Description

[Detailed Description of the Invention] This invention relates to a taper adjustment device for the short side of a mold in a continuous casting machine.

In a continuous casting machine, molten steel is supplied to a mold by a tongue pusher, is cooled in the mold, and then drawn out as a slab toward a roller apron below.

In a mold with a rectangular cross section, the short side of the mold has a taper amount that adapts to the various conditions such as the width of the slab, the type of steel to be cast, and the casting speed in order to stably draw the slab. It becomes necessary.

For this reason, conventional equipment requires a dedicated adjustment piece with a predetermined taper amount in accordance with each operating condition, and it is inconvenient that it takes a lot of time and effort to replace it.

The present invention was made to improve this problem, and solves the conventional problem by providing a taper adjustment piece that can be adjusted with a bolt between the short side of the mold and the mold frame that holds the short side. This is what I did.

The following will explain the embodiments shown in the drawings.

Reference numeral 1 denotes a mold frame on which a piece receiving seat 2 is provided.

4 is a taper adjustment piece for adjusting the taper of the short side 3 of the mold, and includes a piece frame 5 and the piece frame 5.
, a wedge 8 for horizontally moving the upper liner 6, and an adjustment bolt 9 for moving the wedge 8 vertically.

Reference numeral 10 denotes a cylinder attached to the mold frame 1, the moving end of which is pinned to the short side 3, and the taper adjustment piece 4 is moved to the piece receiving seat 2 by outward pulling pressure. The pressing is fixed.

Since the present invention is configured as described above, in order to reduce the inclination of the short side 3 of the mold, the adjustment bolt 9 screwed onto the piece frame 5 can be rotated to push the wedge 8 upward.

That is, the upper liner 6 is pushed out in the horizontal direction by the movement of the wedge 8, pushing the upper part of the short side 3 inward, thereby reducing the inclination of the short side 3.

Furthermore, when increasing the inclination, the inclination of the short side 3 can be increased by performing the opposite operation as described above.

In addition, in this embodiment, an explanation has been given of a case in which an adjustment mechanism is provided only in the upper part of the piece frame 5, but if the lower part of the piece frame 5 is made to have the same structure as the upper part, it is possible to change the lower dimension of the short side. Become.

As detailed above, the present invention provides a taper adjustment device for the short side of the mold that has a simple structure, is easy to operate, and allows stepless adjustment by providing a taper adjustment piece between the mold frame and the short side. The obtained results are highly effective in contributing to improving production efficiency in continuous casting machines.
