| 摘 要： | 以研究炼焦煤性质与焦炭反应性、反应后强度之间的数学关系为目的，通过胶质体和中间相形成动力学解析导出模型的主要影响因子，以煤的变质程度、煤岩组成、粘结性、灰分及K2O和CaO含量等因素为自变量，由25种工业用煤的炼焦试验，建立出预测模型，并得出壳质组使反应性增大及反应后强度降低；K2O催化作用强于CaO，且两者的催化作用均随煤的变质程度不同而不同等重要结论.

| Abstract: | The mathematic relationship between coking coal's characters and coke reactivity index (CRI) and coke strength after reaction (CSR) was studied.Main effect factors were analyzed by dynamics model formed by metaplast and mesophase.Taking metamorphic degree of coal, coal maceral, caking property, ash and the content of K_2O and CaO as independent variable, forecasting model was set up by the coking tests with 25 kinds of coals used in the industries.It concludes that exinite in coal makes CRI increase and CSR decrease; the catalysis of K_2O is higher than one of CaO; the catalysis of K_2O and CaO is different with the difference of metamorphic degree of coal. |
