As is generally known, extremely demanding ambient conditions are encountered in continuous casting machines in particular for rotating unions: The cooling water flowing through is of very poor quality, mostly not filtered and includes particles which have an abrasive effect inside the rotating union. Furthermore, dirt of the ambient air deposits on the plant parts and is easily carried into the plant by rotating parts. And finally, there are mechanical loads acting on the system of roller and rotating union, e.g. components are not aligned perfectly.

These factors limit the service life of each rotating union; thus being a wear part.

Another “ambient condition” is the customer’s aim to reduce costs, if possible. That means avoiding machine downtimes and keeping maintenance costs as low as possible.

As leading manufacturer of rotating unions, DEUBLIN commits to continuously improving these aspects, i.e. maximising the service life of a rotating union or, if repair or replacement is required, to reduce the cost for this.
