Two new systems from ATE

Applicazioni TermoElettroniche has been designing and manufacturing induction-heating equipment, including process automation, control and supervisor systems, since 1987. The company has recently developed two induction-heating systems – IMW (independent control wire) and CMW (common control wire) – for treating wires in parallel. Through the use of the most advanced technologies in the field of power electronics, these systems represent a sophisticated and efficient solution for the simultaneous heating of multiple wires with the same or even with different diameters. The main characteristics of the two systems are: IMW system – the possibility of heating multiple wires of different diameter separately, wire by wire, with the same or different temperatures and speeds (upon request). CMW system – the possibility of heating wires of the same diameter to the same temperature or wires of slightly different diameter to almost the same temperature, taking account of a suitable “Velocity x Diameter” relation (DV). Compared to other types of furnaces, such as resistance, gas, fluid bed or lead bath heaters, the IMW and CMW multi-wire induction heating systems have the advantages of no environmental pollution, being more compact, a higher efficiency and with an optional closed loop process control. Jörg Wadehn has been appointed technical director of Joachim Uhing GmbH & Co KG as successor to Burkhard W Bohn who retired in December 2012. Chartered engineer Jörg Wadehn (mechanical engineering) has worked for Uhing since November 2012 and has to his credit a wide range of technological expertise in executive positions in international companies including AVL Zöllner, Kiel, the world’s largest private manufacturer of engine dynamometers, and Vestas Wind Systems A/S. Mr Wadehn convinced with his

of around 720°C), stress relieving (max temperature of around 400°C), diffusion/brass coating of wires for steel cord (max temperature 550-600°C), preheating for galvanising (around 500°C), preheating for painting or coating (max 200-250°C), and preheating before an existing gas furnace in the case of increased productivity of the system. The IMW/IMS and CMW/CMS systems are completely modular and can heat a variable number of wires, and the configuration can be defined according to the needs of the customer. Given the flexibility of the system, any unit can be custom-designed to meet the application requirements. Applicazioni TermoElettroniche – Italy Website : www.ate.it

Besides wires, the systems are also able to treat metal strips or bands. In these cases the systems are identified with the codes IMS or CMS, instead of IMW or CMW. In addition to ferrous materials, the systems can heat aluminium, copper and brass, etc with efficiency values proportional to the type of material. The compactness of the heating unit allows them to be installed easily in limited spaces and, above all, in existing lines in which overall dimensions are binding. The frequency converter, the heat exchanger and the control panel can be positioned remotely in available spaces, even at a certain distance from the heating unit. The IMW and CMW multi-wire induction heating systems can be used in various industrial processes, including annealing (max temperature technical versatility, his expertise in filing patents, and the executive positions held so far. In his new field of responsibility, Jörg Wadehn will continue developing the tried and tested Uhing products for future applications, promote the development of innovations and further optimise the production processes. “I have a great number of visions to be translated into interesting products,” said Mr Wadehn.
