The invention discloses a method for automatically adjusting the target value of the neutron system based on cement elements. Combining the historical clinker full analysis value and strength value, the clinker rate value target value is kh 标 、sm 标 、im 标 , combined with the error calculation of the clinker rate value of the fluorescent system, the set value of the clinker rate value written to the raw material ingredient calculation system is kh 配 、sm 配 、im 配 , and then obtain and carry out theoretical calculations based on the set value of clinker rate, clinker heat consumption, chemical composition of coal ash, raw coal calorific value, and chemical composition of raw materials, and obtain the target value of raw meal rate KH 理 , SM 理 , IM 理 , and then collect the quality data of raw meal and clinker in the production process, use the analysis software of raw meal and clinker quality data to analyze and model, and carry out control; finally, output the clinker rate value setting of the raw material batching calculation system for the next period value to get the target value of raw material ratio. The present invention automatically considers all errors and accurately locates the target value of the neutron rate value, realizes the alignment of the coal material in the production process, reduces the fluctuation of the clinker rate value, optimizes the thermal system in the kiln at the quality end, and improves the strength of the cement clinker.
Description
An Automatic Adjustment Method of Neutron Subsystem Target Value Based on Cement Elements technical field The present invention relates to cement production technology field, especially relate to a kind of neutron system target based on cement element Value auto-adjustment method. Background technique Existing cement plant raw material proportioning is to adjust raw meal target value according to fluorescence result, batching calculation, now In the existing technology, the ratio adjustment of the raw coal and raw materials in the process of changing the pile completely depends on the responsibility of the duty position and the experience in ratio adjustment. Job competencies are uneven, and the chemical composition of the production process will inevitably fluctuate greatly. In recent years, with the on-line detection of cement elements The application of control technology and fully automatic fluorescence detection technology in the cement industry has solved the ...
