Document Type and Number:
WIPO Patent Application WO/2017/206595
Kind Code:
A1
Abstract:
A feeder device utilized in an electric arc furnace (1), and a flue gas and temperature control method. The feeder device comprises a sealed feeding chute (5) having an outlet sealedly communicating with a side wall of the electric arc furnace (1), and a material blocking sealed arc-shaped door (3) disposed in the sealed feeding chute (5). The material blocking sealed arc-shaped door (3) separates the sealed feeding chute (5) into a cold steel scrap storage chamber (18) and a material feeding and dust removal chamber (2), and is operated by a driving mechanism (34) to separate or communicate the cold steel scrap storage chamber (18) and the material feeding and dust removal chamber (2). The method comprises: adopting the electric arc furnace (1) to divide flue gas into two paths, and controlling, by a flue gas adjustment device (16), a ratio of a flue gas flow from a flow-splitting dust removal pipe (11) to that from a dust removal pipe (4) to obtain a required flue gas mixture temperature.
