Finishing mill for galvanizing lines

On the basis of digesting and absorbing foreign advanced technology, combined with the actual situation and years of engineering application experience in China, we have developed medium and high-end 1800mm, 1680, 1550mm, 1450mm, 1150mm and other width finishing units, which have been widely used at home and abroad.

Uses of Glimpse finishing mill for galvanizing lines:

Finishing machine is one of the key equipment in hot dip galvanizing production line, its main role is:

1) Obtain the required surface roughness of galvanized sheet and improve the production quality of the subsequent color coating process.

2) Improve the flatness of galvanized sheet.

3) Improve the mechanical properties of galvanized sheet, reduce or eliminate the phenomenon of slip line; Reduce or eliminate yield plateau phenomenon.

Features of Glimpse finishing mill for galvanizing lines:

1 Complete control functions of the unit: constant rolling pressure control (AFC), constant elongation control (AEC), roll gap position control (APC), constant tension automatic control (ATC) and other functions.

2. High automation level of the unit: automatic lifting/pressing function of over-weld, continuous calibration function, continuous roll change function, liquid compression function, etc.

3 The latest development of soft pressing function: Yang Wangli's new soft pressing technology of over-weld is at the leading level at home and abroad. The technology ensures that when the rolling force is not more than 2000kN, the weld passes directly, and the finishing machine does not reduce pressure and does not lift the roll; When the rolling force is greater than 2000KN, the finishing force is reduced to 200 tons, the weld passes directly, and the set rolling force is immediately restored after passing. The whole process does not need to lift the roller, and ensure that the roller surface is not damaged. The control can be divided into manual and automatic two modes; And can be switched at will.

4 The equipment level of the unit is high: the transmission system adopts full digital frequency conversion control, Siemens speed control device, basic automation adopts Siemens or ABB PLC, the configuration of touch screen and other modern control means, and the bending roll system adopts servo control.

5. Complete man-machine interface of the unit: specially developed data acquisition, display and storage system.

6. Plate shape control of the unit: positive and negative bending of the work roll

7. Constant elongation closed-loop control can be realized automatically

8. Equipped with high pressure water flushing slag system and anti-wrinkle roller, anti-jump roller.

9. Unit auxiliary system: medium pressure hydraulic station, high pressure servo hydraulic station, etc.
