Abstract Time is one of the basic parameters of multi-dimensional mass flow,which has an important influence on the dynamic and orderly operation,dynamic precise design,restructure and optimization of the steel manufacturing process. Taking the ironmaking-steelmaking interface of a case plant as an example,a robust statistical method that takes median and robust coefficient of variation as the main statistical indexes was adopted to analyze the concentration and dispersion characteristics as well as its influencing factors of the mass flow time fluctuation. The results show that in the mass flow process,time concentration indexes and time dispersion indexes of each operation stage are quite different,which are mainly related to the content of the operation itself and the independence of the main objects. However,the time concentration indexes of each waiting stage are also different,while the differences among the time dispersion indexes are relatively small,which are comprehensively affected by the system structure and production organization. The production characteristics of each subprocess,the static physical structure of the process,and the dynamic running program of the mass flow are the main factors influencing the time fluctuation characteristics of the multi-dimensional mass flow.

Key words： steel manufacturing process ironmaking-steelmaking interface multi-factor mass flow time robust statistic method
