Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] The rolling mill arch alignment method of the present invention includes longitudinal center deviation and verticality detection, lateral center deviation and verticality detection, and the two detections are carried out at the same time; the rolling mill arch is adjusted accordingly according to the detection results, and the detection feedback is performed, and the rolling mill arch is adjusted accordingly , until the corresponding technical requirements are met.

[0036] Among them, the longitudinal center deviation, verticality detection and adjustment include the following steps:

[0037] A. Tighten the anchor bolts of the rolling mill archway, for example, tighten the anchor bolts according to the 50% torque of the final anchor bolts. If the anchor bolts are not tightened, the value measured by the rolling mill archway will change after the anchor bolts are ti...

Abstract

The invention discloses an alignment method of a rolling mill house, and relates to the technical field of rolling mill equipment mounting and detecting. The problems that an existing alignment method is not comprehensive and is complex and low in reading accuracy, and the corresponding technical requirements are hard to meet are solved. According to the adopted technical scheme, the alignment method of the rolling mill house comprises the steps of longitudinal center deviation and perpendicularity detection and adjustment and transverse center deviation and perpendicularity detection and adjustment; firstly, foundation bolts of the rolling mill house are screwed up; then, a theodolite is erected at the longitudinal mounting center datum point of the rolling mill house; after measuring points are selected on the rolling mill house, the distance between each measuring point and the longitudinal center line is measured, finally, longitudinal center deviation and perpendicularity are calculated, and corresponding adjustment is carried out; in a similar way, transverse center deviation and perpendicularity detection is carried out; and according to detection results, an adjusting manner is determined, and detection is carried out after adjustment till the technical requirements are met. According to the alignment method of the rolling mill house, alignment of the rolling mill house can be achieved simply and fast, measuring is convenient, and accuracy is high.

Description

technical field [0001] The invention relates to the technical field of rolling mill equipment installation and detection technology, in particular to a method for detecting the longitudinal center deviation and perpendicularity of a rolling mill archway, and the transverse center deviation and perpendicularity. Background technique [0002] During the installation process of the rolling mill archway, the technical requirements for the installation of the rolling mill archway are high, and there are many inspection data, especially the requirements for the longitudinal center deviation and verticality of the rolling mill archway, the lateral center deviation and the verticality installation accuracy are very high. [0003] The installation accuracy of the rolling mill is mainly reflected in the alignment accuracy of the rolling mill archway. At present, the hanging wire method is used to detect the center deviation and verticality. For example, the patent document whose publ...
