Features of medium frequency induction furnace
The medium frequency induction furnace is an induction heating device that uses the principle of electromagnetic induction to heat metal. The current passes through the inductor coil to generate a magnetic field. The metal in the magnetic field cuts the coil and generates eddy current, which heats the metal itself. It is widely used in pre-forging heating and steel bar quenching and tempering. Heating and metal smelting.
The application of medium frequency induction furnace in different industries has derived different names. For example, pre-forging heating is generally called medium frequency heating furnace, heating furnace or diathermic furnace; smelting casting is generally called medium frequency melting furnace, melting furnace or one-to-two melting furnace, etc.; The medium induction furnace is generally also called medium frequency furnace or medium frequency electric furnace, but no matter what it is called, the heating principle is the same, the basic structure is similar, and the characteristics are also the same.
The environmental protection characteristics of the medium frequency induction furnace are more obvious, and it is particularly popular among users in the current environmental protection storm. The medium frequency induction furnace has a superior working environment, improves the labor environment of workers and the company’s image, is pollution-free and has low energy consumption. Compared with coal stoves, medium frequency induction furnaces will no longer be bake and smoked by coal stoves under the scorching sun, and can meet the requirements of various indicators 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. .
The energy-saving characteristics of the medium frequency induction furnace are manifested in the fast heating speed, high production efficiency, less oxidation and decarburization, saving materials and forging die costs. Because the principle of medium frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself, and ordinary workers use medium frequency electric furnaces. The continuous work of the forging task can be carried out ten minutes after work, without the need for professional furnace burning workers to perform furnace burning and sealing work in advance. There is no need to worry about the waste of heated billets in the coal furnace caused by power outages or equipment failures. The key is that the burning loss of metal materials is less, the raw materials are saved, and the utilization rate of the materials is improved.
The medium frequency induction furnace has good heating temperature uniformity and high temperature control accuracy. The heat of induction heating is generated in the workpiece itself, so the heating is uniform and the temperature difference is extremely small. The application of temperature control system can achieve precise control of temperature and improve product quality and qualification rate.
The medium frequency induction furnace is suitable for automated production lines and is currently the first choice for heating equipment in intelligent factories. The medium frequency induction furnace is equipped with an automatic feeding system. Temperature measurement system, conveying system, cooling system and temperature three sorting can realize unattended operation in the true sense. The heating device of medium frequency induction furnace has the advantages of flexible operation, convenient installation, excellent thermal processing quality and favorable environment, and is rapidly being eliminated Coal-fired furnaces, gas furnaces, oil-fired furnaces and ordinary resistance furnaces are a new generation of metal induction heating equipment. The medium frequency induction furnace is the main equipment of the foundry, forging and heat treatment workshop. The stability, reliability and safety of its work are the guarantee for the normal and stable operation of the casting, forging and heat treatment production line of the flow-through operation.
