TL;DR: In this article, a mathematical model that simulates the electroslag remelting (ESR) operation was developed and used to evaluate the influence of operating variables, such as the fill ratio, and the thermophysical properties of the slag.

TL;DR: In this paper, a numerical model is presented, designed to simulate the kinetic and thermal behavior of a porous pellet in which any gas-solid reaction is taking place, which can deal with reactions whether they are exothermic or endothermic, whether they were equimolar or not, whether their reversible or irreversible, and further reactions in the transient regime and even the possible presence of inert gases and solids.

TL;DR: In this article, the reduction of pure hematite by hydrogen was studied at the laboratory scale, varying the experimental conditions and observing the rate and the course of the reaction, all the reduction experiments were performed in a thermobalance and supplementary characterization methods were used like scanning and transmission electron microscopy, X-ray diffraction and Mossbauer spectrometry.
