Application And Development Of External Inductry Heating Technology

(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) Can be heated locally;

(6) Easy to realize automatic control;

(7) The working environment is good, with almost no noise and dust;

(8) The work occupies less space and has high production efficiency;

(9) Can heat workpieces with complex shapes;

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

(11) The solution has electromagnetic stirring during smelting. The composition of the molten metal can be adjusted evenly, the temperature of the solution is uniform, and local high temperatures will not occur. Metal burning loss is less, which is more important for smelting rare metals.

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

Second, this type of furnace does not require the necessary preheating process of coal furnaces, gas furnaces and resistance furnaces. It is easy to use and simple to operate. It can work continuously for a long time and can be started or stopped at any time as needed. It can be fully manual or fully automatic. Or semi-automatic work, you can have an absolute advantage in production scheduling.

Third, there is no need to heat the workpiece as a whole, and local heating can be selected. Therefore, the power consumption is small, the workpiece deformation is small and the heating speed is fast. The workpiece can reach the required temperature in a very short time, thereby oxidizing and decarburizing the workpiece surface. Once the heating defects are reduced to a very low level, it can be used for heating or heat treatment of steel, tungsten, molybdenum and other steel materials. It can also be used for the heating or heat treatment of aluminum, titanium, zirconium and niobium with strong chemical activity.

Fourth, induction heating equipment can be installed on the production line, making it easy to automate and mechanize the production line and facilitate management. It can effectively reduce transportation, save manpower, and improve production efficiency.

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

Based on the above advantages, today, when electric energy is gradually becoming the dominant energy source in the field of heating instead of non-renewable energy sources such as coal, oil, and gas, induction heating is increasingly widely used in fields such as smelting and heating. The applications of electric heating, especially induction heating, include With a very wide range of application prospects, induction heating equipment manufacturers have broad room for development.
