✦ Synopsis

Using the diametral compression method, tensile strengths were determined for 44 cokes, produced in a small pilot oven, from two-and three-component coal blends based on six coals varying in International Classification from 332 to 733. The textural composition of cokes from single-coal charges were determined by point-counting during the examination, in a scanning electron microscope, of etched coke surfaces. The data were used in conjunction with the blend compositions to calculate the textural compositions of the coke from the blended-coal charges. Coke tensile strengths and calculated textural data could be closely related by an equation derived by multi-linear regression analysis. This approach can be used to predict the tensile strength of cokes made from multi-component blends.
