专利摘要:
A refractory plate-frame assembly for use in a sliding closure unit includes a frame having therein a recess and a refractory plate positioned within the recess. A flexible band is mounted within the recess about the periphery of the refractory plate. A tightening device is mounted in the frame and is selectively operable from the exterior thereof to tighten the band about the periphery of the plate and thereby securely mount the plate within the recess, and alternatively for loosening the band from the periphery of the plate, whereby the plate may be removed from the band and the frame.

The invention relates to metallurgy, in particular to the casting of metal from metallurgical vessels with slide gates.
The aim of the invention is to facilitate the replacement of refractory plates.
FIG. 1 shows a device in perspective; in fig. 2 shows an embodiment of a frame with a bottom plate; the view of Cepxyt in FIG. 3 is the same section in FIG. 4 - section A-A on. FIG. 3 | in fig. 5 is an embodiment of the lock lock} in FIG. 6 — a variant of the construction of the slide plate mounted in the frame of the gate, top view; in fig. 7 is a section BB in FIG. 6j in FIG. 8 - a frame of a rotary gate with a plate fixed in it, top view.
In frame 1 (Fig. 1), which is a fixedly mounted cassette designed for placing the bottom plate in it, there is a linear recess 2 with a support block 3c on one side and a clamping block 4 located on the opposite side, driven by a screw for 5 seconds. left and right thread. In recess 2, along its perimeter, there is a bandage arm 6 with fixed locks.
7 on the sides. Inside the slide gate in the tape, the refractory plate 8, which performs the function of a fixed base plate, is placed, which is crimped with the help of lock locks 7, actuated by screws during rotation of the knobs 9. Final fixing of the plates
8 between the support 3 and the clamping 4 pads is carried out by rotating the adjustment screw 5.
On the sides, the tape 6 is divided into two parts, one of which is fastened to the support 3 with the help of rivets 10, and another 4 to a clamping shoe (fig. 2). In the intervals between the ends of the tape segments facing each other, there are backward locks 11, which are coupled with the tension wedges of the 12 lock locks 7, which can be fastened or loosened with screws 13. At the same time, the tension wedges 12 fit to the guiding surfaces of the recess 2 of the frame 1. The set screws 14 serve to move the clamping block 4.
The device works as follows.
When the refractory plate 8 is worn, it is replaced with a new one, setting it in a position in which it is kept stationary between the support 3 and clamp 4 pads during operation, which protects it from wear due to the frictional forces that occur when the shutter opens and closes. It is fastened with a bandage tape 6 against the effect of internal stresses. The pressure exerted by the tape 6 is evenly distributed around the entire perimeter of the plate 8.
One tension wedge 12 is made in the form of a threaded sleeve, which can move along a thread that is on the end of a screw with a shoulder 15 (Fig. 3 and 4). Another tension wedge 12, made in the form of a sliding sleeve, is located on the smooth part of the screw 13 and presses against the ledge 15. As the driving screw of the tightening screw 13 rotates using the handle 9, one tensioning wedge 12 moves along the thread in the direction of the other wedge, adjacent to the step 15, and pulled through the reverse wedge
11 tape 6. All 11 and 12 have a slot a through which they interact with the screw tightening screw 13. The angle of interaction of the tension 12 and 11 of the wedges is selected depending on the number of lock locks 7 and the degree pressing the bandage tape 6.
At the end of the screw 13 (Fig. 5) there is a threaded head 16 on which a handle 9 is rotatably fixed abutting against the flange of the flange of the screw 13: sleeve 17 serving as a support for one of the tension wedges 12. The other tension wedge 12, secured against possible rotation, for example, with a cotter pin, is attached to the end of the actuating tightening screw 13, which, when the knob 9 is rotated, moves axially so that the tension wedges
12 is pressed or retracted from the back wedges 11 fixed to the unbent ends of the belt 6.
FIG. 6 and 7 depict an embodiment of a slide gate frame 18 with a recess 19, in which there is a base 20 for accommodating a moving mechanism (not shown). Part 21 of the frame 18 with a cone bolt 22 can re31D1
bilge in axial direction. On this part of the frame one section of the retaining tape 6 is fixed. The other part of it is fixed on the frame 18 itself, for branding the refractory plate
23e linear dimensions. On the tape there are tensioned strips 7 and the screws 13, which drive them, of the construction described above.
FIG. 8 shows a device that can be used in rotating slide gates. In the round frame 24 of the rotating bolt, the bandage of the belt 6 with one tension lock 7 is placed, since, due to the round shape of the orgneous plate 25, the tape 6 is pressed against it with a force evenly distributed along the entire perimeter. Fixation plate 25 in the frame
24 is carried out by tensioning wedges 12 moving along the guide surface 26 in the recess 27 of the frame,
The tape 6 is preferably made in the form of a flexible steel tape. Chain ribbons and wire belts can also be used. Banding tape 6 can be used not only in frames with round or frost-refractory plates and plates, but also with oval or polygon-shaped plates.
