Abstract

The blast furnace process is a collection of a large number of physicochemical, thermal and mechanical processes. All processes do not run in isolation, but in parallel and in a certain interaction. The input raw material includes ores, basic additives and fuel. The output products of the blast furnace process are pig iron, slag and blast furnace gas. The current highly competitive environment forces iron manufacturers to monitor in detail the quality of all input raw material and internal processes. An important aspect is the quality of ore raw materials, which fundamentally affects the technological production process, but also the quality of the metal produced. Ore materials can be assessed using a wide range of criteria - chemical, physical, mechanical, technological. In each category we can find a large number of specific parameters. The evaluation can then be carried out for tens of different ore materials. This multi-criteria character offers the possibility to use logistic tools to support decision-making. The article deals with experimental use of logistic tools of multi-criteria decision making for evaluation of ore materials. The article analyzes the results of the research, which was executed in the conditions of the company TŘINECKÉ ŽELEZÁRNY, a. s. The research was focused on possibilities of determination of complex quality of ore raw materials in relation to blast furnace process.
