Siemens VAI Metals Technologies has received an order from JSC Electrometallurgical plant Dneprospezstal to supply a new electric arc furnace, complete with water treatment plant for its no 3 steel works. This modernization project will increase the steel works’ production capacity to 540,000tns of liquid steel per year. Siemens will supply an electric arc furnace with a tapping weight of 60tns and a tap-to-tap time of 48 minutes. The electric arc furnace will be powered from a 60MVA furnace transformer. The scope of supply also covers the furnace cooling water treatment plant. The cooling system is to be designed as a closed circuit in order to save water. Some 1200cum of water will circulate per hour to cool the electric arc furnace, transformer, hydraulic systems and waste gas pipes. On account of the relatively high temperature in the water circuit, appropriate chemicals will have to be added to prevent calcification and corrosion. Suspended solids will also be filtered out. The value of this order lies in the low double-digit million euro range. The modernized steel works is scheduled to come into operation in first quarter of 2012.
