摘要

"The process to improve the yield and quality of casting of metals and alloys raw fusion, apparatus for applying a mobile electric arc on metals and alloys in fusion, and the electrode.An apparatus (10) and a process to reduce inclusions, cavities product of contraction, porosity and segregation in metal products casting during the casting process.And to improve the granular structure, mechanical properties and yield of casting ingots and other products.The apparatus (10) comprises: at least one electrode (14) to form an electric arc mobile (16) on the upper surface (18) of a metallic product casting (12) being cast and a bracket (20).For suspending the electrode electric arc (14) on the upper surface (18) of the product metal casting (12) during or after the leak, and a second electrode (24) afixu00e1vel an areaMetal (26) in the mold (28) being used for the casting.To complete an electrical circuit (30) including the electric arc (16) and electronic controls (32) connected between the device (10) and a power source.
