The use of radioactive sources for the study of wear in refractory linings; L'emploi de sources radioactives pour l'etude de l'usure des revetements refractaires

Abstract

Following a discussion on the radioactive method for studying wear in refractory linings (description of the method, advantages and disadvantages, choice of radioactive indicator and detection), the article deals in some detail with the problems of safety involved in this technique. The two most important points discussed are: 1- the need to fix an upper limit of activity in the cast iron: the authors propose a figure of 1 mc of cobalt 60 in 500 tons; 2- the precautions necessary to remedy the diffusion of cobalt 60 in the brickwork (development of special pyro-ceramic sources). After a discussion on the international view point regarding the use of the method, a brief outline of some French projects is given, with particular reference to the case of a blast furnace. A note from the Commission interministerielle des Radioelements is given as an appendix; this deals with special conditions laid down for the use of radioelements in the determination of wear in refractory walls.

Les deux points les plus importants discutes dans ce rapport sont: 1- la necessite de fixer l'activite limite de la fonte et les auteurs proposent ici le chiffre de 1 mc de cobalt 60 dans 500 tonnes de fonte; 2- les remedes a apporter a la diffusion du cobalt 60 dans la maconnerie (realisation de sources speciales en pyrocerame). Apres avoir examine le point de vue international sur l'utilisation de la methode, l'article decrit brievement quelques realisations francaises en etudiant plus particulierement le cas d'un haut-fourneau. En annexe, se trouve une note de la Commission interministerielle des Radio-elements traitant des conditions particulieres d'emploi des radio-elements destines a la determination de l'usure des parois refractaires.
