Abstract
A method for testing the internal structure of a refractory part, has the following steps: a) by a transmission antenna, sending at least one electromagnetic wave, termed a “pulse”, into the refractory part to be tested; b) by a reception antenna, receiving the pulse after reflection thereof by a reflecting zone of the refractory part; c) analyzing the time offset between the two preceding steps in order to deduce the position, in the refractory part, of the reflecting zone, the pulse having a duration less than or equal to 0.5 nanoseconds.
Claims10
A method for inspecting the internal structure of a refractory part, said method including the following steps:
- a) transmitting, by means of an emitting antenna, at least one electromagnetic wave, called the “pulse”, into the refractory part to be inspected;
- b) receiving, by means of a receiving antenna, said pulse after it has been reflected by a reflecting zone of the refractory part;
- and
- c) analyzing the time shift between the two preceding steps in order to deduce therefrom the position, in the refractory part, of the reflecting zone, said pulse having a duration shorter than or equal to 0.5 nanoseconds.
