What is 90KW Medium Frequency Induction Melting Furnace Advantages?

The working frequency of 90KW medium frequency induction melting furnace is between 50Hz-10kHz, and it needs to be adjusted by frequency converter. Intermediate frequency induction melting furnaces have advantages over industrial frequency induction melting furnaces due to their high electrical and thermal efficiency, short melting time, less power consumption, less land occupation, lower investment, flexible production and easy implementation of process automation.

90KW medium frequency induction melting furnace is suitable for smelting all kinds of cast iron, especially suitable for smelting alloy cast iron, ductile iron and vermicular graphite cast iron, and has strong adaptability to the charge. The variety and lumpness of the charge can be changed in a wide range.

The 90KW medium frequency induction melting furnace has the advantages that other cast iron smelting furnaces do not have. It has achieved remarkable development in recent years and has been widely used in cast iron production.

The heating method of traditional heating equipment is to heat itself first, and then transfer the temperature to the metal workpiece. The heat transfer process will cause heat loss and cause the surrounding temperature to rise, while the 90KW medium frequency induction melting furnace induction heating method It makes the metal workpiece heat itself.

The 90KW medium frequency induction melting furnace is made of heat-insulating materials. Through non-contact heating of the metal, the heat loss is small, and the thermal efficiency is as high as about 70%. Under the same conditions, it can save 30%-70% of electricity compared with resistance heating, and preheat Time shortened by 70%.

Since the heating process almost only generates heat inside the workpiece, the 90KW medium frequency induction melting furnace itself does not generate high temperature, which extends the service life of the melting furnace and reduces maintenance costs.

The intermediate frequency induction melting furnace adopts a computer control system with a high degree of automation. The high-power intermediate-frequency induction melting furnace has a short melting period and a large overheating rate.

90KW Medium Frequency Induction Melting Furnace

The heating power supply passes alternating current to the induction coil to generate alternating current magnetic flux of the same frequency. The charge in the induction coil generates an induced electromotive force to make the charge heat. Heating according to this principle is called induction heating.

In order to heat the charge to a certain temperature to melt it, the induced electromotive force in the charge is required to be as large as possible. There are two ways to do this: increase the current I through the coil or increase the power frequency. In the induction furnace, if a higher frequency power supply is used, the magnetic field is stronger, the power density generated in the same metal is higher, and the charge is heated faster. The magnitude of the induced current and the calorific value of the charge is not only related to the shape of the charge, but also to the material, and is related to the resistivity and permeability of the metal charge.

How is induction different from natural gas/fuel?

Combustion furnaces and induction furnaces generate heat in two completely different ways. In the combustion furnace, heat is generated by burning fuels such as coke, oil or natural gas. The burning fuel makes the internal temperature of the furnace higher than the melting point of the charge placed inside.

It heats the surface of the charge and refractory material to melt the metal. The induction furnace generates heat cleanly and does not burn fuel. The electric current in the metal heats and melts the metal from the inside. Through induction, you can heat directly.

 

Can I use the same melting system to melt iron and non-iron?

The melt system may be specifically designed for the most efficient smelting of iron or non-ferrous metals, so it may need to be modified to handle materials originally designed to achieve the same efficiency and productivity. Please note that you should contact your refractory supplier to ensure that your refractory is suitable for the metal you are melting.

 

What is the heating process of metal melting furnace

In order to heat non-conductive materials such as plastic or glass, induction can be used to heat a conductive base such as graphite, which then transfers heat to the non-conductive material.

Induction heating can be used in processes as low as 100ºC (212°F) and as high as 3000°C (5432°F). It can also be used for short heating processes lasting less than half a second and heating processes lasting several months.

Heat Treatment (surface hardening, quenching, annealing, tempering).

Used for quenching various hardware and tools, such as pliers, wrenches, hammers, axes, tightening tools and shears (orchard shears).
