摘要
为准确预测焦炭质量,采用MSS2000全自动智能型煤焦显微分析系统,测定炼焦煤样的煤岩组分、活惰比和镜质组平均最大反射率,分析煤样所制备焦炭的质量。采用SPSS软件建立基于煤岩参数的焦炭质量预测模型。模型验证结果表明,焦炭的抗碎强度、耐磨强度、化学反应性、反应后强度与煤岩组分和镜质组平均最大反射率的复相关系数均大于0.879,P值小于0.01。预测模型可信度较高,为焦化厂优化配煤、提高焦炭质量提供了参考。
This paper seeks to obtain an accurate prediction of coke quality. The research involves measuring coal components,ratio of reactive and inert components,and average maximum vitrinite reflectance( R—max) of coking coal using MSS2000 Automatic Intelligent Coal Particle Microanalysis System; analyzing coke qualities of as-prepared coking coal samples; and thereby using SPSS software to build a coke quality prediction model based on coke parameters. The verified results demonstrate that the prediction model owes its higher reliability to the multi-correlation coefficient greater than 0. 879 between the coke crushing strength,abrasion strength,chemical reactivity,and coke strength after reaction and coal components and average maximum vitrinite reflectance,and to P value less than 0. 01. This model may provides a reference for optimizing coal blending and improving coke quality.
