Abstract
A method and apparatus for repairing lining which comprises transmitting microwaves modulated by an antenna inserted into the vessel to the surface of the heated refractory lining in the refractory lined vessel, detecting the reflected waves, detecting the difference between the reference surface of the refractory lining and the damaged surface from the phase difference of the microwaves, controlling the transfer of the refractory gunning nozzle inserted into the vessel with the use of the deviation signal, and making the lining repair in the hot atmosphere.
