Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dollar changing device for continuous casting.

Regarding a ladle changing device for continuous casting using a single dollar cart, the present application was previously filed in Japanese Patent Application No. 1983-45288.
However, the latter device was found to have the following drawbacks.

(I) As shown in Figure 3 attached to the specification of Utility Model Application No. 54-17184, one self-propelled one-dollar dolly carrying a ladle is placed at position A (casting position of the continuous casting machine). Then move it to the fixed B position (empty dollar retreat wall position) at the other end of the horizontal frame of the continuous caster, and remove the empty dollar to the outside using a crane from above the self-propelled dollar cart. In this case, the self-propelled one-dollar dolly moves outside the crane's approach limit, and the empty dollar on the self-propelled one-dollar dolly cannot be removed by the crane, which may impede subsequent processes. It may be harmful.

(II) The time required to move a self-propelled one-dollar cart loaded with cast empty dollars from the casting position (A position) to the empty one-dollar retreat position (B position) is Although it is very desirable from the viewpoint of shortening the replacement time of a full ladle and improving the operational efficiency of the continuous casting machine,
As shown in the figure, a considerable amount of space is required to bring in a full new dollar from the upper side of the dollar cart at the casting position, so the distance between positions A and B is Can't get close.

As a result, it takes a long time to move the ladle cart, and the time required to replace the ladle cannot be shortened.

This proposal addresses the drawbacks (I) and (II) of the latter proposed device.
It was proposed with the aim of solving this problem, and consists of two self-propelled one-dollar carts that run on two parallel upper and lower tracks, and one of these two self-propelled ladle carts. The series is characterized by being equipped with an elevating mechanism for raising and lowering the ladle, and configured to be able to transfer one dollar from one self-propelled one-dollar dolly to the other self-propelled one-dollar dolly. This relates to a dollar exchange device for casting.

Hereinafter, the present invention will be specifically explained with reference to embodiments shown in FIGS. 1 to 3.

In those figures, 1 is a first self-propelled one dollar trolley;
2 is a single dollar, 3 is a tangent of the continuous casting machine, 4 is a horizontal frame of the continuous casting machine, and the first self-propelled single dollar trolley 1 reciprocates on the upper surface of the horizontal frame 4 along its longitudinal direction. It is possible to move.

(In order to facilitate and ensure the reciprocating movement of the first self-propelled dollar cart 1, a running rail for the first self-propelled dollar cart 1 is installed along the longitudinal direction of the horizontal frame 4. It is desirable to lay it.

) 7 is a second self-propelled one-dollar trolley 1 that is separate from the first self-propelled one-dollar trolley 1.
The second self-propelled one-dollar trolley, the second self-propelled one-dollar trolley 7
is a second self-propelled one-dollar trolley running frame 8, which is disposed below the horizontal frame 4 and parallel to the horizontal frame 4 as shown in the figure, so that the upper surface thereof can be reciprocated along its longitudinal direction. It has become.

(Note that it is desirable to lay the running rails of the second self-propelled one-dollar truck 7 on the upper surface of this running frame 8 as well.

) 6 is an elevating mechanism, such as a hydraulic cylinder, mounted on the second self-propelled ladle truck 7, which moves up and down while maintaining a horizontal position by expanding and contracting the rod of the hydraulic cylinder. It is self-propelled and installed on one-dollar trolley 7.
The upper surface of the same dollar support base 5 is at a height position (not shown) at which it receives and supports the first dollar 2 on the first self-propelled ladle cart 1 when the hydraulic cylinder 6 is at its maximum stroke. It is designed to be able to rise to

An embodiment of the device of the present invention is constructed as described above, and has a fully loaded ladle 2 on the first self-propelled ladle truck 1 at the casting position (position A) during operation of the continuous casting machine. As the casting process progresses, the molten metal inside the tundish 3 is poured into the tundish 3, and when it is emptied, the first self-propelled one dollar cart is emptied and moved to position B or C with the one dollar on it. move to a position or an intermediate position.

(In this case, the dollar support base 5 of the second self-propelled dollar cart 7 is located at the height shown in FIG. 1.

) Simultaneously with the movement of the first self-propelled ladle cart 1, the second self-propelled one-dollar cart 7 moves, and the first self-propelled one-dollar cart 1 moves to B.
When it moves to the position, it moves to the B position (the state shown in Fig. 1), and when it moves to the C position, it moves to the corresponding position (the state shown in Fig. 2) on the traveling frame 8, and the elevating mechanism 6 is operated in the upward direction to raise the ladle support base 5 to the upper limit position, and the empty ladle 2 on the first self-propelled ladle cart 1 is raised.
After being transferred onto the support base 5, the first self-propelled dollar cart 1 returns to its original position (position A).

(Refer to Figure 2) At the same time as this first self-propelled one dollar cart 1 returns to the casting position (position A), the full new one dollar truck 2' carried by the crane 9 is transferred to the first self-propelled one dollar cart 1. The molten metal is placed on the running one dollar cart 1, and pouring of molten metal from the full one dollar cart 2' into the container dish 3 continues.

On the other hand, the crane 9 carrying the dollar 2' onto the first self-propelled one-dollar truck 1 is moved to the second self-propelled one-dollar truck 7 at position B or C or between them. The empty dollar 2 on the dollar support stand 5 is removed to the outside.

(See Figure 3) Since the device of the present invention has the above-described configuration and operation, according to the present invention, the first self-propelled dollar cart 1 is at the casting position (position A). Then, as the continuous casting machine operates, the dollar is emptied one by one, and the dollar is transferred onto the second self-propelled dollar cart 7 located at the C position, B position, or any desired positioner caulking between them. Since the self-propelled ladle cart 1 returns to the casting position (A position) immediately after the ladle transfer, the self-propelled ladle cart 1 returns to its original position (
Since the device can be returned to position A), the time required for moving the first self-propelled one-dollar trolley 1 is shorter than that of the fixed one-dollar tray of the latter proposed device. In other words, not only can the time required for ladle replacement be shortened, but depending on the layout of the factory, the crane 9 can
There may be cases where the ladle does not move to the C position, but in that case, if the ladle is moved within the range where the crane 9 can move to the C position or its vicinity, there is no risk of any hindrance to the operation of the continuous casting machine. A practical effect can be obtained in that all the drawbacks of the above proposed device can be eliminated.

In addition, in the above embodiment, the lifting device 6, the ladle support 5
Both self-propelled one-dollar carts 1 and 7 are arranged so that the second self-propelled one-dollar cart 7 is located below the first one-dollar one-dollar cart 1. This relationship may be reversed, and instead of providing the lifting device 6 and the ladle support 5 on the second self-propelled ladle truck 7, they may be provided on the first self-propelled ladle truck 1.
