Heat treatment equipment medium heating and infrared heating equipment

Medium heating and infrared heating equipment are also commonly used heat treatment equipment in heat treatment plants, which are described below.

1. The medium heating and heat treatment equipment uses the high-frequency electric field to act on the dielectric material, so that the electric dipole in the dielectric can produce high-speed vibration and generate heat energy to heat the material.

Main features:

① The material surface is evenly heated, fast heating and high thermal efficiency;

② Compared with other electric heating equipment, its electric efficiency is lower and its cost is higher;

③ High frequency electric field is harmful to human body, so necessary protective measures must be taken;

At the same time, it is necessary to prevent the interference and harm of high-frequency leakage to the operation of radio, television and other electronic equipment. It is mainly used for drying of wood, paperboard, cloth and casting mud core, drying and freezing of fish food, welding of PVC plastic and preheating of plastic powder.

2. The main features of infrared heating heat treatment equipment are as follows:

① In the occasion of large temperature difference, infrared heating is relatively rapid;

② According to the infrared absorption band of the heated object, the spectrum of the infrared light source can be selected reasonably, which can improve the heating speed and save electric energy;

③ Infrared heating elements can be flexibly and conveniently combined into various heating equipment, such as water heater, oven, warming box, and can also be used for local heating of large-scale devices. It is mainly used for food baking and heating, paint baking, glass annealing and drying and heating in the processing of some industrial products.
