Abstract:
The present invention relates generally to a method and system for the supply of a continuous stream of hot direct reduced iron (HDRI) from a direct reduction (DR) shaft furnace or direct reduced iron (DRI) reheating furnace to a point outside of the DR shaft furnace or DRI reheating furnace where the HDRI stream is split into at least two HDRI streams. The first HDRI stream is sent continuously to a hot briquetting plant by gravity in a closed duct system. The second HDRI stream is sent continuously to an adjacent melting furnace also by gravity in a closed duct system, with a surge bin and feeders, or by a combination of gravity in a closed duct system, also with a surge bin and feeders, and a generally horizontal charge conveyor. Optionally, a third HDRI stream is employed to continuously feed multiple hot transport vessels.
