Problems solved by technology

In the past, during the construction process, the measuring method of the disc ruler was often used to determine the horizontal and vertical centerlines of the equipment installation. Since the disc ruler will deform under different temperatures and uneven tension, the error is very large, even if the length of the ruler is corrected, it cannot be guaranteed. Limit deviation of strand radius R ± 0.5mm

Embodiment Construction

[0013] With reference to the accompanying drawings, two channel steels 9 perpendicular to the transverse datum line IIy and of the same height are set on the foundation one 5, and a vertical line L1 perpendicular to the transverse datum line IIy and L2, set the measuring point on L1 and L2, the distance between the measuring point and the transverse reference line IIy is less than the maximum measuring length calibrated by the micrometer, weld the measuring point block 8 at the position of the measuring point set on the channel steel 9, and measure the point mark The head of the block 8 is arc-shaped, and the head of the measuring point marking block 8 is used as a forward measuring point, and an auxiliary transverse reference line Ya parallel to IIy is made at the head position of the measuring point marking block 8, and the auxiliary transverse reference line Set up a theodolite at any point A on the line Ya, determine a reverse measurement point on the channel steel 9, adjus...

Abstract

The invention relates to a measurement method for controlling limit deviation of casting strand radius R of a conticaster, which uses the combination of a micrometer and a theodolite, guides segments in different planes into one plane and carries out segmented measurement. The method has the advantage of high measurement precision, and can ensure the measured limit deviation to be within positive / negative 0.5mm.

Description

Technical field: [0001] The invention relates to a measurement method for controlling the limit deviation of the cast stream radius R of a continuous casting machine, which belongs to the field of physical measurement. Background technique: [0002] The equipment foundation of the continuous casting machine is a stepped foundation. Before the equipment is installed, the horizontal and vertical centerlines are measured and set on the stepped foundation, and the radius R of the casting stream is determined according to the horizontal centerline. In the past, during the construction process, the measuring method of the disc ruler was often used to determine the horizontal and vertical centerlines of the equipment installation. Since the disc ruler will deform under different temperatures and uneven tension, the error is very large, even if the length of the ruler is corrected, it cannot be guaranteed. The limit deviation of strand radius R is ±0.5mm. Invention content: [00...
