摘要： An impeller as used in a projecting construction apparatus for a concave section of a molten-metal-discharging hole is supported on a rotating shaft for redirecting flow of impinging projection material. The impeller includes a plurality of vanes which are attached to the rotating shaft with a specified twisting angle relative to the rotating shaft. A material supplying pipe is directed upon the plurality of vanes, so that, upon impingement of the projection material upon the plurality of vanes, the projection material is projected outwardly and in a direction nearly opposite to the predetermined direction of impingement of the projection material supplied through the material-supplying pipe.

摘要： 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.

摘要： The lining of a furnace is automaticlly repaired by use of a movable transport car on which a vertically disposed spray pipe is capable of being vertically displaced along its longitudinal axis and of being rotated about its longitudinal axis. The transport car is moved to a position underlying a furnace, and the spray pipe is elevated into the furnace to thereby dispose a spray nozzle on the end of the spray pipe within the furnace. The spray nozzle is directed to spray refractory material onto the abraded, eroded, and spalled areas of the refractory lining within the furnace.

摘要： 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.

摘要： A lining apparatus of this invention is characterized by having a TV camera at a desired portion of a spray pipe and a monitoring device which is located outside of a furnace. The TV camera has a visual range directed toward the same direction as that of the spray nozzle. Due to the above construction, a clear image of an eroded portion of the furnace lining can be continuously observed by the monitoring device throughout the spraying operation. Accordingly, an operator can conduct a considerably accurate and safe lining operation.

摘要： A gunning apparatus for repairing a furnace lining is provided with a spray pipe of non-circular hollow cross-section. The spray pipe of non-circular cross section slidably moves back and forth within a rocking sleeve by a slide mechanism while the spray pipe is non-rotatable relative to the slide mechanism and is rotatable only by the rotation of the slide mechanism, whereby the shooting pipe is manipulated without weakening the rigidity or strength thereof which usually occurs on a conventional circular shooting pipe which requires keyways for rotation thereof.

摘要： This invention discloses a method which can efficiently repair the tap hole of a converter even under high temperature. The method employs an injection pipe of a unique construction for applying refractory material onto the inner surface of the tap hole. Such injection pipe is of a circular cylindrical construction and is provided with a pipe cooling means and, preferably, with a perforated mold sleeve which encases the injection pipe. Due to such construction, the refractory material charged into the injection pipe can be smoothly and uniformly injected through an injection opening formed at the front portion of the injection pipe and apertures of the perforated mold sleeve onto the inner surface of the tap hole, whereby thus applied refractory material can show the improved adhesion rate and properties while defining a predetermined optimal diameter to the tap hole after the repairing operation.
