Study on the production of VAR electrodes from Zircaloy turning lathe chips

Abstract: ResumoCavacos de Zircaloy 4 são produzidos em larga escala durante a usinagem de tubos Zircaloy 4 para peças do elemento combustível de reatores PWR. Atualmente Zircaloy 4 é uma liga de zircônio importada para o Brasil e sua usinagem gera cavacos que são um desafio para a indústria da reciclagem. Esse trabalho apresenta o primeiro passo do processo de reciclagem e os resultados para a procura de uma maneira eficiente de limpeza, controle de qualidade e fabricação do eletrodo no VAR (Vacuum Arc Remelting). O pr… Show more
