The advantage of induction hardening is that the process is quick, efficient and surface degradation is minimal. 2. Disadvantages: Greater forces are required Induction cookers have many advantages over electric stoves such as energy savings, cooking speed, and cleaning simplicity; however, they do have a few potential disadvantages. Induction hardening is a type of heat-treating process that typically subjects a metal part under induction heating and quenching. Advantages. 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 Induction hardening is widely used process for the surface hardening of steel. Tempering. b. Localized areas can be heat treated; Very short surface heat-up times Induction hardening … The following will show some of the advantages and disadvantages of induction heat treatment. Compared with flame hardening, induction heating equipment is more complex, and adaptability to poor, difficult to guarantee the quality of some of the complex shape of the workpiece. 3. Scaling and hardening distortion are less than with flame hardening! Advantages & Disadvantages Of Induction Cooktops Induction cooktops are very different from all the other cooktops in the market, as they directly heat the pan and not the hob ring. During cold working the part undergoes work hardening and the microstructure deforms to follow the contours of the part surface. The induction heating heat treatment also has some drawbacks or disadvantages. DUOLIN induction heaters can precisely meet your specific needs of induction heating, induction forging, induction brazing, induction hardening, induction annealing, induction tempering, and hot pipe … advantages and disadvantages of the different surface hardening processes. Even though there are a few drawbacks, you can overcome them. Flame Hardening. The decision which hardening process is advantageous for a specific workpiece can be taken by the processing company only and, in case of doubt, after having consulted experts for such processes. The answer is: induction hardening. Induction hardening can be applied to a wide range of steels and cast irons. 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. In many ways, flame hardening is similar to induction hardening. The classical hardening method is case-hardening, where the complete workpiece has to be heated for hours to reach the desired hardness. But that doesn't mean the induction hob is completely good, it also has disadvantages that users need to pay attention to. • 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. 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. Hardening is a process of heating followed by cooling generally fast for increase hardness and mechanical strength of steel. Induction cooktops and ranges cook faster than regular electric ranges, but you’ll have to make some adjustments to use them. 2. Flame hardening can not be applied as precisely as other case hardening processes, such as induction hardening or boronizing. The process cannot be applied for all the alloy steels. Some of the disadvantages of case hardening process are . Not only ensuring cooking performance, the kitchen also brings high safety for users as well as saves costs. An expensive grinding process is to be adopted after nitriding due to the formation of a thin layer which is in white color. Advantages and Disadvantages of Induction-Hardening of Steels: a. The following will show some of the advantages and disadvantages of induction heat treatment. The Difference Between Flame Hardening and Induction Hardening. 1. The disadvantage is that capital and set up costs are high. Example 2: Induction Hardening of Quenched-and-Tempered Steel (42CrMo4) The case-hardening depth is approximately 2 mm and the hardness is 57-62 HRC by single-shot hardening. 7. As a result, they draw inrush currents causing momentary voltage drop. Both methods, case hardening and induction hardening, have advantages and downsides. It helps to obtain selective localised hardening without effecting the core or other sections of the part, and the properties. Laser-beam hardening (laser hardening) offers even shorter heating times of the surface than in induction hardening. An old-fashioned, but still useful, explanation of the hysteresis loss states that it is caused by friction between mole-cules when the material is magnetized first in one direction and then in the other (Ref 4). The process is simple. Hardening. 4. some common surface hardening techniques • induction hardening • flame hardening • laser beam hardening • electron beam hardening 4. Principles of Induction Hardening and Inspection / 59. hysteresis energy losses. 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 workpiece weight is also the same, and the 8-ton load corresponds to 2,667 shafts. Unlike hot working, the inclusions and grains distort to follow the contour of the surface, resulting in anisotropic engineering properties. 4. 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. 6. On weighing the pros and cons of both heat hardening methods, the induction technique is the in-line but scalable winner. The rapid heating drastically reduces the heating time to increase productivity of the heat treatment section. Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. So the motor is not suitable for high power applications like traction systems etc. More and more companies are opting for induction-based hardening solutions. 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. Depth of hardness is less. 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. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. This kind of hardening has its disadvantages, especially when it comes to the mass production of gears. It works best on crankshafts and on gear teeth as a localized solution. 3. Source: Abstracted from Handbook of Engineering Materials, 5 th Edition. Induction hardening can be easily automated and is suitable for complex geometries, especially in mass production! 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. Induction cookers are gradually conquering the needs of many families because of its great use.
