siemens-vai.com SIROLL Stepless Reform Tub System Innovative performance Your challenge: You want to form a wide variety of coil products with a conventional reform tub that satisfies your end customer. But the conventional reform arrangement, with its fixed iris and single coil plate, is not easily reconfigured to suit the unique needs of different product sizes and grades. Each installation is built to accommodate the largest billet size and tonnage rate the mill wishes to roll. The ability to adjust coil formation height is very limited, and therefore it is often challenging to maximize the benefit of the Siemens VAI Metals Technologies’ patented ring distributor, or to minimize the height from which the coil is dropped from the iris fingers onto the coil plate. The performance of the reform area depends on a multitude of factors, including finished product size, steel grade, and coil temperature. The inability to fully control the coil formation in the tub can result in taller, less dense coils that are harder to compact, ship and pay off for the downstream user. Our solution: Reliable and consistent formation of the highest possible quality coils – the SIROLL Stepless Reform Tub System has a patent-pending design to meet the needs of the modern mill in an increasingly competitive market. This revolutionary system is the first of its kind in the world to offer a seamless coil handoff through the use of dual interlocking coil plates mounted on independently driven carriages. These coil plates overlap to ensure a gentle, drop-free transition of the coil, preserving its shape during handling. The use of a moveable upper coil plate instead of a fixed iris also allows the mill to take full advantage of the ring distributor technology and form the entire coil at the optimum height inside the tub, regardless of the billet size, product diameter or grade. This can lead to costly mill downtime, higher scrap rates, and increased equipment maintenance costs. Efforts put into optimizing the ring pattern from the laying head to ensure coil quality can be made less effective by the ring drop depth of conventional reform tubs. Dual interlocking coil plate interface enables seamless coil transfer Answers for Industry.
