IC 7851 Bibliography Of Model And Pilot-Plant Applications In Ferrous Metallurgy, 1945-56 ? Introduction

Reduced-scale models have long been used in hydrodynamics, aerodynamics, and heat transfer for studying fundamental flow relations or the performance of prototype designs under prescribed conditions. The pilot plant is a common tool of chemical engineering for investigating process variables and as an integral step in developing a new process. The metallurgical industry was rather slow to recognize the applicability of these techniques to some of its established and rather complex processes, but there has been a rapidly increasing number of applications of the principles of modeling in process metallurgy since World War II. Not only have pilot-scale operations been employed for developing methods of extracting metals that have recently achieved commercial importance, as well as new processes for some of the commoner metals, but models have also been used for engineering studies aimed at better understanding of the controlling, variables of time-honored conventional processes, It appears that the principles of similitude have become accepted as a useful tool, when properly applied, in metallurgy as in other fields of engineering. Much of the work of the Pyrometallurgical Laboratory, Region V, involves study of high-temperature smelting and refining processes for ferrous and related metals in pilot-scale equipment, such as the experimental blast furnace, converter, open-hearth, arc furnace, and rotary kiln. It was appropriate for the work of this laboratory that guiding principles for designing apparatus and interpreting results should be set down and that a bibliography of related work should be available for reference. A summary of the principles of model study and a brief review of some of the more noteworthy general papers have been published elsewhere.3/ Also, the Bureau of mines plans to publish a report of investigations describing its experimental work in this field. The bibliography is presented here as a service to others who may have use for it.
