The electromagnetic induction heating roller of Roewe Roll Manufacturing Company has no sealing oil medium (i.e. no oil discharge sealing heating), which makes the temperature difference ≤ ± 1 ℃, truly achieving safety, uniform temperature, environmental protection, and energy conservation!
Note: The electromagnetic heating roll is sealed and heated with oil, just like an ticking time bomb scenario! At any time or any day, there will be a serious safety hazard!
Roewe Roll truly masters the core technology of electromagnetic induction heating rolls!
Electromagnetic heating roller application fields: rolling, calendering, laminating, peritoneum, drying, preheating, embossing, embossing, etc. in plastic sheets, sheets, films, paper, leather, cloth, rubber, anti-counterfeiting laser materials, hot stamping, textile, printing and dyeing, metal, non-woven materials, electronics and other industries.
1) Material processing: Select high-quality 45 # steel, alloy steel, and high-quality steel, and use heat treatment technology for quenching, stress relief, and quenching. The inner wall of the roller is finely turned with uniform wall thickness, and the hardness after quenching can reach HRC55-58.
2) Internal structure: composed of a central axis, insulation layer, heating layer, radiation layer, insulation layer, reflection layer, high-temperature coating layer, etc. from the inside out.
3) Heating method: Electromagnetic induction heating, with an energy-saving efficiency of 50-70%. The surface temperature of the electromagnetic induction heating roller can reach over 400 ℃. Surface treatment: plated with hard chromium, sprayed with ceramics or tungsten carbide, treated with precision grinding, grinding and polishing, with a roughness of Ra0.01 (smoothness level 14).
5) Processing accuracy: Roll surface temperature difference ≤ ± 1 ℃, thermal deformation ≤ 0.01mm, straightness, runout, coaxiality ≤ 0.005mm Features and advantages: Electromagnetic heating rolls have many advantages such as high temperature control accuracy, good temperature uniformity, fast heating and cooling speed, easy maintenance, low energy consumption, safety, environmental protection, and pollution-free.
