Japan’s JFE Steel has resumed operating the No.6 blast furnace at its East Japan Works (Chiba) on 13 January after revamping it, Kallanish learns from the company’s official release.
The maintenance began last September and cost JPY 43 billion ($334 million) in total. The inner volume of the BF remains unchanged at 5,153 cubic metres, securing a capacity of about 4.5 million tonnes/year of iron.
“The revamping has helped to stabilise furnace operation by adopting data-science technology to improve the accuracy of both the positioning of material charging and controlling furnace heat,” JFE says.
In addition, adjacent equipment has been updated to improve workability and extend the life of the furnace body.
After being built in 1977, the No.6 BF completed its last overhaul in May 1998. The BF is now in its third campaign.
