Jan 14, 1992 · Three-roll wipers embodying metallic wiper rollers have been used for over 10 years on some United States and many European Sendzimir mills (Z-mills) for rolling stainless steels. Their advantages relative to bar wipers (i.e., rubber hose type) are that both lost time due to frequent changing of wiper hoses and strip marking caused by chips which become embedded in the hoses are eliminated.

2.2.2 Friction Angles Between Rolls of the Roll System. The acting forces and the friction angles between rolls of the roll sys-tem of Sendzimir mill are shown in Fig. 2. According to Ref. 10, the friction angles and the acting forces between rolls are related to the structure of the roll system and the rolling force, which can be obtained from P
A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
