Abstract

The invention discloses a raw cement material quality control method and system based on a generalized inverse matrix. The method comprises steps as follows: S1, determining a target value expected by raw cement material quality; S2, determining the required proportion of all raw materials in a raw cement material and giving the relation between the raw materials and effective ingredients; S3, calculating the corresponding relation between the expected target value and the raw materials by using a generalized inverse matrix theory according to the raw materials, the effective ingredient content and the expected target value; S4, adjusting the proportion of the raw materials by using the corresponding relation obtained in Step 3 according to a coefficient matrix of the corresponding relation among the expected target value, a given target value and the effective ingredients as well as a coefficient matrix of the effective ingredients contained in the raw materials. According to the method, the proportion of the raw materials is calculated according to the given target value, the stability of ingredients of the ground raw material is guaranteed, batching requirements under different process conditions are met, the proportion of the raw materials is adjusted in real time, the raw material rate fluctuation is reduced, and the quality of the raw materials and the robustness of the whole raw material quality control system are guaranteed.

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...
