Book Description
Excerpt from The Electric Furnace The very high range of temperatures attainable in electric furnaces has opened up a large field of chemistry which was not previously accessible. In the case of processes in which the electric current merely acts as a heating agent and is dissociated from any electrolytic action, products such as artificial graphite, the highly refractory metals in a compact form, and a large series of compounds of carbon with metals, have been isolated for the first time. In many cases these products have received an industrial application which has already ranged them in the forefront of the world's manufacturing processes. With other substances, notably certain classes of steel and iron and ferro-alloys, aluminium and sodium, the agency of electricity applied to chemical processes, has led to a very great simplification and cheapening of the manufacture, while with yet another class of products, such as copper and zinc, these methods have enabled materials to be prepared of a degree of purity unattainable by any other means. The electric furnace, in facilitating the production of a range of temperatures well beyond that attainable by any other known method, has thus inaugurated a new department of chemical industry. On account of the rapid progress of this branch of industrial electro-chemistry, it has until recently been generally overlooked that an extension of electrical methods of heating of no less importance has taken place in another direction, viz. in chemical and metallurgical operations, including those with both ferrous and non-ferrous metals for the production of heat at temperatures which are well within the range of ordinary fuel-heating methods.

Book Description
Excerpt from The Electric Furnace in Iron and Steel Production In the year 1879 the late Sir William Siemens, of London, patented a crucible form of electric furnace. In this furnace he was able with comparative ease to melt 10 kg. Of iron or steel by aid of the electric current in one hour. Fig. 1 shows the general arrangement and design Of this earliest crucible furnace for steel melting. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Electric Furnace: Its Construction, Operation and Uses On my first visit to Canada, in 1897, I constructed an electric furnace and showed it in operation at a lecture on Canada's metals, which was delivered by the late Sir William Roberts-Austen. The application of electrical heat to Metallurgy has always interested me greatly and I hope that this little book may serve to instil this interest in others, and to help forward the application of electric smelting in a country which is so rich in water-powers and mineral resources. This book originated in a series of papers, written about a year ago for the "Canadian Engineer," in which I endeavored to present, as simply as possible, the principles on which the construction and use of the electric furnace depend, and to give an account of its history and present development. The original papers were written at a time when the experiments of Dr. Haanel, at Sault Ste. Marie, were attracting public attention, and a large section of the book has been devoted to the consideration of these and other advances in the electrometallurgy of iron and steel. I wish to thank all who have helped me in the preparation of this book, including Dr. Haanel, whose valuable monographs have formed the basis of my chapter on iron and steel, and to whom I am indebted for additional information on this branch of the subject; Prof J. W. Richards, who has taken an interest in my work, and whose book on "Metallurgical Calculations" has been of considerable assistance in writing the chapter on furnace efficiencies; Mr. E. A. Colby, who gave me information in regard to his induction steel furnace and a sketch for Fig. 25; Mr. Francis A. J. Fitzgerald, who supplied me with the data for Table X.; the editor of the "Electrochemical and Metallurgical Industry," who loaned the block for the frontispiece, and the International Acheson Graphite Company, who gave me information about their furnaces and lent the block for Fig. 40. I also wish to thank those of my personal friends who assisted me in the tedious work of proof-reading. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
