The metal casting, uses large amounts of natural resources, energy and metals as well as generates significant amounts of gases and solid wastes, which have an essential influence on the natural environment and work conditions in casting houses. The condition of the further development is the adjustment to the strategy of the sustainable development.This book examines potential solutions to the economic, ecological, and occupational hazards generated by the foundry industry. It focuses on emissions of chemical compounds during the preparation and formation of molding sands, molds pouring with molten metal, molds cooling and castings knocking out. It also addresses the effects of the spent molding sands reclamation process and the influence of spent sands on the environment during their storage. Establishing the most sustainable techniques for limiting the negative impact of foundry processes on the environment is explored in detail. The book will be valuable to academics and industry professionals alike. Describes the mechanisms of hardening and thermal destruction of individual binders in moulding and core sands; Assesses the influence of moulding and core sands technology on the environment; Discusses state of the art moulding and core sand technology.

This book presents a scientific approach to metal casting design and analysis supported by software tools. Unlike other books in metal casting focused only on the process know-how, this book uncovers the know-why as well. Besides serving the needs of students of mechanical, production and metallurgical engineering, this book is equally meant to benefit practicing engineers involved or interested in casting development, including product designers, toolmakers, foundry engineers, supply chain managers, engineering consultants, researchers, and software developers. The theory discussed in the book is applicable to all types of castings: ferrous and non-ferrous, produced in sand and metal moulds. By gaining a better understanding of the theory and logic involved through creating, analysing and optimizing virtual castings, the readers will learn how to: Design process-friendly cast products, leading to shorter development time Manufacture assured quality castings, leading to fewer rejections and 'surprises' Manage material and energy utilization, leading to higher yield and lower costs.

This book provides an overview of the surface effects at the interface boundary of metal/sand moulds, and their influence on the surface quality, microstructure and mechanical and anticorrosive properties of high-quality cast iron. It explores utilitarian aspects of the production of high-quality cast iron castings, including thin-walled castings of high-quality cast iron alloys, and examines problems related to the determination of moulding sands and reclaim quality, and their influence on castings. Presenting new material, this book takes into account the influence of metal quality, pouring temperature, solidification time, the quality of moulding sand with the reclaim application, as well the binders of moulding sands, on the formation of the degenerated graphite near surface layers. It also employs the latest research methods, such as a wavelength-dispersive spectrometer (WDS) analysis and thermodynamic calculations, which were carried out on the reactions occurring in the study area. Providing a valuable resource to academics and researchers interested in materials science, metal casting and metallurgy, this book is also intended for metal industry professionals.

Engineering Equipment for Foundries covers the proceedings of the Seminar on Engineering Equipment for Foundries and Advanced Methods of Producing such Equipment, held in Palais des Nations in Geneva, Switzerland on November 28-December 2, 1977. This seminar is organized by the United National Economic Commission for Europe. This book is organized into five parts encompassing 39 chapters. Part I focuses on the economic problems of the foundry industry, particularly in connection with reduction of labor requirements and in calculating foundry production capacity. Part II highlights the problem of environmental pollution created by different branches of metallurgy, while Part III deals with the general problems concerning practices and technological developments in the foundry industry. Part IV describes the technological advances in molding and coremaking processes in foundry. This part also discusses the reduction of waste energy in permanent mold and die-casting foundries. Part V considers the transition to process and production automation of foundry equipment. This book will prove useful to metallurgical engineers, manufacturers, and researchers.
