Abstract

The renewed worldwide interest in the microscopic study of blast-furnace coke has resulted in the emergence of a variety of classification systems and criteria for describing coke microstructure, particularly coke microtexture or carbon forms. This paper briefly reviews the historical work in the field of coke petrography and describes the U.S. Steel coke carbon form classification system in detail. Emphasis is placed on relating coal petrographic analysis (coal rank, coal type) to the observable and quantifiable microscopic features of the coke produced. Additionally, the methods employed by U.S. Steel for carbon form analysis and the application of coke petrography to plant problem solving are discussed. This paper was presented at the 25th Meeting of North American Coal Petrographers on November 18, 1983, in Merrillville, Indiana, and is being submitted for publication in The International Journal of Coal Geology.
