“…The presence of cooling water above a smelting furnace has been a risk many furnace operators had to live with, and still has to live with. Examples of explosions due to water coming into contact with molten metal, matte, or slag are unfortunately numerous [10]. Cooling water is typically used to cool the electrode components, and in some industries the furnace roof, all equipment located directly above the furnace bath.…”

Tenova Pyromet designed, supplied, and commissioned a 12 MVA circular electric furnace for Sibanye-Stillwater (previously Lonmin) in South Africa. The furnace has been operating successfully since its commissioning in 2012. The paper provides an overview of the furnace performance and campaign life history, and explores the innovative design concepts and improvements implemented. Of particular interest is the use of a novel sidewall lining design that utilizes indirect cooling to remove excess heat from the matte/slag tidal zone without the need to use water-cooled copper. Furthermore, the performance of Tenova's Söderberg electrode column designed for base metal applications, limiting water use above the furnace, is discussed. In addition, the joint development and performance of an uncooled cast iron matte taphole faceplate is presented. Potential future design innovations to further improve smelter operating safety are discussed.
