The Influence of Chemical Composition of Steel on Steel Desulphurization

Abstract: The steel desulphurization in ladle furnace depends on temperature, oxygen and sulphur content in the steel, but mainly on chemical composition and physical properties of slag. Necessary requirement for effective desulphurization is also minimum content of easily reducible oxides in the slag. There are many correlations for expression of slag desulphurization capability, where their functional dependency on each other can be found, mainly between sulphur distribution coefficient, optical basicity, basicity, su… Show more

“…The following graphs present the results in terms of the achieved level of decreased oxidation potential and the V-ratio of slag during processing of these heats. The oxidation potential of the slag decreases during heating period as a whole, and toward its end by the action of the added CaSi wire, when the last partial back-reduction of iron and manganese oxides from the slag takes place [14], as shown in Fig. 3.…”

“…The viscosity was evaluated depending on the MgO content, the melting point of the slag and the working temperature of the slag during steel processing in the temperature range 1,550 -1,600 °C (based on articles [14][15][16]). The dynamic viscosity, depending on the temperature and chemical composition of the slag, ranged from 0.018 to 0.194 Pa s. Low viscosity values of 0.018 Pa s were achieved at high slag temperatures (above 1,650 °C) and zero MgO content.…”

“…The packaging materials can be used in a lot of fields nevertheless due to their wide range of mechanical features, high corrosion resistance and, of course, their health safety enable their application first of all in the foodstuff industry. In this case, the steel purity is defined by the level of occurrence of the non-metallic inclusions in the metal volume [3][4][5]. The non-metallic inclusions are characterized by the agglomeration into bulk metals, esp.…”
