RollPAC

During a mill crash, rolls can be damaged and develop micro-cracking. This cracking could lead to an explosive shattering or fragmentation of the roll and unfortunately, serious injuries are the result. In order to avoid these circumstances, Acoustic Emission testing can be used in addition to current safety practices. Acoustic Emission (AE) is a technology that hears active micro-cracking in rolls. 

Once the cracking emissions stop, rolls are safe to move. If rolls are acoustically active, they can remain in a safe storage area until the activity stops. Steel and Aluminum companies have been using this technology for over 15 years
