Abstract

The invention discloses a striped embossed home appliance board production process. The production process includes: selecting a substrate-pickling-rolling-galvanizing-painting-flat embossing-shearing- Finished product; the substrate is a hot-rolled steel coil. Through the production process of the striped embossed home appliance board provided by the invention, a galvanized color-coated board with three-dimensional lines can be obtained, which enriches the appearance of the home appliance board and satisfies consumers' needs for diversified appearance of the home appliance board.

Description

technical field [0001] The invention relates to the field of steel surface treatment, in particular to a striped embossed home appliance board production process. Background technique [0002] Conventional TV backplanes are either galvanized sheets as the substrate, which generally require surface treatment again, or color-coated sheets as the substrate. The surface effect of color coating is often metal wire drawing or flat pattern, and the surface shape of the two is single. It can't meet the user's demand for diversified appearance, and it needs to be processed again during use, which brings certain environmental protection pressure to home appliance manufacturers. At present, flat embossing is also used to change the shape of the galvanized sheet or the back sheet of the color-coated sheet, but the substrate is often cracked during the stamping process. Even if the elongation rate is increased by 50% on the original basis, the probability of stamping cracking is still ve...
