A combined tension leveler with scale breaker is an integrated strip-processing machine used in metal manufacturing lines to improve the surface quality, flatness, and mechanical consistency of steel or other metal strips. It combines two important functions in one system: scale breaking and tension leveling. By merging these processes, the equipment helps simplify production flow, reduce line length, and improve overall efficiency.The scale breaker section is designed to remove or weaken the oxide scale that forms on the surface of hot-rolled strip during the heating and rolling process. This scale is usually hard, brittle, and strongly attached to the metal surface. If it is not properly treated before further processing, it can cause surface defects, interfere with coating, and reduce product quality. The scale breaker typically uses a set of work rolls that apply repeated bending and pressure to the strip. This mechanical action cracks the scale layer and prepares it for removal in later stages such as pickling or brushing. In some lines, the breaking action also helps reduce the risk of scale marks being pressed into the strip surface.The tension leveler section follows the scale breaker and is responsible for correcting shape defects in the strip. During rolling, coiling, uncoiling, and handling, strip material can develop waviness, edge waves, center buckle, crossbow, and residual stress. The tension leveler eliminates these problems by passing the strip through several alternating bending rolls while applying controlled tension at the entry and exit sides. This repeated bending and stretching produces a uniform elongation across the strip width, which helps stabilize the metal structure and improve flatness.When the two functions are combined in one machine, the strip can be processed more efficiently in a continuous line. The scale breaker prepares the surface, and the tension leveler improves dimensional quality and internal stress distribution. This combination is especially useful for hot-rolled strip, heavy-gauge material, and products that require high surface and flatness standards before downstream operations such as pickling, cold rolling, galvanizing, painting, or slitting.A combined tension leveler with scale breaker usually includes entry guides, pinch rolls, work roll assemblies, backup rolls, tension control devices, drive systems, hydraulic adjustment systems, and automatic control units. Modern systems may use digital monitoring to regulate roll gap, bending force, strip tension, and processing speed. This allows operators to handle different strip thicknesses, widths, and steel grades with high accuracy and repeatability.The main advantages of this equipment are improved surface preparation, better flatness, lower residual stress, reduced production steps, and higher line productivity. It also helps decrease downstream defects and improves the final appearance and performance of the product. For many strip processing operations, the combined tension leveler with scale breaker is an essential solution for achieving stable quality and efficient manufacturing.
