In rolling mills of the steel industry, for example metal sheets, tubes and rails are manufactured from base products that are available in the form of bars or slabs. The blazing hot, extremely load-intensive rolled material must be stopped quickly, precisely and reliably in specific positions on the roller conveyors – a complex application situation which is perfect for the proven RINGFEDER® friction springs and industrial buffers. Since, due to the huge drive power of the roller conveyor drives as well as the enormous masses of the rolled material, top-quality, resistant pre-buffers with a correspondingly high energy absorption capacity are required. Industrial buffers and friction springs by RINGFEDER®, tailor-made to suit the respective application, are provided with tremendous damping performances at an extremely low weight and volume, are designed requiring zero maintenance, and ensure maximum operational reliability even under the extreme conditions that are prevailing.
