Predictive Modeling of the Hot Metal Sulfur Content in a Blast Furnace Based on Machine Learning

Metals, 2023
The sulfur content of hot metal in a blast furnace is an important index that reflects the production effects and quality of the hot metal. Establishing an accurate prediction model for hot metal sulfur content can guide the production process.

Use of computational thermodynamics software to determine the influence of CaO, FeO and SiO2 on hot metal dephosphorization efficiency

Journal of Materials Research and Technology, 2020
The properties of the mixtures used in hot metal dephosphorization, such as solid and liquid fraction phases, CaO and FeO activity and viscosity, are determinant for the process efficiency. The influence of these properties on hot metal dephosphorization

New trends in basic oxygen furnace dephosphorization [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2020
Except for special grades of steel where it is used as an alloying element, phosphorus is regarded as an impurity that must be removed. Considering the conventional integrated iron and steelmaking, there are primarily two processes for phosphorus removal.
