The revamping process began last September and was carried out at cost of about JPY 43 billion (USD 334 million). Furnace volume remains unchanged at 5,153 cubic meters.The furnace is now in its third campaign or operating cycle, following previous campaigns that began in June 1977 and May 1998.The revamping has helped to stabilize furnace operation by adopting data-science technology to improve the accuracy of both the positioning of material charging and controlling furnace heat. In addition, adjacent equipment has been updated to improve workability and extend the life of the furnace body.
