Description

[Detailed description of the invention] The present invention relates to a segment device in continuous casting equipment.
The purpose is to be able to easily adjust the distance between the upper and lower rolls supported by the upper and lower frames of the segment with a simple configuration, and to reliably maintain the adjusted distance between the rolls. The goal is to provide a device that can do this.

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

1.2 is the upper and lower frames of the segment, 3 is the side frame 1
, four cylindrical columns arranged at the four corners between 2,
Each column 3 is welded to the upper surface of the lower frame 2.

Reference numeral 4 denotes a servo cylinder device movably installed inside each column 3, and a bracket 5 fixed to the end face of the cylinder body 4a of the device 4 fits into a recess 6 formed in the upper frame. It is rotatably fitted onto a horizontal pin 7 disposed in the recess 6 via a spherical sleeve 8.

A threaded portion 9 is formed at the free end of the piston rod 4b of the cylinder device 4, and the lower end portion of the arm 10, which is screwed into the threaded portion 9, fits into a recess 11 formed in the lower frame 2. and a horizontal pin 12 disposed in the recess 11.
The sleeve 13 is rotatably fitted to the outside through the sleeve 13.

Reference numeral 14 denotes a roll interval detector for detecting the interval α between the upper and lower rolls 16 and 17 rotatably supported by the frames 1 and 2 via bearings 15, respectively. The main body 14a has a cylindrical body 1 on the upper frame 1L surface.
8 and the sensing rod 14 of the detector 14
b is connected to a bracket 20 on the upper surface of each column 3 by a pin 21 via a connecting rod 19 passing through the upper frame 1.

Reference numeral 22 denotes a driving roll hydraulic cylinder, which in this embodiment is attached to the bearings 15 of the rightmost roll 16 and the center roll 16 among the rolls 16 supported by the upper frame 1.

Therefore, by this cylinder 22, both the rolls 16
is pressed against a dummy bar (not shown) or slab A, and both rolls 16 are rotated by a drive device (not shown), thereby transporting the dummy bar or slab A.

Reference numeral 23 denotes a water cooling jacket disposed on the side surface of each column 3 facing the slab A.

In the above configuration, when pressure oil is put into the piston rod extension side chamber 24 of the servo cylinder device 4 and pressure oil is removed from the piston rod contraction side chamber 25, the piston rod 4b is extended, the upper frame 1 is lifted, and the roll The interval α is widened.

On the other hand, if pressure oil is introduced into the contraction side chamber 25 and pressure oil is removed from the extension side chamber 24, the roll interval α is narrowed.

As the upper frame 1 moves up and down, the detector 1
The four sensing rods 14b are moved up and down via the connecting rods 19, whereby the roll distance α is detected by this detector 14.

Therefore, if the roll interval α predetermined by a casting machine or the like does not match the roll interval α detected by the detector 14, the servo cylinder device 4 is operated to increase or decrease the roll interval α, thereby increasing or decreasing the roll interval α. It is sufficient to set the interval α to an ideal value.

What is important here is especially the servo cylinder device 4.
This means that it uses

That is, as a characteristic of the servo cylinder device 4, the piston 4
Since C can be fixed at an appropriate position within the loaf S, if the oil pressure in the extension side chamber 25 and the contraction side chamber 25 is increased when the roll interval α reaches the ideal value as described above, The piston 4C does not move, the roll distance α is firmly maintained, and the roll distance α is not widened by the bulging force of the slab A.

As described above, according to the segment device of the continuous casting equipment of the present invention, a servo cylinder device is installed inside the cylindrical column disposed between the upper and lower frames, and the cylinder body of the cylinder device is connected to the one frame. In addition, it has a very simple configuration that only connects the screw I/rod of the cylinder device to the other frame, and furthermore, the roll interval can be easily adjusted by simply operating the servo cylinder device. At the same time, the adjusted roll spacing can be maintained reliably.

Further, since the column and the servo cylinder device oppose the force in the direction of drawing out the slab, there is no risk of the upper frame swinging.
