Copper Stave Bending: Challenges, Management and Solutions (Room 404)

Copper staves have now been used in blast furnaces for 40 years, and Primetals Technologies has had great success with this technology — in terms of the stave designs, the profiling of the blast furnace, and the operational strategies that can be used to support a 20-year campaign. However, a number of non-Primetals furnaces have suffered from challenges when implementing copper staves. This paper will reference some of the problems in bending and wear that customers have encountered, along with the solutions Primetals currently offers.
