This work addresses the critical challenge of accurately determining the inner states of three-phase electric smelting furnaces, commonly used in ferro-alloy and silicon production. Gaining insights into these internal states is crucial for optimizing furnace performance, energy ... Per saperne di più
Plasma torches are essential components in high-temperature applications such as plasma gasification, where stable and focused energy delivery is critical for the efficient conversion of waste into syngas. A key challenge in these systems lies in understanding and optimizing the gas ... Per saperne di più
The current and energy transfer to cathodes of vacuum arcs usually occurs in bright, narrow regions, known as cathode spots. Owing to extreme conditions in these spots, the cathode surface is eroded: electrode material is vaporized, and craters and molten metal jets are formed. The study ... Per saperne di più
This work, which is done in the framework of the SisAl Pilot EU project, presents the use of the COMSOL Multiphysics® software for simulating an ensemble averaged electric arc in a laboratory-scale electric arc furnace. The SisAl Pilot project aims at optimising the silicon production in ... Per saperne di più
In the nuclear industry, and particularly at Framatome, mastery of welding processes is essential. Framatome is one of the world leaders in this field and wants to improve even more. The work presented focuses on improving the TIG (Tungsten Inert Gas) welding process, and more ... Per saperne di più
Nowadays, surge protection devices are widely used in electrical grids to suppress over voltages during transient conditions caused by voltage surges and to prevent damages of industrial or household devices. The working principle is based on the initiation of an arc with a burning ... Per saperne di più
Manufacturing of metal component in industry involves many kind of processes where materials experience high temperature and changes of state.
