APPARATUS FOR BUILDING UNBURNED REFRACTORY

摘要

An apparatus for building an unburned refractory for improving work environment and work efficiency of workers and preventing the occurrence of non-uniformity of spray thickness, characterized by comprising a container (1) for a molten metal (ladle, etc.) repaired so that spray and casting can be carried out by one apparatus, a rail (2) laid down in the proximity of the container (1), a truck (4) so mounted on the rail (2) as to be capable of travelling, a transverse truck (7) capable of travelling in an orthogonal direction to the travelling direction of the truck (4), a support pole (8) planted to the transverse truck (7), an elevation frame (10) so fitted to the support pole (8) as to be capable of moving up and down, a material feed pipe (9) inserted into the upper part of the elevation frame (10), a spray nozzle (27) (or discharge pipe (39) for casting) replaceably fitted to the lower distal end of the material feed pipe (9) protruding from the lower part of the elevation frame, and bend/support means (20) provided to the material feed pipe (9) on the upper side of the elevation frame (10) and following up the elevation of the elevation frame (10).
