Color coated steel plate

Color coated plate, also known as color steel plate, color plate. Color coated steel plate is cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), in a continuous way coated with paint (roll coating method), after baking and cooling products. Coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed, it provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc., has played a good effect of replacing wood with steel, efficient construction, energy saving, pollution prevention and so on.

Process flow

The main production processes of the common two-coating two-drying continuous color coating unit are:

Decoiler——stitching machine —— press roll——tension machine uncoiling looping soda-wash degreasing——cleaning, drying passivation——at the beginning of drying—— touched —— the early drying——finish fine tu —— finish drying - —— air cooling —— coiler looper —— coiler —— (lower coiler to be packed into storage).
