Scale-breaking tension leveller, also called scale breaker, is generally used for continuous pickling units. Scale breaker machine applies to bend stress to strip steel. The front and rear bridle roll applys tensile stress to the strip; Under the coordination of these two stresses, the strip can produce moderate elongation under the condition that the tensile stress is far below the yield limit of the material. On the one hand, this extension realized by scale breaker can improve the shape of the strip and eliminate the defects such as wave, buckling and camber, at the same time, the internal stress and yield platform are eliminated to improve the mechanical properties of the strip. On the other hand, due to the huge difference between the oxide layer on the surface of strip steel and the iron matrix in performance, under the action of bending and stretching, a large number of oxide layer will fall off, and the oxide layer still attached to the surface will also crack, so as to improve the efficiency of acid tank pickling descaling.

Rewinding/ recoiling lines will encounter the problem of strip skidding during the actual usage which can lead to production barriers like strip deviation, at the meantime, coil processing line can affect the security of production equipment. With the pressure roller, tension rolls for the rewinding unit can prevent the strip from slipping on the surface of the rolls and get initial tension. BOYA Rewinding Line Features The force increase of tension roller unit was achieved by wrapping effect of each tension roll. In the condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface. Automatic Sleeve Feeding arrangement system. Entry Flattener with Quick Opening Feature. Doctor blade to be provided for all entry/exit deflector rolls, bridle rolls, and turn rolls. The Coil car will have auto coil shuffling to move the coils up to saddle one. Full line canopy covers. The Belt Wrapper is designed in such a way that it will be suitable for under and recoiled. Tinplate and Carbon Steel. Trimming Speed: 720Mpm Leveling Speed: 600Mpm Rewinding Line Strengths The coil car will be lifted up to the collapsed mandrel So that we can easily unload small coils from the mandrel. Low pressure system to prevent damage when removing small coils. Improve the flatter efficiency. High precision and stable control system. Safety and reliable production process. Compact structure and easy maintenance, environmental protection. Rewinding Line Working Principle 01 The recoiling line running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force. 02 The slipping of any tension roll unit will cause scratches to the surface of the strip. In the rewinding line, the light damage can degrade product quality, while the heavy one will scrap the strip. So the slipping of the tension roll unit is extremely harmful to production. 03 At the same time, the slipping of any tension roll unit will have a direct effect on itself, which can make the roller surface smoother and smoother. The friction coefficient diminished rapidly, so we need to regrind the roll surface and the roll usage period will be shorted. In addition, the skidding of tension roller unit can cause motor output torque to fluctuate, impact the transfer decelerator, make gear failure and defect the decelerator. 04 In order to prevent slipping, rewinding line diameter is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of coil processing line strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface. 05 Although we cannot eliminate the slipping of tension roll through the way of improve the electrical control of tension roller unit, we can provide the reasonable and perfect electrical control method which can benefit to diminish the degree of slippage. Therefore, we can decrease the wear of tension roll, and it is helpful for us to find and correct the slipping.
