Description

[Detailed Description of the Invention] The present invention relates to a molten steel heat retention device in a ladle in continuous casting equipment, and its purpose is to prevent the temperature of molten steel in the ladle from decreasing.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a ladle support device in continuous casting equipment, which includes a swing support 3 fixed on a pedestal 2 by an anchor bolt (not shown), and a swing supported rotatably on the swing support 3 via a swing bearing 4. An arm 5, a swing drive device 6 for swinging the swing arm 5, that is, an electric motor 7, and a pinion 8.
and a turning gear 9. Openings 10 into which the ladle can be inserted are provided on both the left and right sides of the swing arm 5, and within each opening 10 is a jack 1 that raises and lowers the ladle and supports it via a pair of elevating frames 11.
Four pieces of 2 are provided. Note that these four jacks 12 can be raised and lowered simultaneously by a single electric motor (not shown). Reference numeral 13 denotes an in-ladle molten steel heat retention device provided on the ladle support device 1, which supports the ladle holding cover 14 so as to be rotatable and movable up and down. That is, 1
Reference numeral 5 denotes a swing support base fixed near one end of the central part of the swing arm 5; 16 is a swing post rotatably supported by the swing support base 15 via a swing bearing 17; 16a is provided protrudingly. Reference numeral 18 denotes a hanging beam whose middle part is pivotally supported in a vertical plane by a support bracket 19 erected on the upper surface of the arm part 16a, and the other end of the rear end is supported by the base part 16b of the swing post 16. It is connected to an electric cylinder 20 and can be raised and raised freely. Further, at one end of the distal end of the suspension beam 18, the heat insulation cover 14 is pivotally supported so as to be swingable in a vertical plane via a mounting bracket 21 erected on the upper surface thereof, and the suspension beam 18 is further elevated. In order to prevent the heat insulating cover 14 from swinging when the heat insulating cover 14 is moved, an auxiliary link 22 is attached parallel to the hanging beam 18 between the support bracket 19 and the mounting bracket 21 to form a parallel link mechanism. In addition, 23
2 is a swing drive device supported by a swing support base 15;
4 is a pinion attached to the output shaft of the swing drive device 23, and 25 is a swing gear meshing with the pinion 24 and attached to the lower end of the swing post 16. Therefore, by operating the swing drive device 23, the hanging beam 18 can be turned.

Next, the operation will be explained.

First, as shown in FIGS. 1 and 2, the ladle A is placed in the left opening 10a of the swing arm and raised by the jack 12. Next, the right opening 10 of the swing arm 5 is opened by the hanging beam 18.
b The heat retaining cover 14 supported above is moved onto the ladle A placed in the left opening 10a by operating the swing drive device 23 as indicated by the arrow a. Next, the swing arm 5 is moved to its swing drive device 6.
After turning 180 degrees as shown by arrow b,
Lower the ladle A. Then, as shown in FIG. 3, when the electric cylinder 20 is raised as shown by the arrow C, the hanging beam 18 is tilted downward, and the heat insulating cover 14 is lowered as shown by the arrow d and placed on the ladle. The upper opening of ladle A is closed to prevent the temperature of the molten steel in ladle A from dropping.

As described above, according to the heat retaining device of the present invention, the opening on the upper surface of the ladle can be easily and automatically sealed with the heat retaining cover, and therefore, it is possible to effectively prevent a drop in the temperature of molten steel in the ladle. can. Further, since the mounting bracket for attaching the heat retaining cover is always parallel to the support bracket, the heat retaining cover does not swing during operation.
