History Sloss Industries Corporation has been a major producer of blast furnace coke, foundry coke, iron, and steel in the Birmingham area since 1882. Sloss began the production of coke on the present site in 1919-20. The captive production of blast furnace slag and coke naturally resulted in the production of slag wool fiber at the current site in 1947. The slag wool operation began with the operation of the number 1 and 2 cupolas and the associated fiberization lines. A 1200 ton per day iron blast furnace went into production at the Sloss site in 1957. This further enhanced the manufacture of slag wool fiber since all of the raw materials were now available on site. In 1962, three additional cupolas were built and placed in operation. Then, in 1975, two more cupolas were added bringing the total to seven. Improvements in the process and manufacture of slag wool fiber and the age of the original two cupolas resulted in number 1 and 2 units being dismantled in 1983. The Sloss Slag Wool Plant now operates five coke fired cupolas under one roof, the largest number of cupolas at one plant anywhere in the world.
