I. Overview
Electromagnetic induction heating roller has five advantages of "energy saving, fine control, environmental protection, stability and safety".
Ii. Detailed description:
1.1 main specifications and parameters of electromagnetic heating roller
1) commonly used specifications: 140 mm ~ 1200 mm x L500mm Φ ~ Φ L3000mm; (customized according to customer requirements)
2) surface temperature: 80℃ ~ 400℃; (customized according to customer requirements)
3) roller speed: 5 ~ 100m/min;
4) linear pressure: 10-50kg /cm;
1.2 processing technology and performance characteristics of electromagnetic heating roller
1) material selection: 45# steel, forged alloy steel (42GrMo,38 GrMoAl), high-quality imported steel, tempered, de-stressed and quenched with advanced heat treatment process. The inner wall thickness of heating roller is uniform, and the surface hardness after quenching can reach HRC50 ~ 58.
2) internal structure: from the inside to the outside, it is composed of central axis, heat insulation layer, heating layer, radiation layer, insulation layer, reflection layer, high-temperature coating layer, etc.
3) heating method: electromagnetic induction heating, environmental protection, energy saving efficiency up to 30 ~ 60%, electromagnetic induction heating roller surface temperature up to 400℃.
4) surface treatment: the imported formula is treated with hard chromium plating, with fine chromium layer and strong adhesion. (customized according to customer requirements)
5) machining accuracy: the surface temperature of the roller is even, temperature difference ≤ ±1℃, thermal deformation ≤ 0.01mm, flatness, runout, coaxiality ≤ 0.005mm.
Application fields of electromagnetic heating roller: preheating, embossing, calendering, laminating, printing, packaging, papermaking, laminating, plastic, rubber, textile, printing and dyeing, leather, metal rolling, nonwoven materials and other industries.
Especially high-grade cigarette package, brand cosmetics, fine food, wine and other products in the transfer printing, laser anti-counterfeiting technology of production process of the roll surface temperature uniformity and stability of requirements, processing environment spotlessness, through a combination of laser engraving machine and security software to implement the traditional electric carving machine can't achieve (spends, miniature, split lines, latent image, besmear carving) cigarette package, cypress paper and famous products anti-counterfeiting printing, line precision can reach 0.01 mm, miniature text precision can reach 0.5 mm. Electromagnetic induction heating roller with its "high efficiency, fine control, energy saving, environmental protection, safety" is the outstanding characteristics of its choice.
