For this purpose, the company appointed OTTO JUNKER GmbH with the task of delivering and commissioning a triple system plant consisting of three 12-ton induction furnaces and a common DC converter with two IGBT inverters and a melting capacity of 8 MW. The new furnace technology allows for a flexible, energy-efficient production reducing emissions to a minimum – a central step in the context of the sustainability strategy of the Italian company.
The concept is characterized by a flexible load distribution: One furnace can be run at full power while the other two are simultaneously used for holding and sintering processes. Control is via a centralized PLC architecture in connection with the JUMI operator desks. The architecture reduces investment and maintenance costs because not every furnace requires its own converter while, at the same time, requiring less space. More than anything, however, it optimizes energy use and increases equipment availability.
The induction furnaces are complemented by three charging machines make General Kinematics, an automatic bridge crane make Bonfanti, an automatic ladle handling system make Progelta S.r.l. and a dust collection system make Dizeta Impianti S.r.l. Another central element of the decarbonization strategy is the new photovoltaic system with a capacity of 2.6 MW which, in the future, will directly support the energy-intensive melting with renewable energy. The intelligent system integration helps optimizing own power consumption.
