Next, the operation of the embodiment device will be explained. A suspension frame 13 is disposed at the top of the target converter 12, and the chain block 2 is suspended from the frame 13, and the apparatus of the present invention having a rotation rail 1 or less is charged into the furnace and suspended. Next, the furnace construction robot 8 is set to the work start level, and the robot 8 picks up the brick 15 on the lifter 14 that has been previously installed inside the furnace, and moves the brick to the circle of the furnace. Load on the circumference. Since the robot 8 can operate within a range corresponding to approximately 45° of the center angle of the furnace, once the brick loading on the circumference within this range has been completed, the robot 8
Turn it 45 degrees and start laying bricks again. In this way, when the loading on the furnace circumference and the vertical movement range of the robot 8 have been used up, the lifting device 2
After the entire device is pulled up to a predetermined distance by operating the device, the above-described operations may be repeated again. Since the diameter of the furnace becomes smaller as it approaches the furnace mouth, bricklaying is carried out by combining the above operation with an operation of moving the traversing cart 7 in the radial direction of the furnace. All of the above operations may be performed automatically via a control device such as the controller 16.
