Steel sheet continuous recoating and printing process

Abstract

The invention relates to a steel plate continuous coating and printing process, and the flow of the process is as follows: raw material coiling-->linking-->edge straightening--> steel belt storing-->degreasing-->water washing-->spray cooling-->hot air drying--> chemical processing-->indirect cooling-->bottom layer dyeing--> bottom dyeing drying--> hot air drying-->surface dyeing and back dyeing-->primary dyeing--> intermediate coating-->third coating-->drying-->surface checking-->steel belt storing-->hot air drying-->spray cooling-->drying-->fine coating-->separate coiling of products-->product packaging or size cutting-->product finishing; the invention has less investment and high benefit. And the invention adopts the printing technical theory and replaces wood with steel, and can produce various wood pattern effects and various patterns.

Description

technical field

[0001] The invention relates to a continuous overcoating printing process for steel plates. Background technique

[0002] At present, the steel plates used in the construction industry on the market are all single-color flat color-coated, mainly blue and red, with fewer tones, which are not suitable for decoration, so most users choose various wooden plates , and some also use various wood grain papers to stick on the inferior wooden boards to make the real ones look like real ones. The wooden board decoration did not look ugly at the time, but it will change color, deform or even fall off after a few years, and the cost is also low. How to make the steel plate become a checkered steel plate with various color patterns has become a big problem that the current steel plate color coating industry needs to solve.
