multi-line, in-line tracking, checkerboard, semi-continuous and continuous rolling (section rolling mill).
Rolling is the main processing method for metallurgical enterprises to produce steel and non-ferrous metal products. The main products of the system are thick steel plate, strip steel, thin plate, foil, and commonly used section steel includes square steel, round steel, flat steel, angle steel, I-beam, channel steel, etc. Steel piles, flat bulb steel, window frame steel, etc., as well as special-shaped section steel, periodic section or special section steel; steel pipes include round pipes, some special-shaped steel pipes and variable-section pipes. Non-ferrous metal materials mainly include plates, strips, foils and various tubes, rods, shapes and wires.
