Review of the High-Temperature Oxidation of Iron and

This paper reviews previous studies on iron and steel oxidation in oxygen or air at high temperatures. Oxidation of iron at temperatures above 700°C follows the parabolic law with the development of a three-layered hematite/magnetite/wüstite scale structure. However, at temperatures below 700°C, inconsistent results have been reported, and the scale structures are less regular

Minerals Free Full-Text Experiences of Bio-Coal

Metal production, and especially iron ore-based steel production, is characterized by high fossil CO2 emissions due of the use of coal and coke in the blast furnace. Steel companies around the world are striving to reduce the CO2 emissions in different ways, e.g., by use of hydrogen in the blast furnace or by production of iron via direct reduction.
