gates. A cantilever crane 12 and pallets 13 and 14 are mounted between both branches 4 and 5 for storing parts of the valve.

Further, a furnace 15 for drying the refractory elements of the gate, a device 16 for assembling the valves, a device 17 for testing the valves and a valve 18 dt for transporting the assembled elements to the furnace 15 and back are located.

The stand 2 for disassembling the closures (FIGS. 1 and 4) consists of a turntable 19 with pins 20 with wedges mounted on it (FIG. 4). The table can be rotated on the frame 21 and provided with an actuator 22 (FIG. 1). Device 3 For extrusion of refractories from the gate (Figs. 1 6 and 9) consists of a removable stop 23 installed in a movable frame 24 fixed in the guides 25 (Fig. 9). The frame 24 is connected to the rods of the hydraulic cylinders 26 mounted on the bed 27 On the bed rails 28 there is a movable platform 29 filled with a through central hole and can be rolled out into the working area, and at the same time its surface is the working surface as a matrix. , during the process of pressing out of the shutter of refractory plates For receiving bo-refractories under the platform, an unloader 30 with a duct 31 is mounted on the wheels

The tilters 6 and 7 of the section for hoisting of the movable part of the slide gate are identical in design and made in the form of a swing frame 32 (Fig. 5) with folding replaceable strips, upper 33 and lower 34, intended for mounting, fixing and removing the movable slide gate. tuck or steel bucket after it is rotated by 180 °. For fixing the latter on these elements, folding bolts 35 and 36 are provided. Tilters 9 and 10 of the section for preparing the slide gate bodies differ from the size and configuration of the upper and lower minutes removable slats and are intended for mounting, fixing and removal of the valve body after rotation through 180 ° slats is altered by replacing the valve body during service stale- tundish or pouring.

The device 8 (Figs. 1.3 and 8) for pressing the refractories into the movable slide of the gate consists of a pin 37, mounted console on a rack 38 connected at the base with a hydraulic actuator rod 39 The base of the rack is mounted movably in rails 40 rollers 41, the stops of which are attached to the horizontal frame 4; the device 11 for

Pressing the refractories into the bodies of the slide gates is made similarly to device 8 and differs only in that its rollers 43 (FIG. 7) are made solid,

and it is more rational to install the shutter case design

The gate test device 17 (FIG. 1) comprises a frame 44 with pins for fastening the gate and a hydraulic cylinder 45 Actually a slide gate (FIG. 4J consists of a housing 46 with a refractory plate 47, a frame 48 and a movable gate 49 with a refractory plate 50 and a refractory cup 51

The casing 46 and the frame 48 are bolted 52 to the nuts 53. A loader 54 is installed for servicing the heating line.

Flow line works as follows

0 With the help of loader 54, the used slide gates enter the zone of action of the load-lifting mechanism 1. With it, the gate is mounted on the turntable 19 of the stand 2 for disassembly

5 valves At the same time, the mounting holes in the valve body 46 are aligned with the table pins 20 and fixed with wedges (FIG. 4). The ON / OFF key is turned on the 22 table 19 with the gate fixed on it

0 180 ° The horizontal position is maintained by the brake of the drive. Then the nuts 53 and bolts 52 connecting parts of the bolt are removed, the housing 46 and the frame 48 are then removed alternately by mechanism 1.

5, the frame 48 and the movable gate 49. Then, using the actuator 22, the table is turned again and to the initial position, and the wedge is removed from the slots of the pins 20 After that, the body 46 is removed by the same mechanism 1

0 shutter with turntable pins 20 19.

Movable gate 49 removed from the table and

housing 46 by the same mechanism alternately

. fed to the extrusion device 3

Refractories Vypressovku perform as follows Housing or movable gate installed on the platform 29, which is then along the rails 28 is moved until rex until the refractory axis 23 is aligned with the axis of the hole in the refractory plates

0 shutter elements. By turning on the hydraulic cylinders 26, the frame 24 is lowered with an emphasis 23 and the refractories are pressed out of the shutter elements. In this case, the refractory bout enters the duct 31 through a hole in the movable

5 to the platform and then on the unloader 30 is transported to the zone of action of the load-lifting mechanism 1. By the same mechanism, the valve body 46 is mounted on the tilting device 9, and the sliding slide valve 49 is placed on the tilting device 6. In the initial position, for example.

for the movable gate (figure 5), the swing frame 32 and the bottom flap 34 are in a horizontal fixed position, the top flap 33 is rotated against the stop. A movable shutter 49 is installed on the lower folding bar of the turn-off device or on the lower folding bar of the turn-off device 9 the valve body 46. Then turn the bar 33 and with the help of hinged bolts 36 press it to the pivoting frame 32. thereby fixing the gate element 49 or 46. Then the frame 32 turn-over device is rotated 180 ° until it stops and fixed. After that, release the bolts 35, turn the frame 34 to 18C ° until it stops. After that, the housing 46 or the movable gate 49 is transmitted respectively to the roller table rack 4 or 5. Further, for example, the valve body 46 is fed to the device 11 for pressing the refractories. Accordingly, the movable gate 49 enters the device 8 for the same purpose B mounted on the rollers 41 or 43 parts of the slide gate with the help of pen 37 press fireproof plates. To do this, include hydraulic actuators 39 which, along the guides 0, lower the column 38 with the fastened M3. Then the shutter elements are released by turning on the hydraulic actuators on the rise and along the roller table racking, m 5 or 4 are transferred to tilters 7 or 10. At the tilter 10 they are turned to a position suitable for drying and assembling the solution. Then the elements 46 and 49 are removed, put in the appropriate pallets 13 and 14 and with the help of a crane 18 is fed to the furnace 15 for drying. After drying, the same valve from the furnace, the lined valve bodies 46 and movable gates 49 are fed into the zone of action of the cantilever crane 12 and transferred to the valve assembly device 16 after cooling. The valve is assembled in the reverse order of disassembly on the bench 2. Assembled shutter

a crane 2 is mounted on the frame 44 of the device 17 for testing the valves, aligning the holes in the valve body 46 with the pins 20 installed and fastening them with wedges.

fu by analogy with stand 2 and device 16. After that, the stem of hydraulic cylinder 45 is connected to the sliding gate gate 49 and the gate is moved forward and backward by turning on the cylinder, controlling

with pressure gauges. The necessary force of movement of the movable bolt member is achieved by tightening or loosening the respective nuts on the bolt. After testing the shutter

crane 12 is removed from device 17 and, with the help of loader 54, is directed to the place of storage or operation,

The use of the proposed production line allows increasing the level of mechanization and labor productivity.
