AI Technical Summary

Technical Problem

The existing direct reduction processes for producing direct reduced iron (DRI) face challenges with high greenhouse gas emissions, particulate matter generation, and inefficient carbon addition during steelmaking, leading to non-uniform carbon distribution and loss in the molten bath.

Method used

A production plant and method that integrates a briquette forming machine, carbon metering device, and recovery system to compress and heat carbon with DRI, forming briquettes with sufficient carbon content, while recovering volatile substances to prevent flammability and ensure uniform carbon distribution.

Benefits of technology

The solution enables the production of high-temperature briquettes with appropriate carbon content for electric steelmaking, reducing emissions and ensuring efficient carbon addition without the need for additional carbon injection, thus optimizing the steelmaking process.

Abstract

A direct reduced iron (DRI) briquette production plant comprising a direct reduced iron (DRI) supply line and at least one briquette forming machine (4, 4') located downstream of the supply line (1) for compressing the direct reduced iron (DRI) into briquettes, a carbon quantitative supply device (5, 13) for adding carbon to the direct reduced iron (DRI) located upstream of the at least one briquette forming machine (4, 4') so that the carbon is compressed together with the direct reduced iron (DRI) in the at least one briquette forming machine (4, 4'), at least one heating device located upstream of the at least one briquette forming machine (4, 4') for heating the carbon, and at least one recovery system (19) located upstream of the at least one briquette forming machine (4, 4') for recovering volatile substances that may be released from the carbon during heating by the at least one heating device.
