A good way to quickly and accurately select the "medium frequency induction melting furnace"

Time: 2019-07-04

1. Selection of transformer capacity of medium frequency induction melting furnace

Value of transformer capacity = value of MF induction melting furnace power supply x 1.2

The transformer is a rectifying transformer. In order to reduce the interference of harmonics, it is used as far as possible for the special plane, that is, one intermediate frequency induction melting furnace is equipped with a rectifier transformer.

2. Selection of incoming line voltage of medium frequency induction melting furnace

For medium frequency power supply for medium frequency induction melting furnace below 1000 KW, three-phase five-wire 380V and 50HZ industrial power are generally used. For medium frequency induction melting furnace above 1000KW, the focus is on using 660V incoming voltage.

3. According to the capacity requirements, determine the medium frequency induction melting furnace with large tonnage.

The capacity of the medium frequency induction melting furnace can be determined according to the weight of the individual pieces and the weight of the molten iron required for each working day.

The standard tonnage is as follows:

250kg medium frequency induction melting furnace

500kg medium frequency induction melting furnace

1T medium frequency induction melting furnace

2T medium frequency induction melting furnace

3T medium frequency induction melting furnace

5T medium frequency induction melting furnace

4. Selection of furnace structure

The melting furnace for the aluminum alloy structure with the reducer as the tilting furnace is commonly known as the aluminum shell furnace. The induction melting furnace of the steel structure with the hydraulic cylinder as the tilting furnace is commonly called the steel shell furnace. The steel shell furnace is a steel structure, and the aluminum shell furnace shell material is an aluminum alloy.

 

What information do customers need to provide to suppliers before purchasing an intermediate frequency induction melting furnace?

1. The medium frequency induction melting furnace should have room for layout, and the area and layout of the plant need to be provided.

2. The customer needs to provide the capacity of the transformer, the magnitude of the incoming line voltage, and the frequency of the incoming line voltage.

3. The medium frequency induction melting furnace needs water cooling equipment, and the configuration of the medium frequency induction melting furnace contains water cooling equipment.

4. The structure of the medium frequency induction melting furnace has a steel shell body and an aluminum shell body, which requires the customer to specify the furnace structure.

5. The power supply of the intermediate frequency induction melting furnace is the intermediate frequency power supply. The line structure of the intermediate frequency power supply is divided into the inverter parallel and the inverter series structure. The inverter series structure is energy-saving, the power factor is 0.98, and the line is stable. The inverter parallel structure is of the common type with a power factor of 0.92, which requires the customer to specify the line structure.

Determination of energy consumption of medium frequency induction melting furnace

The power supply of the medium frequency induction melting furnace is more power saving, the energy consumption of the molten iron furnace is 580 KW.h/t, and the energy consumption of the melting furnace is 630 KW.h/t.

 

The price of the intermediate frequency melting furnace?

Calculated by the power of the medium frequency induction melting furnace and the volume of the electric furnace. Different configuration prices vary.

 

How to choose the lining material of medium frequency induction melting furnace?

1. Medium frequency induction melting furnace lining material is divided into acid lining material, alkaline lining material, neutral lining material, coil cement, root melting material, medium frequency electric furnace tonnage, product molding temperature is different, it is very important to choose suitable lining material. work.

2. Medium frequency induction melting furnace is a molten steel furnace using alkaline lining material mainly for fused magnesia. The medium frequency induction melting furnace is a molten iron furnace. The acid lining material is a refractory material for quartz coreless induction furnace, and the material is acidic.

 

How to improve the melting speed of the medium frequency induction melting furnace?

1. Increase the power of the intermediate frequency induction melting furnace intermediate frequency power supply.

2. Choose a reasonable charge size and the correct feeding method.

3. Appropriate molten iron tapping temperature.

What does the 6-phase 12-pulse control system in the IF induction melting furnace mean?

In the intermediate frequency induction melting furnace rectification control circuit, each phase has a pair of pulses, and the three phases are six pulses, also called six pulses. Because the furnace has large capacity and high power, a special transformer is used, and two different windings (star and triangle) are used to provide two-way (2x3 phase) rectification. Therefore, the rectification system is simply referred to as "six-phase twelve-pulse" rectification. system.
