Abstract
The objective is to discuss the performance of the blast furnace after a repair performed in 2005 of the Upper hearth layer, Tuyere zone, Bosh and Belly. In May 2012 the furnace reached the seven year target of the repair for the Belly of the furnace. The article will cover the following items: design of the repair; start up and ramping up the production; casting practices; way of operating, using both coke and charcoal as fuel; devices and system for measuring the lining thickness over time; the continuation of the furnace campaign, campaign lifetime, the future.
