Description

Rail high frequency induction hardening machine

Induction hardening is used in particular for the hardening/quenching of bearing surfaces and shafts as well as intricately shaped parts where only a specific area needs to be heated.

Through the choice of the operating frequency of the induction heating system, the resulting depth of penetration is defined.

Additionally, it can be decided if the area is to be hardened in the air, with water or with a special hardening emulsion. Depending on the cooling medium, different degrees of hardness are achieved.

 Induction hardening can be realized as a manual or automated solution. There is also the possibility to harden in a continuous process.

• Suitable for hardening and tempering of various workpieces, such as induction hardening of shafts, gears, guide rails, discs, pins, and other parts;
• It has the functions of continuous hardening, simultaneous hardening, segmented continuous hardening, and segmented simultaneous hardening;
• Use numerical control system or PLC and frequency conversion speed regulation system to realize workpiece positioning and scanning, and connect PLC and induction heating power supply to realize fully automated production.
• Vertical (hardening of shaft parts) + horizontal (hardening of gear ring parts)

Hardening is one of HLQ induction heating power systems’s main application areas. Hundreds of our hardening solutions are at work around the world—many of them within the automotive industry.

The main benefit of induction heating for hardening is that it takes just a few seconds. In a furnace, the same process can take hours or even days. How is that possible?

The answer is that induction is phenomenal at generating heat fast. This, in turn, means you can integrate hardening in the production process. Hardening in a furnace, on the other hand, is more time-consuming (greater heat loss) and requires moving the components either to your own furnace or to that of a subcontractor.

In-line integration of hardening reduces your lead times considerably.

You get full control over quality, delivery times and costs. There’s no need to transport kilos of components back and forward, which saves energy and the environment.And last but not least, you cut down the amount of administration to a minimum.

HLQ Induction Heating Power Systems has many years of experience in inductive hardening and tempering of diverse workpieces. At the heart of each Hardening system is HLQ Induction Heating Power Systems Induction Heat Power Source, the industry’s most advanced induction frequency converter. These acclaimed converters help ensure optimum hardening results—day in day out, year after year

The induction hardening machine includes Vertical Scanning , Horizontal (centerless) Scanning and customized machines—and serial and/or parallel compensated induction power sources with a wide range of output power and frequencies.
