Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cooling bed of a strip rolling facility for cooling rolled shape steel.
[0002]
[Prior art]
The long bar rolling mill for producing long shaped steel such as angle steel is composed of a rolling mill that rolls a flexible rolled material in a high temperature state into a predetermined cross-sectional shape and size, and a cooling bed that cools the rolled shaped steel. And. There are various types of cooling floors such as the lake type, scroller type, chain type, etc., but the lake type cooling floor is sufficient to prevent bending of the product that deforms the shape steel in the horizontal and vertical directions during cooling. It is often used because it has the advantage of being able to cool uniformly over a wide area.
[0003]
Conventionally, as shown in FIG. 11, the rake type cooling floor transfers a plurality of grooves 51 having inclined surfaces 51 a inclined at a predetermined angle α, and a shape steel 52 of each groove 51 to the adjacent grooves 51. And a moving rake (not shown). And according to this structure, predetermined | prescribed conveyance is carried out from a rolling mill, preventing the product bending by making one end side of the shape steel 52 contact | abut to the bottom side part of the groove part 51 by dead weight in each groove part 51. The shaped steel 52 carried in the cycle can be transferred and cooled sequentially from the first groove, for example.
[0004]
[Problems to be solved by the invention]
However, as shown in FIG. 12, in the configuration in which one end side of the shape steel 52 is brought into contact with the bottom side portion of the groove portion 51 as in the conventional case, the both side widths larger than the slope length L of the groove portion 51 are shown in FIG. 12. When the S shaped steel 52 is to be transferred, the side surfaces of the long and flexible shaped steel 52 come into contact with the top side of the groove 51, so that all or a part of the shaped steel 52 is shown as indicated by a two-dot chain line in the figure. May be caught on the top side of the groove 51. In this case, one end side of the shaped steel 52 may or may not come into contact with the bottom side of the groove portion 51, so that the product bending that has been exhibited by this contact becomes insufficient and the groove portion 51 is prevented. Since the position of the shape steel 52 becomes unstable, transfer by moving rake may fail.
[0005]
Therefore, usually, as shown in FIG. 11, by setting the slope length L to be larger than the maximum width S on both ends, a method of reliably placing the steel bars 52 of all sizes on the inclined surface 51a is employed. However, this method has the following problems.
[0006]
In other words, when the size (width S of both ends) of the shape steel 52 is reduced, the conveyance cycle is shortened. However, since the cooling bed transferred in synchronization with the transfer cycle increases the apparent transfer speed of the section steel 52 in proportion to the decrease in size, the slope length L corresponding to the maximum size is set. If it is made, the cooling time with respect to the small-sized structural steel 52 will become short. Therefore, in order to ensure sufficient cooling time, it is necessary to increase the number of the grooves 51 to increase the conveyance length or to increase the conveyance cycle. There is a problem of lowering.
[0007]
Therefore, the present invention can prevent product bending and transfer failure even when the slope length L corresponding to the short side width S is set so as to realize downsizing of the apparatus and improvement of productivity. It is intended to provide a cooling floor for rolling equipment.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is arranged in parallel at equal intervals from the cooling start end to the cooling end end in the width direction of the shape steel, and a plurality of groove portions for placing the shape steel while positioning with the inclined surface. , A moving rake means for transferring the shape steel of each groove portion to the adjacent groove portion at a constant pitch, and provided so as to be able to appear and retract along the inclined surface at the front end of the correction floor, and by contacting the shape steel, the shape steel The one end side and the other end side of the shape steel are supported by the inclined surfaces of the one or two grooves based on the stopper means for positioning the shape steel, and the widths of both ends of the shape steel and the slope length of the inclined surface. As described above, it is characterized by having control means for controlling the movement of the stopper means and the transfer of the moving rake means.
[0009]
According to the above configuration, the side surface and one end side of the shape steel are brought into contact with the top and bottom sides of the groove portion while supporting the one end side and the other end side of the shape steel with the inclined surface of one or two groove portions. Therefore, the positioning of the shape steel in the groove can be ensured. Therefore, even when the slope length of the inclined surface is set corresponding to the shape steel of the smallest size whose both side widths are the narrowest, the shape steel of various sizes can be accurately positioned in each groove portion. It is possible to reliably transfer the shape steel and to prevent the bending of the product. And if the slope length of the inclined surface can be set corresponding to the shape steel of the smallest size that has the shortest transfer cycle in this way, the shape steel of various sizes can be cooled most efficiently, so that In addition, the distance from the cooling start end to the cooling end end where the inclined groove portions are arranged in parallel can be shortened, and thus the apparatus can be miniaturized.
[0010]
Further, the control means supports the one end side and the other end side of the shape steel with the inclined surfaces of the two adjacent groove portions if the widths of both ends of the shape steel are equal to or greater than the slope length of the inclined surface. The stopper means is moved up and down, and the transfer by the moving rake means is performed twice for one conveyance cycle of the shape steel. On the other hand, if the width of both ends of the shape steel is less than the slope length of the inclined surface, The stopper means is moved forward and backward so as to support both ends of the shape steel by the inclined surface of the groove portion, and the transfer by the moving rake means is performed once for one conveyance cycle of the shape steel.
[0011]
As a result, the most efficient operation is to make the side or one end of the shape steel contact the top or bottom of the groove while supporting one or the other end of the shape steel with the inclined surface of one or two grooves. Can be done well.

The lifter table 23 is raised and lowered within the range up to.
[0017]
In addition, a stopper member 15 for positioning the angle steel 1 moving on the upper surface 14a at an arbitrary position is movable forward and backward in the gap between the inclined surface 4a on the front end side of the correction floor 2 and the upper surface 14a of the correction floor front end portion 14.

Moreover, since the stopper member 15 moves along the upper surface 14a of the correction | amendment floor front-end | tip part 14, it can adjust to an optimal position with the size of a shape steel.
[0018]
In the above configuration, the operation of the cooling bed will be described.
First, when the product data of the angle steel 1 to be cooled is input to the control device (not shown) by the operator, the control device stops the stopper member 15 based on the width S of both ends of the angle steel 1 in the product data. Find the position. Then, a control signal is output to the stopper drive mechanism 16 so as to be in the stop position, and the stopper member 15 is moved forward and backward by the stopper drive mechanism 16, thereby positioning the tip of the stopper member 15 at the stop position. In addition, as shown in FIG. 8, if the both-ends side width S of the angle steel 1 is wider than the slope length L of the groove part 4, as shown in FIG. The tip of the stopper member 15 is set at a position protruding from the bottom of the first groove (correction floor tip 14) of the correction floor 2 so as to be placed on each of the inclined surfaces 4a and 4a. On the other hand, as shown in FIG. 10, when the both-ends side width S of the angle steel 1 is narrower than the slope length L of the groove part 4, the stopper member is set so that the both ends of the angle steel 1 rest on one inclined surface 4a. The tip of 15 is set so as to coincide with or retract from the bottom of the first groove (correction floor tip 14) of the correction floor 2.
[0019]
Next, when the angle steel 1 corresponding to the above-mentioned product data is formed in a rolling mill (not shown), the run-in roller 30 is rotated in the arrow direction B as shown in FIG. While supporting the angle steel 1, it is carried into the front part (left side in the figure) of the correction floor 2. At this time, as shown in FIG. 4, since the shaft center of the run-in roller 30 is inclined, the angle steel 1 that is carried in while being supported by the roller surface 30 a is in the middle of the carry-in or after the carry-in is finished. It moves to a direction and it positions by one end side contact | abutting the side surface of the correction floor front-end | tip part 14. FIG.
[0020]
Thereafter, as shown in FIG. 5, the angle iron 1 is lifted by the upper surface 23 a of the lifter table 23 by raising the lifter table 23 along the side surface of the correction floor tip 14. Then, the angle iron 1 is moved from the lifter table 23 to the correction floor tip 14 by stopping at a position slightly above the upper surface 14 a of the correction floor tip 14. Thereby, as shown in FIG. 6, the angle steel 1 that has moved to the correction floor tip 14 moves while sliding on the upper surface 14 a, and one end side of the angle steel 1 abuts against the tip of the stopper member 15 in advance. It is positioned at the determined stop position.
[0021]
Next, as shown in FIG. 7, the moving rake 6 is circularly moved. As a result, when the moving rake 6 is raised, the first action of lifting the angle steel 1 from the first groove (correcting floor tip 14) of the correction floor 2 by the groove 7 of the moving rake 6 and the movement rake 6 in the right direction in the figure. The second operation of moving the angle steel 1 above the second groove of the correction floor 2 adjacent to the first groove when moving, and the angle steel 1 is placed in the second groove of the correction floor 2 when the moving lake 6 is lowered. The third operation and the fourth operation of returning to the original position when the moving rake 6 moves in the left direction in the figure are performed. And by performing such a series of operations from the first operation to the fourth operation in each groove, the angle steel 1 of each groove is transferred to the adjacent groove.
[0022]
In addition, the control device determines whether or not both end side widths S of the angle steel 1 to be cooled are wider than the slope length L of the inclined surface 4a, and as shown in FIG. If it is wider than the length L, the moving rake 6 is continuously rotated twice for one conveyance cycle of the angle steel 1, while as shown in FIG. It is determined that the moving rake 6 is rotated once for one conveyance cycle of one.
[0023]
Therefore, as shown in FIGS. 7 and 8, when the both end side width S is wider than the slope length L, the moving rake 6 is continuously rotated twice so that, for example, the angle steel 1 in the first groove is formed. After being transferred to the second groove, the angle steel 1 is transferred from the second groove to the third groove. And the angle steel 1 transferred to the 3rd groove | channel is each supported by the inclined surface 4a * 4a of the 2nd groove | channel and 3rd groove | channel where the one end side and other end side of the angle steel 1 adjoin, respectively, and a side surface is 3rd. Abuts on top of groove. As a result, the angle steel 1 is supported in the inclined surfaces 4a and 4a of two grooves (second groove and third groove) whose one end side and the other end side are adjacent to each other while the side surfaces are in contact with the top portion. Since correction is made, product bending is reliably prevented and the position of the angle steel 1 in each groove is stabilized, so that the product is reliably transferred by the moving rake 6.
[0024]
On the other hand, as shown in FIGS. 9 and 10, when both side widths S are narrower than the slope length L, the moving rake 6 is rotated once so that, for example, the angle steel 1 of the first groove is the second groove. To be transferred. And the angle steel 1 transferred to the 2nd groove | channel is stopped when the both ends of the angle steel 1 are supported by the inclined surface 4a of a 2nd groove | channel, and one end side contact | abuts to a bottom part. Thereby, since the angle steel 1 is corrected in a state in which one end side is in contact with the bottom portion while the one end side is supported by the inclined surface 4a of the second groove, the product bending is reliably prevented, Since the position of the angle steel 1 in the groove is stable, it is reliably transferred by the moving rake 6.
[0025]
As described above, as shown in FIG. 1, the cooling bed of the present embodiment is arranged in parallel at equal intervals from the cooling start end to the cooling end end in the width direction of the angle steel 1 (section steel). Moving rake means (moving rake 6) for transferring a plurality of groove portions 4 and 5 to be placed while being positioned by the inclined surfaces 4a and 5a, and the angle steel 1 of each groove portion 4 and 5 to the adjacent groove portions 4 and 5 at a constant pitch. ), And a stopper means (stopper member 15, stopper drive) which is provided so as to be able to protrude and retract along the inclined surfaces 4 a and 5 a in the groove portions 4 and 5 at the cooling start end and positions the angle steel 1 by contacting the angle steel 1. On the basis of the mechanism 16), the width S of both ends of the angle steel 1 and the slope length L of the inclined surfaces 4a and 5a, the inclined surface 4a of one or two grooves on one end side and the other end side of the angle steel 1・ Advancing and retracting the stopper member 15 so that it is supported by 5a Is the configuration in which a control device for controlling the transfer of kinetic Lake 6.
[0026]
More specifically, the control device described above includes the inclined surfaces 4a and 5a of the two adjacent grooves 4 and 5 if the width L of the both ends of the angle steel 1 is equal to or greater than the inclined surface length L of the inclined surfaces 4a and 5a. The stopper member 15 is moved forward and backward so as to support one end side and the other end side of the angle steel 1, and the transfer by the moving rake 6 is performed twice in succession for one conveyance cycle of the angle steel 1, while the angle steel 1 If the width L of the both ends is less than the slope length L of the inclined surfaces 4a and 5a, the stopper member 15 is moved forward and backward so that the inclined surfaces 4a and 5a of one groove 4 and 5 support the both ends of the angle steel 1 The transfer by the moving rake 6 is configured to be performed once for one conveyance cycle of the angle steel 1.
[0027]
According to said structure, when both-ends side width S of the angle steel 1 is more than the slope length L of the inclined surfaces 4a and 5a of the groove parts 4 and 5, the inclined surface 4a of two adjacent groove parts 4 and 5 *. Since the one end side and the other end side of the angle steel 1 are respectively supported by 5a, the angle steel 1 is positioned by the abutment of the top sides of the grooves 4 and 5 on the side surfaces of the angle steel 1. . On the other hand, when the width S of the both ends of the angle steel 1 is less than the slope length L of the inclined surfaces 4a and 5a, the both ends of the angle steel 1 are supported by the inclined surfaces 4a and 5a of one groove 4 and 5a. Therefore, the angle steel 1 is positioned when the bottom side of the grooves 4 and 5 comes into contact with one end of the angle steel 1.
[0028]
As a result, even when the slope length L of the inclined surfaces 4a and 5a is set corresponding to the minimum size angle steel 1 having the narrowest side width S, the angle steel 1 of various sizes is accurately placed in the grooves 4 and 5. Since the positioning can be performed, it is possible to reliably transfer the angle steel 1 by the moving lake 6 and to prevent the bending of the product. And if the slope length L of inclined surface 4a * 5a can be set corresponding to the minimum size angle steel 1 in which a conveyance cycle becomes the shortest in this way, the angle steel 1 of various sizes will be cooled most efficiently. Therefore, the productivity can be improved and the distance from the cooling start end to the cooling end end where the grooves 4 and 5 of the inclined surfaces 4a and 5a are arranged in parallel can be shortened, so that the apparatus can be made compact. Can be
[0029]
In addition, in this embodiment, although demonstrated using the angle steel 1 which is a kind of shape steel, it is not limited to this, It can apply to the shape steel which has another cross-sectional shape. . In this embodiment, the stopper cylinder 22 is used as the stopper drive mechanism 16 for moving the stopper member 15 forward and backward. However, the present invention is not limited to this, and various drive devices such as a motor can be used. it can.
In addition, since the stopper driving mechanism is exposed to a high temperature, it is desirable that the stopper driving mechanism has a structure (not shown) that absorbs the elongation of the member and the like because the position of the angle steel 1 can be more stabilized.
[0030]

A moving rake means for transferring to an adjacent groove portion at a constant pitch, a stopper means that is provided so as to be able to project and retract on an inclined surface at the front end of the correction floor, and that positions the shape steel by contacting the shape steel, and the shape steel Based on the widths of both sides of the slope and the slope length of the sloped surface, the stopper means protrudes and descends so that one end side and the other end side of the shaped steel are supported by the sloped surface of the one or two groove portions. Control means for controlling the transfer of the moving rake means.
[0031]
According to the above configuration, the side surface and one end side of the shape steel are brought into contact with the top and bottom sides of the groove portion while supporting the one end side and the other end side of the shape steel with the inclined surface of one or two groove portions. Therefore, the positioning of the shape steel in the groove can be ensured. Therefore, even when the slope length of the inclined surface is set corresponding to the shape steel of the smallest size whose both side widths are the narrowest, the shape steel of various sizes can be accurately positioned in each groove portion. It is possible to reliably transfer the shape steel and to prevent the bending of the product. And if the slope length of the inclined surface can be set corresponding to the shape steel of the smallest size that has the shortest transfer cycle in this way, the shape steel of various sizes can be cooled most efficiently, so that In addition, the distance from the cooling start end to the cooling end end where the inclined groove portions are arranged in parallel can be shortened, so that the apparatus can be reduced in size.
[0032]
Moreover, the said control means will each support the one end side and other end side of a shape steel with the inclined surface of two adjacent groove parts, if the both-ends side width of the said shape steel is more than the slope length of the said inclined surface, As described above, the stopper means is caused to appear and disappear, and the transfer by the moving rake means is performed twice continuously in one conveyance cycle of the shape steel, while the width of both ends of the shape steel is less than the slope length of the inclined surface. For example, the stopper means is projected and retracted so as to support both ends of the shape steel with the inclined surfaces of one groove, and the transfer by the moving rake means is performed once for one conveyance cycle of the shape steel.
[0033]
As a result, the most efficient operation is to make the side or one end of the shape steel contact the top or bottom of the groove while supporting one or the other end of the shape steel with the inclined surface of one or two grooves. There is an effect that it can be performed well.
