China electromagnetic induction heating roller manufacturer
Electromagnetic heating roller coated iron equipment unit
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 coated iron is mainly composed of Marco iron uncoiling part, welding and iron performance quality, substrate heating, coating unit, cooling unit, product and oil coiling, among which the key core part is the heating area and coating unit of the substrate. The temperature above the melting point of the steel strip film is heated by the preheating part of the electromagnetic induction heating roll, and the hot melt bonding between the substrate and the film is carried out by the extrusion of two symmetrical pressure rollers. The hot bonded steel strip is cooled rapidly by a cooling device to ensure rapid recrystallization of the molten polymer.
