inquiry The electric arc furnace operating cycle is called the tap-to-tap cycle. The EAF has developed as an efficient melting apparatus, with designs focusing on increased capacity. In modern EAF operations, especially those operating with a 'hot heel' of molten steel and slag retained from the prior heat, oxygen is often blown into the bath.
inquiry The electric arc furnace is stronger when it comes to dephosphorization than the induction furnace is. With the induction furnace, the slag is cold and the temperature of the slag is maintained by molten steel. With the arc furnace, the slag is hot and the furnace itself keeps it hot.
inquiry This map of production sites in Europe shows how widely steelmaking is distributed across the EU. Steel is made all over the EU, primarily using the Blast Furnace - Basic Oxygen Furnace (BF-BOF) 'primary' steelmaking route and via the 'secondary' Electric Arc Furnace (EAF) route.
