Edging rolls, as the name suggests, are rollers used in steel rolling mills to roll the edges of steel. Their structure typically consists of a roll body, roll neck, shaft end, and bearings. The roll body is the part that directly contacts the steel, and its material and shape directly affect the rolling effect and product quality. Depending on the application and material, edging rolls can be divided into several types, such as flat rolls, vertical rolls, and grooved rolls. Flat rolls are mainly used for plane rolling, while vertical rolls are specifically used for rolling the edges of steel, and grooved rolls are suitable for the rolling needs of specific cross-sections.
Working principle of edging rolls
During the operation of a steel rolling mill, edging rolls, through rotation and extrusion, plastically deform the passing steel. When the steel enters the rolling mill, it is first roughly rolled by the roughing mill to form the basic cross-sectional shape. Subsequently, it enters the finishing mill, where the edging rolls precisely roll the edges of the steel to achieve the required dimensions and shape. The roll gap adjustment, speed control, and rolling pressure of the edging rolls are all key factors affecting rolling quality. By precisely controlling these parameters, the dimensional accuracy, surface quality, and mechanical properties of the steel can be ensured. The production capacity and product quality of the steel rolling mill contribute to the sustainable development of the steel industry.
