A rapid hot press system in which the heat is supplied by RF induction to rapidly consolidate thermoelectric materials is described. Use of RF induction heating enables rapid heating and consolidation of powdered materials over a wide temperature range. Such rapid consolidation in nanomaterials is typically performed by spark plasma sintering (SPS) which can be much more expensive. Details of t...

More rapid increases in the pH value and hardness during electromagnetic heating of a pan of water were observed than when the pan was heated by LNG or LPG. The water quality changed universally in several tap water samples across Japan. This quality change was closely correlated with the rate of temperature increase, irrespective of heating by electromagnetic induction, LNG or LPG.

An idea of transverse flux induction heating has been well known for more than sixty years. Some of its main principles were presented for instance by Russian physicist Volovgin (Mühlbauer, 2008). Many papers on the topic considering mainly theoretical aspects of the task were published in the last sixty years (Baker, 1950), (Jackson, 1972), (Barglik, 1992), (Mühlbauer et al, 1995), (Tudorache ...

OBJECTIVE To determine the heating characteristics of needle-shaped duplex stainless steel thermoseeds, and to evaluate their effectiveness in the induction of hyperthermia in rabbit liver. MATERIALS AND METHODS Thermoseeds of the two different shapes, L-shaped for single doses of hyperthermia and I-shaped for in-vitro study and repeated hyperthermic induction, were prepared. For the in-vitro...

Induction heating is a typical application field for high-frequency power supplies whose operating frequencies range from one to several hundred kilohertz. Induction heating applies an alternating magnetic field generated from the current flow in a coil to the conductive matter to be heated. This induces eddy currents on the conductive matter, those currents generate joule loss due to the matte...

The characteristics of steels during electroplating or induction heating are very complex. Induction heat-treating of steel has become increasingly important as a means of reducing cost and improving the quality of carbon steel components. The use of high frequency (40 to 2OOkHz) offers many advantages, but tooling and cycle optimization is complex and time consuming. Approximate analytical met...

All-surface induction heating systems, typically comprising small-area coils, face a major challenge in detecting the presence of a metallic vessel and identifying its partial surface coverage over the coils to determine which of the coils to power up. The difficulty arises due to the fact that the user can heat vessels made of a wide variety of metals (and their alloys). To address this proble...

The paper presents the human blood reheating technique for medical purposes with high frequency induction heating system. The temperature is analyzed to determine the heat distribution in different positions of human blood within the non metallic tank. In the proposed induction heating system, the inductive applicator is a primary working coil of the modified half bridge high frequency inverter...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 Blackbody sources with nearly unity emittance that are in equilibrium with a pure freezing metal such as gold, silver, or copper are used as primary standard sources in the International Temperature Scale of 1990 (ITS-90). Recently, a facility using radio-frequency induction heating for melting and filling the blackbody...
