METHOD FOR UNDESTRUCTIVE STUDY OF REFRACTORY ELEMENT

摘要

The invention relates to a method for studying the internal structure of a refractory element, characterized in that it comprises the following steps: a) transmitting at least one electromagnetic wave, called a "pulse", to a refractory element to be studied by a transmitting antenna; b) receiving, by the receiving antenna, the specified pulse after it is reflected by the reflecting zone of the refractory element; c) analysis of the time shift between the two preceding stages to establish the position of the reflecting zone in the refractory element, with the specified pulse having a duration of less than or equal to 0.5 ns.
