Electric arc furnace and the process of preparing castings

Claim 1

THE METHOD OF SIMULTANEOUSLY PREPARING A TITANIUM BASE ALLOY AND CASTING IT INTO THE FORM OF AN ANGULARLY-SHAPED FLAT CASTING WHICH COMPRISES INSERTING WITHIN AND IN SPACED RELATION TO THE WALLS OF A SUBSTANTIALLY CLOSED FURNACE, A MOLD HAVING A FLAT BOTTOM WALL AND AN ANGULARLY-SHAPED CASTING CAVITY, FEEDING INTO A PORTION OF THE CAVITY OF THE MOLD A MIXTURE COMPRISING A PREDOMINANT AMOUNT OF TITANIUM IN THE FORM OF SMALL PARTICLES AND A MINOR AMOUNT OF AT LEAST ANOTHER METAL IN THE FORM OF SMALL PARTICLES IN SUCH RELATIVE PROPORTION TO THE TITANIUM PARTICLES THAT IT WILL FORM AN ALLOY WITH THE TITANIUM WHEN THE METALS ARE MIXED TOGETHER THE MOLTEN STATE, APPLYING SUFFICIENT ELECTRICAL ENERGY TO AN ELECTRODE HAVING A FREE END PORTION ARRANGED IN THE CAVITY OF THE MOLD IN PROXIMITY TO THE MIXTURE OF METAL PARTICLES BEING FED INTO THE CAVITY OF THE MOLD TO MELT THE METAL PARTICLES, ALTERNATELY MOVING SAID MOLD IN OPPOSITE DIRECTIONS IN A HORIZONTAL PATH RELATIVE TO SAID ELECTRODE AND THE MIXTURE OF METAL PARTICLES BEING FED INTO THE CAVITY OF THE MOLD TO PROVIDE A UNIFORM DEPOSIT OF THE MOLTEN METAL WITHIN THE ANGULARLY-SHAPED CAVITY OF THE MOLD, PASSING THROUGH THE FURNACE DURING THE MELTING OPERATION A GAS WHICH IS INERT TO THE METAL PARTICLES BEING MELTED TO COOL THE FURNACE AND TO REMOVE FROM THE FURNACE VOLATILE IMPURITIES FROM THE MIXTURE OF METAL PARTICLES WHILE THEY ARE BEING MELTED WITHIN THE CAVITY OF THE MOLD, AND COOLING THE MOLD TO SOLIDIFY THE METAL DEPOSITED THEREIN INTO AN ANGULARLY-SHAPED FLAT CASTING.

Claim 2

THE METHOD OF SIMULTANEOUSLY PREPARING A TITANIUM BASE ALLOY AND CASTING IT INTO THE FORM OF AN ANGULARLY-SHAPED FLAT CASTING WHICH COMPRISES INSERTING WITHIN AND IN SPACED RELATION TO THE WALLS OF A SUBSTANTIALLY CLOSED FURNACE, A MOLD HAVING A FLAT BOTTOM WALL AND AN ANGULARLY-SHAPED CASTING CAVITY, FEEDING INTO A PORTION OF THE CAVITY OF THE MOLD A MIXTURE COMPRISING A PREDOMINANT AMOUNT OF TITANIUM IN THE FORM OF SMALL PARTICLES AND A MINOR AMOUNT OF AT LEAST ANOTHER METAL IN THE FORM OF SMALL PARTICLES IN SUCH RELATIVE PROPORTION TO THE TITANIUM PARTICLES THAT IT WILL FORM AN ALLOY WITH THE TITANIUM WHEN THE METALS ARE MIXED TOGETHER THE MOLTEN STATE, APPLYING SUFFICIENT ELECTRICAL ENERGY TO AN ELECTRODE HAVING A FREE END PORTION ARRANGED IN THE CAVITY OF THE MOLD IN PROXIMITY TO THE MIXTURE OF METAL PARTICLES BEING FED INTO THE CAVITY OF THE MOLD TO MELT THE METAL PARTICLES, ALTERNATELY MOVING SAID MOLD IN OPPOSITE DIRECTIONS IN A HORIZONTAL PATH RELATIVE TO SAID ELECTRODE AND THE MIXTURE OF METAL PARTICLES BEING FED INTO THE CAVITY OF THE MOLD TO PROVIDE A UNIFORM DEPOSIT OF THE MOLTEN METAL WITHIN THE ANGULARLY-SHAPED CAVITY OF THE MOLD, PASSING THROUGH THE FURNACE DURING THE MELTING OPERATION A GAS WHICH IS INERT TO THE METAL PARTICLES BEING MELTED TO COOL THE FURNACE AND TO REMOVE FROM THE FURNACE VOLATILE IMPURITIES FROM THE MIXTURE OF METAL PARTICLES WHILE THEY ARE BEING MELTED WITHIN THE CAVITY OF THE MOLD, AND COOLING THE MOLD TO SOLIDIFY THE METAL DEPOSITED THEREIN INTO AN ANGULARLY-SHAPED FLAT CASTING.
