The utility model relates to a smelting device, which is used in the present invention discloses a Holzer electrolytic cell by alumina electrolytic production of aluminum, the electrolytic cell having an anode, cathode, electrolyte and melting crucible, melting crucible for holding electrolyte, alumina and aluminum liquid layer, melting crucible has a bottom portion and a side portion and the aluminum layer in the melting crucible the bottom of the top with the specified height. The smelting apparatus comprises a wall, a wall disposed in the melting crucible, defining a sub region in the smelting crucible, and extending at least a portion of at least one of the length and width of the melting crucible. The wall separates the bottom of the crucible and prevents the movement of aluminum under the influence of the MHD force, thereby reducing the maximum crest height of the medium wave and reducing the ACD to reduce the resistance and power consumption. The wall can be equal to or exceed the height of the anode and can be used as a cathode when it is electrically conductive to attract horizontal current. The wall may be composed of alumina in the form of a block, which can be reduced by electrolysis and replaced periodically.
