In an embodiment, the fastener is a fastening bolt.

In an embodiment, the repair layer is formed by knife coating a loctite material.

In an embodiment, the loctite material is loctite 44143 polymer composite.

The repairing surface is coated with the Letai 44143 polymer composite material in a scraping mode to form a repairing layer, then a lining plate is installed through a fastener (a fastener demolding agent layer and a fastener composite material layer are arranged before the repairing layer is constructed) (the lining plate demolding agent layer is arranged before the repairing layer is constructed, the Letai 44143 polymer composite material is coated (the repairing layer is finished), then the lining plate is installed in place), then the repairing layer is solidified, and the material is completely solidified for 24 hours at normal temperature (24 ℃).

The utility model discloses the repair time is short, and restoration face department has good compressive strength and corrosion resistance, has improved rolling mill space clearance precision after the restoration, and the repair effect is better.

Example 2

A rolling mill housing, having the rolling mill housing anticorrosion repair structure as described in embodiment 1.

Example 3

Referring to fig. 3, a repairing aid, which is used for the rolling mill housing anticorrosive repairing structure according to embodiment 1, and includes a material plate 30 (a square plate) and a scraper (not shown in the figure, used for scraping the loctite material on the material plate on the repairing surface, which refers to the prior art), the scraper and the material plate are used in cooperation, a holding portion (not shown in the figure, disposed on the back of the material plate, i.e., deviated from the side where the loctite material is disposed) is disposed on one side of the material plate 30, the holding portion may be a protruding block or a handle, which is convenient for a worker to hold the material plate, a barrier 30a is disposed on one end of the material plate 30, and the barrier is designed to facilitate the use of the material plate.
