Multicolored steel sheet mfg. method and system

Abstract

A method for manufacturing multiple colors, styles or patterns on the surface of a steel plate and a multi-color steel plate manufacturing system implementing the method. The steps of the method include: using a first monochrome dye to print on the surface of the steel plate; drying the first color printed on the steel plate at a certain temperature; cooling the dried steel plate; The second single-color printing operation is performed on the surface of the color-printed steel plate; the double-color printing on the steel plate is dried at a certain temperature; the dried steel plate is cooled; the second color is printed on the surface of the steel plate. The third single-color printing operation; drying the three colors printed on the steel plate at a certain temperature; cooling the dried steel plate; performing the fourth single-color printing on the surface of the steel plate printed with the third color Printing operation; drying the four colors printed on the steel plate at a certain temperature; cooling the dried steel plate; coating paste on the surface of the steel plate that has been printed and dried; The coated steel plate is dried at a certain temperature; the coated and dried steel plate is cooled; finally, a multi-color steel plate is made by laminating a protective thin layer on the surface of the steel plate.

Description

technical field [0001] The present invention relates to a method and system for manufacturing multi-color steel plates, more specifically, to a method for manufacturing multi-color steel plates by printing various delicate, single-color graphics, styles or patterns on the surface of steel plates And a multi-color steel plate manufacturing system for efficiently utilizing the method. Background technique [0002] In the traditional color steel plate, a single color dye is used on the surface, and the pattern printed on the surface appears monotonous in most cases, so it cannot meet the exquisiteness that requires various aesthetic needs and styles in various fields. Image user needs. [0003] In recent years, various attempts have been made to produce multi-color steel sheets by printing patterns or figures with more colors using dyes of various colors, however, these attempts have not yet achieved satisfactory results. [0004] In reality, there are some multi-color steel ...

AI Technical Summary

Problems solved by technology

But the color state quality of these surface styles or patterns is relatively poor, and the color printing process is time-consuming

In addition, the manufacturing process of this product is more complicated and the price is higher

[0005] In addition, the traditional multi-color steel plate has a decisive shortcoming. When the steel plate is bent or bent or it is subjected to a slight load, cracks or cracks will appear on the surface of the dye
