Electric Arc Furnace equipped by SiemensJSC Dneprospezstal is the Ukraine's leading manufacturer of special steels. Its product portfolio includes stainless and instrument steels, high-speed and roller bearing steels, alloyed structural and high-temperature resistant nickel-based steels. Dneprospezstal decided to modernize steel works no. 3 extensively in order to both increase the production capacity and reduce the per ton production cost.
Siemens will supply an electric arc furnace with a tapping weight of 60 tons and a tap-to-tap time of 48 minutes. The electric arc furnace will be powered from a 60 MVA furnace transformer. This new furnace will require less electrical energy per ton of steel produced than existing plants. The consumption of electrodes and other consumables will also be considerably less.
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 1,200 cubic meters 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.
