Production Of Standard-Grade Ferromanganese In An Electric Arc Furnace, John P. Hager

Bachelors Theses and Reports, 1928 - 1970

The original purpose of this thesis was to determine the feasibility of producing standard-grade ferromanganese from the Cuban concentrates using an electric arc furnace. This purpose was later changed since it became necessary to study the adequacy of a laboratory electric arc furnace for comparability with commercial operations.

Since the original purpose of the investigation had been changed while the area of investigation had not, the research work was then continued with the purpose of collecting information on ferromanganese production as a background for anticipated future work in pyrochemical research at the Montana School of Mines.

The Reduction Of Chromium Oxide In A Vacuum Furnace, Raymond W. White

Bachelors Theses and Reports, 1928 - 1970

Interest in vacuum metallurgy has grown considerably in recent years. High vacuum techniques are of fundamental importance as research tools in defining the properties of pure metals, in the extraction and processing of reactive metals, and are becoming increasingly important in commercial metallurgical processes. Much of the work described in recent literature has centered on applications of vacuum to commercial annealing, degassing, distillation, and melting and casting processes.
