The present invention relates to a device for determining the vertical and horizontal position of the casting bow when the casting bow of the continuous casting machine is coupled to a pinch roll and a straightening device. Specifically, the present invention relates to a casting bow positioning gauge of a continuous casting machine, which is capable of improving work productivity and quality of finished products by quickly and accurately determining a horizontal and vertical position of a casting bow regardless of a pinch roll.

The positioning gauge of the casting bow according to the prior art consists of an egg plate (R-Plate) 100 having a lower curvature as shown in FIG. In the vertical positioning of the casting bow, the egg plate 100 processes the lower curvature surface 100a to match the curvature R 10.000 formed by the continuous casting machine, so that the curvature surface 100a is the casting bow 110. ) Rolls 49a (110a) and pinch rolls 120 and 120a and 120b of the pinch roll 120 and the first roll (130a) of the straightening device (130), The lower curvature surface (100a) was confirmed that the roll does not contact, and the gap was measured as the gap gauge 140 to determine the high and low of the casting bow (110). However, prior to the positioning operation of the casting bow 110, the first and second rolls 120a and 120b of the pinch roll 120 are positioned at 0 to 0.3 m / m high at R 10.000 curvature to draw the slabs. (See FIG. 4), the first and second rolls 120a and 120b of the pinch roll 120 should be in contact with the lower curvature surface 100a of the Al plate 100, but the casting bow ( When the 110 is high, since the lower curvature surface 100a first contacts the 49th roll 110a of the casting bow 110, the first and second rolls 120a and 120b of the pinch roll 120 do not touch. The exact vertical height of each roll cannot be determined. Then, when the positioning in the vertical direction as described above is finished, the piano wire 160 is installed on the 48th roll 110b of the casting bow 110 and the 1st roll 130a of the straight line retainer 130 to measure the tape. ), The distance was measured, and the horizontal position was determined after comparing with the reference value (1.098 + 20, -0). In addition, when the positioning in the vertical and horizontal directions as described above is completed, the casting bow 110 is lifted by the hydraulic jack 180 illustrated in FIG. 4, and then the liner (in the liner adjusting unit 190) is formed. 190a) was adjusted, and such measurement and adjustment were repeated until the vertical and horizontal positions of the casting bow 110 were correct.

However, in the conventional method, the 49th roll of the casting bow 110 is interrupted by the pinch roll 120 protruding upward from 0 to 0.3 m / m when positioning in the vertical direction using the egg plate 100. It is difficult to accurately measure the position (110a) and the first roll (130a) of the straight line holding device 130, due to the measurement is not accurate due to shaking, etc. when positioning in the horizontal direction using a tape measure 170 and the piano wire 160 By affecting the vertical positioning, accurate positioning of the liner 190a is not performed, and thus, work productivity is reduced due to unnecessary repetitive work, and the cause of deterioration of the finished slab quality due to the inability to accurately position the casting bow is caused. It was to occur.

The present invention is to solve the conventional problems as described above, when the casting bow is coupled to the pinch roll and the linear holding device, the horizontal and vertical positioning of the casting bow is executed accurately and quickly to greatly increase the maintenance work productivity The aim is to provide a casting bow positioning gauge for continuous casting machines that is improved to improve and produce high quality slab finished products.

In order to achieve the above object, the present invention, in the case of coupling the casting bow of the continuous casting machine to the pinch roll and the linear holding device, in the device for determining the horizontal and vertical position of the casting bow, forming a lightweight structure of the I-shaped cross section The body portion is formed, the lower edge portion of the body portion to form a step measuring portion horizontally, between the step measuring portion is formed a side wall at right angles, while the front side of the body portion height adjustment bolt is provided in the female screw hole of the protruding flange The leveling caster of the continuous casting machine, characterized in that the level is mounted on the center of the upper edge of the body portion parallel to the step measuring unit, the horizontal position measuring table is extended by the bolt to the vertical lower portion of the side wall By providing.

The positioning gauge 1 has a light-weight body portion 10 having an I-shaped cross-sectional structure, the lower edge of the body portion 10 roll 49 of the casting bow (110a) and the pinch roll ( Step measurement unit 12a, 12b, 12c facing the outer circumferential surface of each of the first and second rolls 120a and 120b of the 120 and the first roll 130a of the straightening device 130; 12d). The step measurement units 12a, 12b, 12c, and 12d are parallel to each other in the longitudinal direction X, and form sidewalls 14a, 14b, and 14c, respectively, which are perpendicular to each other in the vertical direction Y. (14d), the side wall (14d) has a length corresponding to the design reference step height between the 48th roll (110b) and the 49th roll (110a) of the casting bow, the step measuring section (12a) and (12b) ) Has a length corresponding to the design reference step height between the 49th roll (110a) of the casting bow 110 and the first roll (120a) of the pinch roll 120, the sidewall (14b) is The side wall 14a has a length corresponding to the design reference step height between the first roll 120a and the second roll 120b of the pinch roll 120, while the side wall 14a is kept straight with the second roll 120b of the pinch roll 120. It has a length corresponding to the design reference step height +1.0 m / m between the first roll (130a) of the device (130).

In addition, one side end portion is coupled to the side wall 14c by a plurality of bolt members 16 so that a horizontal position measuring table 18 extending vertically is detachably connected, and an upper side edge of the body portion 10. In the center there is a flat base 24 to which the leveler 20 is coupled by the bolt 22 so that the level difference 20 is parallel in the longitudinal direction X of each of the step measurement portions 12a, 12b, 12c, and 12d. Is formed.

In addition, a female screw hole 26a is formed at the center of the protruding flange 26 on the front side of the body portion 10, and a height adjusting bolt 28 made of a male screw is screwed into the female screw hole 26a. The upper end of the height adjustment bolt 28 is integrally connected to the handle 30 and the lower end is integrally connected to the plate 32 placed on the 48th roll of the casting bow.

Positioning gauge 1 of the present invention configured as described above, the step portion measuring portion 12d as shown in FIG. 2 across the first roll (130a) of the linear holding device 130, the body portion 10 When the plate 32 positioned on the front side of the casting bow 110 is placed on the 48th roll 110b of the casting bow 110, the step measuring unit 12a is positioned on the 49th roll 110a of the casting bow 110. The step measuring units 12b and 12c are respectively positioned on the first and second rolls 120a and 120b of the pinch roll, respectively, and the horizontal position measuring table 18 is the first roll 120a of the pinch roll 120, respectively. Close to the side, and then adjust the position of the height adjustment bolt 28 so that the scale of the leveler 20 is horizontal while rotating the height adjustment handle 30, so as to measure the stepped portions 12a, 12b, 12c. Hold 12d horizontally, respectively. When the horizontal maintenance operation of the positioning gauge 1 is completed in this way, the height of the side wall 14a connecting the step measurement unit 12c and the step measurement unit 12d is the number 2 roll 120b of the pinch roll 120 and Since the design reference step height between the first roll 130a of the linear holding device is maintained at +1 m / m, the gap between the step measurer 12c and the second roll 120b of the pinch roll is maintained at 1 m / m, The gap between the step measurement unit 12a and 12b and the first roll 120a of the pinch roll 120 and the 49th roll 110a of the casting bow 110 must also be maintained at 1 m / m so that the casting bow and the pinch roll It is installed at the normal design reference height for the linear holding device.

The gap between (12c) becomes larger or smaller based on 1m / m. Therefore, even when the first roll 120a and the second roll 120b of the pinch roll 120 are adjusted in the range of 0 to 0.3 m / m, the height adjustment range is sufficiently included within 1 m / m, so that the operator may measure the step. (12a) 12b, 12c, the gap between the 49th roll 110a of the casting bow 110 and the 1st roll 120a of the pinch roll and the 2nd roll 120b as the clearance gauge 40 by measuring You can quickly measure the vertical height of the casting bow and pinch roll. Therefore, as in the prior art, the first and second rolls 120a and 120b of the pinch roll are not affected by the height of 0 to 0.3 m / m, and the vertical height can be accurately measured. In addition, the horizontal position of the casting bow is measured by measuring the gap between the 49th roll (110a) of the casting bow and the horizontal position measuring table 18 as the gap gauge 40, the measuring interval of the design reference horizontal interval-horizontal position measuring table If it is true, it is judged to be correct, and if it does not match, it is immediately known that the horizontal position is not suitable. Therefore, in the horizontal position measuring operation of the casting bow, since the piano wire 160 and the tape measure 170 do not have to be used as in the prior art, the horizontal position measuring operation is made very quickly and accurately.

As described above, according to the present invention, when the casting bow of the continuous casting machine is coupled to the pinch roll and the linear holding device, the productivity of the maintenance work can be greatly improved by quickly and accurately measuring the vertical and horizontal positions.
