Patent Abstract

The method involves accelerating a radiating agent (110) directly by a spinner or indirectly by pressurized air (104). The radiating agent is impinged on a surface to be treated of a casting workpiece (102). The radiating agent is directly heated by the pressurized air as desired before impinging on the surface for causing heat treatment and/or thermal cleaning of the workpiece during impinging on the surface. The radiating agent and/or the carrier material is provided with a material i.e. silicon carbide, including a high suitability for dielectric heating. An independent claim is also included for a device for performing a method for treating a casting workpiece.
