The first cold rolling mill in Phu My, Vietnam, to produce cold-rolled strip for the construction, automobile and white goods industry is to take delivery of a Hicon/H2® bell annealer facility to anneal steel strip coils in straight hydrogen from Ebner-Industrieofenbau, Austria. The strip coils weigh up to 25 tonnes, and each workbase is loaded with a maximum net charge of up to 105 tonnes. Special attention is paid to the cleanliness of the strip surface and to optimum temperature distribution throughout the coil. As part of the annealing cycle, the strip coils are cooled to skin-pass temperature utilising the highly conductive hydrogen.
Ebner’s scope of supply consists of five gas-fired heating bells, 12 Hicon/H2® workbases with valve stands and inner covers, seven combined air/water cooling bells and a complete control center with state-of-the-art visualization system. The facility is an integral part of the complete mill equipment supplied by Danieli, Italy. Commissioning of the facility’s first stage is scheduled for the middle of 2004.
