A method and system for quality control of cement raw meal based on generalized inverse matrix

Abstract

A method and system for quality control of cement raw meal based on generalized inverse matrix, the method includes the following steps: S1: determine the expected target value of cement raw meal quality; S2: determine the required ratio of various raw materials in cement raw meal, and give The relationship between raw materials and their active ingredients; S3: According to the raw materials, active ingredient content and expected target value, use the generalized inverse matrix theory to calculate the corresponding relationship between the expected target value and raw materials; S4: According to the expected target value, given target The coefficient matrix of the corresponding relationship between the value and the active ingredient, and the coefficient matrix of the effective ingredient contained in the raw material, use the corresponding relationship obtained in step S3 to adjust the ratio of the raw material. The present invention calculates the ratio of raw materials according to the given target value, ensures the stability of the raw meal components after grinding, meets the batching requirements under different process conditions, realizes the real-time adjustment of raw material ratios, and reduces the ratio of raw materials Value fluctuations ensure the quality of the raw meal and the robustness of the entire raw meal quality control system.

Description

technical field [0001] The invention relates to a cement raw meal batching method and system, in particular to a cement raw meal quality control method and system based on a generalized inverse matrix, belonging to the technical field of cement production technology. Background technique [0002] The cement production process can be briefly summarized as "two grindings and one firing", in which "two grindings" refers to grinding raw materials into raw materials and clinker grinding into cement, and "one firing" refers to calcining raw materials to form mature cement. material. The whole process is a typical continuous process, the quality of the previous stage has an important impact on the quality of the next link, and raw material powder into raw material is the most important link in the whole cement production, the composition of raw material determines the three rate value and other components Whether the indicators (such as Fe2O3) are qualified is the premise to ensur...

Problems solved by technology

Its disadvantages are: adjusting by experience instead of strict calculation, its subjectivity is relatively large, and the effect of adjustment is difficult to guarantee; in addition, in the actual production process, the raw material composition will fluctuate in general, sometimes the fluctuation is relatively large, according to each The results of the hourly sampling laboratory are adjusted, and the fluctuation of the raw material rate value will be relatively large
