Electromagnetic heating roller for coated iron (electromagnetic induction heating roller) Equipment unit size: φ 320 ~ 600 mm× l960 ~ 2200mm Temperature: 100~220℃ Linear speed: 10~100m/min Linear pressure: max 400kN/m Surface treatment: hard chromium plating, mirror/super mirror application: PVC sheet calendering/metal material calendering.The production process of coated iron The production of coated iron adopts a compound process of high temperature, high pressure and rapid cooling. The production line of coated iron mainly consists of uncoiling part of chromium-plated iron, welding and apparent quality inspection of iron, substrate heating, coating unit, cooling unit, product inspection and oiling winding, among which the core part is the heating area of substrate and coating unit. The preheating part of the electromagnetic induction heating roller heats the steel strip to a temperature above the melting point of the film, and the substrate and the film are hot-melt bonded by extrusion of two symmetrical pressure rubber rollers. The hot-bonded steel strip is rapidly cooled by a cooling device to ensure the rapid recrystallization of the melted polymer.Application industries of coated iron: 1. Applications in food metal cans: food cans, beverage cans, four-turn lids, candy cans, tea cans, easy-to-open lids, etc. 2. Applications in chemical tanks: chemical tanks, paint tanks, paint tanks, two-piece aerosol tanks and various top and bottom covers. In particular, the blank film covering processing technology can be applied to all kinds of three-piece cans. 3. Application in decorative cans: portable ashtray, gift box, stationery box, jewelry box, cigarette box, wine box and so on. 4. Applications in other industries: building plates, walls, suspended ceilings, security doors, floors, awnings and so on.Theoretically, there are many places available, but in fact, the advantage of coated iron is its application in food and beverage cans, especially in two-piece can. There are also many coated iron three-piece cans in Japan, which is mainly to avoid the TULC technology patent of Toyo cans.At present, the annual consumption of two-piece can (steel and aluminum) in China is about 30 billion. Based on the annual growth rate of 10%, the domestic demand for two-piece can will reach nearly 50 billion in five years, with a net increase of 20 billion. With more and more strict requirements of environmental protection and increasingly scarce resources, metal packaging materials that can be recycled and recycled are increasingly favored by people. Therefore, it can be predicted that the domestic market prospect of two-piece can made of green and environmentally-friendly coated iron is very broad.
