Advantages of rolls refurbishing with a help of sleeving:

• low production costs,
• sleeves can be made of higher quality steels,
• sleeves can be better heat treated,
• sleeved rolls operational characteristics are minimally the same.

Disadvantages of rolls refurbishing with a help of sleeving:

• tensile stress permanent presence in a sleeve,
• higher danger of a sleeve failure in case of a sleeved roll wrong production technology or running.

State of stress calculations for the required overlap determination
