Abstract

Dispositif d'amortissement des vibrations d'un système d'électrodes pour four à arc. Le dispositif est constitué par une masse pouvant coulisser dans un carter solidaire du porte-électrode. Le carter est rempli d'un liquide hydraulique de part et d'autre de la masse. Une conduite comportant un diaphragme réglable relie les deux côtés du carter. Application : aux électrodes de fours à arc.Device for damping the vibrations of an arc furnace electrode system. The device consists of a mass which can slide in a housing secured to the electrode holder. The crankcase is filled with hydraulic fluid on either side of the mass. A pipe with an adjustable diaphragm connects the two sides of the housing. Application: to arc furnace electrodes.
