Induction Furnace High Temperature - Metal Smelting

What is the heating principle of an induction furnace that can generate thousands of degrees of high temperature in a few seconds and instantly burn the metal red?

As an essential material in modern times, metal is used in almost every field, and it needs to be processed in order to turn it into products of various shapes and functions.

To process a metal, it needs to be heated, because heating is the easiest way to change the shape of a metal. However, the traditional heating method is to generate a high temperature environment by burning fuel, and then place the metal in this environment for heating. But this heating method takes a long time. With the continuous change of the times and the continuous advancement of technological development, there is now a method that can quickly heat metals, which is Induction Furnace High Temperature

Working Principle

How exactly does induction heating work?

Induction heating mainly uses the principle of magnetic field to heat, and its heating system is mainly an induction coil, a power supply and a metal workpiece that needs to be heated.

The induction heating power supply converts the AC power into a higher frequency AC, transmits it to the induction coil, and generates an electromagnetic field in the coil.

Since the metal workpiece that needs to be heated is also a conductor, the circles of magnetic induction lines generated by the induction coil will directly penetrate the metal workpiece placed in the coil to form a current closed loop, and the resistance of the metal is small, plus Higher current, when these high-current magnetic induction lines pass through the metal workpiece, the electrons inside the metal will be very active, collide with each other, and friction will generate heat energy, achieving the effect of rapidly heating the metal itself.

Characteristics of Induction Furnace High Temperature

1. Guarantee product quality

Induction heating doesn't require direct contact with open flames, and can guarantee the quality of all products. It only needs to set and calibrate the temperature, and each product will not have uneven heating and heating temperature deviation, which can ensure the heating quality of each product. And the power can be turned on or off instantly, the system is also able to measure the temperature of each individual metal part, and can record the data of each heated part.

Parts heated by induction will not be in direct contact with flames or other heating elements. The alternating current will generate heat inside the parts, reducing the scrap rate of heated products. Metal parts are heated in a closed loop of the coil, which is compared to the vacuum environment. , can also reduce the oxidation of parts.

2. Improve production efficiency

Because the heating speed is very fast, the production efficiency can be improved to the greatest extent. The high temperature of the induction furnace can make the equipment generate heat of more than 800~1000 degrees Celsius on the workpiece in a few seconds at the fastest. It can be said to start instantly without preheating or cooling. cycle.

The induction heating process can be done next to the metal forming machine without sending parts to other workshops or processing plants, saving time and improving efficiency.

3. Extend fixture life

Induction heating applies heat to specific locations on the metal and quickly transfers heat to an area of the part without heating any surrounding parts, which extends the life of fixtures and machinery.

4. More environmentally friendly & safer

Induction heating systems do not burn traditional fossil fuels, heating is a clean, non-polluting process that will help protect the environment. And it also eliminates smoke, waste heat, harmful emissions, and no noise, which improves the working conditions of employees.

Induction heating is also safer, with no open flames present to harm the operator or the environment, and non-conductive materials placed near the heating zone will not cause damage.

5. Reduce energy consumption

Induction heating is able to convert 90% of the energy into useful heat, compared to the typical 45% energy efficiency of ordinary furnaces, and since the induction process does not require preheating or cooling cycles, standby heat loss is also minimized.

It can be said that induction furnace high temperature heating is one of the cleanest, most effective, cost-effective, accurate and repeatable material heating methods available in the industrial field today.

Especially with the arrival of demand for advanced engineering materials, alternative energy sources, etc., the unique function of induction heating technology provides a fast, efficient and precise heating method for future industrial production.

Different furnace materials, production requirements, etc. need to be equipped with corresponding induction furnaces. For any needs or questions about induction heating equipment, smelting equipment, etc., please feel free to contact us.
