The Comparison of Ore Raw Materials for Blast Furnace Process Based on the Quantification of Selected Key Criteria

The most important problem at the blast furnace process developing is the great coke consumption decreasing at the minimization of the general energy costs. One of the most effective ways of iron-making technical progress is the iron ore materials and coke physicochemical properties improvement which allows to increase the iron productivity and decrease the specific coke rate without construction of new blast furnaces and concentrating mills. Some of the quality indicators of iron ore raw materials and coke and their influence on the main parameters of a blast furnace smelting are considered in the paper.

Operation Parameters

Blast furnace work involves the flow of enormous volumes of raw materials. Modifications of the blast furmace operation parameters can bring about savings connected with materials consumption and also a reduction of production costs. The continuous technical-economic analysis of this process enables changes in the process to be observed by means of simple indexes. In this article, a technical-economic analysis of the blast furnace process is presented. It is based on the results of a Polish blast furnace with an overall capacity of 3200m3.

Furnace Process

Abstract The basic economic goal of pig iron process is to produce a finished product at the highest possible quality and at the lowest possible cost. The quality of pig iron depends on the quality of raw materials used in the process, quality of fuels and process parameters. The cost of fuel is one of the basic component of cost of pig iron production. Therefore, consumption of fuels should be minimized while maintaining its high quality. The main technological fuel of this process is blast furnace coke. Very often, cheaper alternative kinds of fuels are used in the form of finer sorts of coke or alternative fuels (e.g. coal dust). However, they can be used only in a limited amount. The aim of the paper is the assessment of the selected quality parameters of stabilized coke used in the blast furnace process and the comparison of their values with requirements.

The analysis of various options for the use of alumina production wastes (red mud) and oiled scale using various methods of agglomeration to produce conditioned commercial iron is presented. Co-processing utilization of red mud and oiled scale allows to obtain raw materials with an iron content of more than 50%, which meets the modern requirements for charge materials for use in the blast furnace process. The calculation analysis carried out using a mathematical model of blast furnace process, allowed to determine the optimal proportion of the iron-containing material for the partial replacement of charge materials without reducing the technical and economic indicators of blast furnace smelting.
