Abstract

Abstract

In this paper theoretical analysis and experimental verification are combined in order to study the dephosphorization ability of the converter gasification dephosphorization slag when it is recycled and reused. Gasification dephosphorization slag had been prepared by using coke powder to reduce converter slag. The influence of different reduction temperatures on the phosphorus capacity and phosphorus distribution ratio of gasification dephosphorization slag has been theoretically analyzed. According to theoretical analysis, with the increase of reduction temperature, the phosphorus capacity and phosphorus distribution ratio of the slag after reduction both increase. In the laboratory, gasification dephosphorization slag is used to conduct hot metal dephosphorization experiments, and a single temperature variable is set to study the dephosphorization effect of gasification dephosphorization slag when it is reused. The results show that converter gasification dephosphorization slag has new dephosphorization, significant dephosphorization effect during the early stage of the reaction. With the increase of temperature, the dephosphorization capacity of gasified dephosphorization slag decreases, and the dephosphorization speed becomes slower, which is in agreement with thermodynamics law.
