Method and device for fixing a consumable electrode in an arc melting furnace under vacuum.

摘要

METHOD AND ELECTRODE ASSEMBLY FOR USE IN THE FOUNDRY, CONSUMABLE ELECTRODE ARC OF METALS AND ALLOYS, PARTICULARLY TITANIUM AND TITANIUM ALLOYS BASE. The method includes forming an ASSEMBLY consisting of a metal electrode or alloy to be melted. An elongated ring, which is built of metal or alloy, has its one end connected to one end of the electrode and the other end connected to an electrode holder, which, CONNECTED TO THE BEGINNING OF ELECTRIC POTENTIAL. The ring has an outer diameter smaller than the outer diameter of the electrode to form an annular border area on the end of the electrode surface. MARGINAL VOID THIS AREA IS DEFINED THROUGH THE RING AND THE PERIPHERY the end of the electrode surface. ASSEMBLY THIS POINT IS LOCATED WITHIN A MOLDING REFRIGERADA of conductive material, said coving is also connected to a principle of POTENCIALELECTRICO. SE produces an electric current between the electrode and TRIM TO PRODUCE an arc from the electrode tip and welding CONTINUOUSLY the electrode to form a stick. CONTINUOUS CASTING MARGINAL AREA UNTIL THE VOID BEGINS AT LEAST A MELT AND FOUNDRY IS BROKEN BEFORE THE MARGINAL AREA HAS BEEN COMPLETELY BLOWN. FROM HERE FADE OPERATION CAN BE LOCKED BEFORE THE COMPLETELY CONSUMED ELECTRODE HAS TO PREVENT POLLUTION BY BAR CASTING MATERIAL FROM RING OR SUJETAELECTRODOS.
