High Precision 20 High Cold Rolling Mill For AHSS SUS Steel (750)

20-high cold rolling mill for production of the stainless steel precision strip as well as high-strength carbon steel strip, copper, copper alloys, and special materials in perfect quality.

20Hi cold rolling mill undoubtedly is the optimum solution of thickness reducing for hard deformation alloy strips such as stainless steel strip.

The 750mm 20Hi mill 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:

  1. the mill stand is a whole structure of strong rigidity(the design rigidity coefficient 440-490T/mm), good for controlling metal plate thickness precision.
  2. the roller convex adjusting is more flexible and convenient, for the outer backup rollers are backup bearing type.
  3. the rolling line height can be flexibly adjusted by F,G rollers.
  4. axial transfer of middle rollers help plate edge shape control.
  5. cooling oil is supplied to lubricate rollers via guide plates in good lubrication performance.
  6. easy operation and maintenance and safe running.
  7. 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.
