Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings.

[0014] See Figure 1 to Figure 3 , The figure shows a method for measuring the verticality and parallelism of the rolling mill housing of the present invention. Measuring the verticality and parallelism of the rolling mill housing includes the following steps:

[0015] Steps for measuring the verticality of the rolling mill housing: measure the verticality of the window of the rolling mill housing 3 and the verticality of the side of the stand respectively, that is, weld a wire frame 1 in the window of the rolling mill housing 3 and the side of the stand, and hang a thin wire on the wire frame. Steel wire 2, the lower end of the thin steel wire 2 is hung with a pendant 4, the wire pendant 4 is stably placed in an oil drum to prevent the thin steel wire 2 from swinging from side to side in a windy environment, and then fixed to the disc The inner diameter micrometer 5 on the magnetic bas...

Abstract

The invention discloses a mill stand perpendicularity and parallelism measuring method for measuring the perpendicularity and the parallelism of a mill stand. The method comprises a step of measuring the perpendicularity of the mill stand and a step of measuring the parallelism of the mill stand. The method takes advantage of a measuring technique of hanging steel wires at a window and a lateral surface of the mill stand and solves a problem concerning the measurement of the perpendicularity of the mill stand; and the method takes advantage of a measuring technique of downwardly hanging a steel wire at a lateral surface of the mill stand window and solves a problem concerning the measurement of the parallelism of the mill stand. Due to the utilization of the measuring technique disclosed by the invention, operation errors are reduced, operation error rate brought thereby is also reduced, and the measurement accuracy and the installation quality are improved.

Description

Technical field [0001] The invention relates to the field of mechanical equipment installation, in particular to a method for measuring the verticality and parallelism of a rolling mill housing. technical background [0002] With the increasing number of mechanical equipment installation projects, the installation accuracy of the rolling mill archway is getting higher and higher, especially in a windy environment, which will affect the measurement accuracy and the installation quality of the rolling mill archway. Summary of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a method for measuring the verticality and parallelism of the rolling mill housing, which reduces the operation error, reduces the occurrence rate of the operation error caused thereby, and improves the measurement accuracy and installation quality. [0004] The technical solution to achieve the above objective is: a method for measuring the ve...
