Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for observing and repairing the inside of a high-temperature furnace such as various steelmaking furnaces and molten steel ladles, and for imaging the furnace wall and the inside of the furnace, and repairing the furnace wall as necessary. Regarding the device.

[0002]

2. Description of the Related Art The lining of refractory bricks and irregularly shaped refractory, which is applied to the inside of the steel shell of a steelmaking furnace such as a vacuum degassing furnace or a molten steel ladle, is gradually damaged with the operation. The condition is regularly checked, and if there is a damaged part, it will be repaired.

In order to check the damage state of the furnace wall, a heat insulating box that can be rotated and moved up and down is inserted in the high temperature furnace, and a TV camera is mounted in this heat insulating box to observe the furnace wall and display it on the CRT. The damage state is determined from the captured image. On the other hand, the visual field position and visual field range of the television camera are calculated based on the rotation angle and the ascending / descending distance of the cooling cylinder, and the output image of the calculation result is separately displayed on the CRT. Therefore, when the repair required part is confirmed from the captured image displayed on the CRT, the screen of the CRT is switched to the above output image, the visual field position and the visual field range of the TV camera are read from the screen, and the repair map over the entire furnace wall is displayed. create. Then, after calculating repair data such as repair position, range, and the number of times the refractory material has been sprayed from the repair map, performing labeling, correction, etc. as necessary, and then instructing the control sequencer of the repair machine based on this, We are repairing the wall.

[0004]

However, with the conventional means of deciding the necessity of repair while observing the furnace wall and inputting the repair data based on the repair map, there are many time losses and setting errors. In addition, there is a problem in that, and since the calculation for efficient repair cannot be performed quickly, the efficiency is lowered. Therefore, the present invention prevents a setting error that occurs when inputting repair data,
It is an object of the present invention to solve various problems that have occurred in the prior art, such as the troublesomeness of calculating repair data and time loss.
