In this study; iron based powder metal (PM) bushing compacts were sintered via medium frequency induction heating system. Iron based powders were mixed with 2 wt.% copper (Cu), 0.3 wt.% carbon (C) and 1 wt.% zinc stearat (Zn-st) via V-Type mixer. PM compacts were sintered by 2 different sintering processes. One of them was conventional sintering method other was medium frequency induction sinte...

The paper proposes an Induction Heating Principle using Full Bridge Inverter where a Single phase full bridge inverter consists of one rectifier, one capacitor, four mosfets and at the load side one induction heating rod is connected. So by this when any ac supply is given to the input side, we will get the square wave at the output side[1][3]. In this concept the induction heating rod is heate...

To develop a novel ablation therapy for human solid cancer, the heating properties of a ferromagnetic carbon steel rod and a prototype Ti-coated needle using this carbon steel rod, were investigated in several high-frequency outputs at 300 kHz. In the former, the heating property was drastically different among the three inclination angles (θ = 0°, 45° and 90°) relative to the magnetic flux dir...

SnO2nanowire arrays were synthesized by fast heating a mixture of SnO2and the carbon nanotubes waste soot by high-frequency induction heating. The resultant SnO2nanowires possess diameters from 50 to 100 nm and lengths up to tens of mircrometers. The field-effect transistors based on single SnO2nanowire exhibit that as-synthesized nanowires have better transistor performance in terms of transco...

In this paper induction heating system is modeled and effective factors on induction heater system losses are represented. Respective to the intensive importance of capacitor losses and its potential ability of being harmful, furnace parameters must be designed in a way to minimize capacitor losses and maximize the transmitted power into the load. The effective parameters are the number of turn...

Energy-savings considerations in manufacturing processes have been drawing a great attention to the designers and manufactures because of the ecological issues, cost-saving pressure, and new environmental legislations. Manufacturing companies have been trying to “produce more with less”, so the improvement of machining and process efficiency for manufacturing is one of the promising solutions. ...

This paper presents a modified Current Source Parallel Resonant Push-pull Inverter (CSPRPI) for single phase induction heating applications. One of the most important problems associated with current source parallel resonant inverter is to achieve ZVS in transient intervals. This paper shows that the CSPRPI with integral cycle control method has dynamic ZVS. According to this method, it is the ...

Induction heating system has a number of inherent benefits compared to traditional heating systems due to a non-contact heating process. The main interesting area of the induction heating process is the efficiency of the usage of energy, choice of the plate material and different coil configurations based on application. Correctly designed, manufactured and maintained induction coils are critic...

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...
