Book Description
ONE OF A FOUR-BOOK COLLECTION SPOTLIGHTING CLASSIC ARTICLES Landmark research findings and reviews in aluminum reduction technology Highlighting some of the most important findings and insights reported over the past five decades, this volume features many of the best original research papers and reviews on aluminum reduction technology published from 1963 to 2011. Papers have been organized into seven themes: 1. Fundamentals 2. Modeling 3. Design 4. Operations 5. Control 6. Environmental 7. Alternative processes The first six themes deal with conventional Hall-Héroult electrolytic reduction technology, whereas the last theme features papers dedicated to nonconventional processes. Each section begins with a brief introduction and ends with a list of recommended articles for further reading, enabling researchers to explore each subject in greater depth. The papers for this volume were selected from among some 1,500 Light Metals articles. Selection was based on a rigorous review process. Among the papers, readers will find breakthroughs in science as well as papers that have had a major impact on technology. In addition, there are expert reviews summarizing our understanding of key topics at the time of publication. From basic research to advanced applications, the articles published in this volume collectively represent a complete overview of aluminum reduction technology. It will enable students, scientists, and engineers to trace the history of aluminum reduction technology and bring themselves up to date with the current state of the technology.

Book Description
Inhaltsangabe:Introduction: The process of aluminium production is, even nearly 150 years after its discovery, not totally understood. Such a large quantity of factors influences the production process that no standard can be applied on it. In an aluminium reduction plant there are no two identical electrolysis cells. Differences in the start-up and operational disturbances alter the thermal and electrical behaviour of each cell individually. So every cell has to be monitored individually through the continuous changing bath composition and temperature variation. Every cell needs an individual dynamic optimisation of the chemical and thermal input, e.g. the AlF3- and CaF2-addition and the regulation of the anode-cathode distance. Self-regulating mechanism are the melting and freezing of the sidewall ledge, external mechanisms the lifting and lowering of the anodes. In this work a cell control system at Alumar (Brazil) was analysed and improved. The focus laid on controlling the cell temperature through a variation of the anode-cathode distance. The main objective was to analyse the effect and influence of a so-called temperature resistance modifier on hot pots (electrolysis cells). When the temperature of an electrolysis cell exceeds a certain limit, the pot operates outside its optimal working conditions, thus it has to be cooled down. This can happen by reducing the anode-cathode distance and therefore the resistance of the pot. The reduction is controlled by the so-called temperature resistance modifier. The concept of the temperature modifier was introduced less than one year ago at Alumar and is also within the Alcoa group a quite unexplored field. This work is structured in two parts, first an introduction to theory, then the practical part. Chapter 2 gives some general information, from the history of aluminium to a brief overview over the entire production process. Chapter 3 focuses on the general functioning of the aluminium electrolysis. Chapter 4 details the properties of the cryolite bath in the reduction cell and their impacts on the pot operating characteristics. Chapter 5 contains the experimental part of the work. In a first time the quality of the measurement system was tested. Then the relations between temperature resistance modifier and time as well as two bath parameters, the temperature and the ratio were inquired. Thereafter substantial modifications on the program that calculates the temperature modifier were analysed [...]
