Audited Supplier The calender roll of the ordinary paper machine calender is a harder cold cast iron roll. For a sheet with an uneven surface, the roller surface will only touch the convex part of the surface, and not the low part. The tightness of the contact part is increased, and the strengthened pressure forms a light spot, which makes the surface characteristics uneven. Soft calendering technology uses the denaturation of the elastic roller to absorb unevenness of the paper surface, so that the paper surface is completely in contact with the iron roller surface. After calendering, the tightness of the paper changes smoothly and continuously, and the surface characteristics of the paper are invalid; The area is wide, the calendering time is long and the specific pressure is relatively reduced, which can reduce the thickness (small strength loss) and improve the smoothness.
Structure principle
The roller in the calender is the main part of the auxiliary machine for extruded sheet (sheet) material, and its manufacturing accuracy and working conditions have a greater impact on the quality of the product. The roller body is generally made of seamless steel pipe, and then the end plate, shaft and roller body are welded to form a roller blank.
