The Electroslag Melting Process

Description: "This Bulletin traces the development of the electroslag melting process from its modest beginnings to the present. Important basic mechanisms such as electrochemistry, thermochemistry, and heat transport are described. Since the choice of flux is a unique parameter in the electroslag process, two chapters are developed to this subject. Electroslag melting experience for reactive metals, base metals, ferrous alloys, superalloys, and the refractory metals, both inside and outside the Bureau of M… more
