Demand for high quality steel and reduction of costs have induced new targets for hot metal quality in blast furnaces: reduction of silicon and phosphorus content in hot metal. The evolution of quality in major european blast furnaces is presented in terms of silicon, phosphorus, residuals. These quality improvements have at the same time induced reduction in fuel rate. Performance of BFs in terms of hot metal quality can be improved by different ways: - better understanding of BF metallurgy. This field is described in terms of physical chemistry and experimental approaches. European experience is mostly based on probing in operating blast furnaces. As an exemple, results obtained in experimental BF in Liege are described; - better blast furnace control. European experience in this conditions), burden quality, thermal state control. The future prospects of hot metal quality are analysed. Frst step is to improve stability of burden quality, then to have a better control of burden distribution. New techniques are tested to further reduce silicon, especially as a first step for dephosphorization: - iron oxide injection at the tuyere; - desiliconization outside BF: in the runner, in a reactor.
