What is 120KW High Frequency Heating Machine Advantages?

 

The 120KW high frequency heating machine does not need to heat the workpiece as a whole, but can selectively heat the parts, so as to achieve the purpose of reducing power consumption, and the deformation of the workpiece is not obvious. The fast heating speed can make the workpiece reach the required temperature in a short time or even within 1 second. As a result, the surface oxidation and decarburization of the workpiece is relatively small, and most workpieces do not require gas protection.

 

The high frequency heating machine can adjust the surface hardening layer by adjusting the working frequency and power of the equipment as needed. As a result, the hardness, strength and toughness of the hardened layer are relatively high. After the heat treatment by the induction heating method, the toughness area of ​​the workpiece under the surface hard layer becomes thicker, and the compressive internal stress is also improved, thereby making the workpiece more resistant to fatigue and fracture. The induction heating machine is easy to install on the production line, easy to realize mechanization and automation, easy to manage, and can effectively reduce transportation, save manpower, and improve production efficiency.

 

The induction heating machine can realize multiple purposes on one machine. It can complete the heat treatment process, such as quenching, tempering, welding, smelting, thermal assembly, thermal disassembly and thermal forming, easy to operate, and can be started or stopped at any time. And no preheating is required. It can be operated manually, semi-automatically and fully automatically; it can work continuously for a long time, or it can be used randomly when in use. Conducive to the use of equipment during the low electricity price discount period.

 

The induction heating machine advocated by the state has high electric energy utilization, environmental protection and energy saving, safety and reliability, and good working conditions for workers.

 Heating machine offers a controllable and localized method of heat without contact to the parts (components) being heated. The heat is generated by inducing an alternating magnetic field into electrically conductive materials. Induction Heating Machine is very low cost to run and normally creates significant costs savings versus other traditional process heating technologies.

The  high frequency induction heating machine‘s large current flows to the heating coil that is wound into a ring or other shape. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil.

When the heated object such as metal is placed in the coil, the magnetic beam will penetrate the entire heated object, and the inside of the heated object will be generated in the opposite direction to the heating current. The corresponding large eddy current. Due to the resistance in the heated object, a lot of Joule heat will be generated and the temperature of the object will rise rapidly. To achieve the purpose of heating all metal materials.

The 120kw high frequency heating machine puts the workpiece into the inductor, and when an alternating current of a certain frequency is passed through the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field produces a closed induced current in the workpiece.

The distribution of the induced current on the cross-section of the workpiece is very uneven, and the current density on the surface of the workpiece is very high and gradually decreases inward. This phenomenon is called the skin effect. The electric energy of the high-density current on the surface of the workpiece is converted into heat energy, and the temperature of the surface is increased, that is, surface heating is realized. The higher the current frequency, the greater the current density difference between the surface and the interior of the workpiece, and the thinner the heating layer. After the temperature of the heating layer exceeds the critical point temperature of the steel, it is rapidly cooled to achieve surface quenching.

When high frequency (HF) current is used for induction, even welding is possible. In this application, using HF current can reach a very shallow electrical reference depth. In this case, the metal belt is continuously formed and then passed through a set of precisely designed rollers whose sole purpose is to press the edges of the formed belt together and weld it. Before the formed strip reaches the roll set, it passes through the induction coil. In this case, the current flows down the geometric “V-shaped” flow created by the strip edges, rather than around the outside of the formed channel. When the current flows along the edges of the strip, they will be heated to the proper welding temperature (below the melting temperature of the material). When the edges are pressed together, all debris, oxides and other impurities are pressed out to form a solid forged weld.

What is the purpose of induction heating machine?

The induction heating machines of an electromagnet and an electronic oscillator. The electronic oscillator passes high frequency alternating current through the electromagnet. The rapidly alternating magnetic field penetrates the object and generates current in the conductor, which is called eddy current. Induction heating is used in various applications in domestic and commercial cooking, such as heat treatment, brazing, welding preheating, melting, shrink assembly, sealing, brazing, curing, and research and development.

 

How does frequency affect induction heating?

Low frequency induction heating has a deeper skin effect which is more efficient for larger parts. As a rule, heating smaller parts with induction requires higher operating frequencies (often greater than 50 kHz), and larger parts are more efficiently heated with lower operating frequencies.

 

Are there any metal materials that the high frequency heating machine cannot perform heat treatment?

Metal heat treatment can be said to be inseparable from high frequency heating machine. High frequency heating heat treatment can be used to heat various metal workpieces locally or as a whole, such as round bars, steel plates, drill rods, drill rods, bolts, nuts, etc. Pieces, fasteners. Round steel, square steel. High frequency induction heating heat treatment can also be used for various metal workpieces, such as gears and sprockets. Round steel, steel plate, guide rail, spline shaft, gear shaft and other shafts are quenched and heat treated. There are also good quenching effects on screwdrivers, hammers, axes, rollers, train wheels, etc., easy to use, high efficiency and energy saving. In addition, high-frequency induction heating can also be used for annealing and heat treatment of various metal workpieces, such as stainless steel, stainless steel pipe, round steel, and steel strip. Ribbed steel bars, steel bars, iron wires, steel wires, etc.We cannot rule out that some metals such as aluminum and aluminum alloy workpieces or products use high-frequency induction heating. The effect is sometimes not ideal, because aluminum has low magnetism and heat dissipation is too fast, which prevents the workpiece from collecting heat well.
