Electromagnetic induction heating roller-Film coated iron equipment application

The laminated steel, commonly known as laminated steel, used in the canning industry, is made by laminating PET, PC, PE or PP films with metal sheets (galvanized sheet, cold-rolled sheet, aluminum sheet, stainless steel sheet). Traditional metal cans must undergo coating processing on the inside, and the substance bisphenol A contained in the coating method can have harmful effects on both the human body and the environment, especially on canned food. The birth of metal plate coating technology is a progress in the production of metal cans. With its widespread application, traditional metal can production processes and technologies will be overturned, and productivity, production costs, cleanliness and hygiene, environmental protection, and other aspects will also make great strides forward. The production line of laminated iron mainly consists of the uncoiling part of Marco iron, welding and iron performance quality, substrate heating, laminating unit, cooling unit, product and oil coating winding, etc. The key core parts are the heating area of the substrate and the laminating unit. Preheat the steel strip film to a temperature above its melting point using electromagnetic induction heating rollers, and apply heat fusion bonding between the substrate and the film through the squeezing of two symmetrical pressure rollers. The hot pressed steel strip is rapidly cooled by a cooling device to ensure that the melted polymer quickly recrystallizes.

Application industry
