Definitions
- ABSTRACT There is provided a mounting structure in which a guide arm is arranged on each of two sides of a sliding nozzle unit mount in the bottom of a ladle, and the housing of a sliding nozzle unit is provided with a roller on each one of two sides thereof, whereby the rollers are moved on the guide arms to mount the sliding nozzle unit on the nozzle mount.
- the present invention relates to a sliding nozzle unit mounting structure and more particularly to a mounting structure for a sliding nozzle unit of the type which is mounted as a unit on the bottom shell of a ladle.
- a disadvantage of such mounting operation is that the mounting operation requires much time and labor due to complicated positioning work, etc., and moreover the operation requires almost exclusive use of the crane or the like thus frequently preventing the smooth progress of other operations.
- FIG. 1 is a front view of an exemplary sliding nozzle unit incorporating an embodiment of the present invention.
- FIG. 2 is a left side view of FIG. 1.
- FIG. 3 is a front view of the bottom portion ofa ladle at which the sliding nozzle unit of FIG. 1 is mounted, the ladle being placed with its bottom surface standing vertical.
- FIG. 4 is a side view of FIG. 3.
- FIG. 5 is an enlarged perspective view of the guide arms used in the embodiment of the invention.
- a sliding nozzle unit 1 is provided with a pair of rollers 4 which are mounted on supporting arms 3 arranged on both sides of a housing 2.
- numeral 5 designates collector nozzles, 6 a turning gear, 7 locking bolt holes.
- a pair of guide arms 10 are provided on both sides of a nozzle mount 9 at the bottom of a ladle 8 to extend therefrom so that the rollers 4 may be moved on the guide arms 10.
- numeral 11 designates nozzle hole
- numeral 12 designates driving means for driving the turning gear 6
- numeral 13 designates eye bolts hinged to nozzle mount 9 at one end of the bolt and fix the nozzle unit at the bolt hole 7 at the other end of the bolt to fasten the sliding nozzle unit 1 in place.
- each guide arm 10 is preferably constructed so that its entire length is divided into two parts.
- a forward portion 10 is fit on the guide arm 10 to increase its length and it is removed upon completing the mounting operation, thus reducing the length of the guide arm 10 that extends from the shell of the ladle bottom and preventing the occurrence of any inconvenience to the pouring operation of molten steel.
- the manner of arranging according to the present invention is as follows.
- the ladle is placed with the bottom surface standing vertical and in the posture as shown in FIG. 3, the nozzle unit 1 is raised by means of for example the hooks of a crane which catches the supporting arms 3 and the nozzle unit 1 is then lowered in such a manner that the rollers 4 of the nozzle unit 1 engage with the grooves of the guide arms 10 projecting from the ladle bottom.
- the setting height of the guide arms 10 is preselected so that the nozzle unit 1 thus lowered is properly positioned.
- the sliding nozzle unit incorporating the illustrative embodiment of this invention is of the unit type which comprises a stationary plate, a sliding plate having collector nozzles and pressing means and which is adapted to be mounted as a unit.
- the present invention has among its remarkable advantages the fact that there is no need to continuously suspend a sliding nozzle unit by means of for example crane until the completion of the mounting operation and hence the time during which the crane is occupied by the mounting operation is reduced, thus eliminating the danger of deteriorating the efficiency of other operations and improving the operation efficiency of the field work.
- said nozzle unit housing comprising a stationary plate; and a slidable plate for mounting nozzles of said nozzle unit, the surface of said stationary plate extending in parallel with the surface of said ladle on which it is mounted.
