Abstract: Currently metallurgical and machine-building industries for nonferrous metal workpieces heating use induction installations of longitudinal magnetic field with electrical efficiency less than 0.5. The reported induction heating installations with rotated permanent magnets give the electrical efficiency up to 0.75-0.85 in heating of ...

2023年3月1日 · Magnetic induction heating revealed heating capabilities near to 46 ℃ for approximately 35 min at concentration 15 mg/mL. For NPs concentrations of 15 mg/mL, a SAR of 83.3 W/g was found. The communication describes prospects of ferrite with composition Co 0.88 Cu 0.12 Fe 2 O 4 suitable for magnetic hyperthermia.

MAGNHEAT is a LIFE project proposed to demonstrate the possibility of industrial application of a new technology for the induction heating of aluminum billets before extrusion. This technology uses Permanent Magnet Heaters (PMH), which constitute a high efficiency solution for the heating of high conductive metals.

2017年7月1日 · To study the effect of various types of magnetic field concentrators on the energy and thermal characteristics of the induction heating system of noncylindrical billets in the magnetic field of rotating permanent magnets, a numerical model was developed. The model allows solving the conjugate electromagnetic and thermal problem.

Abstract—We present simulations and demonstrate experimentally a new concept in winding a planar induction heater. The winding results in minimal ac magnetic field below the plane of the heater, while concentrating the flux above. Ferrites and other types of magnetic shielding are typically not required.

2024年1月10日 · In this paper, we propose a new design specification for a cylindrical dipole-type DC induction heating HTS magnet and analyze the operational characteristics of the prototype. The HTS magnets include a HTS coil excitation system, a dipole-type core permeability system, and a liquid nitrogen temperature zone system.

This is actually the role of magnetic field concentrator using in inductive heating processes. To achieve these magnetic concentrators in practice it is using a variety of materials and could therefore be useful brief review of their focusing on magnetodielectric materials made and used in the study approached the work.

2005年5月16日 · This paper presents results obtained in the designing of a heating device, which utilized eddy current induced by rotating permanent magnets. The finite-element method, by using overlap grid coordinate system, is used for the eddy-current analyses.

2015年1月1日 · Aluminum billets are heated at a prescribed temperature before hot working in gas or induction or resistance furnaces. Temperature distribution variable along the billet axis, or ‘taper profile’ with the initial section hotter than the final part of the billet, improves the extrusion process (isothermal extrusion).

2024年10月21日 · We demonstrate magnetic induction heating (MIH) with superparamagnetic iron oxide nanoparticles (IONPs) as a new rapid and energy-efficient methodology for synthesizing metal–organic frameworks (MOFs). Acting as localized heat sources, these IONPs overcome the energy losses associated with traditional solvot …
