Abstract
The trial of serpentine directly addition into ferrous materials of #5 blast furnace had been carried out within 10 days beginning on 22 Sep., 2010. The total consumption of serpentine was about 1400 t. About 1000kg serpentine was added in each charging. MgO and CaO content in serpentine were 38% and 32% respectively. The purposes of the trial were: (1) Modifying MgO content in slag to 9~10.5% so as to buffer the negative effects of higher Al2O3 content in slag. (2) Reducing MgO content in sinter from 2.8% to 2.0% so as to get relative improved tumbler strength of sinter. Overall, the performance of blast furnace had been obviously improved and the stable and consistent furnace operation had also been realized in the period of conducting the trial.
