Abstract
Description
Technical Field
[0001] The utility model relates to a level gauge scale suitable for operation in a narrow space of a skin-pass mill rolling line, and belongs to the technical field of skin-pass mill rolling line maintenance and measurement equipment. Background Art
[0002] The skin-pass mill is the core equipment in a continuous annealing line. After annealing in the annealing furnace, the strip enters the skin-pass mill for processing to improve processing performance, adjust the strip surface roughness, and enhance surface quality. During the rolling process, once the upper support roll of the skin-pass mill enters its operating position, it remains stationary. This means that the position of the upper support roll indirectly indicates the position of the rolling line, and the level of the upper support roll represents the level of the rolling line. The level of the skin-pass mill rolling line is crucial to its proper operation. Excessive tilt can even affect the surface quality of the strip, resulting in ripples and thick edges. Therefore, regular measurement and calibration of the rolling line level is necessary. However, the narrow space between the screw press and the upper support roll makes conventional level gauges impractical. Using a 3D laser tracker for measurement is difficult, labor-intensive, costly, and time-consuming, making point selection difficult and labor-intensive. To simplify the measurement method while ensuring accuracy, it is necessary to design a level gauge suitable for use in confined spaces and capable of being operated by a single operator to meet the requirements for measuring horizontal deviations in the skin-pass mill rolling line. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a level scale suitable for the narrow space of the skin-pass mill rolling line. The level scale can measure the horizontal deviation of the skin-pass mill rolling line under the premise of ensuring the accuracy requirements, so as to make adjustments to ensure the rolling accuracy. The operation process is safe and fast, and meets the quality control requirements.
[0004] The technical solution of the utility model is:
[0005] A level scale suitable for use in a narrow space of a skin-pass mill rolling line comprises a magnetic base, a fixed connecting frame, bolts, and a scale.

The fixed connecting frame is an N-shaped plate frame, and the distance between the two opposite side plates of the N-shaped plate frame of the fixed connecting frame matches the distance between the two side surfaces of the magnetic base. The N-shaped plate frame of the fixed connecting frame is sleeved on the cubic magnet of the magnetic base, and the lower surface of the upper horizontal plate of the N-shaped plate frame of the fixed connecting frame is aligned with the cubic magnet of the magnetic base. The upper surface is tightly connected, and the inner sides of the two side plates of the N-type plate frame of the fixed connecting frame are tightly connected to the two side surfaces of the cube magnet of the magnetic base.
