Abstract：Excessive pig iron is usually charged in converter in order to increase steel output at middle and small steel plants.But some problems are occurred,such as low bath temperature, difficulty in lime melting,slag overflow at vessel mouth, increase of metal consumption, difficulty in dephosphorization and low hitting rate at the final. In order to keep the normal bath temperature and slag forming condition, the charge of pig iron should not be exceeded 10% on middle and small converter.
