Danieli will supply the new Electric Arc Furnace (EAF) Melt Shop and Plate-/Steckel-Mill, as well as an electrical and automation package provided by Danieli Automation. Nucor will invest approximately $1.35 billion USD to build the mill, which will be capable of producing 1.2 million net (US) tons per year of steel plate products.
اقرأ أكثرInitially, the electric arc furnace will be used mostly for melting steel scrap, says Jarmo Lilja, Process Development Manager at the Raahe steel mill. The manufacture of hydrogen-reduced sponge iron is set to begin at a demonstration plant in 2026 and the location of the production facilities is still unknown.

اقرأ أكثرRerolling Mill Furnace a) Batch type A box type furnace is employed for batch type rerolling mill. The furnace is basically used for heating up scrap, small ingots and billets weighing 2 to 20 kg. for rerolling. The charging and discharging of the 'material'is done manually and the final product is in the form of rods, strips etc.
اقرأ أكثرElectric furnaces also are employed, exclusively, by mini-mills, small plants using scrap charges to produce reinforcing bars, merchant bars (e.g., angles and channels), and structural sections. The German-born British inventor Sir William Siemens first demonstrated the arc furnace in 1879 at the Paris Exposition by melting iron in crucibles .

اقرأ أكثرArc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc and the current in the furnace terminals passes through the charged material.. For steelmaking, direct current (DC) arc furnaces are used, with a single electrode in the roof and the current return through a conductive bottom lining or conductive pins in the base.
