SUMMARY:Operational feedback of blast furnace anti-wear copper staves 
DESCRIPTION:In a blast furnace, copper staves are often used to protect the shell in the highest heat zones. These staves are in turn protected from the abrasive burden material by freezing semi-molten material onto the stave face, forming a skull and preventing wear. The stability of this skull is therefore essential to achieving a long stave life which consequently allows a longer and more stable blast furnace campaign. Primetals Technologies have developed a solution which traps burden material at the front of the stave whilst still allowing liquids through to the copper face – the result is a more stable skull and improved overall process stability.
This paper describes the equipment operated at SSAB Raahe since August 2019 and compares performance against the traditional design of stave. This paper describes the new stave design and its technical and commercial benefits over other designs, supported by operational data.
