RF industrial heating

Induction heating: precision plus reproducibility Thales has developed a new technology for these tubes, namely the pyrolytic grid. Based on the crystallization of pyrolytic graphite, it produces a single-piece part, without any welds. This structure, coupled with

Automated outgassing facility with inductive heating:

Induction heating is used to heat the sample to 2000 C. This heating technique was chosen to avoid heating other components in the vacuum chamber. Since the walls are heated by radiation from the sample at the higher temperatures, they are kept at a constant elevated temperature of 100 C by thermostatically controlled heaters throughout the experiment.

Carbonization, graphitization, and machining of

Carbonization of molded graphite: carbonizing (also known as baking) the green shape is the next step. Carbonization takes place in a furnace in an inert or reducing atmosphere. The process may last from a few days to several weeks depending on the constituents, and the size and geometry of the part. The temperature is raised slowly to 600C, at which stage the binder softens, volatiles are

Inductive Heating

Jacek P. Dworzanski, Henk L.C. Meuzelaar, in Encyclopedia of Spectroscopy and Spectrometry, 1999Curie-point pyrolysers Curie-point pyrolysis takes advantage of fast inductive heating of ferromagnetic materials placed in the high frequency (0.5–1.0 MHz) electromagnetic field generated inside the inductive coil surrounding the pyrolytic reaction tube.

What is Induction Heating and How do Induction Coils

Induction heating is an accurate, fast, repeatable, efficient, non-contact technique for heating metals or any other electrically-conductive materials. An induction heating system consists of an induction power supply for converting line power to an alternating current and delivering it to a workhead, and a work coil for generating an electromagnetic field within the coil.

Pyrolytic carbon and pyrolytic graphite

Pyrolytic graphite can be prepared through a CVD process by thermally decomposing a hydrocarbon gas such as methane, ethylene or acetylene at about 1100C by the induction heating of a substrate under taken at either a low pressure, when the product tends to be isotropic or, at pressures upto 1 atm (101kPa), when it is necessary to dilute with a non-reactive gas such as argon or hydrogen to

Effect of Nanobubbles on the Flotation Performance of

The highly oriented pyrolytic graphite (HOPG) was used as substrate to simulate the coal surface. The nanobubbles were generated by the temperature difference method, that is, two pipes were connected to the cell for fluid replacement with 20 C water instead of 7 C cold water on the surface of HOPG.

According to the invention, the process consists of immersing a porous structure made e.g. from carbon or graphite in a liquid hydrocarbon, such as for example cyclohexane, and heating it by induction and preferably to a temperature between 1000 and 1300

The induction heating of pyrolytic graphite

Using a pyrolytic graphite susceptor in this way, sizable systems can be heated to high temperatures without any additional thermal insulation. The larger the diameter of the susceptor, the lower the frequency which can be used for efficient coupling, and thus the larger the temperature difference which can be established across the susceptor wall.
