摘要： A process for continuous production of a large sized zinc-base alloy ingot which comprises: EMPLOYING AN ALLOYING FURNACE COMPRISING (I) A MIXING FURNACE HAVING AT LEAST ONE CHARGING WELL PROVIDED WITH A SIDE WALL OF SAID MIXING FURNACE AND AT LEAST ONE AGITATING MEANS EQUIPPED WITH A COVER WALL OF SAID MIXING FURNACE, (II) A MUFFLE FURNACE CONNECTED WITH SAID MIXING FURNACE AND HAVING AT LEAST ONE DISCHARGING WELL PROVIDED WITH A SIDE WALL OF SAID MUFFLE FURNACE AND (III) A PARTITION WALL HAVING AN OVERFLOWING CHANNEL AND INTERPOSED AT A BOTTOM OF A CONNECTED PORTION BETWEEN SAID BOTH FURNACES; INTRODUCING A CERTAIN AMOUNT OF A MOLTEN ZINC AND AT LEAST ONE ALLOYING METAL INGOT INTO SAID CHARGING WELL WHILE AGITATING SAID MOLTEN ZINC INTRODUCED; REPEATING THE INTRODUCTION OF SAID MOLTEN ZINC AND SAID ALLOYING METAL INGOT AT INTERVALS OF A FIXED TIME, THEREBY A MOLTEN ZINC-BASE ALLOY BEING CONTINUOUSLY FORMED AND INTERMITTENTLY OVERFLOWED BEYOND SAID PARTITION WALL FROM SAID MIXING FURNACE INTO SAID MUFFLE FURNACE; SUCCESSIVELY CASTING A CERTAIN AMOUNT OF THE RESULTING ALLOY INTO A LARGE-SIZED INGOT BY DIPPING UP SAID MOLTEN ALLOY FROM SAID DISCHARGING WELL AND INTRODUCING SAID MOLTEN ALLOY INTO A MOLD; AND REGULATING AN AMOUNT OF INTRODUCTION OF MOLTEN ZINC AND ALLOYING METAL INGOT PER UNIT TIME SO THAT THE INTRODUCING AMOUNT OF THE RAW MATERIAL INTO SAID MIXING FURNACE AND THE DISCHARGING AMOUNT OF THE MOLTEN ALLOY FROM SAID MUFFLE FURNACE MAY BE MAINTAINED IN A STATE OF APPROXIMATELY EQUILIBRIUM.
