Scrap metal is delivered to a scrap bay, located next to the melt shop. Scrap generally comes in two main grades: shred (whitegoods, cars and other objects made of similar light-gauge steel) and heavy melt (large slabs and beams), along with some direct reduced iron (DRI) or pig iron for chemical balance. Some furnaces melt almost 100% DRI. Websome grades are processed at the tank degasser prior to casting. The electric arc furnace (EAF) stream uses a twin shell EAF, where the tapped heats are refined at LMF 2 and cast at 2CC. Several different grades are produced between the two streams, which include: ultra low carbon, low carbon, medium carbon, high carbon, HSLA, and dual phase ... WebThey have a twin Shell DC EAF operation. In December of 2001, PTI installed two JetBOxTM systems in one shell while the other remained unchanged. This allowed for a true comparison of the different chemical energy systems. The first heat produced with the PTI JetBOxTM was completed on Monday December 10th 2001. craft colleges uk
