Correctly apply induction furnace is related to the actual production efficiency. Some factors shall affect the work efficiency of the intermediate frequency furnace.
Intermediate frequency furnace power
The power of the intermediate frequency furnace should be based on the material of the heated metal, heating temperature, heating time and heating weight and other data, through the calculation and combined with practical experience to design a reasonable intermediate frequency furnace heating power. IF furnace power is greater than the required heating power, harmonics and reactive power increases, power consumption increases; IF furnace power is less than the required heating power, the heating efficiency is reduced.
Current frequency
Medium frequency electric furnace current frequency will directly affect the thermal efficiency of the medium frequency electric furnace inductor, if the choice of current frequency is too high, it will prolong the heating time, heat loss increases, thermal efficiency is reduced.
Electric furnace inductor end voltage
Try to avoid the use of low voltage and high current induction heating. Improve the medium frequency electric furnace inductor end voltage can save energy.
Induction loop current density
Medium frequency electric furnace induction loop current density is large, the power loss will increase, medium frequency electric furnace inductor electric efficiency is reduced.
Quality of copper coils and cables
Medium frequency furnace ?to try to choose high-quality copper as the raw material for coils and cables, increase the cross-section of the induction coil and transmission line.
Temperature
Reduce the temperature of the medium frequency furnace transmission line and coil.
Continuous smelting
Prolong the continuous smelting time of the intermediate frequency electric furnace, electric furnace ? run as far as possible to work at full load, avoid half-power operation.
