Detailed Description
Although the embodiments of the flow distributor supporting tool and the twin roll continuous casting apparatus using the same according to the present invention are described with reference to the drawings, the present invention is not limited to the embodiments described with reference to the drawings.
(Main embodiment)
A main embodiment of a flow distributor supporting tool and a twin roll continuous casting apparatus using the same according to the present invention will be described with reference to fig. 1 to 5.
In FIG. 1, 110 is a casting roll, 120 is a tundish, 130 is a distributor, 140 is a distributor support fixture, 151 is a swinging guide plate, 152 is a guide roll, and 153 is a pinch roll.
The casting rolls 110 are arranged in pairs facing each other so that the axial direction thereof faces the horizontal direction, and can form a molten pool 111 by a space surrounded by side seal plates (not shown) arranged in pairs on both axial end sides thereof in cooperation with each other.
The tundish 120 is disposed above the casting rolls 110, stores therein the molten metal 1 supplied from a ladle (not shown), and is capable of delivering the molten metal 1 from a tubular tundish nozzle 121 at the lower portion.
The distributor 130 is disposed between the casting rolls 110 and the tundish 120, and detachably supports the flange portion 130b on a distributor support 140 (described later in detail) so that the tip end thereof is placed on the molten pool 111, and the tundish nozzle 121 of the tundish 120 is inserted inside, and the molten metal 1 from the tundish nozzle 121 is distributed and supplied from the supply port 130a to the molten pool 111 uniformly in the axial direction of the casting rolls 110.
The swing guide 151 is disposed below the casting rolls 110, and has a base end portion supported swingably so as to be switchable between a guide position for guiding the strip 2 fed from the casting rolls 110 from the vertical direction to the horizontal direction and a retracted position. The retreat position is a position that is separated from the strip 2 and ends the guidance after the conveying direction of the strip 2 is switched.
A plurality of guide rollers 152 are arranged in the horizontal direction in such a manner that the conveying direction of the web 2 is switched to the horizontal direction by the swing guide 151 and then the web 2 is guided in the horizontal direction.
The pinch rollers 153 are disposed so that the axial direction is aligned horizontally and paired in the vertical direction on the downstream side of the guide rollers 152 in the conveying direction of the strip 2, and the pinch rollers 153 can convey the strip 2 guided by the guide rollers 152 while sandwiching the two rollers therebetween.
As shown in fig. 2 to 4, the flow distributor supporting tool 140 has the following configuration.
A rectangular sub-frame 142 made of ordinary steel is fixedly supported at a plurality of locations via bolts 143 inside a main frame 141 made of ordinary steel assembled in a rectangular shape in plan view. On the inner sides of the sub-frames 142 on both axial end sides of the casting rolls 110, grooves 142a (see fig. 4) are formed, which are notched in the horizontal direction perpendicular to the axial direction of the casting rolls 110.
Inside the sub-frame 142, two support beams 145 made of ordinary steel and having a longitudinal direction along the axial direction of the casting rolls 110 are disposed in pairs in an upward direction, which is a horizontal direction perpendicular to the axial direction of the casting rolls 110.
On both end sides of the support beam 145, convex portions 145a loosely fitted into the concave grooves 142a of the sub-frame 142 are formed, respectively. The protrusions 145a of the support beam 145 are loosely fitted into the grooves 142a of the sub-frame 142, respectively. Thereby, the support beam 145 is supported so as to be movable with respect to the sub-frame 142.
One end side of support frame 144 made of ordinary steel is connected and fixed to the middle of support beam 145 in the longitudinal direction. The other end side of the support frame 144 is fixed to the inner surface of the sub-frame 142 in the direction orthogonal to the axial direction of the casting rolls 110.
That is, the support frame 144 restrains the middle portions of the support beams 145 in the longitudinal direction so that the support beams 145 can be displaced only on both end sides with respect to the sub-frame 142.
On the opposite surface sides of the pair of support beams 145, an attachment portion 146a bent in an L shape above the support arm 146 made of heat-resistant steel is attached at one point only by a bolt 147, wherein the support arm 146 has a longitudinal direction directed in the vertical direction and a width in the longitudinal direction of the flow distributor 130 is narrowed to a degree capable of sufficiently supporting the weight of the flow distributor 130 and the supplied molten metal 1.
The support arms 146 are paired between the opposing support beams 145, and the paired groups are disposed on both sides of the support beams 145 in the longitudinal direction (two groups: four in total are used in this case).
Support portions 146b are formed on the lower side of the support arms 146, and the support portions 146b are bent in an L-shape so as to engage with the flange portions 130b of the current distributor 130 and detachably support the current distributor 130. The height position of the support portion 146b of the support arm 146 is set so as to be located above the molten pool 111, i.e., above the upper portion of the casting roll 110.
That is, the support arm 146 is engaged with and supported by the flange portion 130b of the current distributor 130 via the support portion 146b, so that the supply port 130a of the current distributor 130 is positioned in the molten pool 111, and four support arms 146 in two pairs are supported at four positions (four points) of the current distributor 130.
In the present embodiment, the main frame 141, the sub-frame 142, the bolt 143, the support frame 144, and the like constitute a frame. In fig. 2 and 3, reference numeral 148 denotes a heat insulating plate.
In the twin-roll continuous casting apparatus 100 using the distributor support tool 140 according to the present embodiment, when molten metal 1 is supplied from the ladle into the tundish 120 and the molten metal 1 is fed from the tundish nozzle 121 into the distributor 130, the molten metal 1 is distributed and supplied from the supply port 130a of the distributor 130 to the molten pool 111, and is cooled by the casting rolls 110 and sent downward to form a strip 2.
The strip 2 is nipped between the pinch rollers 153 via the swing guide 151 and the guide roller 152, and is further conveyed to a subsequent process. Further, after the strip 2 is nipped between the pinch rollers 153, the swing guide 151 moves to the retreat position.
Before the molten metal 1 is continuously cast in this manner, the distributor 130 is preheated at other positions, then conveyed to above the distributor support tool 140 and lowered, and the flange portion 130b is supported at four positions by the support portions 146b of the support arms 146 (four-point support). Thus, the deflector 130 is detachably supported by the deflector support device 140 while being prevented from rotating about a vertical axis and swinging about a horizontal axis.
At this time, the heat of the preheated flow distributor 130 can be transferred to the support beams 145 only from the four support arms 146 which are narrow in the longitudinal direction and have a contact area reduced to the minimum necessary. Therefore, since the temperature decrease of the flow distributor 130 is suppressed to a large extent, the heating temperature during the warm-up can be significantly reduced as compared with the conventional art.
Therefore, according to the present embodiment, the energy loss of the preheated flow distributor 130 can be suppressed to a large extent.
Further, since the support arm 146 made of expensive heat-resistant steel has a narrow width, that is, the amount of expensive heat-resistant steel used can be suppressed, the cost can be reduced.
Further, since the support arm 146 is attached to the support beam 145 at only one point by the bolt 147, even if the support arm 146 is thermally expanded, thermal displacement of the support arm 146 can be allowed without being restricted by the thermal expansion, and therefore damage to the support arm 146 due to the thermal displacement caused by the thermal expansion can be prevented.
Further, since the support beams 145 are supported by the projections 145a on both end sides loosely fitted into the grooves 142a of the sub-frame 142 and the longitudinal middle portions are rigidly coupled to the sub-frame 142 via the support frames 144, even if thermal expansion occurs, thermal displacement due to the thermal expansion is allowed to occur on both end sides as shown in fig. 5, and damage to the support beams 145, the sub-frame 142, and the like due to the thermal displacement due to the thermal expansion can be prevented.
Further, since the height position of the support portion 146b at the lower end of the support arm 146 is set above the molten pool 111 and also set above the casting rolls 110, even if the molten pool 111 is filled with the molten metal 1, the support arm 146 can be prevented from coming into contact with the molten metal 1, and damage can be prevented.
(other embodiments)
In the above-described embodiment, the pair of support arms 146 (two groups: four in total) between the opposing pairs of the support beams 145 are disposed on one side and the other side in the longitudinal direction of the support beam 145, respectively, and the flow distributor 130 is supported at four points, but as another embodiment, for example, only one support arm 146 may be attached to the middle portion in the longitudinal direction of one support beam 145, and one support arm 146 may be attached to each of both ends in the longitudinal direction of the other support beam 145, and the flow distributor 130 may be supported at three points by the three support arms 146.
In this case, for example, the two support arms 146 attached to the two ends of the other support beam 145 in the longitudinal direction are designed as a single support arm, that is, a double support arm having two support portions for supporting the flow distributor 130, and having only one attachment portion 146a attached to the support beam 145, so that the flow distributor 130 can be supported at three positions by the two support arms.
Further, in the above-described embodiment, the thermal displacement of the support arm 146 can be allowed without restricting the thermal expansion of the support arm 146 by attaching the support arm 146 to the support beam 145 by the bolt 147, but as another embodiment, for example, as shown in fig. 6, it is also possible to attach the support arm 246 to the support beam 245 by engaging the attachment portion 246a of the support arm 246 whose upper side is formed in an コ shape with the concave groove 245a of the support beam 245 which is opened upward in the longitudinal direction, so that the thermal displacement of the support arm 246 can be allowed without restricting the thermal expansion of the support arm 246.
Further, in the above-described embodiment, the convex portions 145a are formed on the end portions on one side and the other side of the support beam 145, and the convex portions are loosely fitted into the concave grooves 142a of the sub-frame 142, respectively, and the support beam 145 is supported by fixing and supporting the middle portion in the longitudinal direction of the support beam 145 by the support frame 144, but as another embodiment, for example, as shown in fig. 7A, a convex portion 345a of the support beam 345 having the convex portion 345a formed only on the end portion on one side (lower side in fig. 7A) is loosely fitted into the concave groove 342a of the sub-frame 342, and the end portion on the other side (upper side in fig. 7A) of the support beam 345 is fixed to the sub-frame 342, so that the support beam 345 can be supported.
As shown in fig. 7B, it is also possible to support one of the opposing pairs of support beams 445 by forming a convex portion 445a only on one end (the lower side in fig. 7B) of the support beams and loosely fitting it into the concave groove 442a of the sub-frame 442 and fixing the end on the other side (the upper side in fig. 7B) to the sub-frame 442, and to support the other support beam 445 by forming a convex portion 445a only on the end on the other side (the upper side in fig. 7B) of the support beams 445 and loosely fitting it into the concave groove 442a of the sub-frame 442 and fixing the end on one side (the lower side in fig. 7B) to the sub-frame 442.
Here, since the support beams 145, 245, 345, 445 apply a large amount of heat to the pair of opposing sides depending on the positional relationship between the tundish 120 and the flow distributor 130, etc., it is particularly preferable to support the support beams 445 by the sub-frames 442 as shown in fig. 7B because the extension width of the opposing gap due to thermal displacement (thermal deformation) caused by thermal expansion can be suppressed as compared with the case where the sub-frames 342 support the support beams 345 as shown in fig. 7A.
Further, according to the above-described embodiment, when the support beams 145 are supported by the sub-frame 142 and the support frame 144, the amount of thermal displacement of each end of the support beams 145 thermally deformed due to thermal expansion can be made half of the amount of thermal displacement of the end side thermally deformed due to thermal expansion of the support beams 345, 445 when the support beams 345, 445 are supported by the sub-frames 342, 442 as shown in fig. 7A and 7B, so that the support of each support beam 145 to the sub-frame 142 can be more reliably performed, and the area of the support portions 146B, 246B of the support arms 146, 246 contacting the flange portion 130B of the air distributor 130 can be reduced as compared with the case where the support beams 345, 445 are supported by the sub-frames 342, 442 as shown in fig. 7A and 7B, and the energy loss of the preheated air distributor 130 can be further suppressed, and is therefore particularly preferred.
Industrial applicability
The distributor supporting tool and the twin-roll continuous casting apparatus using the same according to the present invention can significantly suppress energy loss to the preheated distributor, and therefore can be used very advantageously in the iron manufacturing industry and the like.
