内容説明
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."

内容説明
Electroslag technology is a special method of melting and casting steel and alloys that produces highly pure and very strong metals. The development of this method in the Soviet Union was an effort to catch up with the technology of Vacuum and Remelting (VAR) previously developed and tested in the US for complex, high alloy systems. Electroslag casting has become highly successful for a wide range of products and compositions. Currently, EST is used in the US, Europe, and Japan. The present book describes key applications of electroslag technology as well as a number of practical recommendations. It provides a discussion of the refining slags employed, their stability, refining abilities, etc, for an extremely wide range of alloys. Mechanical properties and the extensive equipment modifications that makes EST so attractive are discussed in detail. Everything from small castings to extremely large rotors, truck and equipment beds are reported. The book also covers the development of EST in other countries, including Austria, Germany, Canada, USA, France, Japan, Italy, Yugoslavia, Hungary, Czechoslovakia, and China.
This reference book on mechanics of materials, production engineering, material science, mining, metallurgy is intended for material research scientists, practical engineers in metallurgy and steel mill factories and national laboratories.
