Analysis on calculation method of continuity degree for metallurgical manufacturing process
Due to the complexity,synergy,and integrity of the dynamic operation of metallurgical processes,it is diffi-cult for evaluation methods based on processes or equipment to analyze the overall operational status of the process.Academician YIN Ruiyu,starting from the perspective of the overall operation of open dynamic systems,uses"time"as the basic parameter for analysis and proposes a key indicator to characterize the dynamic operation of processes-the continuity degree.To study the statistical calculation and improvement methods of continuity degree based on actual production data from metallurgical processes,a graphical representation method for the continuity degree was proposed.Mathematical analysis and derivation were conducted for the two statistical methods of continuity degree based on time-order average and batch average within the industry.The results show that when the total running time of the material flow of each batch of products is constant,the two calculation methods are equivalent.When the total running time is not constant,the continuity degree statistical method based on time order average is more in line with the statistical results of continuity degree,and its relationship with the main influencing factors is more deter-mined and can be transformed into a linear relationship.It is more suitable for analyzing the continuity degree of ac-tual production lines.The difference in the total running time of material flow among batches of products,that is the diversity of product specifications or process paths in actual production,is an important factor affecting the degree of process continuity.The smaller the difference in total running time of material flow,the higher the degree of process continuity.
