CBI (Sponge Iron)

Introduction

CBI is produced from the different residual products manufactured during the production of combined ferrous products and semi-refined raw material containing sponge iron (DRI fines and also other residuals). Some producers use cold briquette in their pellet DRI so that they can feed it into their particular furnace. CBI is produced at a temperature below 650° C, and a binder is generally needed.

Shipping and Logistic

Since the briquetting process has proceeded at a temperature lower than that used for HBI, some of the key specifications of DRI, like porosity, almost large surface space, and a reactive surface, last in the CBI to some degree, so, basically, CBI can have very similar or the same specifications to pellet DRI and shall be handled in exactly the same way, as the tendency to overheating and generating hydrogen gas, if it gets wet, still remains. It is definitely of significance to know the original source of material used to produce CBI. If this cannot be verified, then the CBI shall be handled and shipped in the same manner to DRI.
