Medium-frequency melting system for Vestas Castings Guldsmedshyttan AB, Sweden
For this Swedish foundry forming part of the Vestas group, one of the world's leading manufacturers of wind power plants, OTTO JUNKER will supply a complete turn-key medium-frequency melting plant this year for the production of large iron castings. The melting installation will comprise two 25-tonne furnaces. Its DUOMELT frequency converter system will have a rated output of 6,000 kW and operate at 180 Hz. Two vibrating chutes for charging the furnaces, a 20 deg. furnace back-tilting system and powerful exhaust hoods will ensure the safety and environmental compatibility of these large melting furnaces. The water re-cooling system will have separate circuits for the furnaces and the switchgear system and will rely on the use of water/water heat exchangers. A JOKS melting processor will control and monitor the entire installation.
At OTTO JUNKER, activities are progressing in line with the agreed objective of handing the system over to the operator, ready for production, on 11 June 2010.
By making this investment, Vestas aims at optimizing its melting technology at Guldsmedshyttan Works while improving environmental conditions as well as health and safety at work.
