Abstract
Repairing a chamber coke oven by heat-insulating a repair space in the oven, dividing a brick wall in a portion to be repaired into a plurality of layers stacked one above another, dismantling and removing the brick wall in the repaired portion, and carrying refractory assemblies into the oven one by one, each of the refractory assemblies being manufactured outside the oven by combining a plurality of bricks together correspond in shape to each of the stacked layers in one-to-one relation, thereby building the brick wall in the repaired portion with the refractory assemblies. A damaged combustion chamber brick wall of the coke oven near an oven opening can be repaired with high efficiency.
