Abstract

Following some premature damage to staves on the blast furnace number 2 at Ternium Siderar San Nicolás works an investigation of the cause of the problem was carried out. This analysis included for discussions with a number of blast furnace operators around the world. Ternium operational experience in dealing with worn staves proved to be valuable in terms of follow up, damage correction and prevention of damage experienced. This experience was also important in designing the new staves. These concepts are discussed in the paper. The output of the analysis was a decision to replace all rows of copper staves on the Ternium blast furnace. The replacement project was scheduled to be carried out in 2012 during a stoppage of the blast furnace. This paper will review the issues with the original stave performance related to the operation of the blast furnace and the design of the new staves. The paper will also describe the shutdown associated with the stave repair and techniques used to remove and replace the staves. When presented, the paper will discuss the latest performance of the staves on the blast furnace.
