Abstract

The history of the LKAB's Experimental Blast Furnace is briefly reviewed and an introduction to the ULCOS new blast furnace is presented. The feasibility of the scale-up of the ULCOS New Blast Furnace - UNBF based on previous and new trials results at EBF are concisely discussed.
The historical trial results of using the EBF to simulate the conventional industrial blast furnace processes indicated that the EBF is able to imitate the commercial blast furnaces of different size and burden structure. The trial results can be directly extrapolated to the commercial furnaces. The discussions regarding the scale-up of the UNBF showed that based on the EBF as well as the trials of the UNBF concept it is completely feasible to determine the dimensions of a full scale furnace and the process parameters for an industrial scale trial of the UNBF concept.
