Title:

コークス炉炭化室の炉底際壁面の補修方法及び補修装置

Document Type and Number:

Japanese Patent JP4528361

Kind Code:

B2

Abstract:

A repair method for the wall surface of a coke oven chamber at the bottom edge thereof is a method for repairing a damaged part on the wall surface of the coke oven chamber close to the bottom thereof, and comprises an oven bottom profile measuring step for determining a oven bottom approximation curve which approximates the oven bottom by measuring the distance between an oven bottom profile measuring device and the oven bottom in the vertical direction while moving the oven bottom profile measuring device along the length of the oven in the coke oven chamber to thereby determine the irregular shape of the oven bottom, an oven wall profile measuring step for determining the irregular shape of the oven wall while moving an oven wall profile measuring device in parallel with the oven bottom approximation curve so that the shortest distance between the shell of the oven wall profile measuring device and the oven bottom approximation curve is at least a first predetermined distance, and a repair step for spraying a repair material from thermal spraying equipment to the damaged part while moving the thermal spraying equipment in parallel with the oven bottom approximation curve so that the shortest distance between the shell of the thermal spraying equipment and the oven bottom approximation curve is at least a second predetermined distance.
