Description

Technical Field

[0001] The utility model relates to the technical field of color-coated plate production, in particular to a rust removal device for color-coated plate production. Background Art

[0002] Color-coated sheets are also called color-coated steel sheets. The production process of color-coated sheets mainly includes the following steps: 1. Substrate pretreatment: The substrate of the color-coated sheet can be a cold-rolled steel sheet, a hot-dip galvanized steel sheet, etc. The substrate needs to be pretreated first. Pretreatment includes processes such as degreasing, rust removal and washing to ensure the cleanliness and smoothness of the substrate surface; 2. Coating process: After the substrate is pretreated, it needs to be coated. Coating includes two steps: primer and topcoat. Primer is applied to increase the adhesion between the coating and the substrate and improve the anti-corrosion performance of the coating. Topcoat is to increase the decorativeness and weather resistance of the coating; 3. High-temperature curing: After coating is completed, high-temperature curing is required to ensure the durability of the coating. High-temperature curing generally uses baking furnaces, IR furnaces and other equipment to heat the color-coated sheet to a certain temperature to cure the coating.

[0003] At present, the rust removal work in the factory is mainly carried out by grinding and rust removal with a manual handheld rust removal machine when the steel coil is unrolled and transported.
