Document Type and Number:
WIPO Patent Application WO/2014/003127
Kind Code:
A1
Abstract:
This steel slag reduction equipment continuously reduces hot steel slag using an electric furnace, and is provided with: a slag supply container inside the electric furnace into which hot steel slag flows; an electrode that is provided to the electric furnace, and heats a molten slag layer on molten iron generated by reducing the hot steel slag; an auxiliary material supply part that supplies auxiliary material containing a reducing material to the molten slag layer; and a tilting device that tilts the slag supply container so as to adjust the amount of hot steel slag that flows into the electric furnace.
