The present invention relates to a mold copper plate inclination measuring device for performing the setting of the inclination of the mold copper plate in the continuous casting (Casting) and the level of adhesion to the mold, more specifically, the mold copper plate tilt The present invention relates to a mold copper plate inclination measuring device which easily performs the measurement and checking the adhesion state to the mold and maintains the accuracy of the measuring device as well as makes it permanently available.

In general, in the continuous casting operation as shown in FIG. 1, molten steel W injected into the mold 1 through the molten steel inlet 2 and the tundish 3 is formed in the mold 1 of a predetermined standard. The initial slab shape is determined by the product, which is solidified by primary cooling, so that the bottom portion of the slab 4 in the mold 1 has a smaller width than the upper part as shown in FIG. This will occur.

Therefore, the shrinkage of the different slabs 4 depending on the type of steel and the width of the product in the mold 1 is compensated by the inclination of the mold copper plate, so that the inner surface 1a of the mold copper plate 1 and the outer surface of the cast steel 4 are reduced. It is to maintain the shrinkage ratio (T) of the proper interval.

That is, as shown in FIG. 3, in order to bring the mold copper plate tilt measuring device into close contact with the mold copper plate, the motor 7 of the copper plate tilt operating device 5 is rotated to separate and engage the clutch 7 installed thereto. By setting the slope of the mold copper plate.

However, in the case of setting the mold copper plate inclination as described above, if the distance between the molten steel solidification part and the mold copper plate is large, the bottom of the solidification cast piece that has passed through the mold is larger than the upper part, and the inside of the molten steel solidification part is not solidified under the mold striking. As it exists in the state, it can not endure the static pressure and is torn, which causes the accident of molten steel leaking into the facility.

In addition, when the spacing between the molten steel solidified portion and the cast copper plate is small, cracks are generated at the edges of the slab 4 due to the increase in frictional force between the cast copper plate and the molten steel solidified portion, thereby causing deterioration of quality.

Therefore, such a mold copper plate measuring device is to play a very important role in equipment accident and cast quality.

The conventional mold copper plate inclination measuring device associated with this technique is a vertical plate 9 by measuring device 10 consisting of a fixed shaft 11 and a flow shaft 12, as shown in Figures 4 and 5 After adjusting the zero point using the mold, the mold 13 is formed so that the reference point 13 protruding from the fixed shaft 11 and the lower measuring point 14 are perpendicular to the horizontal bar 15 bent upwardly to the flow shaft 12. Closely adhere to the copper plate vertically, adjust the horizontal adjustment screw 16 to match the horizontal blister 17 to the center point, and set the mold copper plate inclination value set according to the steel grade and product width to the gauge 18 to adjust the vertical adjustment screw. 19, the flow shaft 12 moves about the flow point 20, thereby separating and engaging the clutch 7 by the motor 6 of the copper plate tilt measuring device 5 of FIG. It is to check whether the inclination with the copper plate inclination measurement gun 21 on the 15).

However, such a conventional mold copper plate inclination measuring device 10, the use method is complicated as described above, and as the frequency of use increases, various adjustment screws, reference points 13, deformation of the measuring point 14 is generated and measured The device is out of the error range (± 0.1 mm), there is a disadvantage that the error of the measuring device occurs.

In addition, since the measuring apparatus only measures the inclination of the mold copper plate, it is impossible to confirm whether the mold is in close contact with the mold, and thus there are many problems such as a deviation caused by the arrangement of the apparatus itself.

The present invention has been made to improve the conventional problems as described above, and its purpose is to facilitate the measurement of the inclination of the mold copper plate and the checking of the adhesion state to the mold example, and to maintain the precision of the measuring device for measuring the same. The present invention provides a mold copper inclination measuring device that can be used permanently while being maintained.
