This paper will discuss implementation of Z-BOP technology at Iscor's New Castle plant. The implementation program and operating results of Z-BOP-100 technology will be covered. The unique experience of the BOF shop operation without hot metal supply from the blast furnaces will also be described. This experience was a result of proprietary Z-BOP technology implementation at Iscor during its sole blast furnace reline. The Z-BOP is a family of technologies operating with scrap ratios in the charge from 30 to 100%. These technologies can be used in conventional top-blown BOF with virtually no equipment modifications. The principal additional energy source is lump coal, fed through existing BOF bin systems. Different modification of Z-BOP, originally used on the industrial scale at the West Siberian Steel Works, Russia, were utilized at several BOF facilities worldwide. Performance of the process and its main characteristics are discussed.
