Use of Contemporary Information Technology for Analyzing the Blast Furnace Process

Structure of the Optimal Management System for Raw Materials, Fuel and Energy Resources in Blast-furnace Production

“…The parameters of blast furnace melting are evaluated with the help of balance model of blast-furnace process developed within the natural simulation approach that may be conventionally divided into two parts, that is, model of base state and prediction model [8][9][10][11]. The model of base (reference) state enables the evaluation of the state of every blast furnace and influence of input parameters on the thermal, gas-dynamic and slag modes of blast furnace melting with the use of all actually available information on parameters of burden material, fuelenriched blast, blast-furnace gas and melting products.…”

“…The model of base (reference) state enables the evaluation of the state of every blast furnace and influence of input parameters on the thermal, gas-dynamic and slag modes of blast furnace melting with the use of all actually available information on parameters of burden material, fuelenriched blast, blast-furnace gas and melting products. The prediction model with reference to the results obtained with the help of base (reference) state model provides an opportunity to evaluate the indices of blast furnace melting when the RestricƟon of the blast-furnace shop mainly to intake (consumpƟon) of the iron ore raw materials (steel pellet, agglomerate, ore addiƟves), fluxing materials and coke; to consumpƟon of natural gas and industrial oxygen, composiƟon of smelt iron; to operaƟonal target shop' subsystem are used for this purpose [9][10][11]. The total number of technical report indices comprises more than 300 units.…”

“…The total number of technical report indices comprises more than 300 units. 'Blast-furnace shop technologist WKS' program unit is used to calculate the set of parameters characterizing the thermal, gas-dynamic, slag and blasting modes of every blast furnace within the shop during the base period (for about 30 parameters for every blast furnace) [9,11]. with the use of blast-furnace process model [10].…”

“…At the same time, the methods evaluating the blast-furnace process linearity that were developed earlier on and represented in the works [9,11] are also used.…”

Environmental and Technological Aspects of Converter Slag Utilization in Sintering and Blast-Furnace Production

“…without adjusting the sinter composition and other operating conditions of the blast furnace, we made comparative calculations in accordance with the methodology described in papers [10][11][12]. The operating parameters of Blast Furnace…”
