Stainless steel production

Linear cage forming for stainless steel from Italy

and easier and faster maintenance. The Linear Cage Forming for square and rectangular tubes, developed and patented by Olimpia 80, can carry out the forming change operation in a very short time and without any replacement of rolls. The system is applied to any part of the production line: forming, welding, sizing or straightening. The line set up is, as a result, totally automatic. The square or rectangular shaping is directly carried out before the tube welding, with important advantages in terms of power and material cost reduction. Olimpia 80 has put into operation tube mills with this technology in Germany, Turkey, Italy and USA.

The tube forming system, developed and realised by Olimpia 80, makes use of the latest technologies which allow the user to vary the diameters of the tubes to be produced without any changing of the rolls. The compact system consists of 11 sequential stations, eight of which operate as breakdowns and three operating as finpasses. This combination allows a final and complete closure of the tube before the welding. The 86 independent axles, operated by computerised servomotors and an easy-to-use operating interface system, help to reach in a quick and simple way the optimal position for the correct tube forming. Strip feeding is assured by a system of independent pinch-rolls, which are installed on the first six stands. The main advantages of the system are adjustment flexibility; automatic change of tubeODand gauge; significant change over time savings; tool cost reduction for round tubes; labour cost reduction;

OLIMPIA 80 has specialised for over 40 years in engineering and manufacturing a wide range of tube mills for carbon steel, stainless steel, titanium and non- ferrous materials to produce round, square, rectangular and special profiles. The company can also supply turnkey systems, find custom-made solutions, offer suggestions to upgrade old systems, and provide a complete after- sales technical and personnel training service. The company can propose the innovative and patented technology named Linear Cage Forming, in two different solutions: for round tubes; and for square and rectangular tubes. The Linear Cage Forming system is the result of many years of experience and knowledge in the tube field. This method brings advantages in terms of flexibility, production capability and production cost reduction. The innovation consists in the possibility to produce any tube in any size, included into the mill range, without roll change and in few minutes with an extreme reduction in set up time.
