First of all, let's take a 500kw induction melting furnace as an example, and compare the values of the three different inverters mentioned above in power consumption, power factor, and approximate price of the induction melting furnace. The values are as follows:　
1. 　Heating temperature of induction melting furnace 

with thyristor series inverter : 1550 ℃ 
tons Power consumption: 650kwt / t 
power factor: 0.98 
2. 　Heating temperature of induction melting furnace 

with thyristor parallel inverter : 1550 ℃ 
ton Power Consumption: 700kwt / t 
Power Factor: 0.92 

3 , IGBT Series Inverter Induction Melting Furnace 　

Heating Temperature: 1550 ℃ 　　
ton Power Consumption: 650kwt / t 　　
Power Factor: 0.98　　
With the advancement of the times, the renewal of induction melting furnaces is endless, and the induction melting furnace has surpassed the power-frequency furnace in a few years to become the current one. The core induction melting furnace in the foundry industry. With the continuous improvement of induction heating technology, current high energy saving and low cost have become the new development direction of induction heating induction melting furnace. When it comes to energy saving, it must be mentioned that a core part of the induction melting furnace - inverter , but the inverter of the induction melting furnace is generally divided into thyristor series inverter, thyristor parallel inverter and IGBT series Inverter. So which inverter is more practical and energy saving in induction melting furnace? Today, I will do a comparison of the induction melting furnace inverter for everyone, let everyone understand the induction melting furnace inverter more intuitively.

According to the comparison values of the induction melting furnace inverters listed above, it can be seen that among the three types of induction melting furnace inverters previously proposed, in terms of energy saving, the related data of series inverters have obvious advantages over parallel inverters, and in In the comparison of two series inverters, the price of thyristor series inverter is better than IGBT series inverter. In summary, the thyristor series inverter is a better inverter choice for energy saving of induction melting furnaces. Of course, when choosing an induction melting furnace, customers can also choose a more suitable induction melting furnace based on factors such as production characteristics and financial conditions.
