Abstract:

If the heating wall of coke oven battery is first repaired and then heated up under hot state,the adjacent heating wall and the wall surface not repaired will be damaged more quickly.Regarding to this problem,the revamping-heating technology is adopted to repair the heating wall while heating up.The expansion joint of silica bricks can be determined according to the temperature.With this technology,the repair effect is satisfying.It is of great significance for coke oven maintenance under hot state.
