Title:
METHOD AND DEVICE FOR PRODUCING FILM-COATED METAL PLATE
Document Type and Number:
WIPO Patent Application WO/2018/001179
Kind Code:
A1
Abstract:
A method for producing a film-coated metal plate, comprising the steps of: (1) pre-heating and soaking a metal plate; (2) hot coating the metal plate with a thin film; (3) cooling the metal plate; (4) compressing the metal plate to dry it; (5) reheating and post-processing the metal plate. This method is able to produce a metal plate having a thin film coated on the surface thereof and to easily control the thickness of a melting layer of the thin film in the process of production, especially control the difference between the thicknesses of the melting layers on both sides; and meanwhile, this method is able to increase the cooling rate. Accordingly, this method enhances the performance of the film-coated metal plate and increases the application range of the film-coated metal plate by means of a more environmentally friendly producing process and lower energy consumption, and is able to produce good economic and social benefits. The film-coated metal plate produced by this method can be used for food and beverage package. A device for producing a film-coated metal plate, which can produce a film-coated metal plate using the described method for producing a film-coated metal plate. The device comprises: an induction heating apparatus, an offset roller (4), a thin film guide roller (6), a film-coating roller (7), a cooling apparatus (9), a compressing and drying roller (12), a reheating apparatus (14) and an air cooling apparatus (15).
