Abstract

Perfeccionamientos en electrodos, refrigerados por líquido, para hornos de arco voltaico, con una camisa portadora de piezas metálicas refrigeradas, sujeta al brazo porta-electrodo, y con un núcleo desplazable axialmente dentro de la camisa, al cual es aplicable por medio de una toma de corriente la corriente para el electrodo, caracterizados en que la toma de corriente está dispuesta por encima de la camisa (3), en que la camisa está aislada eléctricamente respecto al núcleo (2, 31), en que el aislamiento comprende una capa aislante (19) entre la camisa y el núcleo y en que además se ha establecido en la parte inferior de la camisa un dispositivo (28) para la creación de un campo magnético.
