Title (EN) A DEVICE FOR MOVING SOLID MATERIAL FED ONTO THE SURFACE OF A MELT AND FOR BREAKING A SLAG CRUST FORMED ON THE SURFACE OF THE MELT OR INSIDE THE CHARGE
(FR) DISPOSITIF DE DEPLACEMENT D"UN MATERIAU SOLIDE AMENE SUR LA SURFACE D"UNE COULEE, ET DE RUPTURE D"UNE CROUTE DE LAITIER FORMEE A LA SURFACE DE LA COULEE OU A L"INTERIEUR DE LA CHARGE
Abstract: front page image
(EN)A device for poking a charge fed onto the surface of a melt in an electric arc furnace having a hood and an external cooled casing (2) articulated at one of its ends to the lower section (21) of a horizontal circumferential bend in the wall of the furnace (23) hood (24) which faces the melt, drive cylinders (5) for tilting the casing in different directions about its joint, a spindle (1) installed tightly in the cooled casing (2) and being axially reciprocating and rotatable, and drive cylinders (17) for making the spindle (1) to project from said one end of the casing (2) to poke the charge fed onto the melt surface and break any crust on the melt surface or inside the solid charge, when the cooled casing (2) and the spindle (1) inside it are tilted about the joint and rotated.
(FR)Dispositif de tisonnage d"une charge amenee a la surface d"une coulee dans un four a arc electrique ayant une hotte et un corps refroidi exterieurement (2) articule a l"une de ses extremites sur la section inferieure (21) d"une courbe circonferentielle horizontale dans la paroi de la hotte (24) du four (23) qui fait face a la coulee, des organes (5) de basculement du corps dans differentes directions autour de son articulation, un arbre (1) monte serre dans le corps refroidi (2) ayant un mouvement alternatif axial et rotatif, et des cylindres d"entrainement (17) pour projeter l"arbre (1) depuis cette extremite du corps (2) pour tisonner la charge amenee sur la surface de la coulee et casser les croutes eventuelles formees a la surface de la coulee ou a l"interieur de la charge solide, lorsque le corps refroidi (2) et l"arbre a l"interieur de celui-ci sont inclines autour de l"articulation et mis en rotation.
