Embodiment Construction

[0052] The present invention will be described in detail below, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0053] The calculation model of sintering ingredients includes the following steps:

[0054] 1) The calculation model of sintering ingredients is a multi-constraint and multi-objective calculation model:

[0055] In the batching process, the iron grade Tfe, basicity R, and silica SiO of the sinter ore 2 , calcium oxide CaO, aluminum oxide Al 2 o 3 , Magnesium oxide MgO as a reference index, the calculation formula of target iron grade Tfe:

[0056]

[0057] TFe composition percentage content in sinter = ∑x i *A TFei (2)

[0058] Percentage content of sintered ore after burning loss and dehydration=∑x i *(100-A ilg )*(100-A iH2O ) (3)

[0059] In formula (2) and formula (3): x i Indicates the ratio of the i-th raw material; A TFei Indicates the percentage of TFe composition...

Abstract

The invention relates to a calculating model for sintering and burdening. The calculating model is characterized by comprising the following steps: restraining burdening top and bottom limitations as well as chemical component top and bottom limitations and taking iron grade and basicity as a target; adopting a fuzzy theory to establish a fuzzy satisfaction function; in a burdening process, respectively establishing an iron grade satisfaction function and a basicity satisfaction function of sintered ore according to the burdening characteristics and process requirements; re-establishing a penalty function to construct a fitness function; performing algorithm iteration. The calculating model has the advantages of randomly generating a plurality of groups of proportions, calculating an adaptive value of each group of proportions through the fitness function, and comparing to obtain an individual optimal proportion and an overall optimal proportion. Under the guiding of the individual optimal proportion and the overall optimal proportion, each group of proportions is updated to finally obtain the optimal proportion which meets all restraints. The proportion optimization to raw materials is realized, the chemical components and the metallurgical performances are met, and the blast furnace smelting requirements are met.

Description

technical field [0001] The invention relates to a sintering batch calculation model. Background technique [0002] The iron and steel industry is still developing rapidly, and the society advocates to adhere to the road of sustainable development. Therefore, improving the quality and efficiency of the iron and steel industry has become a development strategy for iron and steel enterprises. Due to the constant changes in the price of iron ore in the international market, domestic iron and steel enterprises will make adjustments to the types and proportions of iron ore. In the case of changes in the type and grade of iron ore, what kind of batching scheme to use for batching can improve the quality of sintered ore and reduce costs, which is of great significance to the iron and steel industry. [0003] Sintering batching is the first process of sintering production, and the quality of batching scheme will directly affect the quality of sinter ore, and then affect the producti...
