DOWNLOAD EBOOKMetal casting component are found in 90 percent of manufactured goods and equipment, from critical components for aircraft and automotive industry to home applications. However, molten metal used to produce metal casting in practice generally contains impurities and inclusions which are deleterious to final cast metal product. Currently, filtration technique by using ceramic foam filter has been accepted as a successful method of reducing inclusions from molten metal during the casting of metal parts. The present research has been done to fabricate and improve a ceramic foam filter for using in filtration of molten metal, especially aluminium based alloys. It is an objective of the present innovation to provide a ceramic foam filter characterized by cost of raw materials. Ceramic foam filters are produced by impregnating polyurethane foam with ceramic slurry, drying, baking and finally firing the foam in the oven. Experimental tests were carried out to the filters to measure dimensions, weight, cold compression strength, and permeability properties before pouring process. After pouring process, the filter was cut into several sections to measure the macro and microstructure of the filter and ensure that impurity particles captured by a filter. Thermal shock properties, obtained from pouring liquid aluminium when filter was placed in the gating system to ensure that the filters could withstand temperatures of aluminium alloys. Further experiments were carried out to investigate and determine the efficiency of produced ceramic foam filter on quality of cast products. The result obtained in this investigation, the mechanical properties for aluminum LM6 alloy sand casting increased when ceramic foam filter was inserted into the gating system. A produced filter by using new materials is economical to be produced. Further more, the analysis data shows present innovation filter which can be made in any shape and size, has excellent thermal shock resistance, adequate compressive strength, acceptable density and permeability properties.

DOWNLOAD EBOOKThe Foseco Ferrous Foundryman's Handbook is a practical reference book for all those concerned with making castings in any of the commonly used alloys, by any of the usual moulding methods. International SI units are used throughout, but in almost all cases conversions to the more familiar Metric and Imperial units are given. Wherever possible, Casting Alloy Specifications include equivalent specifications for several countries as well as international specifications. Individual chapters cover the casting of light alloys, copper-based alloys, all types of cast-iron and steel. For each group of alloys, specifications and typical applications are described, together with details of melting practice, metal treatment and casting practice. Sand moulding materials, including green sand and chemically bonded sands are also included.

DOWNLOAD EBOOKThis open access book covers novel techniques and materials for removing inclusions in metallic melts, resulting in significant improvements to the purity, quality, and materials properties of the cast metal product. It looks at an entirely new generation of intelligent filter materials and filter systems with functionalized surfaces for removing solid and liquid inclusions such as deoxidation products, sulfides, and nitrides carbide from metallic melts. This collection of contributed chapters addresses the overarching goal of the production of lightweight structures and high-demand construction materials within an overall substantially cleaner and more sustainable global supply chain. The chapters cover a diverse array of topics ranging in scope from the development of ceramic foam filters, to in-situ x-ray and optical characterization techniques, as well as advanced modelling of 3D-printed filter structures. Additionally, the book features a number of contributions directly transferable to industrial applications related to the clean metal casting technologies of aluminium and steel alloys.
