Induktiolämmittimet

Induktiolämmittimet, also known as induction heaters, are devices that use electromagnetic induction to heat conductive materials. The principle behind induction heating involves generating an alternating magnetic field, which then induces eddy currents within the workpiece. These eddy currents, due to the electrical resistance of the material, generate heat through a process called Joule heating. The effectiveness of induction heating depends on factors such as the frequency of the alternating current, the conductivity and permeability of the material being heated, and the geometry of the workpiece and the induction coil.

Induction heating offers several advantages, including rapid and precise heating, energy efficiency as heat is generated directly within the material, and minimal environmental impact due to the absence of combustion. It is a non-contact heating method, which can prevent contamination of the workpiece. Applications for inductiolämmittimet are widespread across various industries. They are commonly used in metalworking for processes such as hardening, tempering, annealing, brazing, soldering, and melting. In the automotive industry, they are employed for heat-treating components like crankshafts and gears. Induction heating is also utilized in manufacturing for processes like forging and in laboratories for specialized heating applications.
