Materials : High grade 45#steel, alloy steel, precision steel.

Processing:heat treating ,destressing,finish turning,quenching.

Inner structure: 

The structure from inside to outside : center shaft, insulation layer, heating layer, radiation layer, heat preservation layer,

reflecting layer and high temperature coating layer.

Heating method:

Electromagnetic induction heating .( energy-saving efficiency: 50%-70%. The maximum temperature of the roller surface can reach above 400℃).

Surface treatment 

hard chrome plating,spraying ceramic or tungsten carbide.,finish grinding, grinding and polishing.

Machining precision: 

1 After quenching,hardness of roller surface is HRC55~58

2 Roughness is Ra 0.01,finish14,temperature difference ≦±1℃,thermal deformation ≦0.01mm,straightness≦0.01mm 

 run out≦0.005mm, coaxiality≦0.005mm

Advantages: 

High temperature control precision , good temperature uniformity, high heating and cooling speed, easy maintenance, 

low energy consumption, safety, environmental protection, no pollution and so on.

Applications:

Used in plastic sheet, plate,film, paper, cloth, rubber, Anticounterfeiting laser materials,wash gold, textile, 

printing and dyeing, metal,nonwovens, electronic and other industries for calendering ,Compositing, peritoneum, 

drying, preheating, embossing,stripes forming etc.
