Abstract

The metallurgical industry is one of the main polluter of greenhouse gases like carbon dioxide (CO2). The target of the iron and steel industry is to reduce these emissions during the production process. The dominating technology for the production of hot metal as the pre-product for steel is the blast furnace route. Integral steps of it are sintering of fine iron ore and coking of coal which have both negative impacts on the environment. In the last decades several new process concepts have been developed as an environmental friendly and more sustainable alternative to the blast furnace. The FINEX®-process is the most advanced technology for hot metal production meeting the required qualities for steel production. The process uses untreated coal instead of coke and untreated fine ores, consequently the process emissions can be reduced significantly. FINEX® is a new technology which is subjected to a continuous process improvement. Especially fuel consumption and CO2 emissions should be reduced considerably. A mass and energy balance model for the FINEX®-process was developed as a tool for the investigations of process modifications on the energy consumption of fuels and electric energy. Due to the use of the balance model also cost- and time intensive experimental campaigns on the plant can be reduced.
