ABSTRACT:
A lining apparatus of this invention is characterized by having a TV camera at a desired portion of a spray pipe and a monitoring device which is located outside of a furnace. The TV camera has a visual range directed toward the same direction as that of the spray nozzle. Due to the above construction, a clear image of an eroded portion of the furnace lining can be continuously observed by the monitoring device throughout the spraying operation. Accordingly, an operator can conduct a considerably accurate and safe lining operation.
