Problems solved by technology
[0002] The guide rollers of the coiling furnace of the medium and heavy plate coil factory have been in high-temperature operation for a long time. Affected by the temperature and the tension of the coil, the sleeves of the guide rollers will run to both sides, and the positioning lock nuts on both sides are easily damaged after being impacted.
In this case, the service life of the guide roller of the coiling furnace is short, and it will have a certain impact on the shape of the rolled steel plate.

Embodiment Construction
[0013] A method for transforming guide rollers of a coiling furnace provided in this embodiment, the structure is as follows figure 1 As shown, the axial direction of the guide roller casing is fixed by the lock nut 1, and the lock nut 1 is fixed on the shaft through threads, and a lock nut 2 2 is added outside the lock nut 1, and the nut 2 is threaded with the lock nut 1 1 The connection is fixed. There is a gap between the lock nut one 1 and the lock nut two 2, and a stop gasket for fixing the guide roller sleeve is arranged in the gap. The circumferential direction of the guide roller sleeve is fixed with a positioning key, and the positioning key is stuck in the keyway of the shaft and the guide roller sleeve to prevent the sleeve from moving in the circumferential direction.
[0014] In addition to the above-mentioned embodiments, the present invention can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformat...

The invention discloses a coiling furnace guide roller transformation method, and relates to the technical field of steel production equipment. A guide roller sleeve is axially fixed through a first lock nut, the first lock nut is fixed onto a shaft through a thread, a second lock nut is additionally arranged on the outer side of the first lock nut, and a second nut is fixedly connected with the first lock nut through a thread. A guide roller is technically improved, the sleeve is better fixed onto a mandrel, and the sleeve is fixed and positioned, so that the service life of the guide rolleris prolonged, and the shape of a rolled plate is improved.
Description
technical field [0001] The invention relates to the technical field of iron and steel production equipment, in particular to a method for reforming guide rollers of a coiling furnace. Background technique [0002] The guide rollers of the coiling furnace of the medium and heavy plate coil factory have been in high temperature operation for a long time. Affected by the temperature and the tension of the coil, the guide roller sleeves will run to both sides, and the positioning lock nuts on both sides are easily damaged after being impacted. In this case, the service life of the guide roller of the coiling furnace is short, and it will have a certain impact on the shape of the rolled steel plate. Therefore, the structural form needs to be improved. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for reforming the guide roller of the coiling furnace. The guide roller sleeve is fixed axially by the loc...
