Rolls and rings are elementary mechanical components of rolling mills and the quality of the rolled product is mainly dependent on their quality. Roll failures may occur due to defective rolls, improper grade or hardness specification, unfavorable rolling conditions or a combination of all of the above.
Failure of rolls gives rise to critical problems such as likely damage to the equipment, downtime and replacement costs, partial or total loss of the production batch and missed deadlines, resulting in an overall decline in efficiency, reduced productivity and monetary loss. Therefore, it is essential to determine the root-cause of failure and identify preventative measures to be taken in order to prevent recurrence and improve overall mill performance.
Investigating the main reasons for failure as an impartial third party, Vulcan Metal aims to give helpful guidance with preliminary failure report, outlining the findings and providing context.
