Abstract: A method provided with a lance for repairing the oven surface of a coke oven comprising the steps of providing a distance sensor at a leading end of the lance, quantitatively measuring the depth of a worn out portion by means of the distance sensor, and spraying repairing material to the worn out portion from a repairing nozzle based on the measured results to repare the worn out portion. In addition, a lance used in this repairing method has a multiple-stage configuration of a polygonal cross-section and is free to be extended and/or contracted, whereby it is possible to scan the oven wall surface linearly or planarly. If the leading end of the lance is designed to be moved in accordance with the basic operation patterns and/or movement patterns, a repairing range of complicated configuration can easily be repaired.
