Description

Technical Field

[0001] The utility model relates to the field of metal hot coating devices, in particular to a high temperature resistant immersion roller. Background Art

[0002] When the cold-rolled alloy steel strip or steel wire is hot-dip coated, the steel strip or steel wire must be passed through a molten metal alloy flume at about 230-650°C. The flume is provided with one or more immersion rollers to support the cold-rolled alloy steel strip or steel wire. The existing immersion rollers in the coating tank have poor corrosion resistance, easy damage, short service life and other shortcomings during use, which cannot meet the needs of users; in response to this problem, the Chinese utility model with application number 201320519020.0 proposes an improved immersion roller. The technical solution adopted by the utility model is: an improved immersion roller, including a cylindrical roller body and roller shafts arranged on both sides of the roller body, the roller body is fixedly connected to the roller shaft, and the roller body includes a roller body, a rubber lining layer coated on the roller body, and an anti-corrosion layer coated on the outer surface of the rubber lining layer from the inside to the outside, and the anti-corrosion layer is a polytetrafluoroethylene coating. The advantages of the utility model are: reasonable structure, long service life, and can effectively reduce production costs; but the problems existing in the roller body structure when in use are:

[0003] When facing alloy strips or steel wires of different widths, it cannot limit and support them well, and support deviation is prone to occur. When this type of roller is set as a solid roller, its weight is not convenient for operation and use, and when it is set as a hollow roller, its overall stability needs to be improved, and the supporting operation cannot be well realized; at the same time, this type of roller structure achieves corrosion resistance by setting an anti-corrosion layer on the surface of the rubber lining layer, but in the actual process of supporting the alloy strip or steel wire, the rubber lining layer itself is deformed to a certain extent due to the weight, which will affect the adhesion effect of the coating on its surface, and then affect the corrosion resistance. At the same time, this type of roller cannot achieve a good high temperature resistance effect. Utility Model Content
