Hardening is heat treatment of metal, necessary to impart special characteristics to a workpiece or product. This operation allows you to increase strength, increase elasticity, improve the properties of the material - after the procedure, the product can be used where serious loads occur. When hardening, the metal is heated to a critical temperature, during this process the type of crystal lattice changes, followed by sharp cooling using various coolants - liquid, solid or air.
There is also a more modern method of heat treatment - hardening with high currents frequency (High Frequency), at which an electromagnetic field is formed around the workpiece, the currents heat the metal to a certain temperature, then it cools sharply. This method is more advanced than the “classical” one and has a number of advantages over it.
- Surface hardening - unlike other methods, when processing with high frequency currents it is possible to carry out only surface hardening , when the middle part of the workpiece remains soft and retains its properties, and the upper layers are hard and durable.
- High speed - high-frequency hardening allows you to heat the metal much faster than with other methods, which is especially important for large orders for large companies. The process of manufacturing products, when both thermal and mechanical processing of metals occurs in one production facility, is significantly accelerated .
- Selective exposure - modern equipment makes it possible to accurately determine the depth and area of hardening, due to which the quality of the finished product is consistently higher.
- High efficiency – with high-frequency hardening, this figure reaches 93%.
- Automation of production when using modern methods of metal processing guarantees the accuracy and manufacturability of the processes.
Areas of application of hardening with high-frequency currents
Products obtained as a result of this processing method perfectly resist increased loads and have a good margin of safety and wear resistance.
Hardening with high-frequency currents is actively used in the manufacture of parts for car transmissions - gears, shafts and other components, suspension - levers, supports, etc.
In addition, the method allows the production of strong and durable elements for many other areas - equipment production, mechanical engineering, construction and other areas.
