Edwards installed its new-generation steel degassing system at Shyam Forgings in New Delhi, India. It is being used to perform vacuum oxygen decarburizing (VOD) in a production environment and offers potential energy cost savings of 90% over traditional steam ejector systems. The single steel degassing module runs the vacuum degassing and VOD processes to produce large degassed and decarburized castings up to 30 tons for Shyam Forging’s customers. The customers use the castings to produce large machinery components for power-generation markets across Asia.
Both ultra-low carbon steels and low-carbon stainless steels are processed through the VOD system in up to 13-ton melts for subsequent casting and machining at customer’s facilities. The order was worth more than $350,000, and the system is believed to be the first of its kind in India.
