Overview of Technology for Low Temperature Ductile Iron Castings in Wind Power Generator

From the aspects of the status quo and prospects of wind power industry,the casting process,shaping,composition design,melting,annealing,and so on,the requirements of standard,process and equipment and the notes etc.of low temperature ductile iron in wind power generator were expounded,and the importance of quality management was emphasized.Integrating the experiences from industrial-strength enterprises show that it is a key of getting stable high-quality castings to use a good rigid resin sand in molding and a smooth and greater flow in filling,to select safety riser and high quality raw materials and to strengthen the processes of nodulizing,inoculation and annealing.
