Following a two-year construction period, LTV Steel Company commissioned a new six-meter coke oven battery and ancillary facilities in December 1981 at the S. Chicago Works. The battery is a 60-oven Didier grouped flue underjet design capable of firing coke oven gas and blast furnace gas. In late 1990, coke side refractory damage in the form of severe spalls and holes in the walls were observed. Numerous repair techniques--welding, guniting, panel patching, end flue repairs using zero expansion brick--were employed as interim measures until a comprehensive repair plan could be implemented. A repair plan (primarily for coke side flues) was developed which envisioned end flue repairs on six walls per year beginning in late 1991, early 1992 depending on refractory delivery. However, in late 1992 it became apparent that the coke side deterioration was occurring faster than expected and that extensive pusher side deterioration was also occurring. Because of these developments, another battery inspection was performed. On the basis of this inspection, it was determined that a major rehabilitation would be required to assure long-term, environmentally acceptable operation of the battery.
