Scaling of Steel at Heat-Treating Temperatures delves into the intricacies of these operations, emphasizing the conditions that trigger reactions between steel and furnace atmospheres. It explores how factors like temperature, time of exposure, gas flow velocity, and the introduction of sulfur-bearing gases influence steel scaling. The book is organized into three key investigative phases: the impact of temperature and oxidizing agents, the influence of gas-air combustion atmospheres, and the role of sulfur dioxide. Detailed insights are provided on the detrimental effects of scaling, such as metal loss, dimensional changes, and increased costs due to additional scaling removal processes. The book also covers foundational theories and historical research on oxidation of iron, offering a thorough survey of literature and previous studies. The methodologies, apparatus, and experimental procedures used in this investigation are meticulously explained, providing a valuable resource for those in the field of steel treatment and engineering research.
