Development and application of optimized ore blending platform for blast furnace ironmaking system in Baotou Steel

In order to realize the integration and collaborative analysis of blast furnace ironmaking system from iron ore procurement and blast furnace ore blending optimization, this paper develops a blast furnace ironmaking whole system and whole process optimization ore blending platform for the front ironmaking system. The whole process refers to the whole process from iron ore procurement to blast furnace molten iron output. The whole system refers to the overall system of all blast furnace ironmaking in iron and steel enterprises. The optimized ore blending platform includes four parts, which are database system, single blast furnace optimized ore blending platform, whole system blast furnace optimized ore blending platform and production data acquisition and analysis platform. The platform takes iron ore as the starting point, based on the calculation of blast furnace ironmaking process and material balance, uses planning solution, linear regression, multivariate nonlinear regression, neural network and other algorithms to establish data analysis and calculation model, and forms optimal ore blending decision through statistical analysis of data. The system can realize the integrated optimization of iron ore procurement, raw ore processing, mineral processing, sintering, pellet and blast furnace process, and provides the iron ore procurement and configuration scheme that meets the requirements of blast furnace production and has the lowest cost under specific time and specific conditions. At the same time, the cost of intermediate products and molten iron raw materials in the blast furnace system can be calculated by optimizing ore distribution platform, and the deviation between production cost and planned cost also can be calculated. Managers can adjust and optimize the ore blending scheme according to the deviation of comparative data and the change of market conditions. The application of the platform in Baotou Steel realizes the intelligent, digital and accurate management of iron ore procurement and configuration. Under the premise of meeting the requirements of blast furnace production, the raw material cost of molten iron and the procurement cost of iron ore in Baotou Steel are reduced by optimizing the distribution of platform, which brings considerable economic and social benefits to the enterprise.
