The main control requirement of the stretch leveller production line is to control the velocity difference between 2 # S roll and 3 # S roll, so that the elongation of the sheet can be set and the physical characteristics of the sheet can be changed. Therefore, it is necessary to select the appropriate devices that can meet the control requirements to constitute t…

Application Hengzhong technology guarantees a constant, high quality level with improved strip geometry (flatness, camber) that is unequalled in terms of efficiency and output using other methods. Tension leveling equipment can be used either as independent, single-purpose lines or as integrated parts of other processing lines. The most common fields of applicatio…

Tension Leveling is the process of pulling the strip beyond its yield point to permanently change the shape of the strip and make it flat. If you have an edge wave, the concept is to stretch the shorter fibers in the center of the strip so that they will match up in length with the longer fibers from the edge wave. Conversely, if you have a full center, you are at…
