ABSTRACT:
A projecting construction apparatus for a molten-metal-discharging hole includes a rotating shaft and an impeller rotatably supported by the end of the rotating shaft. The impeller has vanes radially disposed and is open to fluid flow in a generally axial direction, such that gas flowing axially toward the impeller can pass substantially axially through the impeller without being deflected against a wall of the hole, while liquid and solid material are deflected by the vanes against the wall of the hole. At least two material-supplying pipes are located around the rotating shaft, and are connected to supply projection material entrained in a fluid to the impeller, and have ejection ports generally equi-angularly disposed about the shaft axis. The ejection ports are directed toward the vanes, and a plurality of control valves are connected to respective ones of the pipes so as to control an amount of the projection material which is supplied to each of the pipes. A moving arrangement is provided for moving an assembly of the rotating shaft, the impeller, and the pipes forward and backward inside the hole to be constructed, so that gas carrying the liquid and solid portion of the projection material is not directed against the wall of the hole, and so that substantially only the liquid and solid portion of the projection material is applied against the wall of the hole.
