Kobe Steel shut down the operation of the ironmaking and steelmaking process at Kobe Works in October 2017, and in November 2017, this upstream process was consolidated at Kakogawa Works. Prior to this, by January 2017, the Steelmaking Department of Kakogawa Works had established a special-steel production system for wire rods by installing No.3 secondary refining equipment (2LF, 4RH) and a No.6 continuous caster. A challenge in designing the new process was to produce small lots of special steel with high productivity, high yield and high quality at Kakogawa Works, which has a large heat size. In order to solve this problem, cutting edge technologies were introduced in the upstream equipment. This has enabled small-lot production and quality improvement while continuing stable production under the full production system after the consolidation of the upstream process. This paper reports the features of newly installed equipment, the concept of quality design, and the operational status.
