induction melting furnace inverter comparison, which one is better to use?

With the progress of the times, the equipment is constantly updated, and the intermediate frequency furnace has quickly surpassed the industrial frequency furnace in a few years and has become the current foundry industry by virtue of its advantages of fast heating speed and simple operation method. Core equipment. With the continuous improvement of induction heating technology, current high energy saving and low cost have become the new development direction of induction heating equipment. When it comes to energy saving, it must be mentioned that a core part of the intermediate frequency furnace type-inverter, but the inverter of the intermediate frequency 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 the intermediate frequency furnace? Today, the editor of Yuhua made a comparison of the inverter of the intermediate frequency furnace for everyone, let everyone understand the inverter of the intermediate frequency more intuitively.

Medium frequency grate

First of all, let's take a 500kw diathermy device as an example to make a comparison of the three different inverters mentioned above in power consumption, power factor, and approximate equipment price. The values are as follows:

1.Thyristor series inverter

Heating temperature:

Xtonne power consumption:

Power factor: 0.98

 Approximate price of equipment: 130,000 ~ 150,000 yuan

2.Thyristor parallel inverter

Heating temperature:

Xtonne power consumption:

Power factor: Approximate equipment price: 80,000 to 90,000 yuan

3.IGBT series inverter

Heating temperature:

Xtonne power consumption:

Power factor: 0.98

 Approximate equipment price: 170,000 to 190,000 yuan

According to the comparison values of the IF furnace inverters listed above, it can be seen that among the three types of IF furnace inverters previously proposed, in terms of energy saving, the related data of series inverters have obvious advantages over parallel inverters, In the comparison of series inverter, 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 intermediate frequency furnaces. Of course, when customers choose equipment, they can also choose more suitable equipment based on factors such as production characteristics and financial conditions.
