Abstract
The article presents the technological features of the charge choice for fi lling the blast furnace. The developed complex of mathematical models and software was designed for charge calculation to fi ll the blast furnace with adjustable process of slag formation and recovery. When blowing, the fi rst portions of slag-forming and iron-ore materials were located in the furnace shaft and there was no need for gradual improvement of the ore load. The basic functional capabilities of the software allowed the following: manual maintenance (the structural characteristics of blast furnaces; the parameters of the previous blowing-in, properties of slag-forming and iron ore materials, coke, and others); the calculation of the charge for fi lling and cast iron and slag properties at user-specifi ed spending of slag-forming materials and fl uxes and blast parameters; calculation of the optimal charge composition for fi lling and blowing selection subject to the restrictions in heat, slag, gas-dynamic regimes and the quality of the cast iron; diagnosis and presentation of calculation results in tabular and graphical forms, saving them in the database.
