Our sophisticated training concept gives you the opportunity to have your eldec system operators comprehensively trained. Induction hardening and heat treating are ideal for a wide variety of applications in the transportation, aerospace, and energy industries, for processes such â¦ Home » Applications » Metal industry » Induction hardening. Hardening is a process of heating followed by cooling generally fast for increase hardness and mechanical strength of steel. Carbon steâ¦ Induction hardening is a process in which the heat is generated directly in the workpiece. This minimizes deformities in the workpiece and ensures the efficiency of the process. Induction hardening is used to strengthen a specific area of a part. %PDF-1.5 %âãÏÓ used in induction hardening are SAE 4140, 4150, 4340, 5150, 5140, and 52100. Hardening is the process of heating the material above 900°C temperature followed by quenching. A number of applications and items can benefit from the heat treatment hardening process described above. Shafts, gears, armatures, sprockets and other components can all be hardened using this induction process. Induction Hardening Applications Include. Case hardening the surface of steel increases the wear resistance of the component without reducing the ductility of the bulk of the material. Induction hardening Treatment is favored for parts that are subject to heavy loading. Higher frequencies produce thinner skins. The resultant hardened area improves the wear and fatigue resistances along with strength characteristics. Ideal hardening results can only be achieved by perfectly matching a precisely controlled energy source with an optimum inductor design. Hardening crankshafts involves consideration of 4 different heating zones - pins, journals, flanges, and shaft - with unique characteristics. When placing a product in that field, an electric voltage is produced which results in an opposite alternating current. This application is perfect for the process of manufacturing cogs and gears. Description. This magnetic field produces eddy currents in the metal, which heat the workpiece up to the desired temperature. Radyne Induction Heating Systems match your mill speed, require minimal maintenance, provide uniform metallurgical quality, and are built for a range of applications from coating and heat treatment. The surface of this 1055 steel shaft is â¦ After the induction hardening process is achieved, the metal workpiece needs to be quenched in water, oil or air inorder to obtain specific properties of the surface layer. Even though the top and bottom of the gear teeth are at different distances from the inductor, a smooth and precise hardness layer can be achieved. Induction hardening In inductive hardening or induction hardening, an alternating current is driven through a coil-shaped conductor, thereby creating a magnetic field. There are two mechanisms of energy absorption: generation of close-loop (eddy) currents inside the body which cause heating due to electrical resistance of the body material Multi power: Plug-in expandable energy source for precise integration into systems (MF 5 – 30 kW). We also have metallurgical sectioning ability to test accurately hardened depths and extents. Induction hardening, using induction heating and quenching, provides an economical way to process shafts, gears, bearings, yokes, spindles, sprockets, wire, tube, pipe or other parts. Frequently, steel and stainless steel components require induction hardening to provide optimum performance and long service. With a conventional method (or if we induction hardened the entire length for that matter), there would be significantly more warpage. This cools the metal until martensitic transformation occurs, producing a hardened surface that is tougher than the base metal. The sky is the limit: Customized energy sources with single or multiple outputs and a wealth of power and frequency combinations (LF, MF, HF, DFG, SDF 20 – 3000 kW). One or many induction coils are used to generate and target an alternating magnetic field. Gearbox and Hydraulic Valve Parts. One or many induction coils are used to generate and target an alternating magnetic field. With the precision frequency adjustment, even the most demanding jobs can be completed with ease. Induction hardening offers significant advantages over traditional methods for heat-treating steel, alloy, and other metal parts. Induction hardening is a form of heat treating where a metal part is heated by induction and then quenched. The hardening depth in the workpiece is controlled, very precisely, by adjusting the electrical power output of the induction machine and the frequency of the inductor / coil current. The primary application of this induction method is the hardening of steel. Induction Hardening Applications The heat treating hardening process is utilized in various industries, including transportation, aerospace, and energy. Induction Heating Applications RDO Induction's mission is to provide our customers with superior products and support for a variety of induction heating applications. Typical applications include axles, saw blades, shafts, stampings, spindles, gears and most symmetrical parts. The modular ELO-INDIVIDUAL system solution is designed for cost-efficient induction applications with shorter cycle times, a high degree of integration, frequently switching hardening tasks and special solutions. This guarantees the component is heated at a consistent temperature across the entire part to ensure even surface hardness. All in one: Mobile energy sources with integrated active cooler and intuitive touchscreen operation (MF and HF 20 – 70 kW). Typical applications of induction hardening include gears, shafts, axles, cam lobes, stampings, and spindles, mostly symmetrical parts. Induction hardening, by contrast, offers extremely short heating times. Induction hardening, using induction heating and quenching, provides an economical way to process shafts, gears, bearings, yokes, â¦ Immediately after heating, the component then goes through a quenching process using water, oil, or an emulsion. It is a very effective and attractive method in the manufacturing of steel shafts, components, and other metal parts across a range of industries. The induction hardening is a heat treatment for surface hardening, mainly used for complicated shaped workpieces or for partially hardening of specific parts of an item. In magnetic materials, further heat is generated below the curie point due to hysteresislosses. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I R losses in the material. eldec offers energy sources with the latest converter technology in three frequency ranges: With Simultaneous Dual Frequency, also known as SDF, eldec offers an additional method that is used especially for workpieces with complex shapes.
