用x射线衍射法测定焦炭(002)晶面间距d(002),将其代入本文提出的焦炭石墨化程度的合理表达式,即可得到冶金焦炭石墨化程度。用此法对国内部份冶金工厂焦炭石墨化程度进行了测定,并用燃烧法测定焦炭热值与用焦炭石墨化程度测定值计算出的焦炭发热值对比,误差<3%,证明了用x衍射法测定热炭石墨化程度方法是可行的。 The degree of graphitization of metallurgical coke can be obtained by measuring the d (002) interplanar spacing of coke (002) by x-ray diffraction and substituting it into the reasonable expression of coke graphitization proposed in this paper. This method was used to measure the degree of graphitization of coke in some domestic metallurgical factories. The comparison of calorific value calculated by the combustion method with that measured by the graphitization degree of coke showed that the error was <3% Method to determine the degree of thermal graphitization is feasible.
