The evaluation of hot metal treatment was carried out on the basis of the previous research work, the focus of which was CaO delighting additive dephosphorization. Foreword Since the inception of the L century, steel making and blast furnace ironmaking have become the major processes in the steel industry. General hot metal contains a certain concentration of silicon, sulfur, phosphorus, they depend on the quality of raw materials in the charge and blast furnace operation. Taking into account the content of these elements in hot metal and the composition of the final product steel, the best, at
