Abstract: A production apparatus and method for electric arc furnace steelmaking with a fully continuous ultra-short process are provided. A continuous adding, melting, smelting and continuous casting of a metal material are integrated, and a metallurgy process is completed in a flowing of a molten steel, to realize a continuous production of ingot blanks. The production apparatus includes four operation sites of an electric arc furnace for melting and primary refining, a sealed tapping chute for molten steel flowing, a refinement storage bed for molten-steel desulfurization and alloying and a conticaster for continuous casting A material flow, an energy flow and a time stream in the four operation sites are in a dynamic equilibrium. The production apparatus and method realize a molten-steel casting is started within 120 minutes after the metal material is started to be continuously added, and an uninterrupted continuous production is maintained for above 80 hours.
