Abstract

The technology known as Sequence Impulse Process (SIP) injects oxygen with high kinetic energy through the tuyeres on a regular basis. This method improves the local conditions within the raceway of the furnace and enhances its overall performance. In this paper, the principles and key components of this full-scale technology will be introduced, along with some impressive findings from operational results at the world's first blast furnace to use SIP technology, which is operated by thyssenkrupp Steel Europe AG at their Duisburg site in Germany. Previous reports have shown that the use of SIP technology results in a reduction of the total fuel rate and CO2 emissions, as well as enabling higher productivity and a stable use of increased PCI rates on the blast furnace. The current paper will focus on results from a period where low-quality raw materials were used and will provide new information about the performance of BF1 with SIP technology compared to the minimum fuel rate requirement and the performance of other blast furnaces at the same site during that period.
