"The global economic crisis has significantly affected the production of iron and steel. The dramatic increase in prices of all input resources has meant a substantial interference with the cost parts of the production processes. Blast furnace process is one of the most demanding production processes. It poses great demands both on input raw materials, regulation on the process flow, but also on the amount of used human capacity to ensure an efficient workflow. The continuous increase in prices of raw materials forces the metallurgical companies to increase the efficiency of the process. Disrupting the blast furnace process may bring not only technological problems, but, secondarily, also substantial increase in production costs. The input raw materials for iron production can often contain a number of negative elements. These elements in the form of compounds can later disrupt the entire process of production of pig iron. Harmfulness of the individual elements must also be considered in terms of their effects in other steel production operations. Many elements do not have negative effects throughout the entire blast furnace process, but have negative impact later, during steel production. Other substances may have negative impact not only on the primary or secondary metallurgy, but they can have crucial effect on the environment. In general, we can say that the disruption of blast furnace process brought by negative elements is determined by a number of significant causes. These causes later most often lead to abrupt changes in gas-flow speed or to a disproportional decrease of the charge. They can also cause change of viscosity or excessive heating of the blast furnace hearth. The article analyzes the amount and impact of negative elements in the blast furnace process."@en . . .
