Available in PDF, EPUB and Kindle. Book excerpt: A laboratory mold and experimental procedure were developed for unidirectional solidification of AISI 4340 low alloy steel by Electroslag Remelting (ESR). Major emphasis was to control solidification structure by developing methods to control and study factors affecting the important thermal variables. The effect of power input, current density, slag depth, and electrode diameter on electrode melting rate, temperature gradient in the liquid, G (sub L), and isotherm velocities, R, were studied and related to structure. Electrode and slag cooling were employed to enable achieving increased G (sub L)/R. Electrode melting rate is the main parameter affecting the important thermal variables. The structure of the ingots was found to be compatible with thermal measurements. Finally, a computer heat flow model was developed to predict metal pool shape and depth, and other important thermal variables for different operating conditions. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Dr. Boris Medovar, a member of the Soviet Academy of Sciences, is a promi nent member of the E.O. Paton Electric Welding Institute in Kiev, one of the pre-eminent institutes of the USSR. The Paton Institute, internationally famous for its entrepreneurial efforts in electrical welding processes, is also famous for its application of electrically based processes in melting and remelting of high alloy and high-temperature materials. These include the ESR (electroslag re melting) process, the ESC (electroslag casting) process, skull remelting based on electron-beam processes, plasma arc processes, and electric arc processes. Along with the ESR process for ingot production is the commercial plasma arc remelt process for specialty steels, particularly where high nitrogen contents may be desired, as in austenitic stainless steels. Major industrial centers are now scattered throughout the USSR and are a major factor in high-alloy, high strength, low- and high-temperature materials. The ESR process was developed in response to the Western development of the VAR (vacuum arc remelting) process for producing very highly alloyed materials during the growth period of the jet engine age. The V AR and ESR processes utilize different purification and refinement processes that are extremely critical in very highly, complexly alloyed superalloys and high-speed tool steels. In water-cooled remelt systems, they also achieve relatively rapid (directional) solidification, minimizing segregation and coarse phase separation of undesir able impurity elements or elements that tend to form coarse brittle phases.
Download or read book Electroslag Remelting Towards Clean Steel written by Chengbin Shi and published by Springer Nature. This book was released on 2023-06-22 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the results that the authors have achieved on the study of functional principle of electroslag remelting for production of high-quality clean steel. The dependence of oxygen, sulfur, and non-metallic inclusions on the processing parameters of electroslag remelting is assessed. The fundamentals and technologies of clean steel production by electroslag remelting have been applied in the round to discuss oxygen, sulfur, and non-metallic inclusions evolution and control. A general concluding remark and a perspective for future work are present. The book is likely to be of interest to university teachers, researchers, R&D engineers, and graduate students in material processing and pyrometallurgy who wish to explore innovative technologies that lead to more energy-efficient and environmentally sustainable clean steel production.

Available in PDF, EPUB and Kindle. Book excerpt: Electroslag remelting of gun steel has been proposed as an alternate manufacturing process because of reported improvements in mechanical properties and potential economic benefits. These improvements are a result of the effective control of the many variables inherent in the process. In order to obtain a uniform microstructure while avoiding piping, porosity and macrosegregation, a unidirectional solidification mode is desired(1). This mode of solidification, together with the relatively short holding times of the molten metal, also affects the distribution of second phase particles, for example, it results in a more uniform carbide distribution because the carbides are not allowed to grow in the transverse or longitudinal directions.
Download or read book Computational Thermo Fluid Dynamics written by Petr A. Nikrityuk and published by John Wiley & Sons. This book was released on 2011-09-19 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining previously unconnected computational methods, this monograph discusses the latest basic schemes and algorithms for the solution of fluid, heat and mass transfer problems coupled with electrodynamics. It presents the necessary mathematical background of computational thermo-fluid dynamics, the numerical implementation and the application to real-world problems. Particular emphasis is placed throughout on the use of electromagnetic fields to control the heat, mass and fluid flows in melts and on phase change phenomena during the solidification of pure materials and binary alloys. However, the book provides much more than formalisms and algorithms; it also stresses the importance of good, feasible and workable models to understand complex systems, and develops these in detail. Bringing computational fluid dynamics, thermodynamics and electrodynamics together, this is a useful source for materials scientists, PhD students, solid state physicists, process engineers and mechanical engineers, as well as lecturers in mechanical engineering.
