Phosphorus and its influence in the blast furnace process

Original language description

The course of the blast furnace process can be significantly affected by many harmful substances. Some elements may affect the technological parameters of the blast furnace process, others may fundamentally disrupt steelmaking processes following the production of crude iron. Alkaline carbonates also have a negative impact on the quality of blast furnace coke. Zinc and lead contribute to the degradation of the blast furnace lining and thus reduce its service life. For all harmful substances, it is necessary to continuously monitor and reduce their content in feedstocks as well as in crude iron. The elements that reduce the value of the produced metal include phosphorus. This element mainly affects the mechanical properties of the steel produced. The presence of phosphorus at higher concentrations is therefore harmful, except for selected machine steels. For these steels, phosphorus may be added as an alloying element. However, in most steel produced, its content is reduced in secondary metallurgy processes. Within the framework of the research, the content of phosphorus in the input raw materials and the output products of the blast furnace process was monitored. On the basis of the measurements made, the continuous cycle of this element in the blast furnace process and its influence on the technical indicators of production was analysed. The article aims to evaluate the conclusions of the research conducted to identify phosphorus reduction potential during the blast furnace process. (C) 2018 TANGER Ltd., Ostrava.
