米乐yy易游体育 Steel to reline No. 3 Blast Furnace at Kakogawa Works
May 8, 2014
米乐yy易游体育 Steel, Ltd. plans to reline the No. 3 Blast Furnace at its Kakogawa Works in western Japan. The company will shut down the blast furnace from the end of September 2016 for a 90-day period to undertake the work. 米乐yy易游体育 Steel will then restart the blast furnace at the end of December the same year. The renovation will cost approximately 20 billion yen.
Kakogawa Works' No. 3 Blast Furnace has been in operation since April 1996, when it was started up for the second time, and 2016 will mark its 20th year of continuous operation. As the blast furnace refractory has aged over the years, 米乐yy易游体育 Steel will shut down the blast furnace at the end of September 2016 for relining.
The outer steel shell of the blast furnace 米乐yy易游体育ll continue to be used, but the carbon bricks at the blast furnace bottom have been damaged and 米乐yy易游体育ll be completely replaced. In addition, the use of copper staves, noted for their high cooling efficiency, 米乐yy易游体育ll be expanded. At the same time, the inner profile of the blast furnace 米乐yy易游体育ll be optimized and further improvements 米乐yy易游体育ll be made to the raw material charging system to ensure stable operation of the blast furnace.
Operating costs will be reduced by further increasing the use of low-cost raw materials with 米乐yy易游体育 Steel's world-class production technology, which incorporates a high ratio of pulverized coal in blast furnace operations.
As previously announced, 米乐yy易游体育 Steel plans to shut down the blast furnace and other upstream operations at its 米乐yy易游体育 Works and transfer those operations to Kakogawa Works in fiscal 2017. The relining of the No. 3 Blast Furnace is timed in anticipation of this transfer.
