Description

[Detailed explanation of the idea] The present invention relates to a mold device in continuous casting equipment.

Some continuous casting equipment is configured so that a support roll part is lifted up through an opening formed in the center of a vibrating table that supports a mold framework.

In this case, the opening is made large so that the support roll can easily pass through, but if the mold framework is to be placed directly over the vibrating table, the span of the mold framework must be made large.

However, if this is done, the strength of the mold framework must necessarily be increased, resulting in a large weight, which is economically disadvantageous.

Therefore, the present invention provides a molding device that does not require a long mold framework.

An embodiment of the present invention will be described below with reference to the drawings.

This embodiment is related to continuous casting equipment in which the slab conveyance path consists of a circular arc section and a horizontal section. 1a, lb and short side 1c.

1d, and has a large opening 2 in the center.

Reference numeral 3 designates a pair of jacket beams extending between the opposing ends of the long sides 1a and lb, each of which has a cooling water flow passage (not shown) inside.

Reference numeral 4 denotes a mold framework consisting of cooling boxes 6, 7 for the long mold pieces 5 and cooling boxes 9 for the short sides 8 of the mold.

Of the two mold long piece cooling boxes 6 and 7, the cooling box 6 on the rear edge side, that is, on the rear side in the slab conveying direction A, has a main body 6a parallel to the long sides 1a and lb, and both ends of the main body 6a. The arm portion 6b extends from the short side portions 1c and ld along the short side portions 1c and ld.
It has a U-shaped planar shape.

The cooling box 7 on the front edge side has grooves formed on both end faces thereof, which fit into keys 10 protruding from the inner surface of the arm portion 6b, and are movable back and forth in the directions of arrows C and D.

11 is a threaded rod passing through the squares of both mold long piece cooling boxes 6 and 7; 12 is a nut screwed onto the threaded rod 11;
The mold long piece cooling boxes 6, 7 and the mold short piece cooling boxes 9.9 are firmly tightened by these two pieces 11.12, and the mold framework 4 is constructed.

A recess 13 is formed in the center of the upper surface of both the jacket beams 3, and the arm portion 6b is fitted into each of the recesses 13.

14 a slide base fixed to the bottom surface of both the recesses 13; 15 a slider fixed to the lower surface of the arm portion 6b and slidably mounted on the slide base 14; is movable in the directions of arrows C and D.

16 is a bolt/nut for fixing the arm portion 6b to the jacket beam 3; 17 is a port portion formed at the rear edge side end of the jacket beam 3; Water supply and drainage ports 1 for cooling boxes 6 and 7
8, and the jacket beam 3 is connected from the water supply port 18.
Inside the mold long piece cooling box 6 through the expansion joint 19
．． 7, and the used cooling water is supplied to the cooling boxes 6, 7, the expansion pipe joint 19, and the jacket beam 3.
Water is drained from the discharge port 18 through the inside.

Similarly, both port portions 17 are provided with water supply and drainage ports 20 for the mold short piece cooling box 9.

21 is a flexible pipe for supplying cooling water to the mold short piece cooling box 9; 22 is a protrusion protruding from both sides of the port section 17; 23 is a flexible pipe that connects the protrusion 22 to the vibration table 1;
Bolts and nuts 24 fix the front end of the jacket beam 3 to the long side 1a of the vibration table 1.
Bolts and nuts 25 are fixed to the arm portion 6b.
This is a width adjustment device for slabs whose main body is supported by.

In the above configuration, when lifting the support roller part (not shown) under the vibration table 1, remove the bolts and nuts 23 and 24 fixing the jacket beam 3, and lift the support roller part (not shown) under the vibration table 1 through the opening 2 of the table 1. Then, a wire rope taken down from a crane or the like is tied to the support roller portion, and then this rope is wound up to lift the support roller portion together with the jacket beam 3 and the mold framework 4.

Alternatively, after lifting the jacket beam 3 and the mold framework 4 to open the opening 2 of the vibration table 1, the support roller section may be lifted and removed.

Further, according to the configuration of this embodiment, the port portion 1 having the water supply and drainage ports 18 and 20 at the end on the trailing edge side of the jacket beam 3
7, the cooling water can be centrally controlled from the trailing edge side, and by using the inside of the jacket beam 3 as a cooling water passage, the number of piping to the cooling boxes 6, 7, and 9 can be reduced. At the same time, the jacket beam 3 itself can also be cooled.

In addition, operations such as changing the thickness and width can be concentrated on the trailing edge side, resulting in good work efficiency.

As described above, according to the mold device of the continuous casting equipment of the present invention, a pair of beams are passed between the mutually opposing ends of the same long side of the vibrating table, and the mold framework is placed on the beams. Because of this, the span of the mold framework can be made significantly smaller than when the mold framework is passed directly over the vibration table, which eliminates the need to increase the strength of the mold framework and makes it possible to reduce the weight of the mold framework. can.

Furthermore, there is no need for a vibrating frame that covers the opening of the vibrating table as in the prior art.
