How to arrange 3T medium frequency induction melting furnace ? Please see the figure below for answers.


3 T medium frequency induction melting furnace appearance structure


What information does the customer need to provide to the supplier before purchasing the induction melting furnace?

1. Induction melting furnace should have space for layout, and it is necessary to provide the area and layout of the plant.

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 induction melting furnace requires water-cooling equipment, and the induction melting furnace configuration contains water-cooling equipment.

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

5. The power supply of the induction melting furnace is an intermediate frequency power supply. The circuit structure of the intermediate frequency power supply is divided into an inverter parallel connection and an 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.

A good way to correctly and quickly select the " 3T medium frequency induction melting furnace "

1. Induction melting furnace transformer capacity selection

The 3T medium frequency induction melting furnace should select a 2500KVA transformer. Secondary output voltage is 660v

Selection basis: value of transformer capacity = value of induction melting furnace power supply x 1.2

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

1. Selection of Line Voltage of 3T Medium Frequency Induction Melting Furnace

3T medium frequency induction melting furnace power is 2000kw using six- phase 12- pulse 660v , 50HZ industrial electricity

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

1. According to the capacity requirements, determine the induction melting furnace with large tonnage.

The capacity of the induction melting furnace can be determined by 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 induction melting furnace

500kg induction melting furnace

1T medium frequency induction melting furnace

2 T medium frequency induction melting furnace

3T induction melting furnace

5T induction melting furnace

4. Selection of 3T medium frequency induction melting furnace body structure

The capacity of the 3T medium frequency induction melting furnace is small. The recommended choice is: the furnace body of the hydraulic steel shell .

The aluminum alloy structure commonly known as the aluminum alloy structure with the reducer as the tilting furnace method. 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 .

Determination of energy consumption of 3T medium frequency induction melting furnace

The power supply of the induction melting furnace is more power-saving, and the energy consumption of molten iron in 3T medium-frequency induction melting furnace : 5 5 0KW.h/t , energy consumption of molten steel 6 0 0 KW.h/t .

How to choose the induction melting furnace lining material?

1. 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 the appropriate lining material. jobs.

2. Induction melting furnace is a molten steel furnace using alkaline lining material mainly for fused magnesia. The 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 increase the melting speed of the induction melting furnace?

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

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

3.   Appropriate molten iron outlet temperature.
