PURPOSE:To decrease rebound loss and to extend service life by projecting a repair cooling plate at a close space between the existing cooling plates in the shell part where refractory lining is dislodged and thermal load is increased then forming a lining layer. CONSTITUTION:A repair horizontal cooling plate 30 of a projection type is mounted at a close space between the adjacent existing horizontal cooling plates 3 in the shell 1 part where refractory lining is stripped and thermal load is increased. Inside circumferential projecting racks 6 in a horizontal direction are formed into an optional number of steps by such plate 30 and the above- described cooling plates 3. A lining layer 11 is formed on the racks 6 by spraying castable refractories 9 from a nozzle 8 thereto. The utilization of refractories which fail thus far to be effectively utilized is made possible by the above- mentioned method, by which rebound loss is decreased. The lining layer 11a is also supported by said racks 6, by which the service life is extended. |
