摘要： PROBLEM TO BE SOLVED: To solve problems described below: it is known that indirect tensile strength of porous material such as coke is largely depending on porosity, and breaking of coke occurs at coarse pore, connected pore, site of thinned pore wall due to approximation of pores; however, such pores are generated by degassification of coal in the dry distillation process, hence adhesiveness of interface between coal particles and pore formation have no direct relationship and breaking points are not limited to a joint surface, therefore the indirect tensile strength is insufficient for adhesive strength evaluation; while an approach is made to estimate adhesive strength from the indirect tensile strength and porosity, but this method also can not be mentioned to avoid the problem on measuring strength actually.SOLUTION: This method for measuring adhesive strength of coal for producing coke comprises: compression molding coal finely-milled into predetermined particle size or smaller with such load as capable of maintaining the shape after compression molding; dry distilling the coal under inert atmosphere and coking; using the coked matter as a sample to be measured; measuring compression strength and the pressure at break is assumed as adhesive strength. It is preferable that coal is finely-milled into 75 μm or smaller, compression molded under pressure of 20 MPa or less, dry distilling under inert atmosphere, and using the dry distilled and coked matter as the sample to be measured.
摘要翻译：要解决的问题：为了解决下述问题：已知多孔材料如焦炭的间接拉伸强度很大程度上取决于孔隙率，并且焦炭的断裂发生在粗孔，连通孔，由于近似而变薄的孔壁的位置的毛孔; 然而，这样的孔是通过干馏过程中的煤的脱气产生的，因此煤颗粒之间的界面的粘附性和孔形成没有直接关系，断裂点不限于接合面，因此间接拉伸强度不足以用于粘合剂力量评估; 而从间接拉伸强度和孔隙度的角度来估计粘合强度，但是也不能提及这种方法以避免实际测量强度的问题。解决方案：用于测量生产焦炭的煤的粘合强度的方法包括：压缩将能够在压缩成形后保持其形状的负荷将成形煤精细研磨成规定的粒径或更小的颗粒; 在惰性气氛下干燥煤焦化; 使用焦化物作为待测样品; 测量压缩强度和断裂压力被认为是粘合强度。优选将煤精细研磨至75μm以下，在20MPa以下的压力下进行压缩成型，在惰性气氛下进行干蒸馏，使用干馏出的焦化物作为被测定样品。
