The present invention easily discharges the scale generated from the strip passing through the roller of the delay table during hot rolling, and rises from the scale sluice. The present invention relates to a windbreak insulation device for strips installed on a delay table for completely suppressing the occurrence of scale since the cold wind is completely blocked as much as possible to reduce the temperature deviation of the upper and lower portions of the strip.

There are two types of conventional strip wind insulation device, a fixed damper structure and a heating plate structure.

In the first fixed damper structure, a plurality of rollers 51 are provided at a predetermined interval on the delay table 50 as shown in (a) of FIG. 1 and FIG. 2, and the upper and lower parts of the plurality of rollers 51 are arranged at regular intervals. There is an automatic opening and closing of the top of the roller 51 " "Thermal heat insulating cover 40 is installed, and a cooling nozzle 52 for cooling the roller 51 heated by the strip 6 is installed at the lower end thereof, and the roller 51 and the roller 51 are installed. A fixed damper 53a is formed between two iron pieces in a “y” shape to prevent cold air rising from the scale throughs 55 from entering the lower end of the strip 6, and the “y” shaped damper ( 53a), a constant gap 54 was formed, and the scale fell to the gap 54.

And, the second heating plate structure is the same as the first fixed damper structure as shown in (b) of FIG. 1 and FIG. 2, but only the "y" shaped fixed damper installed between the roller 51 and the roller 51. (53a) Instead, "The hot plate 53b was provided so that the cold air which rises from the scale throughs 55 may not flow in into the lower end part of the strip 6. As shown in FIG.

However, in such conventional strip windshields, "Thermal insulation cover 40 has a strip (6) The heat dissipation effect is inferior because it passes through a large space load end of the " type. In the case of FIG. 2 (a), a gap 54 is formed between the " y " Since it does not block the cold air rising from the scale through (55) and flows into the gap (54), it is not possible to suppress the generation of scale due to the defect of the plate due to the temperature deviation of the upper and lower strips (6). (Miss Roll) is formed and at the same time the scale larger than the gap 54 is dropped on the “y” shaped fixed damper 53a, it is not discharged to the gap and is stacked on the “y” shaped fixed damper 53a as it is, and the roller 51 Since the scratches occur at the lower end of the trip 6 passing through the upper end of the), there is the inconvenience of frequently removing the scale by the attraction force.

In addition, in the case of FIG. 2 (b), up to the middle portion between the roller 51 and the roller 51 " "Type heating plate 53b is installed, so that cold air rising from scale through 55 can be blocked," "There is no structure for discharging the scale accumulated on top of the type heating plate 53b, so the scale is" "When the stack is stacked high on the top of the heating plate (53b) as it is, the lower end of the strip (6) passing through the upper end of the roller (51), this also has a cumbersome problem of removing the scale from time to time.

The present invention has been devised to solve such a conventional problem, and in particular, it is easily discharged automatically by using the weight of the scale generated from the strip, and at the same time, it blocks the cold air rising from the scale through as completely as possible. It is an object of the present invention to provide a windbreak insulation device for a strip installed on a delay table for improving the production rate of the strip by reducing the temperature variation of the upper and lower parts of the substrate.

In order to achieve the object of the present invention, a structure for attaching the heat insulating plate plated with chromium (Cr) integrally on the lower end of the heat insulating cover, and the plated chromium plated on the roller and the two sets of auxiliary plates The steel plate of the tank is compressed to form a windproof damper in the form of a "V", and the top of the lower plate between the other iron plate and one side of the iron plate is possible to be configured with a turnbuckle (Turn Buckle) and a protective cover is provided with a protective cover.

Hereinafter, the embodiment according to the present invention will be described in detail.

The present invention, as shown in FIGS. 3 to 6, is configured to integrally attach the thermal insulation plate 41 plated with chromium (Cr) to the lower end of the thermal insulation cover 40, and is placed between the rollers 51. Windproof damper 10 which is condensed to the two auxiliary plate 20 and the two auxiliary plate 20 and formed in a "V" shape, and a turnbuckle between the other side plate 10a and one side plate 10b. 32 and the spring 30 provided with the protective covers 31a and 31b are connected.

The "V" shaped wind damper 10 is configured to form a "V" is formed of two iron plates (10a, 10b) formed in a square or rectangular shape to be condensed to the two sets of standing plates 20 to be described later. On the upper ends of the two iron plates 10a and 10b, a door 11 provided with a hook 12 is fastened with a plurality of bolts, and is configured to be detachable to facilitate replacement of the spring 30 to be described later. The upper surface portions of the two iron plates 10a and 10b are plated with chromium (Cr).

The pair of auxiliary plates 20 is fixed between the roller 51 and the roller 51 in a vertical state and fixedly fixed so that the fixed damper 10 is formed in a “V” shape at an intermediate position thereof. The stopper 21 is inclined at a predetermined angle on both upper ends so that the spring 30, which will be described later, is prevented from being lifted by the lower ends of the "V" shaped wind dampers 10 by tension. do.

The spring 30 is installed on the upper surface of the other side iron plate (10b) and one side iron plate (10a), both ends of the spring 30 is fixed to the inner surface of the protective cover (31a, 31b), the one side protection The cover 31a is provided with a turnbuckle 32 which is tension-adjustable, and connecting rings 33a and 33b are provided at both ends of the protective covers 31a and 31b, and the connecting rings 33a and 33b are doors 11. The hook 12 is hooked to a configuration that is connected.

The heat insulating plate 41 plated with chromium is integrally attached to the lower end of the heat insulating cover 40, and the heat insulating plate 41 is most preferably maintained at a distance of 244 mm from the upper part of the roller 51. .

Reference numeral 42 is a connecting portion connecting the heat retaining cover 40, 43 is a cylinder connected to the heat retaining cover connection to open and close the heat retaining cover 40.

The operation and effects of the implementation structure according to the present invention configured as described above will be described.

That is, according to the present invention, as shown in FIGS. 3 to 6, the thermal cover 40 may be removed from the heat insulating cover 40 before the strip 6 passes over the roller 51 of the delay table 50 during the hot rolling operation. The cylinder 43 is operated in the virtual line state to descend to the solid line state of FIG. 3 so that the strip 6 passes over the roller 51 of the delay table 50 in a state of being covered and sealed on the roller 51.

As described above, the upper end of the strip 6 passing through the roller 51 is heat retained by the strip 6 to the heat insulating plate 41 plated with chromium (Cr) attached to the lower end of the heat insulating cover 40. By re-reflecting the strip 6, the heat retention effect is increased, and at the same time, the scale generated at the lower end of the strip 6 blocks the cooling water and cold air rising from the cooling nozzle 52 and the scale through 55. The “V” shaped wind damper 10 is piled apart to the top.

At this time, the "V" shaped wind damper 10 does not open the "V" shaped wind damper 10 until a certain amount of scale is accumulated by the tension of the spring 30, the "V" shaped wind damper 10 When the appropriate amount of scale is accumulated on the upper end of the scale, the "V" shaped wind damper is automatically rotated by the weight of the scale from the solid line state of FIG. Strip 6 by easily blocking the coolant and cold air rising from the cooling nozzle 52 and the scale through (55) while returning to the original state by the tension of the spring 30 in a solid line state in FIG. By keeping the lower end of the scale generation can be suppressed to the maximum.

On the other hand, since the chromium (Cr) is plated on the upper end of the "V" -shaped wind damper 10, the heat emitted from the strip 6 is reflected back to the strip 6 to further increase the heat dissipation effect. 6) By reducing the temperature deviation of the upper and lower parts as much as possible to prevent the mis-roll by removing the bad strip (6).

The present invention as described above, unlike the conventional strip emitting heat retaining device, a spring that is automatically opened and closed by the weight of the scale and the configuration of integrally attaching the heat insulating plate 41 plated with chromium (Cr) on the lower end of the heat retaining cover 40 The “V” shaped wind dampers 30 connected to each other are condensed to the two sets of auxiliary plates 20 so that the coolant and the cold air rising from the cooling nozzle 52 and the scale through 55 are completely as possible. It is a practical design that has the effect of improving the production rate of the strip by blocking and reducing the temperature difference of the upper and lower parts of the strip 6 to suppress the occurrence of scale and automatically discharged by the weight of the scale.
