Rolling steel is a production process in which steel ingots or continuous casting slabs produced by steel mills are rolled into steel. The steel produced by rolling method can be roughly divided into profiles, wires, strips, steel pipes, special steels according to the shape of the section. . The method of rolling steel can be divided into hot rolling and cold rolling according to different rolling temperatures; according to the relative motion relationship between rolling and rolling, the rolling can be divided into vertical rolling and cross rolling; according to the forming characteristics of the rolled products, it can be divided into General rolling and special rolling. Spinning and bending are all special rolling. Rolling, like other processes, plastically deforms the metal to produce a product. The difference is that the rolling work is carried out between rotating rolls. The rolling mills are of two major categories, the main equipment of the rolling mill or the main train of the rolling mill, auxiliary machinery and auxiliary equipment. Equipment used to deform metal in rotating rolls is often referred to as the primary equipment. The line in which the host devices are arranged is called the main frame of the rolling mill. The main machine column consists of three parts: main motor, rolling mill and transmission machinery. Rolling mills are classified according to their use: roughing mills and blanking machines, section rolling mills (large, medium, small and wire), strip machines, steel tube mills and other special purpose mills. The mill and the section mill of the rolling mill are nominally the diameter of the rolls. The strip mill is nominally the length of the roll body. The tube mill is nominally the maximum outer diameter of the roll that can be rolled.
