A combined type tension leveler is a highly efficient flatness correction machine designed to improve the quality of metal strips, sheets, and coils during continuous processing. It integrates the functions of tension control and leveling correction in one compact system, making it an important piece of equipment in modern rolling, slitting, and finishing lines. By combining these two processes, the machine helps eliminate defects such as waviness, edge waves, center buckle, and residual stress, while maintaining stable strip movement and consistent product quality.The main working principle of a combined type tension leveler is based on applying controlled tension to the material while it passes through a series of precision rollers. The strip is first guided into the machine and stretched under a carefully regulated pulling force. At the same time, it is bent repeatedly through multiple leveling rolls. This combination of tensile force and plastic deformation helps redistribute internal stress within the material. As a result, the strip becomes flatter, more uniform, and less likely to deform after processing.This type of machine is especially valuable for materials that require strict dimensional accuracy and excellent surface quality. It is commonly used for carbon steel, stainless steel, aluminum, copper, and other non-ferrous metals. Depending on the application, the system can be adjusted to handle different thicknesses, widths, and material strengths. Modern combined type tension levelers are often equipped with automatic control systems that allow operators to precisely set parameters such as tension, roll gap, entry and exit speeds, and leveling intensity. These controls improve repeatability and reduce manual intervention.One of the key advantages of a combined type tension leveler is its ability to achieve superior flatness compared with simple leveling equipment. Because the material is processed under tension, the machine can correct even subtle shape problems that might remain after conventional leveling. It also helps reduce springback, improves coil set removal, and enhances the performance of downstream operations such as stamping, welding, coating, and cutting. In addition, the integrated design saves floor space and simplifies production flow, which is particularly beneficial in high-volume manufacturing environments.The structure of the machine usually includes an entry section, tension control system, leveling roll stand, drive units, exit section, and an advanced electrical control cabinet. Some models may also include hydraulic adjustment, servo drives, and online monitoring systems to support precise operation. Durable rollers and rigid frame construction are essential to ensure stability, accuracy, and long service life under continuous industrial use.In modern metal processing lines, a combined type tension leveler plays a crucial role in quality improvement and productivity enhancement. It helps manufacturers produce flatter, more reliable, and more valuable products while reducing scrap and rework. With its combination of tensioning and leveling functions, this equipment has become an indispensable solution for achieving high-performance strip and sheet processing.
