250kg induction furnace furnace structure selection summary table

Induction Furnace 250kg of composition: 250kg induction furnace furnace furnace shell consists of four parts, an induction coil, lining, etc. gearbox tilting furnace furnace structure wherein selecting two ways: as a reducer in the way tilting furnace The supply melting furnace of aluminum alloy structure is commonly known as 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 . 250kg induction furnace because of its small size , generally choose aluminum shell reducer structure .

 How large is the closed cooling tower calculation method for the 250kg induction furnace medium frequency induction furnace ?

Choice: integrated layered tower closed - loop water cooling tower ZXZ-N 20 T

Select a mixed water tower to calculate a closed loop cooling tower with a formula of 200kw ¡Á 0.5 ¡Á 860 ¡Â 5000 = 20T .

5. What are the technical requirements for cooling water in each cooling section of the 250kg induction furnace ?

Different frequency induction furnace cooling portion cooling requirements different from water, an induction coil, a capacitor of the cooling water system using industrial cooling water pressure, the pressure is maintained at 0.15-0.2mpa, water temperature maintained at 20-35 ¡ã C inlet water temperature temperature below 55 ¡ã C.

 How large is the reservoir for the 250kg induction furnace?

The 250kg induction furnace consists of two parts, which are divided into intermediate frequency power supply and furnace body. The same reservoir can be used to cool the outlet water temperature to be controlled within 55 ¡ã C. The reservoir is 20 cubic meters : the cooling effect is poor, it is easy to block, and the general investment The minimum, the cooling effect is general.

How many transformers does the 250kg induction furnace need ?

The power of the intermediate frequency power supply used in the 250kg induction furnace determines the power. The ordinary melting power is 160kW and the melting speed is 250kW . Fast smelting is 250kW ( 1kW per kilogram of molten iron ) so you can consider a 160-250 KVA transformer.

How to calculate the cable of 250kg induction furnace ?

For example: IF power induction furnace 250kg maximum power of 200kw, frequency power supply into a cable 200KW = 200000/380 / 1.732 / 2 = 151mm2, the cable should be selected to 185mm2.

 Determination of energy consumption of 250kg induction furnace

The higher the power of the medium frequency induction furnace, the more power is saved, the energy consumption of the molten iron furnace: 650 KW.h/t temperature 1550 ¡ã C , melting furnace energy consumption 750 KW.h / t temperature 1550 ¡ã C.

 What does ¡° 0.25 ¡± for the aluminum shell 250kg induction furnace mean? ¢­

It is the specification of the furnace body, that is, the tonnage. The intermediate frequency furnace generally has 0.25T , 0.35T , 0.5T , 0.75T , 250kg , 2T , 3T , 5T , 10T, etc.

Aluminum shell 250kg induction furnace is an intermediate frequency coreless induction melting furnace ( non-vacuum ). It can be controlled by silicon static medium frequency power supply for induction and heating of copper, aluminum, stainless steel and other non-ferrous metals . Generally , it is divided into aluminum according to furnace capacity. There are two kinds of shell structure and steel shell structure. The aluminum shell structure generally adopts a tilting machine-powered tilting furnace method ( there are also a few hydraulic tilting furnaces ) , and the steel shell type structure generally adopts a hydraulically powered tilting furnace method.

11. What information does the customer need to provide to the supplier before purchasing the 250kg induction furnace ?

1. The 250kg induction furnace must 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 furnace needs water cooling equipment, and the configuration of the 250kg induction furnace contains water cooling equipment.

4. The structure of the medium frequency 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 medium 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.
