Description

[Detailed description of the invention] The present invention relates to a cutting and separating device for slab crops in continuous casting equipment.The purpose of the invention is to easily separate the parts of the slab connected to the dummy bar that do not become products, that is, the parts of the slab connected to the dummy bar. The object of the present invention is to provide a device capable of cutting and separating the parts.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a dummy bar; 2 is a slab that is pulled out by the dummy bar 1 and moves on the casting line 3 in the direction of the arrow; Without the downward protrusion 5, the dummy bar head 1a and the slab crop 2a cast into the head 1a can be separated only in the vertical direction.

6 is a slab crop cutting and separating device, and this device 6
consists of a cart 8 which is disposed above the casting line 3 and is movable on rails I arranged on both sides of the line 3, a cutting device main body 9 placed on the cart 8, and the main body. It consists of a slab cutting device 10 disposed on the front side of the slab cutting device 9, and a slab crop pushing device 11 disposed in front of the device 10.

The slab cutting device 10 is rotatably disposed between frames 12 protruding from the front surface of the cutting and separating device main body 6, and is rotated forward and backward by a prime mover (not shown).
A screw shaft 13 in which threaded portions with opposite screw rotation directions are formed on the right button and left portions 13a and 13b from the center thereof.
, a pair of female screw members 14 that are buttoned at positions equidistant from the center on the screw shaft 13 and screwed into the screw shaft 13, a torch header 15 fixed to the female screw members 14, and the cutting device main body. Arm 1 protruding from the lower front of 9
A guide bar 17 disposed between the guide bars 17, a pair of torch header supporting sliders 18 slidably disposed on the bar 17, and a connecting rod 20 connecting each slider 18 and the torch 19. Consisting of

The slab crop push-down device 11 includes a guide bar 22 disposed between support frames 21 protruding from the front surface of the cart 8, and a piston stem 23a that is suspended from the bar 22 so as to be slidable in the horizontal direction. a pair of cylinder devices 23 that can freely protrude downward; and a U-shaped cylinder device that is disposed on the front surfaces of both the sliders 18 so as to be movable in the vertical direction and whose tip portion protrudes from the upper housing of the guide bar 22. The distal end of the clamp arm 24 is formed into a bifurcated shape, and the interval between the bifurcated portions is slightly wider than the width of the upper end 25 of the cylinder device 23. .

26 is a crop chute, and 21 is a disc roll that constitutes the casting line 3.

Next, a method for cutting and separating the slab crop 2a based on the above configuration will be explained.

That is, the cart 8 is run at the same speed as the slab 2 which is pulled out by the dummy bar 1 and moves on the casting line 3,
The torch 19 supported by the cart 8 is placed in a position where the slab crop 2a is to be cut.

Next, in this state, the screw shaft 13 is rotated in one direction, and the two torches 19, which are separated by sandwiching the slab 2, are brought closer to the center along the direction transverse to the casting line 3. The slab crop 2a cast into the dummy bar head 1a is cut by melting with an arc.

Next, from this state, the screw shafts 13 are reversed to move the torches 19 away from each other, and the clamp arm 24 is brought above the cylinder device 23 in the standby position outside the casting line 3, as shown by the imaginary line in FIG. The clamp arm 24 is lowered into an air cylinder device (not shown) in the slider 18, and the upper end 2 of the cylinder device 23 is
5 to fit the clamp arm 24.

In this state, the screw shaft 13 is rotated in the normal direction again, and the third
As shown in the figure, both torches 19 are brought to the center, thereby bringing the cylinder device 23 above the slab crop 2a.

Next, the clamp arm 24 is raised and the arm 24 is
and the cylinder device upper end 25 is released, the piston stem 23a of the cylinder device 23 is extended downward to press the slab crop 2a downward, and the slab crop 2a is separated from the dummy bar head 1a. and push it down.

The above-mentioned slab cutting device 10 is used not only for cutting the slab slop 2a but also for cutting the slab 2 itself to a fixed length.

Further, in the above embodiment, the cylinder device 23 is movable in the horizontal direction, but the cylinder device 23 is not limited to this, and may be fixed to the slab cutting device 10.

As is clear from the above, the slab cutting and separating device installed in the continuous casting equipment of the present invention is arranged above the casting line and runs at the same speed as the slab moving on the line. Since the flexible slab cutting device is provided with a means for pushing down the slab crop that can freely protrude downward, the shape of the dummy bar head can be changed so that the head and the slab crop cast into this head are only vertically aligned with each other. If it is formed so that it can be separated, the slab crop of the slab pulled out by the dummy bar is cut by the cutting device, and then the slab crop can be easily removed from the dummy bar head by simply pressing it downward by the push-down means. It can be peeled off and separated.
