Abstract
Refractory material in wet slurry form is applied onto the inner surface of a furnace. The improvement is characterized in that the water to be added into the powder-like refractory material for producing the above slurry refractory material is finely and accurately regulated so that the resultant refractory material sprayed from the spray nozzle fixedly adheres onto the abraded or eroded portion of the inner surface of the furnace with a minimum amount of rebound loss.
