Abstract

PURPOSE:To enable arrangement of side blocks placed on a metallic beld under mutually while allowing the blocks to be adhesively with each other by supporting each side block with roller link pivotaly at ascending position while travelling on side block guide at the time of turning the metallic belt. CONSTITUTION:At the time of turning the metallic belt 10, the roller link 1 is travelled on the metallic belt 10, and the side block 2 is travelled on the side block guide 5 separately arranged to the metallic belt 10. That is, the side block 2 is set at the ascending position along a bracket 3 and travelled on the side block guide 5. Therefore, by arranging the side block guide 5 at outer part from travelling way of the metallic belt 10 by >=1/2 of height of a pin link 4, at the time of turning the side block 2n-1 and the side block 2n, these are not interfered with mutual contact, and further, at the time of placing the side weir on the metallic belt 10, the side blocks 2 can be brought into mutual contact without any trouble.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side weir used in a single-belt continuous casting machine. Figure 4 shows the patent application filed in 1888.
This is an explanatory diagram of the single-belt continuous casting machine described in No. 862.
A) is an explanatory side view, and (B) is an explanatory plan view. A metal belt 1 stretched between pulleys 19 (19') rotating in the direction of the arrow and running straight upward in an endless manner.
Side weirs 11 and 11' are placed on both sides of the belt 0 and run at a speed synchronized with the metal belt 10.

[0002] The side weir 11 (11') is formed by connecting a large number of side blocks 2 to a chain, and runs endlessly along the straight running of the metal belt 10. A rear weir 12 extends between the weirs 11 and 11' on both sides and is placed on the metal belt 10. Note that the rear weir 12 is a metal belt 10 or a side weir 11.
(11'), but is held at a predetermined position.

[0003] The molten metal 14 is passed through the metal belt 10 and the side weir 11 (1
The molten metal is injected into a pool 13 formed by the molten metal 1') and the rear weir 12, but since the back side of the metal belt 10 is cooled by the cooling device 16, the molten metal forms a solidified shell 15 on the metal belt 10. This solidified shell 15 is the metal belt 1
0 and travels in the direction of arrow 18 and is taken out as a thin plate 17.

2. Description of the Related Art In FIG. 4A, it is important that side blocks 2n-1 and 2n placed on a metal belt 10 are connected in close contact with each other. That is, since the side blocks form the side walls of the molten metal pool 13, if there is a gap in the connecting part of the side blocks, the molten metal will enter this gap and solidify to form a casting, making it difficult to take out the thin plate 17 from the continuous casting machine. becomes difficult and causes casting accidents.

FIG. 3 shows that the metal belt 10 is attached to the pulley 1 of FIG.
9 (19') is an explanatory diagram of a conventional side weir when rotating along the line 9 (19'). At this time, side blocks 2n-1, 2n, 2n
+1,... form a roller link and mutually pin link 4
It travels as a chain connected by n-1, 4n, 4n+1,... However, with this chain connection,
It is difficult to closely arrange the side blocks 2n-1, 2n, 2n+1, . . . on the metal belt 10 for the reasons described below.

In FIG. 3, a pin link 4n+1 connects side blocks 2n+1 and 2n placed on a straight-moving metal belt 10. In pin link 4n+1,
In order to bring the side blocks into close contact with each other, the distance L1 between the axes of the pin links (the distance between P1 and S1) must be set to P1 and Q.
This is twice the interval a of 1. That is, L1=2a is the condition for bringing the side blocks into close contact with each other. 2n-1 in FIG. 3 is a side block immediately before being placed on the metal belt 10 moving straight. At this time, since the distance L2 between P2 and S2 is the distance between the axes of the pin link 4n, L2=L1=2a. The distance between P2 and Q2 is a, and therefore the distance between P2 and r is greater than a. Further, the distance between S2 and r is also the same as a or larger than a. Therefore, in this case, P of L2=2a
P2-r, which is larger than a, and S2-r, which is the same as a or larger than a, are passed through the space between 2 and S2, but this passage is difficult. Therefore, in the chain connection shown in Figure 3, 2
n and 2n-1 contact and interfere at r and mesh, or L2 expands. Therefore, the metal belt 1 moving straight
When it reaches the position where it is placed on the side block 2
It is not possible to arrange n and 2n-1 in close contact with each other.

[0007]

As described above, in the conventional side weir, it is difficult to arrange the side blocks placed on the straight-moving metal belt 10 in close contact with each other. The present invention was made to solve this problem, and in a side weir in which a large number of side blocks are connected by a chain, the side blocks placed on the metal belt 10 moving straight can be brought into close contact with each other without any force. This provides a side weir that can be installed.

[0008]

Means for Solving the Problems and Operations FIG. 1 is an explanatory diagram of a side weir according to the present invention. Each roller link 1 of the chain of the present invention has a bracket 3 through which a side block 2 is inserted, and is interconnected by a pin link 4. Each side block 2 is provided with a bracket insertion hole, and the roller link 1 is inserted into the bracket insertion hole to insert the bracket 3 into the bracket insertion hole.
Fit into. Note that the side block 2 is fitted to be movable up and down along the bracket 3. Also, when each side block is placed on the metal belt 10 that moves straight,
As shown in FIG. 1(A), they are formed into rectangular shapes that are arranged in close contact with each other. FIG. 1(B) is an explanatory diagram of the E--A cross section of FIG.
It is a figure placed on 0. That is, when placed on the metal belt 10 moving straight, each side block 2 is arranged at a position lowered along the bracket 3.

As already mentioned with reference to FIG. 4, before or after the side weir 11 is placed on the metal belt 10 moving straight,
Rotates endlessly. During this rotation, the side weir of the present invention:
For example, the roller link 1 runs on a metal belt 10, and the side block 2 runs on a side block guide 5 provided separately from the metal belt 10. FIG. 1(C) is an explanatory diagram of the roller link 1 and the side block 2 at this time. The side block 2 is arranged at an elevated position along the bracket 3 and runs on the side block guide 5.

FIG. 2A is a diagram showing an example of a side block guide. For example, the side block guide 5, which has a diameter larger than the running path of the metal belt 10 and has an arcuate surface concentric with the running path of the metal belt, is moved further one time after the end portion T has finished rotating.
They are arranged so as to extend parallel to the metal belt 10 by more than the pitch. As seen in FIG. 2(A), side block 2n-
1 and 2n are placed in an elevated position and rotated because they run on the side block guide 5. For example, if the side block guide 5 is provided outside the running path of the metal belt 10 by more than 1/2 of the height of the pin link 4, the side blocks 2n-1 and 2n will not come into contact with each other during rotation. do not have. When the chain runs, side block 2n moves to 2
The position n+1 is reached, but during this movement, for example, the top surface of the side block is pushed down by the push-down guide 6 toward the arrow 7.
Push down in the direction. By this pushing down, the side block 2 changes from the raised state of FIG. 1(C) to the lowered state of FIG. 1(B), and the side blocks 2n+2 and 2 of FIG. 2(A)
N+1 is placed on and connected to the metal belt 10 moving straight, but 2n+2 and 2n+1 are closely connected to each other to form a side dam with no gaps.

FIG. 2A shows an example in which the roller link 1 runs on the metal belt 10 when it rotates, but the roller link rotates along a different running path than the metal belt 10. It may be something. Figure 2 (B
) is a diagram showing this example, in which the side weir 11 runs along the running path 9 on the outside of the metal belt 10. At this time, the roller link rotates on the running path 9. In addition, the side block 2 has a side block guide 5 provided separately from the running path 9 of the roller link.
-1. It is clear from the above description that even in the case of FIG. 2(B), the side blocks 2 can be arranged in close contact with each other without any difficulty on the metal belt 10 moving straight.

Although the present invention has been described with reference to FIGS. 1 and 2, the present invention includes a side block having a shape different from that shown in the figures
Similar effects can be achieved in the case of roller links, pin links, and side block guides. Therefore, other side weirs (not shown) having the configuration of the present invention are also included within the scope of the present invention.

[0013]

As is clear from the above explanation, when the side weir of the present invention is used, the side blocks do not come into contact with each other and interfere with each other when the side weir rotates, and the side weir does not touch or interfere with each other when the side weir rotates. When placed, the side blocks can be placed in close contact with each other without any difficulty. For this reason, when the side dam of the present invention is used, it is possible to prevent the occurrence of casting at the joint between the side blocks and casting accidents caused by the occurrence of casting.
