SUMMARY:Repair of damaged coke oven battery walls with new developed fused silica gunning material 
DESCRIPTION:Oven walls in coke batteries that are in production for a long time can be damaged due to various reasons. To ensure production continuity, it is important to select a low-cost, short-time requiring, and effective method. Gunning, ceramic welding, and hot repair methods are the methods that can be selected in the repair process. Methods such as ceramic welding and gunning can be selected as a solution to light damages, but the repair of deepest damages reaching to middle section of the oven can be done by the hot repair method. Between battery wall repair methods, the most effective solution is the process of removing the bricks and knitting from it which is called hot repair. In this article, the methods that can be selected in the repair process of the oven refractory structure in batteries that have been manufactured for more than fifty years have been reviewed. It has been described that the repair of light and severe damages occurring to these batteries is possible in a short time with the recently developed material (Fused Silica Gunning Material). With this material, the life of the ovens was extended to 6 months by casting (gunning) to the depths of four and six combustion chambers in heavily damaged ovens requiring hot repair, which is deepest repair in the world. In these ovens production is continued thanks to this application. The existing refractory structure of ERDEMIR coke batteries, which continued to be in production since 1964 and which is one of the oldest batteries in the world, and the formation process of the structural damages have been demonstrated.
