Abstract Numerical models in 2D and 3D are used to study induced currents the lining steel shell of large three-phase submerged arc furnaces. The alternating supplied through electrodes cause a significant amount power furnace shell. flow three loops with an accumulation current near top between electrodes. net result is thermal loss heat dissipated at surface. Furthermore, such may potentially...

Low energy efficiency of foundry class electric arc steelmaking furnaces (EAF) mainly is caused by heat loss massive lining during forced downtime. A low-power transformer doesn’t allow, in the conditions classical technology, practice traditional water-cooled elements order to replace partially lining, what determines increased refractory consumption. The aim and savings. On basis numerical mo...

An explicit equation leading to a method for improving furnace efficiency is presented. This equation is dimensionless and can be applied to furnaces of any size and fuel type for the purposes of comparison. The implications for current furnace design are discussed. Currently the technique most commonly used to reduce energy consumption in galvanizing furnaces is to increase burner turndown. Th...

Abstract With the development of iron and steel smelting technology, application proportion DC electric arc furnaces will gradually increase in future. In this paper, Simulink model is built with reference to 130-ton furnace produced by ABB ZHONG Shan Transformer Company Limited. model, power performances large-capacity are explored adjusting trigger angle, side resistance, reactor values. From...
