论文在实验室装置条件下,研究了焦炭的结构及其物理性质与煤的类型以及煤料加热速度、粉碎度和搗实程度的关系。确证,从33—37号单种煤和它们的配合物中在相同条件下所得的焦炭,其物质的抗破碎强度基本上无实质差别,唯有37号煤的焦炭物质强度例外而表现相当低。此外确证,焦炭的硬度有较显著的差别,并在很大程度上取决于煤的粘结性。另一方面却发现了焦炭的孔状体强度及其气孔性无论是随煤的类型和所指的物理条件的变化都有实质的差别;在物理条件中尤以搗实程度和加热速度对孔状体强度的影响最为显著。确立了焦炭孔状体强度的差别归因于其气孔率的不同和孔结构的各式各样以及煤粒间结合力的差别。
Under the conditions of laboratory installations, the paper studied the relationship between the structure and physical properties of coke and the type of coal, as well as the heating speed, grinding degree and compaction degree of coal. It is confirmed that the coke obtained from the single coals No. 33-37 and their complexes under the same conditions has substantially no significant difference in the anti-crushing strength of the material, except that the strength of the No. 37 coal has the exception of the coke material and the performance is quite low. . In addition, it is confirmed that there is a significant difference in the hardness of coke and depends to a large extent on the cohesiveness of coal. On the other hand, it has been found that the strength and porosity of the pores of coke vary substantially with the type of coal and the physical conditions referred to; in the physical conditions, the degree of compaction and the heating rate are particularly important for the pores. The effect of body strength is most pronounced. The difference in the strength of the coke pores was established due to the difference in porosity, the variety of pore structures, and the difference in bond strength between coal particles.
