The premature failure of copper staves in the lower stack and bosh is frequently the reason for an interim blast furnace repair at great cost to the blast furnace owner. Protective accretions may form on the stave hot face, but if these accretions are lost, the staves are exposed to abrasion from the descending burden materials that increases copper wear and results in cooling circuit failures. Such failures dramatically reduce stave life and lead to an early blast furnace repair/reline.
New research and technology developments addressing premature stave wear will be presented, complete with results obtained. These developments include a novel stave wear measurement and monitoring technique, as well as significant technology advancements in cooling remediation for extending campaign life.
