“…The phosphorus partition ratio increases with (mass%FeO)ϩ(mass%FeO 1.5 ) where the value is under 45 mass%, while it decreases with increasing (mass%FeO)ϩ(mass%FeO 1.5 ) in a high content region. Same tendency was observed for the data reported by Suito et al 11) and Wrampelmeyer et al 12) The maximum value of phosphorus partition ratio have obtained at (mass%FeO)ϩ(mass%FeO 1.5 ) is approximately 45 mass%. On the other hand, from the data measured by Nagabayashi et al 13) which (mass%FeO)ϩ(mass%FeO 1.5 ) is lower than 33 mass%, the maximum phosphorus partition ratio is obtained at lower FeO x content compared with others.…”

“…Figure 6 also shows that the calculated values of other researcher's results. [11][12][13][17][18][19] The activity coefficients increase with increasing basic oxygen content for every report. The results of Suito et al 11) and Selin 17) are larger than those of present study and the other researchers, because the oxygen contents in metal for both Suito et al and Selin are relatively higher than the other reported value (over 0.1 mass%O).…”

“…It clearly indicates that the calculated values agree well with the actual values, from the post-dephosphorization conditions throughout the post-decarburization conditions. Also shown in this figure are the results of the experiment on the dephosphorizing equilibrium in molten steel, conducted by Suito et al [5,6], and the results of the conversion into phosphorus distribution ratios in carbon-saturated iron from the measurement of phosphorus distribution ratios of solid, conducted by Ito and Sano [7]. The results of any of the equilibrium experiments agree well with the phosphorus distribution ratios obtained from equation (3).…”

The authors propose a new refining process, by which hot metal is dephosphorized and decarburized continuously in the same basic‐oxygen furnace, with intermediate deslagging following dephosphorization. After decarburization, slag is kept inside the furnace and reused to dephosphorize the next charge so as to minimize the quantity of slag discharge. Experiments were made to clarify the properties of this process, using an 8‐ton experimental converter. The results confirmed high productivity or a higher rate of dephosphorzation achievable with an increased rate of oxygen blowing and the addition of iron ore. Because of the dephosphorization by low‐basicity slag and the hot recycling of decarburizationslag to dephosphorize the next charge, lime consumption was relatively low. The proper conditions of this process, such as the slag composition for dephosphorization, rate of oxygen supply, bottom agitation, and rate of intermediate deslagging, are also discussed, based on the experimental results.

Equilibrium Distribution Ratio of Phosphorus between Solid Iron and Magnesiowustite-saturated Al2O3–CaO–FetO–MgO–SiO2 Slag at 1623 K

et al. 2013

In the conventional iron-making process, the oxygen potential in the hearth of the blast furnace is determined only by the temperature because of the carbon-saturated conditions. As a consequence, impurities such as phosphorus are reduced and dissolved in the iron because of the excessively low oxygen partial pressure. The oxygen partial pressure can be controlled by using gas reductants such as hydrogen and carbon monoxide. Under these conditions, solid iron is obtained because of the low carbon content. In this study, the equilibrium distribution of phosphorus between the solid iron and molten slag is investigated at 1 623 K as functions of the oxygen partial pressure and the basicity of the slag. The experimental results show that the phosphorus content in the solid iron is sufficiently low under the experimental conditions employed. The phosphate capacity is also evaluated, and a regression equation is obtained by comparing the results with those of previous studies.
