摘要：
A new method of knurling with hard-alloy rollers is proposed to strengthen rolling-mill rolls. The method makes it possible to restore the original service properties of the rolls and improve their durability while eliminating the shortcomings inherent in existing strengthening methods. Use of the method shortens the strengthening operation threefold and reduces material costs by 11 % compared to strengthening by heat treatment. A standard knurling unit has also been developed to allow practical application of the new method.
