In recent years, MET has always been devoted to providing the professional and reliable tension leveling line and improving its working process and efficiency. The further development of tension leveling lines has made MET the leading role in the leveling of thin and thinnest metal strips.
The main equipment used in the tension leveling line is tension leveler. Its purpose of adopting the tension leveler is to make the bending part of the steel subject to considerable reverse bending or stretching, causing a certain degree of elastic-plastic deformation in the part. When there is no external force, the steel undergoes elastic recovery and then reaches a straight shape. By adding tension and bending during the straightening process, material parameters, such as yield strength, elongation and spring bending limit can be well adjusted and internal stresses also reduced. As a result, strip shape deviations such as waviness, the cross bow, the longitudinal bow and the camber are reduced to a minimum.
The process of tension leveling line can be simply divided into three procedures.
The first is sheet metal feeding, which means that put the sheet metal on the feeding port of the tension leveling machine, and send the sheet metal into the embossing area between the upper and lower rollers through the feeding mechanism. The motors of the two rollers drive the rollers to rotate.
The second is corrective stretching: As the sheet metal passes through the embossed area between the rollers, it is subjected to pressure and tension from the rollers. Under the action of these two forces, the metal sheet will undergo elastic deformation, and as the sheet passes through, the degree of deformation will gradually increase to achieve the effect of rectification and stretching. When the sheet reaches the discharge port of the machine, the sheet has been straightened and then stretch to desired size.
The final procedure is inspection and adjustment. After the metal plate passes through the tension leveler, it needs to be inspected carefully to ensure the effect of straightening stretching and processing accuracy.
