"The production of iron in blast furnaces involves a number of entirely different processes, such as: chemical, mechanical, and physical. The input raw materials often contain many negative elements, such as heavy metals. The typical elements of this category can include lead and zinc. These elements usually enter the blast furnace in the form of oxides and sulphides. Due to the physical and chemical properties of these metals, there is a cycle between the lower parts of blast furnace with high temperatures, leading to reduction and evaporation, and the upper parts of furnace stack with low temperatures, where the vapours condense. Heavy metals can significantly influence the blast furnace process, as well as its costs. Among other things, they can fundamentally affect the life time of the blast furnace lining, which is disrupted by the formation of deposits containing some of the heavy metals. Given these facts, it is important to monitor the content of heavy metals in the input raw materials, but also throughout the entire blast furnace process. The article deals with the analysis of the impact of heavy metals within the scope of the blast furnace process." . "Tanger s.r.o." . . "Heavy Metals and Their Impact in Production of Iron"@en .
