Complex Mathematical Model of the Distribution of Multicomponent Charge in a Blast Furnace

We present the results of development of a complex mathematical model of formation of multicomponent batches of charge materials, their charging into the hopper of a bell-less top system, discharging from the hopper, and distribution over the backfill surface and show the possibilities of its technological application. The results of mathematical modeling can be used to improve the applied modes of charging and correct these modes in the case of addition of new components into the charge, they allow us to analyze the influence of the applied program of distribution of charge materials on the distribution of individual components (both in the iron ore and fuel parts of the charge), which makes it possible to select and adjust the program according to the results of predictive calculations prior to entering it into the charging control system. It is shown that the application of the mathematical model gives a possibility of making substantiated choice of rational parameters of the modes of charging of multicomponent charge and decreases the level of hazard of making inefficient decisions.
