Tension Leveler for Galvanizing Line

Structure Advantage of Tension Leveler for Galvanizing Line

Structure Advantage Of Galvanizing Line Tension Leveler (Dry Type)

• The frame of the tension leveling steel is an assembly part, and each part is annealed separately to eliminate stress and ensure the frame is not deformed after long-term use. Meanwhile, it also provides convenience for later maintenance.

• The roll-changing device is safe and convenient. It is driven by hydraulic pressure. One or all of the roller cassettes can be replaced at one time

• The top roller system can be opened quickly to prevent the roller from being damaged. The bottom roller system is used for improving the flatness by adjusting the insertion amount of the lifter. The ball cage coupling is used to connect the driving motor, lifter and detection encoder to facilitate flexible adjustment and maintenance.

• Configuring with two sets bending units and two sets leveling units can effectively improve the plate shap, C bending and L bending, according to the incoming material condition and process requirements, the two sets of bending units can also be used for one use and one standby.

• The main body of the tension leveler machine has taken effective waterproof, anti-rust measures, good sprinkler and backwater system, which can ensure long-term reliable and stable operation of equipment.

What's The Function of Tension Leveler In Galvanizing Line

The tension leveler machine is usually installed after skin pass mill in the continuous galvanizing unit. After the annealing galvanizing and skin pass process, the strip defect can be removed by the tension leveler machine to obtain good product quality.

Specifically:

1. Get good surface quality.  Under the action of leveling, bending, and straightening of tension leveler machine, strip defects such as strip wave, side wave, wavy, buckling and camber can be effectively eliminated, the flatness of the strip is significantly improved.

2. Eliminate yield platform and improve the reprocessing performance of sheet.  After the strip is annealed and galvanized, the yield platform will appear on the material strain curve. Under the influence of the yield platform, the finished sheet will have poor stamping forming performance and easy to produce wrinkles during the subsequent processing of customers, which will seriously affect the product quality.  Therefore, the cold rolled annealed sheet must eliminate the material yield platform, but the excessive deformation will cause new processing hardening for the sheet, the plasticity of the material will decline, the yield stress will rise again, to maximum elimination of yield platform used by the elongation.  The yield platform can also be eliminated by skin pass mill, but in the process, the strip surface will only be deformed. After the elimination of the yield platform, a faster aging recovery will occur, so the elimination is temporary.  The tension leveller can make the whole section of the strip deformed, and the deformation is in the vertical direction, transverse and longitudinal three degrees, the strip is not easy to produce aging recovery.

3. Eliminate the anisotropic of sheet, cold rolled low carbon steel in deep drawing process, the yield limit of material in transverse and longitudinal often showed obvious anisotropy, make the punched part uneven thickness in two directions, has lace skirt shape defects and not easy for deep forming. Through the proper process of tension leveler machine, sheet yield limit anisotropy is obviously improved,  The deep punching performance of sheet is improved effectively.
