No. 11.7 HBI – Hot Briquetting of Direct Reduced Iron ...
Hot briquetting is a reliable, fully developed industrial concept for the passivation of direct reduced iron produced with the various processes of direct reduction. Because, during hot briquetting, the large specific surface area of direct reduced iron is drastically reduced, the well known problems caused by reoxidation, overheating are avoided.
