Analysis for Continuation Degree of Steelmaking-Continuous Casting Process
摘要
Continuation degree is one of key indicators to measure the material flow efficiency in steelmaking-continuous casting process, which is characterized by time distribution patterns. According to the production data of a steelmaking enterprise in China, the central tendency and discretization degree of time parameters for each operational stage in steelmaking-continuous casting process (SCCP) are analyzed, and influence factors on time distribution are explored in this paper. Analysis results show that the time distributions among intermediate stages are significantly different. The mean production time of Ladle Furnace (LF) refining stages is longest, and the fluctuation of production times is the greatest than ones of other stages, which are the important factors to affect the continuation degree of steelmaking process. The fluctuation of production time of LF refining stage is caused by heating and soft stirring, and the influence of heating is more significant. In addition, the refining process path, steel grade, and temperature are also important effect factors. The results can provide valuable insights for optimizing steelmaking-continuous casting operations and improving the continuity and stability of production process.
