Coke oven chute cleaning problem

It can't be cleared with two sections of cleaning rod, and one-inch pipe can't be knocked through from the top of the stove. May I ask what good advice do you experts have? Please give me more advice.
The chute is inclined and the temperature of the combustion chamber is high. The top of the furnace is stabbed with a steel drill, which is difficult to control. If you do it quickly, you may damage the furnace body. ； If it's too slow, the steel drill may soften and it won't be effective. Before dealing with it, I think we should further confirm whether the reason for the inability to burn is that the chute is blocked, or whether the heating gas is blocked? (I don’t know whether it’s coke oven gas or blast furnace gas for heating) The chute is blocked, and I haven’t thought of a better way. The only way to try is to remove the sealing wall of the regenerator. The fire adjustment team must control the furnace temperature, lower the temperature of the horizontal row of the combustion chamber, and adjust the adjacent ones as well. At the same time, measure the temperature of the storage roof. After it reaches a temperature that can be manually operated, cut off the gas in the combustion chamber and only allow air to enter. (Haha~~These are all safety measures) After the safety measures are taken, it is time to remove the sealing wall and clear the blockage. Make an opening as needed, move quickly, and repair it after it is completed. If the checkered bricks are seriously clogged, you can take the opportunity to replace them. For reference only.
Thanks for the advice. Our factory uses coke oven gas. It was the chute that was blocked, not the brick gas duct used for heating gas. Today, we used the method of digging and repairing the furnace wall to clean the chute. It's going well. Now the 1-2 hole vertical fire channels can be heated normally. But this method is not good and will cause too much damage to the furnace wall. The purpose of this discussion is to find a better solution.
The coke oven in our factory also experienced chute blockage. What is blocked in your plant is the burner part. What should you do if it is in the middle? I think the clogged chute is caused by graphite buildup caused by leakage in the burner head. Our factory is blown by wind. It works great.
Have you ever thought about using a thick iron chain? You may have good results if you try it! The iron chain should be thick and heavy enough
