Z-High® Mills - Process Line
Efficiency Redefined
Sendzimir introduced the Process Line Z-High® Mill design as a mill that could function in line with an annealing and pickling line for stainless steel at the beginning of the process line. Our first installation was at Nyby-Bruk in Sweden as a single stand without strip cleaning before the mill. Surprisingly, strip quality out of the pickle line was quite saleable! Since then, there have been numerous and far more sophisticated installations, including a high-reduction, stand-alone, single-pass Z-High®.
Advantages of Process Line Z-High® Mills
Uniquely Designed
The Process Line Z-High® Mill is the only mill capable of reducing and finishing hot-rolled stainless material directly to thin gauges in an inline process. Sendzimir’s Process Line Z-High® Mill work roll is large enough to take a significant draft reduction (H1-H2) on heavier gauges (8 – 10 mm) without skidding while at the same time having a sufficiently small diameter work roll to get down to thinner gauges (1+ mm). Reductions in stainless steel of up to 35% per stand have been documented in our Process Line Z-High® Mills. There is no other mill capable of this!
Continuous Production
The lightweight, chockless work roll can be exchanged in under a minute with a strip in the mill, ensuring virtually nonstop performance in a continuous production situation with a short-time strip accumulator upstream. Minimized production downtime means greater production yields for you; this is why Sendzimir has prioritized the innovative design of mills that create solutions for our customers.
Tandem Mill Construction
The Process Line Z-High® can be operated as a single stand but has also been supplied numerous times in tandem mill installations. These installations have been double-, triple-, or even four-stand tandem mills with a Z-High® in each stand.
Solid Mechanical Solution
Unlike other designs, the Sendzimir Z-High® has a solid mechanical connection throughout. The front and rear intermediate chocks are mechanically connected to each other. Moreover, the entire cluster arrangement is mechanically aligned and cannot fall out of alignment at any time.
No other mill builders have our experience in designing inline Z-High® Mills.
