Rolling mills in the metals industry
Rolling mills produce aluminium and steel sheet metal coils for use in many of the world’s biggest industries, including automotive and can-making. Metal producers have very high standards when it comes to the quality of the finished sheet metal.
Chatter marks on finished metal strip can result in coils being rejected by the customer. This will not only lead to financial loss for the metal producer, but also unnecessary energy use as a result of the further operating time required to meet production targets with satisfactory, chatter-free, finished coils.
Preventing excessive 3rd and 5th Octave resonant vibration in rolling mills allows rolled metal producers to meet their productivity, quality and sustainability targets.
How can Vibremo help?
We have extensive experience carrying out vibration inspections on cold and hot rolling mills in the UK, Europe, and further afield. Vibremo has the technical skills and knowledge to identify and solve your mill vibration problems.
• Chock bearing defects
• Chatter marks on the rolls
• Coupling misalignment
Among other things, excessive mill vibration can be caused by:
• Gearing issues
• Lubrication problems
Vibremo also offer regular ‘health-checks’ on rolling mills. These can be every 3 to 6 months and allow for any potential future vibration or chatter issues to be identified before they begin to cause quality issues on the finished steel or aluminium coils. We can also perform rolling mill fingerprinting.
Our analysis allows us to identify the best rolling speeds and to determine the vibration signatures of the back-up and work rolls as well as their chock sets.
The root-cause of chatter marks on output strip is often related to chatter marks on the roll caused by the grinding process. Vibremo offer a roll grinder inspection service to help with this issue.
