The production process of color-coated steel coil

Color-coated coils are called color-coated coils or color-coated steel sheets in daily life.This product is made by continuously degreasing the surface of the steel strip through chemical conversion processes such as phosphating on the production line, and then baking the steel strip coated with an organic coating at high temperature.Generally speaking, the surface color of this kind of steel plate is brighter than the surface color, we also call this kind of steel plate color-coated coil and color-coated plate.

The basic concept of color-coated coils is also called color steel coils.It adopts composite technology, which highly combines steel and colored peritoneum.It also has excellent properties of various materials, greatly improving the chemical stability of materials.Color-coated coils have more effective rust protection and corrosion protection.Color steel not only has the excellent quality of steel in terms of flexibility, plasticity, pressure resistance, wear resistance, heat dissipation and high temperature resistance, but also outstanding in color, finish and hand feel.It is worth mentioning that all raw materials used in the production of color coating rollers are non-polluting and environment-friendly materials, and the production process is completely dust-free.Both production and later use have high environmental protection characteristics.

The production method of color coating coil is: on the continuous unit, cold rolled strip steel and galvanized strip steel (electric galvanized and hot dip galvanized) as the bottom plate.The color-coated coil has undergone surface pretreatment (degreasing, chemical treatment), and is coated with one or more layers of liquid paint by roller coating. The plate obtained after baking and cooling is a coated steel plate.

Because the coating can have multiple colors, the coated steel plate is usually referred to as colored coated steel plate.As the coating is carried out before the forming and processing of steel plate, it is also called precoated steel plate.The technological process of color-coated steel coil is as follows: color-coated steel plate is cold-rolled steel plate and galvanized steel plate as the base material, through surface pretreatment (degreasing, cleaning, chemical transformation), continuous coating (rolling coating method), baking, cooling and the product.

For the use of color-coated rolls, we must choose different types of color-coated rolls to manufacture different products.According to the use of household appliances, optical materials, decorative materials, building materials and packaging five categories.Among them, the manufacturing process of household appliances color-coated coils is fine and perfect. Of course, the quality requirements of such color-coated rolls are relatively much higher.
