Ovako Tube and Ring Orders Induction Heating Equipment
SMS Elotherm has been awarded two orders for induction heating equipment by Ovako Tube and Ring AB of Hofors, Sweden. EloBar™ will be used at Ovako’s forging operations to heat steel bars at a production rate of up to 8,000 kg per hour. With an installed electrical power of 4,000 kW, bars of up to 130 mm (5 inch) diameter can be heated to 1220°C (2228°F). SMS Elotherm will supply the bar handling system, the induction heater with a hot shear and an industrial robot for the transfer between hot shear and press. The EloBar facility will be commissioned in mid-2013.
SMS Elotherm will also supply an EloTube™ induction system, which is part of Ovako’s modernization program. It will be placed in front of an existing Assel mill in a seamless tube plant. Hollow blooms coming directly from a rolling mill upstream will be reheated and equalized before entering the mill. The induction system consists of six coils powered by state-of-the-art converters with transistor technology (IGBT), totaling a rated power of 6,400 kW.
