Abstract
Process for the refining of pig iron with more than 0.2% phosphorus, from the surface of the bath, using oxygen, preferably technically pure oxygen as refining medium, in which the combustión of phosphorus is totalized by delivery of mineral or film of rolling, lime and fluxes, characterized in that in the first part of the refining process, with a highly dephosphorous slag and with an intense oxygen supply, one works to carbon contents of less than 0.2%, preferably 0.1% and to a content of phosphorus which at most amounts to five times the carbon content, after which the first slag is bled, the melt is carbured at a carbon content of more than 0.2%, preferably at a carbon content of two to fifteen sometimes the carbon content obtained in the first part of the blowing, a new dephosphorization slag is placed and the refining is finished then the load with strong contribution of non-modified oxygen ada.
