Industrial Electric Heating



The industrial electric heating consists of several processes which mainly differ in the temperature at which they occur.

In the case of industrial furnaces we mainly analyze the medium temperature’s processes (between 400 and 1150 ° C) and high temperature’s ones (over 1150 ° C) , the firsts are usually metal heat treatment processes or all processes that include the use of plastics or otherwise non-metallic materials, the seconds are typically the classic metal soldering, brazing, welding, melting process.

The main methods of electrical heating include conduction, convection ,radiation but the latest innovations in this way concern the use of electromagnetic fields to heating material.

The use of electric heating compared to other methods such as, for example, the fuel has many advantages :

  • A better precision control on the temperature of the oven.
  • The ease of reaching very high temperatures.
  • The possibility of direct thermal energy in an exact processes are usually cleaner and quieter.
  • They do not emit excessive heat into the surrounding.
  • High response speed.
  • Ability to make quick work cycles.

From these elements is unclear how much the electric heating is technologically superior to other methods, allowing processes more technical, precise and efficient. Despite this, however, there are downsides to using this technology, which allow the other to continue to exist, all of the cost. To activate a system that includes an electrically heated machine must not forget the costs involved in the adaptation of the network infrastructure industrial power to a massive demand for energy and the cost of energy.

For these reasons it is very important that manufacturers of electric heating systems where possible to adopt policies aimed at energy saving. This aspect as well as making the most commercially attractive products, may result in an incentive to the development of the industrial production, through refurbishment of the park equipment installed.
