Analysis on Influencing Factor at Converter Dephosphorization

As a detrimental element in steel,phosphor must be removed during smelting and dephosphorization is one of the most important tasks in converter smelting.Low phosphorous steel smelting proposes stricter requirement on converter smelting process.On basis of theoretical analysis,the author summarizes production data,analyzes the influence of factors of temperature,slag basicity,carbon content,slag oxidizability,hot heel operation and double slag operation on converter dephosphorization effect and provides a reference for improving dephosphorization effect at TISCO converter.Actual results indicate that dephosphorization reaction is favored by maintaining low bath temperature,building high basic slag,keeping slag with certain oxidizability and adopting hot heel and double slag operation.
