率の低下という問題が発生しなかった。Conventionally, in continuous annealing and pickling equipment for horizontal linear arrangement of stainless steel plates, abrasive projection devices are installed above and below the traveling steel plate to remove scale by projecting the abrasive onto the upper and lower surfaces of the steel plate. However, the processing speed (traveling speed) of the steel plate is slow at 30 to 50 m/min (and the number of abrasive projecting devices is small, about 2 per side, so the abrasive material is not projected even on the top surface of the steel plate. There was no problem of reduced cleaning efficiency due to mutual interference between the abrasive materials.

けるという不具合点があった。However, when a high steel plate processing speed of 200 to 400 m/min is required, in a horizontally arranged continuous annealing and pickling equipment, the top surface of the running steel plate (strip) is sprayed with a blasting device to remove scale. Throw sweepers,
Furthermore, projecting the abrasive material onto the top surface of the steel plate downstream means that the abrasive material projected onto the top surface of the steel plate from the upstream projection device is not removed from the top surface of the steel plate yet. Since the abrasive material is projected, the abrasive material projected earlier and the abrasive material projected later interfere with each other, significantly reducing the grinding efficiency, that is, the scale removal efficiency.
In addition, the length of the scale removal device is also long (
There was a drawback that there were restrictions in terms of construction, building, and other installations.

The strip S is configured as described above, and the strip S passes through an unwinding machine, a welding machine, an inlet strip storage device (accumulator), etc. (not shown), travels at a predetermined speed, and is passed through a tensioning device 2 into a box shape. Enter the lowermost compartment 6 of the frame 1, where the abrasive material 3 from the projection devices 11, 12, 13
1 is projected onto its underside to undergo a descaling action, and then the strip S is turned over by a deflector roll 24 and enters the compartment 7. Then, here the projection devices 17j, 1
The abrasive material 61 from 5 and 16 is projected onto the lower surface (the upper surface within the compartment 6) to undergo a descaling action. The strip S is then reversed by the deflector roll 25 and enters the compartment B, where it is descaled by projecting the lower surface (the upper surface in the compartment 7) with abrasive material from the projection device 17, 18, 19. is then turned around by a deflector roll 26 and enters the compartment 9, where the projection devices 20, 21, 22
After descaling the lower surface (upper surface in compartment 8) with abrasive material from the deflector roll 27.28
.. 29, it reaches the tensioning device 3o, and is sent to the next process. On the other hand, the scale-containing abrasive material 31 that has been descaled as described above is collected in the hopper-shaped part 2 at the bottom of the box-shaped frame 1, and then sent to an abrasive material recovery facility (not shown). The abrasive material is separated from the scale, and sent again to each abrasive projection device for circulation.

化するようなことが全くない。Strip descaling device of the present invention &'! According to the present invention, (1) the abrasive material that has been projected onto the strip S and has been descaled immediately falls onto the upper surface of the strip S. Since there is no residual material, there is no possibility that the abrasive material projected earlier and the abrasive material projected later will interfere with each other.Therefore, the cleaning rate decreases and the scale increases. There is no deterioration in removal efficiency at all.

Since it is designed to be ground, scale removal performance is improved, and it does not require a long installation space as in the past.

In addition to being effective, it also has the advantage of further enhancing the descaling effect.

This example is effective for reducing the load on scale removal equipment, treating special steel that does not easily remove scale, and when a particularly severe surface finish is required. This is what we do. In this case, although not shown in the drawings, it goes without saying that a cleaning tank and a dryer are installed on the downstream side of the pickling tank 5'5.
