Sendzimir 20Hi Reversible Cold Rolling Mill Line represent advanced technology of cold rolling mill, unique in making very thin hard metal strip (stainless steel, titanium alloy, etc.), reversible rolling at high speed 600m/min, Sendzimir mill model mostly is medium, economical and efficient, very high precision.

To make high precision high value non-ferrous steel strips or high quality hard steel strips, when normal 4high 6high rolling mill is not capable, We can provide option of multiple rollers cold rolling mills like 8High, 12High, 18High, 20High.

Competitive advantages of multiple rollers cold rolling mill:

1.More thickness reduction than normal rolling mill in each rolling process. For example, a 18 high rolling mill can reduce HR stainless steel strip from 2.0mm down to 0.3mm with no need of interim annealing.

2.Can give better quality of CR metal plates, better flatness.

3.Less power consumption for the same production.

4.In some applications, only multiple high rolling mill can achieve the required performance.

The high precision multiple rollers rolling mill require very high precision manufacture and more investment, so the rolling mill exist in high quality metal strip making.

20high cold rolling mill

20Hi cold rolling mill undoubtedly is the optimum solution of thickness reducing for hard deformation alloy strips such as stainless steel strip. The 650mm 20Himill proposal is made as per the marketing requirements of finished product and feasible machine configuration, which can guarantee producing all the required product sizes in stability at economical cost and thus good profit.

The technical characteristics of the 20Hi Mill:
a.the mill stand is a whole structure of strong rigidity(the design rigidity coefficient 440-490T/mm), good for controlling metal plate thickness precision.
b.stable rollers system: hundreds of 20Hi mills around the world don’t happen rollers unstable problem. Moreover, small work roller diameter can reduce plate to very thin degree.
c.the roller convex adjusting is more flexible and convenient, for the outer backup rollers are backup bearing type.
d.the rolling line height can be flexibly adjusted by F,G rollers.
e.axial transfer of middle rollers help plate edge shape control.
f.cooling oil is supplied to lubricate rollers via guide plates in good lubrication performance.
g.easy operation and maintenance and safe running.
