Abstract
(1) THE authors of this book are respectively the steel-maker and works manager at one of the large Sheffield steel works, and their book is dedicated to the workmen in appreciation of their efforts to reach the ideal in actual work. They state that a considerable part of it was prepared for teaching purposes, and that the manuscript sheets have been freely criticised by men whose business it is to make steel ingots. As they point out, there is no way of studying the conditions which lead to the production of good and bad ingots more instructive than that of making ingots themselves, according to well-defined variations of the processes of ingot-making, and cutting- or breaking them in order to observe their qualities. In former days a good opportunity for such observations was enjoyed at negligible cost by the crucible steel melter, when ingots were "topped "down until the pipe or other evidences of unsoundness were broken away. Such a man knew what the conditions of casting were; he was familiar with the state of the ingot mould; he saw daily perhaps from twenty to forty ingots “topped” down to nearly half their length, and his eye was trained to notice minute differences in the appearance of the fractured surfaces. Such opportunities scarcely exist to-day, because ingots are only rarely “topped.”
