Abstract

La sonde comprend une structure portante 1 en métal, une chambre tubulaire 2 en réfractaire, un tube axial 3 en acier inox pour le passage d'un fluide réfrigérant et de fils de connexion, une enveloppe protectrice 4 et 5 interne qui contient le détecteur 7 et 8 où circule le fluide réfrigérant et dont la face 11 dirigée vers la pièce à examiner et laissant passer le flux magnétique est constituée par au moins une lamelle en un matériau diélectrique résistant à la chaleur. Application à l'examen direct des produits coulés en continu.The probe comprises a supporting structure 1 made of metal, a tubular chamber 2 made of refractory, an axial tube 3 made of stainless steel for the passage of a coolant and connection wires, an internal protective casing 4 and 5 which contains the detector 7 and 8 in which the refrigerant circulates and the face 11 of which faces the part to be examined and which allows the magnetic flux to pass is constituted by at least one strip of a dielectric material resistant to heat. Application to the direct examination of continuously cast products.
