5. 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 " 250kg induction melting furnace "

1. Induction melting furnace transformer capacity selection

The 250kg induction melting furnace should be a 315KVA transformer. Secondary output voltage is 380v

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 250kg induction melting furnace inlet voltage

250kg induction melting furnace power is 200kw, three-phase five-wire system 380V , 50HZ industrial power

2.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 .

3. The capacity tonnage requirements to determine how much selected induction melting furnace.

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

50 0kg induction melting furnace

1T induction melting furnace

2T induction melting furnace

3T induction melting furnace

5T induction melting furnace

Selection of 250kg induction melting furnace body structure

250kg capacity induction melting furnace is small, it is recommended to select: the furnace is aluminum reducer tilting furnace configuration mode

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 250kg induction melting furnace

The power supply of the induction melting furnace is more power-saving, the energy consumption of 250kg induction melting furnace and molten iron: 580KW.h/t , energy consumption of molten steel 6 5 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.
