Production process of oil-free precoated steel plate

Abstract

The invention discloses a production process of an oil-free precoated steel plate. The production process comprises the following steps: uncoiling, degreasing, cleaning, passivating, painting, curingand warehousing. With the production process, steel plates which can be coated with films without further treatment are produced, a manufacturer can directly coat the steel plates with the color filmsfor use, and the use amount is determined as demanded; and front and back coatings on the surfaces of the steel plates can play an anti-corrosion role, users do not need to worry about rusting in thestorage process, and thus the use flexibility is enhanced.

Description

technical field [0001] The invention relates to a steel plate production process, in particular to an oil-free pre-coated steel plate production process. Background technique [0002] Most of the door frames and door bodies used in houses are made of solid wood or wood-grain film-coated panels. Compared with the two, the production efficiency of film-coated panels is faster and the production cost is lower. Therefore, the use of film-coated color panels The door frame and door body have been more popularized. There are two main production processes for the existing film-coated panels. The first is the continuous production line for film coating. This process is completed from the substrate through a series of processes at one time. The process needs to be completed at one time, requiring a relatively large continuous production line. It is difficult to meet the demand for small batches of personalized wood grain effect film-coated color plates, and the cost will increase dur...

[0002] Most of the door frames and door bodies used in houses are made of solid wood or wood-grain film-coated panels. Compared with the two, the production efficiency of film-coated panels is faster and the production cost is lower. Therefore, the use of film-coated color panels The door frame and door body have been more popularized. There are two main production processes for the existing film-coated panels. The first is the continuous production line for film coating. This process is completed from the substrate through a series of processes at one time. The process needs to be completed at one time, requiring a relatively large continuous production line. It is difficult to meet the demand for small batches of personalized wood grain effect film-coated color plates, and the cost will increase during production; the second is the single-sheet film-coated process , the steel plate is degreased, cleaned, and coated after cutting. Because the steel plate is cut and then degreased, cleaned, and coated, the production efficiency is not high. Although for small batches of coated color plates with personalized wood grain effects The demand can be met, but not for mass production
