摘要： PROBLEM TO BE SOLVED: To provide a measuring method for the oven wall position of a carbonization chamber in order to evaluate the status of damage on oven wall refractories in a carbonization chamber of a coke oven, whereby the status of damage on the oven wall can be accurately checked without being influenced by the deviation of the locus of a range finder in the oven width direction in the carbonization chamber while measuring individual distances to the left and right oven wall not the oven width.
SOLUTION: In the method for measuring the position of an oven wall of a carbonization chamber, a rangefinder 1 is inserted through the oven mouth of the chamber and, while moving inside the chamber, measures the distance between itself and the oven wall. In the method, the distance Xa between an oven mouth ironwork 6a at the insertion side A and the rangefinder and the distance Xb between an oven mouth ironwork 6b at the outlet side B and the rangefinder are measured to determine the oven-width-direction positions of the rangefinder at the insertion side A and at the outlet side B. On the basis of the determination result, the oven-width-direction position (the locus 12 of the center 10 of the measuring device 2) of the rangefinder at each position in the chamber is determined. Thus, the oven wall position is calculated from the measurement results of the distance between the oven wall and the rangefinder.

摘要： PROBLEM TO BE SOLVED: To obtain a distortionless and clear image of the inner wall surface of a carbonization furnace by writing the one-dimensional images photographed by a moving camera into an image memory after synthesizing them into a two-dimensional image and displaying the data stored in the image memory on a screen. SOLUTION: In order to obtain a two-dimensional image by means of the one-dimensional cameras, an arm HSA where a photographing head SHD is attached is supported by a carriage placed outside a furnace and reciprocated in the (y) direction. The video signals of one-dimensional CCD cameras LC1 to LC6 are extracted synchronously with a (y) synchronizing signal. When the right and left vertical wall surfaces W1 and W2 are photographed, the cameras LC1 to LC5 are turned right and left. That is, these cameras are put on a turning mount AMT and this AMT is turned by a set angle by a turning drive motor AZM. Thus the cameras LC1 to LC5 are turned, so that each of visual field center lines these cameras forms a prescribed horizontal angle to the left vertical wall surface W2. In order to protect the head SHD, a cooling wall WWL is cooled by the fast conduction of cooling water of a low temperature.
