Speaking of the heating mode of the roller, in the actual application, it will include heat conducting oil heating, followed by steam heating, and also electric heating and electromagnetic heating. In the current form, in the market, we will use electromagnetic heating roller in the practical application, that is, an energy-saving way.

To say that the advantages of electromagnetic heating roller, we actually need to pay attention to the roller heat conduction oil and its steam heating, and its electrical heating mode of defects. In view of this, we should pay attention to the fact that the heat conduction oil should be heated directly with a burner or an electric rod, and the heat conduction oil can be directly recycled into the roller with an oil pump for heating.

Roller adopts steam or hot water into the roller for heating, especially the process of heat conduction oil heating roller, not just because of its thermal efficiency is lower, also will be slow on its thermal conductivity, so that we will find that it is actually also will often appear the phenomenon such as run, run, drip, leak, in order to give member maintenance equipment has brought considerable workload and difficulty.

Especially when using thermal oil heating roller and its on the thermal efficiency is lower, not only on its own thermal conductivity can be slow, moreover, on the other, it is also often run, run, drip, leak phenomenon, thus, is also brought maintenance equipment employees particularly large workload, and it is difficult.

Later, on the roller electromagnetic heating, it will occupy less land, the production site will be very simple. Correspondingly, in terms of heat conduction oil itself, in fact, an external circulation system is required. In terms of electromagnetic induction heating roller, heat conduction oil and related transmission pipeline system are not needed, so it is actually relatively simple.
