Synopsis : Cardan type bell-less top with double hoppers located vertically on the furnace axis was applied to ferromanganese smelting furnace(SF) for the sake of good burden-distribution controllability and its durability against high top gas temperature. The burden distribution characteristics were examined with a small scale model apparatus before the start of operation to understand the new system. In the model tests, a similarity condition was firstly investigated, and then ten proper tilting angles of the distributing chute for SF operation were determined within the range of 8 to 26( and the burden distribution characteristics of the apparatus were clarified as that the burden movement in the layer surface toward the furnace center was small and the size segregation scarcely occurred at the time of changing. The results were also confirmed in the test at the furnace filling. The application of results of the model experiment and filling test contributed to stable SF operation. |
