Hot rolling roll
Because of its special design structure, hot rolling roll has high strength, toughness and heat resistance. It is used for forming high density plastic sheet and heating composite of non-woven fabric.
High quality alloy steel 38CrMoA1A, 42CrMo, 60CrMoV and 9Cr2Mo are selected as the bulk materials. After mechanical processing and heat treatment, the surface hardness can reach HRC58-62.
There are two kinds of design structures: inner spiral liner and peripheral drilling. The inner installing spiral liner or the drilling around the roller body circularly guides the hot oil, which makes the temperature difference between the two ends of the roller surface smaller and the thermal efficiency higher.
The roller has high overall strength, small deformation under high-strength counter pressure and uniform product thickness;
The heat exchange is efficient and uniform, and the roller surface temperature is balanced and stable;
It is suitable for surface calendering and embossing of thin plastic sheet such as PC / PMMA, non-woven fabric and leather.
