METHOD AND SYSTEM FOR THE SUPPLY OF HOT DIRECT REDUCED IRON FOR MULTIPLE USES

摘要

The present invention relates generally to a method and system for the su pply 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 th e 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 feeder s, 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 ve ssels.
