Induction Furnace Temperature Range

Induction Furnace Temperature Range

Under the action of the alternating electromagnetic field in the induction furnace, eddy currents are generated inside the material to achieve the effect of heating or melting. Under the stirring action of the alternating magnetic field, the composition and temperature of the material in the furnace are relatively uniform. The induction furnace temperature range: the forging heating temperature can reach 1250°C, and the melting temperature can reach 1650°C.

The main components of an induction furnace include an inductor, a furnace body, a power supply, a capacitor, and a control system.

The medium frequency induction furnace refers to an induction furnace powered by a power supply with a current frequency in the range of 150-8000Hz. The use frequency is 150-2500Hz. As the capacity of the furnace increases, the frequency of the current used decreases. The capacity of the domestic medium frequency induction furnace ranges from 50KG to 20T, and the current frequency is correspondingly 2500-150Hz.

In addition to heating or smelting in the atmosphere, the induction furnace can also be heated or smelted in vacuum and argon, neon, and other protective atmospheres to meet special quality requirements.

Induction furnaces have outstanding advantages in diathermy or melting soft magnetic alloys, high-resistance alloys, platinum group alloys, heat-resistant, corrosion-resistant, wear-resistant alloys, and pure metals.

Induction furnaces are generally divided into induction heating furnaces and melting furnaces.

There are two types of melting furnaces: core induction furnaces and coreless induction furnaces.

The cored induction furnace has an iron core passing through the inductor and is powered by a power frequency power supply. It is mainly used for smelting and heat preservation of various cast iron, brass, bronze, zinc, and other metals. The electric efficiency is over 90%. The melting cost is low, and the maximum furnace capacity is 270 tons.

The coreless induction furnace has no iron core passing through the inductor and is divided into power frequency induction furnace, triple frequency induction furnace, generator set intermediate frequency induction furnace, thyristor intermediate frequency induction furnace, and high-frequency induction furnace.

The advantage of the induction furnace is that the loss of raw materials is much smaller than that of other equipment. Induction heating furnaces include forging heating furnaces, induction tempering furnaces, and induction hardening furnaces.

Series induction furnace features:

(1) High melting efficiency, good power-saving effect, compact structure, and strong overload capacity.

(2) The temperature around the furnace is low, there is less smoke and dust, and the working environment is good.

(3) The operation process is simple and the smelting operation is reliable.

(4) The metal composition is uniform.

(5) The melting temperature rises quickly, the furnace temperature is easy to control, and the production efficiency is high.

(6) The utilization rate of the furnace is high, and it is convenient to replace the variety.

(7) The long arc-shaped yoke shields magnetic flux leakage and reduces external reluctance. There is magnetic flux leakage at both ends of the shielded coil. Got better support.

The induction furnace has fast heating speed, high production efficiency, less oxidation, and decarburization, and saves material and forging die costs.

Since the principle of intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself. Ordinary workers can continue the forging task ten minutes after going to work with the intermediate frequency electric furnace, and there is no need for professional workers to burn the furnace and seal the furnace in advance. There is no need to worry about the waste of billets heated by coal furnaces caused by power outages or equipment failures.

Due to the fast heating speed of this heating method, there is less oxidation. Compared with coal-fired furnaces, at least 20-50 kg of steel raw materials can be saved per ton of forgings, and the material utilization rate can reach 95%.

Due to the uniform heating and the small temperature difference between the core and the surface, the life of the forging die is greatly increased in forging, and the surface roughness of the forging is also less than 50um.

The working environment is superior, improving the working environment of workers and the image of the company, with no pollution, and low energy consumption.

Compared with the coal furnace, the induction heating furnace will no longer be baked and smoked by the coal furnace under the scorching sun and can meet the requirements of the environmental protection department. At the same time, it can establish the company's external image and the future development trend of the forging industry.

Induction heating is a more energy-saving heating method in electric heating furnaces. The temperature range of induction furnaces is heated from room temperature to 1100 °C, and the power consumption per ton of forgings is less than 360 degrees.

The temperature range of the induction furnace is evenly heated, the temperature difference between the core and the surface is small, and the temperature control accuracy is high.

Induction heating generates heat in the workpiece itself, so the heating is uniform and the temperature difference between the core and the surface is small. The application of the temperature control system can realize the precise control of the temperature range of the induction furnace and improve the product quality and qualified rate.

The intermediate frequency induction furnace heating device has the advantages of small size, lightweight, high efficiency, excellent thermal processing quality, and a favorable environment. It is rapidly eliminating coal-fired furnaces, gas furnaces, oil furnaces, and ordinary resistance furnaces. It is a new generation of metal heating equipment.

The intermediate frequency furnace is the main equipment in the casting, forging, and heat treatment workshop. Its working stability, reliability, and safety are the guarantee for the normal and stable operation of the casting, forging, and heat treatment production line in flow operation.
