Uncontrolled parameters influence on material and energy consumption for BOF heat
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 5
Abstract
The current article aims at analyzing the impact of uncontrolled parameters (the degree of СО to СО2 post-combustion, contents of silicon and carbon in iron, heat carrier specific consumption, heat loss of BOF vessel, etc.) on charge materials consumption and energy consumption per a ton of final steel product in BOF production. The research reported has been carried out with mathematical simulation, based on BOF heat and material sheet balances. In this paper, we describe with the analysis how the principal parameters and quality characteristics of the materials, used in BOF heat, influence the changes in metallic charge consumption and energy consumption per a ton of steel. It is shown that the use of additional agents (contaminated scrap, solid iron, magnesite flux, heat carrier) with the objective to solve current production problems of BOF heat leads to a significant growth of energy consumption as much as up to 42 kg of conventional fuel per ton of steel final product. The scientific novelty of the research is in determining the influence of the uncontrolled factors of BOF heat on initial materials consumption and energy consumption per a ton of steel. The research practical relevance is expressed by the development in BOF heat theory and practice with taking into account the impact of uncontrolled parameters.
