The production of induction heating roller is the most complicated among all rollers. This paper makes a brief introduction.
The first problem is material selection. Common materials for roll shell include: 45 steel, 20 steel, 40Cr, 38CrMoAl, 40CrMoAl, 42CrMo, 45CrMo, etc. Appropriate materials should be selected according to the requirements of the application. The common materials for roll end is some diffirent, which include: 45 steel, 20 steel, 40Cr, 42CrMo, 38CrMoAl, 40CrMoAl, etc.
The description of the process is much complex. This is the process flow chart:
The surface treatment of some roller is not chrome plating, but Teflon coated, or ceramic coated. There are also some roller surface according to the need to do a variety of carving.
We can see from the above that the production process of induction heating roller is complex. With it's advantages, induction heating roller is especially suitable for the production of advanced polymer materials.
