Induction melting furnace

Induction melting furnace is an induction heating equipment used to heat molten metal. It is widely used in the foundry industry. What are the induction melting furnace systems? The following details the melting system of the induction melting furnace.

1. According to the cooling medium of the transformer, the power supply device of the induction melting furnace system-transformer can be divided into two types: dry-type transformer and oil-immersed transformer. In the induction melting furnace industry, we commonly use induction melting furnace rectifier transformers. This type of transformer is an oil-immersed transformer, which is far superior to ordinary transformers in terms of overload capacity and anti-interference ability.

2. Intermediate frequency power supply of induction melting furnace: The intermediate frequency power supply cabinet is the core part of the induction melting furnace system. The intermediate frequency power supply is composed of rectifier and inverter, capacitor bank, thyristor, AC contactor, and water-cooled cable.

3. The function of the capacitor cabinet of the induction melting furnace system is to provide reactive power compensation for the induction coil. It can be simply understood that the size of the capacitor directly affects the power of the device. It should be noted that the capacitance of the parallel device is only one type of resonant capacitance (electrothermal capacitance). In addition to series resonant capacitor elements (capacitors), filter capacitors are preferable. This is also a national standard that can be used to determine whether a device is a parallel device or a series device.

4. The furnace body of the induction melting furnace. The furnace body of the induction melting furnace is used for metal heating and melting. It is called an inductor or an inductor coil. According to the furnace shell, it is divided into a steel shell furnace body or an aluminum shell furnace body.

5. The cooling water of the induction melting furnace system. The cooling water control system is an indispensable part of an induction melting furnace system. It is also a very important part. It can be said that the quality of the cooling system can directly affect the decision. The failure rate of the induction melting furnace system is improved. There are currently three commonly used induction melting furnace system cooling methods, traditional pool cooling, open cooling tower, and closed cooling tower..

Pool cooling takes up a lot of space and cooling water. The water quality is poor and easy to scale. Now it is basically useless. The open cooling tower has a large cooling workload, low cost, and a moderate footprint. Now we have some large-tonnage (above 10 tons) furnace bodies still in use. Because of the quality of cold water, the power cabinet is not recommended. The closed cooling tower has the advantages that the circulating water can be completely closed to isolate the influence of the external market environment. The water quality problem can be effectively guaranteed and the water consumption is small. The area is small and the cooling capacity is large. It is a commonly used cooling method now..

6. The hydraulic station of the induction melting furnace system

The hydraulic pressure of induction melting furnace system is mainly used for melting furnace. Generally, one furnace body is equipped with two hydraulic cylinders, which are combined with hydraulic pressure to form a tilting furnace system. The hydraulic tilting furnace has the advantages of outstanding stability and ability to stay at any position. This is an essential part of the entire induction melting furnace system.

The functions that the hydraulic station must have are as follows

1) The oil pump must use a gear pump, which has the advantages of stable working pressure and low noise;

2) Oil cooler must be equipped (water cooling is best, air cooling can be used for small hydraulic stations);

3) The oil inlet and return port must have filters to remove impurities in the cooling medium;

4) The tank body, tubing, etc. must be pickled and phosphated.

7. The connection material of the induction melting furnace system, the connection of the transformer to the power cabinet, and the copper bar/aluminum bar connection are preferred. The connection between the intermediate frequency power supply cabinet and the capacitor is made of copper wire, and the connection between the furnace body and the capacitor is connected with a water-cooled cable, and the length is not more than 6 meters.

8. the induction melting furnace consists of:

Medium frequency power supply – capacitor cabinet – aluminum shell or steel shell furnace – hydraulic tilting furnace system – remote control box – Closed loop cooling tower.

9. the price of induction melting furnace

The price of the induction melting furnace is calculated according to the power of the intermediate frequency power supply and the volume of the furnace body. Different configuration prices vary. This price is for reference only. Contact us will have a very low price, please consult the specific price.Firstfurnace@gmail.com
