Abstract:
The single software product allowing carry out the end-to-end calculations for all ranges of the repartitions in ferrous metallurgy was created: coking, agglomeration, blast furnace smelting, converter smelting, electrosmelting, rotating furnace. Technical and economic calculations allow determining the material and heat balances, chemical composition of products of any repartition, including the cost price of the finished product. The composition of an information system includes the following mathematical models.
Forecasting model of the metallurgical characteristics of coke. Calculation of the material balance of process of coking, determination of the main metallurgical properties of coke (durability M25 and M10, reaction capacity).
Model of the agglomeration of iron ore raw materials. Calculation of the heat and material balance of the process of agglomeration and pelletizing, determination of cost price of process of the agglomeration.
Model of calculation of technical and economic indexes (TEP) of blast furnace smelting. On the basis of the certified basic data, the heat and material balance of melting, the temperature curves of gas and burden, the crystallization temperatures of slag, diameter of tuyeres, and the price cost of pig iron were calculated.
Model of calculation of TEP of converter repartition. Calculation of a heat and material balance of melting, composition of slag, temperatures of steel (intermediate product).
Model of calculation of TEP of ore thermal melting. Calculation of a heat and material balance of the melting, productivity of the furnace, consumption of the electric power, metal and slag composition.
Model of calculation of TEP of the rotating furnace. Calculation of a heat and material balance of the roasting and metallization, productivity of the furnace, chemical composition of the calcine, iron ball and slag.
