Luoyang Judian Metal Hot Processing Equipment Co., LTD is mainly engaged in the manufacture of complete sets of equipment in the metal thermal processing industry and the integration of the entire production line.
As an induction heating equipment manufacturer, this article is for everyone to popularize the economics of induction heating equipment. From the perspective of economics, it is difficult to make economic estimates because the equipment investment cost and the main fuel cost often change. However, from the relative trend of fuel costs, it is more advantageous to use electricity than to use fossil fuels, although the price of unit energy of fossil fuels such as oil and gas is still relatively cheap. The rise in the price of all fuels has focused more on the efficiency of the entire equipment.
Induction Heating
With the emergence of thyristor inverters and industrial frequency multipliers, as well as the development of vertical electric alternators and high-power high-frequency generators, it means that there is more room for people to choose induction heating power supplies under various investment cost conditions. In some applications, due to the unique properties of induction heating and no other options, it cannot be compared with other methods. In the case of higher power and larger equipment, induction heating is competitive with fossil fuel furnaces using oil and gas, direct resistance heating furnaces, indirect radiation heating furnaces and arc melting furnaces.
The change in terminal efficiency depends on the rated power, cooling form and equipment design. In some cases, additional input power transformers may have to be added to eliminate harmonic feedback to the power line. Sometimes a thyristor inverter is needed. The efficiency of the system will decrease due to transformer, transmission line and other external losses. The efficiency of the induction coil will vary with the material, as we have seen in Chapters 2 to 4. When the temperature of steel is below the Curie point, the efficiency can be close to the upper range in a tightly coupled induction coil. Non-ferrous metals or loosely coupled induction coils will give lower efficiencies.
