INTRODUCTION
IT is the author's firm conviction, that every engineer should have a basic knowledge of the metallurgy of iron and steel. Without the aid of these valuable metals civilization would indeed revert to the Stone Age. Not only the metal industry but all industries are dependent upon these metals for their existence.
A nation's industrial vitality is measured by its metal production, and the metal industry is often referred to as the pulse of American business. The production of pig iron alone is the basis for many business forecasts.
The metallurgy of iron and steel may be divided into three parts: process metallurgy, or the winning of the metal from its ores and the refining of the metal to a quality which will be of the best and most economical service to the industries that use it; mechanical metallurgy, or the processes of working steel, shaping it, and fabricating it into finished or semi-finished products; and the metallography and heat treatment of iron and steel, which deal with the properties of finished and semi-finished products and methods of improving them in order that they may be of the greatest possible service to industry.
The present treatise is an attempt to introduce all of these subjects to the reader in a concise form, and special emphasis has been placed upon the subject of ingots and ingot making, since a knowledge of this subject is necessary for an understanding of the difficulties encountered in the rolling-mill and heat-treatment departments. An endeavor has been made to bring up to date the subject of electric furnaces for the iron and steel industry and the
