Physical Strength Tests on Coke Fed to and Withdrawn from Blast Furnaces

摘要

The complex pattern of the breakage of coke during rotation within a micum drum has been shown to follow closely a single mathematical expression, which may be expressed in a logarithmic or differential form, and consideration has been given to the possible use of one of the coefficients of this expression as a measure of the physical strength of the coke, characterizing the breakage throughout an extended drum-test. The changes in this coefficient have been noted after a number of exercises in which a study was made of coke fed to and withdrawn from blast furnaces. Such coefficient changes, between the values noted for feed and tuyere samples, have been shown to be directly related to changes in a number of chemical and physical properties of the coke, namely ash, iron, sodium, and potassium contents and also true relative density.
