Classification of Steel Rolling Mill
Steel Rolling Mill, the process of changing the shape of ingot and billet between rotating rolls, is called rolling. The purpose of steel rolling is the same as other pressure processing, on the one hand, in order to get the required shape, such as steel plate, strip, wire, and various types of steel; On the other hand, in order to improve the internal quality of steel, our common automobile plate, bridge steel, boiler steel, pipeline steel, rebar, steel, electrical silicon steel, galvanized sheet, tin plate, including the train wheel are processed through the steel rolling process.
Rolling method according to rolling temperature can be divided into hot rolling and cold rolling; According to the relative motion relationship between the rolled piece and the roll, it can be divided into longitudinal rolling, cross rolling and cross rolling. The characteristics of rolling products can be divided into general rolling and special rolling. Cycle rolling, spinning rolling, and bending forming are all special rolling methods. In addition, due to the variety of rolling products, different specifications, some products are produced after several rolling, so rolling production is usually divided into semi-finished product production and finished product production two categories.
