Problems solved by technology

Due to the verticality deviation of the precision square and the measurement deviation of the block gauge feeler will cause a certain error, and the specific value measured by different measurers will also produce a certain deviation
The error caused by this is large

Abstract

The invention provides an installation construction method of a high-speed wire rod finishing mill. Adjustable sizing blocks and sizing block grouting are adopted, sizing block anchoring bolts are fine-thread full-thread studs, each sizing block can be directly adjusted at a time to a required elevation by adjusting upper and lower nuts, then grouting is carried out with micro-expansion grouting materials, and the elevation is basically not changed; if base machining precision can be guaranteed, a base can reach the required elevation and levelness at a time by the sizing blocks. The base machining precision defect is overcome by additionally arranging a flat-thin sizing block set; according to central line adjustment in the method, a micrometer bound with a spirit level is matched with measurement through a theodolite so as to adjust the longitudinal central line and the transverse central line, the precision error is within + / -0.05 mm, and by means of the method, installation precision is guaranteed and the construction speed is high.

Description

technical field [0001] The invention relates to a construction technology for installation and adjustment of a high-speed wire finishing mill, in particular to a construction technology for installation and adjustment of a split-assembled high-speed wire finishing mill. Background technique [0002] At present, the finishing mills on the high-speed wire rod production lines of domestic iron and steel plants generally introduce the latest technology from American Morgan, and the equipment is directly imported or manufactured by Chinese companies using Morgan technology. The structural features of the equipment are as follows: it consists of a joint base, 10 conjoined roller boxes, a bevel gearbox, a synchronous gearbox and 2 transmission motors. The finishing mill base of this equipment is integrated with the inclined support; the roll box and the cone box are integrated; the horizontal base is a thick steel plate welded structure, and its size is 8500*938*1292mm. It belongs...
