Abstract

The invention discloses an optimized ore blending method based on sintering-pelletizing-ironmaking linkage, and belongs to the technical field of optimized ore blending before ironmaking. The method comprises the steps: 1, building a model, building a molten iron cost calculation model, wherein the calculation model comprises a sintering mixture calculation module, a pelletizing mixture calculation module and a shaft furnace mixture calculation module; 2, setting a constraint condition, and setting constraint conditions of all raw materials according to the performance difference of sinteringpowder, pelletizing fine powder and lump ore; 3, calculating the cost of iron per ton: calculating the cost of the iron per ton through combining with the price and performance conditions of the resources in the iron ore market, carrying out the continuous iteration calculation through a planning solving equation, and solving the raw material ratio when the cost is minimum. Through combining withthe conditions of resources in the iron ore market and the effective chemical components, the method takes the cost of molten iron as an optimization target, performs the continuous iteration calculation through the planning solving equation, solves the optimal raw material ratio, and achieves the purpose of optimizing the ore blending.

Description

technical field [0001] The invention belongs to the field of optimized ore blending before ironmaking, and more specifically relates to an optimized ore blending method based on sintering-pelletizing-ironmaking linkage. Background technique [0002] The skyrocketing price of iron ore and the decline in quality have brought enormous pressure to the iron and steel industry. Therefore, the realization of low-cost ironmaking is an important determinant of the survival and development of iron and steel enterprises in the future. One of the foundations of economic benefits. In blast furnace production, the basic charge includes natural lump ore, sinter and pellets. The performance and usage of various iron-containing charge have an important impact on the quality and cost of molten iron. When there are a variety of iron-containing charge materials to choose from, how to use them together can find a suitable balance between the optimal performance and the lowest cost, and maintain ...
