100KW High Frequency Metal Hardening Furnace
What is 100KW High Frequency Metal Hardening Furnace Advantage
The workpiece is heat treated in a metal hardening furnace. The left and right sides are to adjust the characteristics of metal materials and adjust the mechanical properties, strength, hardness, plasticity, toughness and fatigue strength of the high frequency metal hardening furnace. According to the sequence of the whole process, it can be divided into preliminary heat treatment and final heat treatment. Heat treatment and preheat treatment are mainly to improve the cutting performance of materials, such as increasing the hardness of low carbon steel through normalizing, and reducing the hardness of high carbon steel through spheroidization. The final heat treatment is to achieve the required mechanical properties of the parts. After the parts are made, they are quenched in an induction furnace and tempered at a medium temperature.
This problem may also be caused by relatively low insulation resistance or furnace short circuit. For induction heating equipment, we need to use a megohmmeter to detect the resistance of the furnace and eliminate the short-circuit points in the furnace. Then, since the resistance of the steel and the induction coil is low, the overcurrent is maintained. A megohmmeter must be used to detect the resistance of the furnace relative to the induction coil. If the resistance is too low, the furnace needs to be built from the beginning.
The high frequency metal hardening furnace has a deeper depth, higher hardness and better wear resistance than the laser hardened layer. The disadvantage of this technology is that it destroys the surface roughness of the workpiece to a certain extent, and usually requires subsequent machining to Recovery to reduce the surface roughness of the parts after laser melting treatment and reduce the subsequent processing volume. In the melting furnace, the induction high frequency heating machine produces a special laser melting and quenching coating, which can greatly reduce the surface roughness of the fusion layer.
At present, metallurgical work rolls, guide rails and other workpieces of various materials are all processed by laser melting. Now, the surface roughness is close to the level of laser hardening. High frequency metal hardening furnace tools have been successfully applied to surface strengthening of vulnerable parts in metallurgy, machining and petrochemical industries. Especially for the service life of wearing parts such as front wheels, guide rails, gears, cutting edges, etc., the effect is remarkable, and huge economic and social benefits have been achieved.If you need, please contact us with [email protected].

How exactly does metal hardening furnace work?
Through the conversion of the high frequency metal hardening furnace, the 50HZ/60HZ alternating current is converted into a direct current voltage, and then the direct current is converted into a 20-40KHZ high-frequency voltage output through the control circuit. The fast-moving high-voltage current will produce high-speed changes in the cable. After the magnetic field cable is in contact with the iron container, the surface of the container will cut off the AC magnetic lines of force and generate alternating current on the metal part at the bottom of the container. The vortex causes the iron atoms at the bottom of the container to move irregularly at high speed.
Induction heating is to generate current eddy currents in the inductor coil through alternating current, so that the electron holes in the magnetically conductive objects in the coil move to generate heat. High-frequency induction heating equipment can instantly heat metal objects to any desired temperature, including its melting point.
The high frequency metal hardening furnace tool is composed of bed, loading and unloading mechanism, clamping and rotating mechanism, quenching transformer and resonance tank circuit, cooling system, quenching liquid circulation system, electrical control system, etc. Two main types: vertical and horizontal. The induction hardening process is mainly realized by the cooperation of the hardening machine tool and the medium and high frequency power supply. It is used for various gears, bearings, shaft parts, valves, cylinder liners and various machinery. The parts are quenched and heat treated.
Metal Hardening Furnace
The hardening heat treatment process uses heat to increase the hardness of the material surface, thereby reducing its fragility. Hardening results in a strong shell and a strong core
The use of this Metal Hardening Furnace will lead to an improvement in mechanical properties and an increase in the level of hardness, thereby producing tougher and more durable items. The alloy is heated to exceed the critical transition temperature of the material, and then rapidly cooled enough to transform the soft starting material into a harder, stronger structure. Depending on the amount of alloying elements in the material, the alloy can be cooled by air or by quenching in oil, water or other liquids. Usually, the hardened material is tempered or stress relieved to improve its dimensional stability and toughness.
Steel parts usually require heat treatment to obtain improved mechanical properties, such as increased hardness or strength. The hardening process involves heating the component above the critical (normalizing) temperature, holding it for one hour per inch of thickness at this temperature, cooling it fast enough to transform the material into a harder, stronger structure, and then tempering. Steel is essentially an alloy of iron and carbon. Other steel alloys have other metal elements in the solution. Heating the material above the critical temperature will cause carbon and other elements to enter the solid solution. Quenching “freezes” the microstructure and creates stress. The parts are then tempered to change the structure, achieve the appropriate hardness and relieve stress.
What is hardening heat treatment?
Hardening heat treatments invariably involve heating to a sufficiently high temperature to dissolve solute-rich precipitates. The metal is then rapidly cooled to avoid reprecipitation; often this is done by quenching in water or oil. Precipitation hardening is used to produce most high-strength alloys.
What does hardening do to steel?
Hardening is a metallurgical metalworking process used to increase the hardness of a metal. The hardness of a metal is directly proportional to the uniaxial yield stress at the location of the imposed strain. A harder metal will have a higher resistance to plastic deformation than a less hard metal.
What are the types of hardening?
Some common types of hardening include strain hardening, solid solution strengthening, precipitation hardening, and quenching and tempering.
What the difference between hardening and tempering?
The main difference between annealing hardening and tempering is that annealing is done to soften a metal or an alloy and hardening is done to increase the hardness of a metal or alloy whereas tempering is done to reduce the brittleness of quenched metal or alloy.
Among the metals, those with high melting point are relatively large in power, and those with low melting point are relatively small; those with low resistivity are more powerful, and those with high resistivity are less power.
he shape of the welded parts of the high-frequency high frequency heating machine is almost unlimited, the outline pattern will not be damaged, the external crystal layout of the metal remains unchanged, the annealing range is small, and it is widely used in the metal glasses manufacturing industry without welding scars. High-frequency quenching uses high-frequency current to locally heat and cool the surface of the workpiece to obtain a surface hardened layer.
