Reduction processing apparatus for steel-making slag and reduction processing system for steel-making slag

A reduction processing apparatus for a steel-making slag that continuously performs reduction processing to a hot steel-making slag by using an electric furnace, the apparatus comprising:

• a slag-supplying container configured to charge the hot steel-making slag having fluidity into the electric furnace the hot-steel making slag having a rate of solid phase of not more than 30% if a temperature of the hot steel-making slag is 1400° C.;
• an electrode that is provided at the electric furnace and heats a molten slag layer on a molten iron produced by reducing the hot steel-making slag together with the molten iron;
• an auxiliary-raw-material supplying unit that supplies an auxiliary-raw-material including a reducing agent to the molten slag layer;
• and
• a tilting unit that tilts the slag-supplying container with a tilting axis being a center, and adjusts a charging amount of the hot steel-making slag to the electric furnace,
• wherein the electric furnace is a closed and fixed electric furnace.
