INVESTIGATIONS ON THE ANOMALOUS OXIDATION BEHAVIOUR OF HIGH-CARBON GAS-BASED DIRECT REDUCED IRON (DRI)

摘要

Sponge iron or direct reduced iron (DRI) often shows a tendency to spontaneously combust in a moist oxygen-containing atmosphere. This tendency, however, is different for gas-based DRI compared with coal-based DRI. In this paper the unique oxidation behaviour of gas-based DRI is discussed and has been compared with the combustion behaviour of coal-based DRI. [References: 19]
