PROPORTIONING GATE OF BLAST-FURNACE CHARGING DEVICE

摘要

FIELD: metallurgy, particular, gates of blast-furnace charging device. SUBSTANCE: the offered proportioning gate has airtight body accommodating branch pipe with two turning jaws located under discharge opening of branch pipe. Cross-section of branch pipe discharge opening is polygonal in shape. Polygon is formed by two plow-shaped inserts located in branch pipe. Tops of plow-shaped inserts are directed to each other in vertical plane running over branch pipe axis. EFFECT: provision of optimal passage of charge in any intermediate position of jaws resulting in improved conditions of material supply. 3 dwg,
