Induction heating of metal parts for the assembly of mechanical elements such as bearings, gears, pulleys, etc., is the most common method of heating. most current technological approach which leaves behind inefficient and sometimes harmful systems, such as direct flaming with a blowtorch, hot oil baths, sand furnaces, etc. For this purpose, the induction heaters.
On many occasions, with the old methods, we do not achieve the desired objective because the heating is neither uniform nor controlled. In addition, they can produce excessive heat, even irreparable damage to the element in question, reducing its useful life.
With the use of induction heaters we avoid applying excess heat. as they allow us to apply controlled and uniform heat throughout the part, avoiding damage to the element and to the lubricants that this element usually contains.
Other important advantages are the reduction of occupational accidentsThe main reason for this is that no dangerous tools such as acetylene torches or hot oils are used, and the environmental care as no vapor or toxic residue is produced.
How does an induction heater work?
On the one hand, the heaters are equipped with a generally "U" shaped piece in contact with an electric coil in charge of generating the necessary current (low frequency). On the other hand, they also have a metal piece called "Yugo". which serves to close the electrical circuit.
All units have a display that indicates the exact temperature of the part at all times and a sensor that measures it. When the part reaches the maximum heating temperature, which is usually around 120º-130º, it stops applying heat, and when the sensor appreciates that the part has cooled down to 80º-90º, it turns on again, thus keeping the part hot and optimizing electricity consumption without damaging it.
With this system, we only heat the part and not the surrounding air. In this way, we save the energy costs involved.
At Epidor Technical Distribution we have different types of induction heaters:
- Portable models.
- Models fixed on bench.
- Custom-made models according to customer's requirements.
- Medium frequency models for larger assemblies and disassemblies.
Advantages of using an induction heater
- Safety first!
- They are environmentally friendly as they do not emit fumes, flames, vapors or oil leaks.
- Good alternative to reduce consumption.
- Controlled and localized heating.
- Maximum demagnetization < 2 A/cm.
- Valid for sealed and prelubricated bearings.
- Automatic reheating mode.
- CE marking.
At Epidor Technical Distribution we care about our customers. For this reason, we surround ourselves with the best brands in the market such as Bega-BetexWe offer you the best products and find the solution to your problems.
