High frequency machine and high frequency furnace technology is currently high heating efficiency and speed of metal materials. Electricity consumption can be reduced by 30 percent or even 40 percent, which is one of the means of emission reduction and consumption reduction advocated and applied by all countries.
Usually people heat things up.
First, the use of coal, oil, gas and other energy combustion to generate heat;
Second, the use of electric appliances such as electric furnace to convert electrical energy into heat. Only by heat transfer (heat conduction, heat convection, etc.) can the heat be transferred to the object that needs to be heated, so as to achieve the purpose of heating the object. Because of these modes of heating, the object being heated heats up by absorbing external heat. So they're all indirect heating. The natural transfer law of heat is: heat can only be transferred from the high temperature region to the low temperature region, from the high temperature body to the low temperature body, and from the high temperature part to the low temperature part naturally. Therefore, it can only be heated if the external heat and temperature are greater than or higher than the object being heated.
It takes a lot of energy to build a higher temperature zone that is much hotter and much hotter than the object being heated. Such as furnace, oven, etc. In this way, not only a small part of the heat can be transferred to the heated body, resulting in a great waste of energy. And the heating time is long, in the process of combustion, heating, will also produce a large number of harmful substances and gases. They will not only cause corrosive damage to the heated body, but also cause pollution to the atmosphere. Even if the electric energy heating method such as electric furnace is used, there are still some disadvantages such as low efficiency, high cost and slow heating speed.
