Correlation analysis of key process parameters of rotary kiln based on grey correlation degree

In the era of big data, the cement industry needs to use big data for correlation analysis. Combined with big data analysis technology, it can provide more scientific basis and more accurate characteristic information for the effective control of the temperature of cement rotary kiln. According to the characteristics of cement production in our country, according to the extraction of the key parameters of the process of rotary kiln production calcining and combining with the actual operator experience, the most important and most relevant process parameters are extracted to help operator find the most important parameters with strong correlation between the complex parameters, and help operator to change according to the correlation coefficient between parameters. Combined with the process flow to better judge the production.
