Laminador en frío en tándem de cinco cajas

1) Big reduction rate: By only one rolling process, the mill can roll steel strip from 3mm to 0.3mm which meets the requirement of most of zinc galvanizing basic plates.

2) Full continuous: The mill will carry out completely continuous production from payoff reel to tension reel, which to be equipped with automatic welding machine, entry loop, exit flying shear and double tension reel  

3) Alta precisión: In order to warrant gauge precision and good flatness, five stands of the mill will be equipped with HAGC.

4) High benefit: Its cost of producing one ton of strip will decrease largely, because of increasing in yields and decreasing in personnel costs.

1. Full digital DC speed control in production line, closed loop control of tension and automatic control of speed.

2. Hydraulic automatic gauge control of five stands: including forward AGC, feedback AGC, monitoring AGC and mass flow AGC.

3. Positive/negative bending roll of working rolls, positive bending rolling of intermediate rolls and shift of intermediate rolls and rolls segmented cooling control.

4.  Matured basic automation and process automation control by PLC.

5.  Using double payoff reel, flashing welding machine, and spiral loop.

6.  Using double tension reel for winding strip.  

7.  Equipped with the system of collection, display, storage and input/output of data, including fault diagnosis and alarm system etc.

8.  Function of automatically decreasing speed and tension during passing welding seam.

9.  Quick working roll change without stripbreaking.

10.  Oil-air lubrication for total roll bearings.
