The brick of coke-oven chamber walls is subjected to thermal and mechanical impact due to changes in temperature during coal carbonization and the lateral pressure applied at the time of coke pushing, and brick deterioration gradually progresses. Nippon Steel formerly repaired oven chamber wall brick by hot relaying at the Hirohata No. 2 Coke-Oven Battery and the Kamaishi No. 1 Coke-Oven Battery. In both cases the brick was relaid from the chamber end part (oven door). Therefore, if damage occurs in the middle part of the chamber, a large extent of brick relaying is necessary. The Hirohata No. 3 Coke-Oven Battery has recently been repaired by the boring method, in which only the brick of the middle part of coking chambers was hot-related. This report outlines the repair method newly adopted at that time.
