The rolling process is the core of the whole rolling process. It is the product that the user needs to complete the deformation process by rolling the blank. The rolling process plays a decisive role in product quality.  The quality of rolled products includes geometry, dimensional accuracy, internal structure, process mechanical properties, and surface finish. Therefore, the rolling process must formulate the corresponding rolling process technical procedures and process management system according to the requirements of product technical standards or technical requirements, product characteristics, production technology, equipment capacity, production costs, and labor conditions of workers. In order to ensure the rolling product quality and technical and economic indicators to achieve optimization.  The rolling process is generally composed of one (Group) or two (Group) roughing mills, medium rolling mills, and finishing mills. It has the functions of billet section compression, s

Rebar Rolling Mill Production Process First, the Production Process of Rebar Rolling Mill Rebar is a ribbed steel bar, also known as a ribbed steel bar, usually with two longitudinal ribs and horizontal ribs evenly distributed along the length. The shape of the horizontal ribs is spiral, herringbone, and crescent. Expressed in millimeters of the nominal diameter. The nominal diameter of the ribbed steel bars is equivalent to the nominal diameter of the light round bars with equal cross sections. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Ribbed steel bars are mainly subjected to tensile stress in concrete. Ribbed steel bars have a greater bonding capacity with concrete due to the role of ribs, and therefore can better withstand external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. Rebar is produced by
