As a new subject, induction heating has been widely used in the past 30 years. Its importance is particularly prominent in today's energy shortage. Rapid technological progress, more and more widely used. After the reform and opening up, China began to develop induction heating technology, its application prospects are very broad.

 

 

1. Induction heating characteristics

(1) The heating temperature is high and it is non-contact heating.

(2) High heating efficiency.

(3) fast heating speed.

(4) The temperature is easy to control.

(5) It can be heated locally.

(6) Easy to realize automatic control.

(7) Good working environment, almost no noise and dust.

(8) Less land occupation and high production efficiency.

(9) It can heat workpieces with complex shapes.

(10) The workpiece is easy to heat evenly, and the product quality is good.

(11) The solution has an electromagnetic stirring effect during the smelting process. The molten metal composition can be uniformly adjusted, the solution temperature is uniform, and there is no local high temperature. Reducing metal burning is more important for smelting rare metals.

 

2. Advantages of induction heating

The first is low energy consumption. The actual billet heating thermal efficiency of induction melting furnace and induction diathermy furnace can reach 65% ~ 75%, while the actual billet heating thermal efficiency of flame furnace and various chamber furnaces is only about 30%.

Second, this type of furnace does not require the necessary preheating process, such as coal stoves, gas stoves and resistance stoves. Easy to use, simple operation. It can work continuously for a long time, and can also start or stop working at any time as needed. It can also work fully manually, fully automatically or semi-automatically, which has an absolute advantage in production scheduling.

Third, there is no need to heat the workpiece as a whole, but local heating can be selected, so the power consumption is low, the workpiece deformation is small, and the heating speed is fast, which can make the workpiece reach the required temperature in a very short time, so as to reduce the oxidation and decarburization of the workpiece surface. It can be used for heating of iron and steel materials, such as steel, tungsten and molybdenum, as well as aluminum, titanium, zirconium or heat treatment of niobium.

Fourth, induction heating equipment can be installed on the production line, which is convenient to realize the automation and mechanization of the production line, easy to manage, effectively reduce transportation, save manpower, and improve production efficiency.

Fifth, induction heating also has the advantages of high power utilization, environmental protection and energy saving, safety and reliability, and good working environment.

Based on the above advantages, when electric energy replaces non-renewable energy such as coal, oil and natural gas, and gradually becomes the dominant energy in the heating field, induction heating is more and more widely used in smelting, heating and other fields. Electric heating, especially induction heating applications have a very broad application prospects, induction heating equipment manufacturers have a broad space for development.

 

3. Application in automobile manufacturing

The vigorous development of the automobile industry has brought unprecedented development opportunities to the auto parts industry. Induction heating technology is more and more widely used in the field of automobile manufacturing.

In terms of melting, casting is an easy-to-shape metal working method. The casting method can be used to manufacture various parts of different sizes and complex shapes on automobiles. It can be said that in the development of the automobile industry, everything can be fully utilized, and almost all casting processes and methods can play a great role in the automobile industry.
