Abstract
In an apparatus which applies refractory material in either wet or dry form onto the inner surface of a furnace by means of a spray pipe, a rotating mechanism for rotating the spray pipe is provided with an automatic oscillating device for automatically effecting a continuous oscillation of the spray pipe, the continuous oscillation improving the operability of the spraying operation while uniformly applying an optimal amount of refractory material onto the inner surface of the furance.
