Rolling technology for cold forming

DEM Costruzioni Speciali is strongly orientated towards innovation and the development of special applications for the ferrous and non-ferrous industry. The company has a long record of projects with outstanding demands in terms of technical performance and precise order execution, some of which are detailed below. In 2010 DEM designed and started up an automatic compact coiler with extra capacity up to 5-ton coils. The challenge consisted in having a perfect layer oscillated wound coil up to 1,600mm OD and large size with 5-ton capacity. Also in 2010, the company supplied one of the major Eastern European metallurgical groups of companies with worldwide operations. The project included delivery of a complete state-of-the-art profile wire rolling line to produce shapes with tight dimensional tolerances at high speed, yet with very short, industrial start-up. In 2009 DEM supplied a leading European company in the stainless steel and alloyed steel profile sector. The challenge consisted of designing and supplying a complete state-of-the-art profile wire rolling line to produce shapes in stainless steel with tight tolerances, at a high speed of 8m/sec. A year earlier, DEM supplied a European company in the stainless steel and alloyed steel wire sector. Conversion of a drawing line from die to micro-rolling concept resulted in higher speed, less maintenance and cut of intermediate treatments, and therefore increased uptime. The challenge consisted in processing wires in stainless steel materials and special alloys using rolling technology, and making rolls fit to withstand the heavy load generated by such ‘hard materials’.
