(I) The Tensile Strength of Blast-Furnece Coke

The purpose of this work is to examine the tensile strength of coke and to relate this to the properties of industrial coke.The indirect tensile test (I. T. T .) provides an experimentally simple method for ensuring tensile strength of brittle materials . It is based on the theory of stressed beams and use test specimens fabricated into rods rectangular section.The theory indicates that I. T. T. is the most suitable method for measuring strength of formed coke. But as th first step of the study the blast-furnace coke is cosidered in this paper.The experiment with blast-furnace coke specimens indicated breakage strengths between 5 and 120kg/cm2, average 40kg/cm2.It was concluded that although the tensile strength of industrially acceptable blast frunace cokes can vary widely the measurements correlate well with the micro strength which represents caking power, and tnat the distinct influence of apparent density of the cokes (determined from tneir weight and dimensions) upon their tensile strength.
