Method of making aluminum alloys

Claim 1

A METHOD OF MAKING VANADIUM-ALUMINUM ALLOYS CONTAINING FROM 45% TO 90% OF ALUMINUM AND FROM 10% TO 55% OF VANADIUM, WHICH COMPRISES PROVIDING IN A REACTION VESSEL, A POOL OF ALUMINUM, ESTABLISHING, DURING A START-UP PERIOD, A SLAG COVER ON THE POOL OF ALUMINUM BY CHARGING ONTO THE POOL OF ALUMINUM A START-UP CHARGING MIXTURE CONSISTING ESSENTIALLY OF AN EXOTHERMIC REACTION MIX AND FLUX, THE EXOTHERMIC REACTION MIX CONSISTING ESSENTIALLY OF V2O5 AND AL, THE FLUX CONSISTING ESSENTIALLY OF LIME AND FLUORSPAR, THE WEIGHT RATIO OF SAID FLUX TO SAID EXOTHERMIC REACTION MIX IN SAID CHARGING MIXTURE BEING BETWEEN 0.17:1 AND 0.40:1, AND THE WEIGHT RATIO OF LIME OF FLUORSPAR IN SAID FLUX BEING BETWEEN 1.4:1 AND 2.8:1, AND AFTER A SLAG COVER HAS BEEN ESTABLISHED, CHARGING ONTO THE SLAG, DURING A RUNNING PERIOD, A CHARGING MIXTURE CONSISTING ESSENTIALLY OF AN EXOTHERMIC REACTION MIX AND FLUX, THE EXOTHERMIC REACTION MIX CONSISTING ESSENTIALLY OF V2O5 AND AL, THE FLUX CONSISTING ESSENTIALLY OF LIME AND FLUORSPAR, THE WEIGHT RATIO OF SAID FLUX TO SAID EXOTHERMIC REACTION MIX IN SAID CHARGING MIXTURE BEING BETWEEN 0.05:1 AND 0.15:1, AND THE WEIGHT RATIO OF LIME TO FLUORSPAR IN SAID FLUX BEING BETWEEN 0.20:1 AND 1.0:1, WHEREBY THE V2O5 AND AL REACT TO FORM ALUMINA WHICH IS ABSORBED BY THE SLAG AND VANADIUM METAL WHICH ALLOYS WITH THE ALUMINUM IN THE POOL.

Claim 2

A METHOD OF MAKING VANADIUM-ALUMINUM ALLOYS CONTAINING FROM 45% TO 90% OF ALUMINUM AND FROM 10% TO 55% OF VANADIUM, WHICH COMPRISES PROVIDING IN A REACTION VESSEL, A POOL OF ALUMINUM, ESTABLISHING, DURING A START-UP PERIOD, A SLAG COVER ON THE POOL OF ALUMINUM BY CHARGING ONTO THE POOL OF ALUMINUM A START-UP CHARGING MIXTURE CONSISTING ESSENTIALLY OF AN EXOTHERMIC REACTION MIX AND FLUX, THE EXOTHERMIC REACTION MIX CONSISTING ESSENTIALLY OF V2O5 AND AL, THE FLUX CONSISTING ESSENTIALLY OF LIME AND FLUORSPAR, THE WEIGHT RATIO OF SAID FLUX TO SAID EXOTHERMIC REACTION MIX IN SAID CHARGING MIXTURE BEING BETWEEN 0.17:1 AND 0.40:1, AND THE WEIGHT RATIO OF LIME OF FLUORSPAR IN SAID FLUX BEING BETWEEN 1.4:1 AND 2.8:1, AND AFTER A SLAG COVER HAS BEEN ESTABLISHED, CHARGING ONTO THE SLAG, DURING A RUNNING PERIOD, A CHARGING MIXTURE CONSISTING ESSENTIALLY OF AN EXOTHERMIC REACTION MIX AND FLUX, THE EXOTHERMIC REACTION MIX CONSISTING ESSENTIALLY OF V2O5 AND AL, THE FLUX CONSISTING ESSENTIALLY OF LIME AND FLUORSPAR, THE WEIGHT RATIO OF SAID FLUX TO SAID EXOTHERMIC REACTION MIX IN SAID CHARGING MIXTURE BEING BETWEEN 0.05:1 AND 0.15:1, AND THE WEIGHT RATIO OF LIME TO FLUORSPAR IN SAID FLUX BEING BETWEEN 0.20:1 AND 1.0:1, WHEREBY THE V2O5 AND AL REACT TO FORM ALUMINA WHICH IS ABSORBED BY THE SLAG AND VANADIUM METAL WHICH ALLOYS WITH THE ALUMINUM IN THE POOL.
