Available in PDF, EPUB and Kindle. Book excerpt: Investment bi-metal casting is a newly developed casting process and is prone to have more defects. Process optimization based on a computer simulation model is critical to obtain high quality castings. To obtain an accurate defect prediction analytically in the bi-metal casting part relies on the full consideration of the entire physical phenomenon during the process. It is also important to reduce the simulation time cost of the optimization process in order to make it practically achievable. This dissertation first presents the methods to develop a representative computer simulation model of the investment bi-metal casting process to predict the existing defects, such as: cracks, porosity, cold shut, hot tearing, deformation, etc. The model has been validated by experimental data. Secondly, this dissertation presents an integrated low time cost approach to optimize the investment bi-metal casting process based on the computer simulation model. As a case study, by employing the integrated optimization technology, an investment bi-metal casting process of a Spiral Flight is optimized to obtain better process specifications. The Monte Carlo analysis of the original and optimal process shows a significant improvement of the casting result.

This book was released on 2013-03-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: We come to know about the world in two distinctive ways: by direct perception and by application of rational reasoning which, in its highest form, is mathematical thinking. The belief that the underlying order of the world can be expressed in mathematical form lies at the very heart of science. In other words, we only know what we can describe through mathematical models. Casting of metals has evolved first as witchcraft, to gradually become an art, then a technology, and only recently a science. Many of the processes used in metal casting are still empirical in nature, but many others are deep-rooted in mathematics. In whatever form, casting of metals is an activity fundamental to the very existence of our world, as we know it today. Foundry reports indicate that solidification modeling is not only a cost-effective investment but also a major technical asset. It helps foundries move into markets with more complcx and technically demanding work. The ability to predict internal soundness allows foundries to improve quality and deliveries, and provides the information required to make key manufacturing decisions based on accurate cost estimates before pattern construction even begins. The acceptance of computational modeling of solidification by the industry is a direct result of the gigantic strides made by solidification science in the last two decades.
Download or read book METAL CASTING written by B. RAVI and published by PHI Learning Pvt. Ltd.. This book was released on 2005-01-01 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Investment casting process, or the lost wax process. Is a manufacturing method for alloy-based parts of many industrial and commercial applications. It offers a high degree of precision in regard to dimensions as well as excellent surface finishes. The process gets more complicated and prone to defects when bi-metals are involved. Since it is relatively complex and expensive compared with other casting processes (e.g., sand, permanent mold, etc.), total reliance on the old-fashioned trial-and-error approach to selecting various process parameters is generally found to be tedious, time-consuming, expensive and inadequate. In recent years computer simulation of the process has begun to complement the experience-based approach in meeting the demands of high quality investment cast parts in a cost-effective manner. This dissertation presents an integrated technology of optimizing investment bi-metal casting process and every closely related subjects, such as empirical design rules, CAD/CAE software and finite element method process simulation. The current state of technical affairs relating to CAD/CAE software, finite element algorithms, defect analysis and empirical rules of investment bi-metal casting process is reviewed, considering theoretical as well as application oriented aspects. As a case study, by employing the integrated optimization technology, an investment bi-metal casting process of Spiral Flight is optimized to obtain better process specifications that can eliminate or greatly reduce the existing defects. The dissertation ends with a discussion of future trends in optimization technology of investment bi-metal casting process.

Available in PDF, EPUB and Kindle. Book excerpt: Some rules for numerical simulation of the directional solidification process with steep temperature gradient were investigated. In order to improve the accuracy of calculation, the effect of the term (del k/del T) (del T/del Z) squared in the heat transfer equation on the outcome with steep temperature gradient is discussed. Problems such as how to treat latent heat of solidification, thermal properties at the casting/mold interface and the initial condition are also analyzed. Both finite difference and finite element methods were used to calculate the same casting under identical initial and boundary conditions with the same physical parameters. The results were compared.

This book was released on 2011-12-06 with total page 1640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical and numerical simulations make it possible for materials science to go from experience-based to science-based, and from qualitative to quantitative understanding. Physical simulations, which effectively reveal the underlying principles of a materials structure and property evolution, save significant amounts of time and money. Numerical simulations meanwhile permit descriptions and forms of material processes which are impossible to achieve experimentally. Both types of simulation are naturally gaining acceptance worldwide, and will become a prominent approach used in materials research in the 21st century. Young researchers will therefore benefit greatly from studying this volume.

Download or read book Directional Solidification of Steel Castings written by R. Wlodawer and published by Elsevier. This book was released on 2013-10-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Directional Solidification of Steel Castings summarizes the results of a large number of investigations, mostly scientific in character, on the directional solidification of steel castings. The influence of design on the technical possibilities of producing casting in the foundry is examined. Diagrams, simple basic rules, and formulae are provided, along with many practical examples. This book is comprised of 16 chapters and begins with an introduction to the technical and psychological aspects of steel casting before turning to a discussion of the influence of shape and dimensions on the time it takes for castings to solidify. The thermal gradient, feeder heads, and cavities in steel castings are then considered. In particular, the effect of the thermal gradient on solidification and feeding range are examined. Methods for increasing the thermal gradient in the casting are described, including the use of mold heating pads, breaker cores or Washburn cores; external cooling (iron chills); cooling fins; internal chills; and exothermic pads. Cavities in steel castings which are commonly mistaken for true shrinkage cavities are also analyzed. This monograph is particularly suitable for foundry managers, foremen, technicians, casting designers, and students.
