The present paper develops a one-dimensional model of a novel coal based iron ore direct reduction process. In this process, a mixture of iron ore, coal fines and small amount of binder is made into pellets and these are placed in a bed. Air is force

The reduction of hematite iron ore fines by different carbonaceous materials in composite pellets in a one-layer bed under nonisothermal asymmetric heating from above is studied. Temperature measurements at various points in the bed show that there a

A mathematical model of the coal-based direct reduction process of iron ore in a pellet composed of coal and iron ore mixture is investigated using a finite-control volume method. Heat transfer by conduction in the solid, convection by gaseous media

The published approaches to the mathematical modeling of rates of reduction, of coal gasification, and of devolatilization of coal in iron/ore coal composites are reviewed and critically analyzed. The effect of different parameters on the overall pro

This paper gives an overview of the theoretical and practical issues involved in nitrogen control in steelmaking. A series of bench-scale experiments have been carried out to assess the ability of low-grade iron carbide to enhance nitrogen desorption

This paper describes a study of the optimisation of the modelling of the direct reduction process in swelling coal char-hematite composite pellets. Approximations of important physical parameters such as heats of reaction, specific heat and thermal c
