4. Flame hardening is similar to induction hardening, in that it is a surface hardening process. Induction Heat Treating – Zone Hardening and Scanning. Induction hardening is widely used process for the surface hardening of steel. Normally, medium-carbon steels (0.35-0.5% carbon), with or without alloying additions, are used to ensure a satisfactory hardening response, final choice depending on required surface hardness and core properties. The following will show some of the advantages and disadvantages of induction heat treatment. The Induction Hardening Job Work coil can be designed to accommodate any geometric shape that will allow access to the contour to be heat treated and quenched accordingly. For the mass production of components in medium or large quantities however, induction hardening offers a range of benefits: With a suitable hardening machine, induction hardening can be fully integrated in the cycle of the production line and automated. Not only ensuring cooking performance, the kitchen also brings high safety for users as well as saves costs. A large number of steels could be flame-hardened. 3. On weighing the pros and cons of both heat hardening methods, the induction technique is the in-line but scalable winner. Induction hardening can be easily automated and is suitable for complex geometries, especially in mass production! Both methods, case hardening and induction hardening, have advantages and downsides. Flame hardening can be done of any shape, like flat, circular, irregular shapes, etc. Advantages and Disadvantages of Induction-Hardening of Steels: a. Tempering is a low temperature (below A1) heat treatment process normally performed after neutral hardening, double hardening, atmospheric carburising, carbonitriding or induction hardening in order to reach a desired hardness/toughness ratio. • But the disadvantages of these system is they generate a heat • To avoid this heat generate used laminated cores and other methods to minimize the effects • Engineers at Midvale Steel and The Ohio Crankshaft Company drew on this knowledge to develop the first surface hardening induction heating systems using motor generators. Advantages. Case hardening solutions, meanwhile, work best on larger, less geometrically detailed components, especially when they require the speed that comes with a batch processing production run. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The process is simple. 3. Localized areas can be heat treated; Very short surface heat-up times Induction Motor Disadvantages: Some of the disadvantages of induction motors compared to dc motors and synchronous motors are: 3 phase induction motors have poor starting torque and high have in rush currents. Tempering. To practice single shot hardening, a lot of power supply is required. An expensive grinding process is to be adopted after nitriding due to the formation of a thin layer which is in white color. There are disadvantages with the single shot approach. The Induction Hardening Job Work coil can be designed to accommodate any geometric shape that will allow access to the contour to be heat treated and quenched accordingly. For example, the equipment is relatively complicated, the cost of inputting at a time is relatively high, and the inductive components (induction coils) are poorly interchangeable and adaptable, and are not suitable for application on some complicated shapes. PRINCIPLE When the metallic workpiece (usually steel) is placed in a coil and current is flown In the coil then current is induced on the surface of the metallic workpiece and it is heated upto above its critical temperature. So the motor is not suitable for high power applications like traction systems etc. Even though there are a few drawbacks, you can overcome them. In many ways, flame hardening is similar to induction hardening. Disadvantages: Greater forces are required Advantages and Disadvantages of Flame-Hardening: 1. Induction cookers are gradually conquering the needs of many families because of its great use. Electromagnetic induction heating disadvantages: No product is perfect, it also has some shortcomings. Advantages and disadvantages of induction heating technology United Induction Heating Machine Limited We are experienced in Induction Heating,induction heating machine,Induction Heating equipment.They are widely used in induction heating service, induction heat treatment, induction brazing, induction hardening,induction welding, induction We design, build and repair high quality general purpose and fully automated induction generators, process development, and personalized consulting for each and every one of our clients. After conducting this specific process, the metal part is intended to undergo a martensitic formation, allowing it to obtain features and properties that it does not possess before. When you turn on an induction cooktop, a magnetic field underneath the surface is activated. It works best on crankshafts and on gear teeth as a localized solution. Principles of Induction Hardening and Inspection / 59. hysteresis energy losses. Depth of hardness is less. Are you looking for support or purchase information, please contact us here The following will show some of the advantages and disadvantages of induction heat treatment. Zone Induction Hardening: The beauty of induction heating is that you can localize the heat by positioning the induction coil right at the part of the workpiece, or zone, that you wish to heat treat without affecting the rest of the workpiece area. Hardening is a process of heating followed by cooling generally fast for increase hardness and mechanical strength of steel. Hardening. Heat is applied to the part being hardened, using an oxy- acetylene (or similar gas) flame on the surface of the steel being hardened and heating the surface above the upper critical temperature before quenching the steel in a spray of water. 1. The process cannot be applied for all the alloy steels. The disadvantage is that capital and set up costs are high. The shaft is the same dimensions as example 1 (30 x 500 mm). During cold working the part undergoes work hardening and the microstructure deforms to follow the contours of the part surface. As a result, they draw inrush currents causing momentary voltage drop. The advantage of induction hardening is that the process is quick, efficient and surface degradation is minimal. Induction hardening can be applied to a wide range of steels and cast irons. b.
