Description

Technical Field

[0001] The present invention belongs to the technical field of cement production, and particularly relates to a raw material batching method for reducing the cost and ensuring the quality of cement Background Art

[0002] In the traditional cement production process, the optimization of raw material batching mainly relies on experience or static ratio schemes, and it is difficult to dynamically adjust to adapt to fluctuations in raw material composition and changes in process conditions.

[0003] Especially when using industrial by-products (such as papermaking white mud) to replace part of the raw materials to reduce costs, the existing methods often face the following problems:

[0004] 1. The incorporation amount of papermaking white mud lacks scientific regulation, resulting in unstable clinker strength;

[0005] 2. The synergistic effects of key parameters such as raw material fineness and sintering temperature with the white mud content have not been quantified, easily causing increased energy consumption or quality fluctuations.

[0006] Therefore, there is an urgent need for a new raw material batching method that can dynamically adjust the content of papermaking white mud and balance cost and quality. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the present invention provides a raw material batching method for reducing the cost and ensuring the quality of cement, which solves the above problems.

[0008] To achieve the above object, the present invention is realized through the following technical solutions: A raw material batching method for reducing the cost and ensuring the quality of cement, comprising the following steps:

[0009] Obtain the content of papermaking white mud, raw material fineness, sintering temperature, and clinker strength in the current raw material ratio;

[0010] Perform dimensionless processing on the raw material fineness, sintering temperature, and clinker strength to generate a raw material fineness index, a sintering temperature index, and a clinker strength index;

[0011] Construct a papermaking white mud content adjustment model, import the raw material fineness index, sintering temperature index, and clinker strength index into the constructed papermaking white mud content adjustment model to obtain a papermaking white mud content adjustment coefficient;

[0012] Construct a target papermaking white mud content model based on the current content of papermaking white mud and the white mud content coefficient obtained from the papermaking white mud content adjustment model, and import the current papermaking white mud content and the white mud content coefficient into the papermaking white mud content adjustment model to output the target papermaking white mud content.

[0013] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0014] Further technical solution: re - proportion the starting raw material formula according to the target papermaking white mud content, and the starting raw material includes: papermaking white mud, limestone, clay, iron powder, and siliceous corrective material.

[0015] Further technical solution: the raw material is proportioned by weight as follows: 15% - 40% of papermaking white mud, 40% - 65% of limestone, 8% - 15% of clay, 3% - 5% of iron powder, and 0% - 5% of siliceous corrective material.

[0016] Further technical solution: the specific steps for dimensionless processing of the fineness of raw material, sintering temperature, and clinker strength to generate the fineness index of raw material, sintering temperature index, and clinker strength index are as follows:

[0017] Obtain the historical mean and standard deviation of the parameters of the fineness of raw material, sintering temperature, and clinker strength, subtract the current parameter from the historical mean of the parameter and then divide by the standard deviation of the parameter, so as to obtain the fineness index of raw material, sintering temperature index, and clinker strength index.

[0018] Further technical solution: the specific steps for obtaining the adjustment coefficient of papermaking white mud content are as follows:

[0024] Import the current papermaking white mud content and the white mud content coefficient into the papermaking white mud content adjustment model to output the target papermaking white mud content;

[0025] The papermaking white mud target content model is expressed as:
