Application of Laser Heat Treatment Technology in Corrugated Roll Packaging Machinery

1. Corrugated roller laser quenching process:

Mainly used for the quenching of corrugating rollers such as 48CrMo, with a quench depth of 0.8-1.2mm, a quenched width of 16-18mm, and a laser scanning speed of 20-30mm/s. The surface finish of the workpiece after laser quenching is not damaged and the workpiece is not deformed. Quenching hardness of 57 to 60 on the Richter scale, Rockwell hardness HRC65, and can be adjusted according to process needs, Ф 450 watts roller laser quenching efficiency of about 78 to 100 minutes / only.

2. Corrugated roll laser cladding process:

Coating metal and hard alloy powders on the surface of corrugating rollers such as 48CrMo to form a new alloy layer and metallurgically bond with the substrate to improve the high temperature resistance, wear resistance, fatigue resistance, corrosion resistance of the workpiece, or to restore parts size of. Cladding single layer thickness can be adjusted in the range of 0.1-2.0mm, to meet the different surface enhancement and repair process requirements, the total thickness of the coating is not limited. Cladding hardness reaches Rockwell HRC65.
