This book provides a detailed analysis of the properties and testing of foundry moulding sands, which are used in the manufacture of metal castings. The book covers the composition of moulding sands, the physical and chemical processes involved in moulding, and the testing methods used to ensure the quality of the final product. It is a valuable resource for foundry workers, engineers, and anyone interested in the science of metal casting. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work is in the "public domain in the United States of America, and possibly other nations.

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.

Aeration sand filling is a new molding technique in foundry. Using this technique, sand with smooth flow can be filled in any orientation and shape using low-pressure air. This is not possible by conventional gravity and high-pressure blow filling techniques. Aeration was introduced as an energy-efficient and environmentally-friendly sand molding technique. In addition, aeration has its niche on quality of molds it could produce. Friability, one of the crucial green properties for the quality mold was significantly low in aeration in comparison to the gravity and high-pressure blow filling. The fluidization action in aeration acted upon the sand clay interfaces and created the interactions with them and induced better surface abrasive property. In other words, aeration lowered the friability in the green sand allowing a lower compactibility level in green sand molding, which was not possible with the conventional molding techniques. The range of 30-35% was suggested as the optimal working range of compactibility for aeration molding technique for selected sand and clay composition. Advance cone jolt and thermal erosion tester were developed and used to examine the green sand properties of the foundry sand. Advance cone jolt was sensitive to the clay composition and contamination in green sand, whereas thermal erosion tester demonstrated its relevance in evaluating mold surface behavior at an elevated temperature. Thermal erosion test displayed less sand erosion in the molds buit in the aeration. Green sand in aeration was benefited by the favorable clay orientation. Homogeneous and isotropic distribution of clay platelets occurred during fluidization, which produced a better clay coating on the sand grains and increased the grain to grain bonding. Scanning electron microscope displayed a uniform clay coating and univeral micro-tribometer showed greater bonding strength in the surface of the molds produced in aeration. Casting trial along with the relevant standard AFS tests for green sand properties were carred out, and analyzed using design of experiments and statistical tools.

Excerpt from 1 Elements of the Petrographic Study of Bonding Clays and of the Clay Substance of Molding Sands; 2 Mineral Composition and Texture of Clay Substance of Natural Molding Sands: 3 the Relationship Between the Physical and Mineralogical Characteristics of Bonding Clays It is frequently possible to work out the exact arrangement of the atoms within a crystal from the pattern of the emerging beams of x-rays. In recent years a large body of data has become available on the arrangement of the atoms within the various clay minerals. This work is providing, per haps for the first time, a fundamental, basic explanation of the physical properties of clays.
