Description

Electric arc furnace (EAF) transformers are required for many different furnace processes and applications. They are built for: o Steel furnaces, mainly long arc o Ladle furnaces o Ferroalloy furnaces and similar with short or submerged arc STS is a global supplier of transformers for high-current industrial processes like aluminum electrolysis or arc furnaces for steel and other metals. Furnace transformers for AC EAF operation have a large area of applications. From the very demanding and cyclic AC steel furnace operation, with frequent short circuit conditions in the furnace, to the submerged arc operation in furnaces. These transformers have to be adequately protected against harmonics and frequent overvoltages (HV and LV sides) generated by the operation of the process, and the very high mechanical and thermal stresses have to be contained by a rigid design. Design Requirements for AC Arc Transformers: Managing very high secondary currents - for steel up to 90 A.
