Abstract

Development of blast furnace burden materials is an important area for optimising the economy of the blast furnace process as the raw material costs are the major cost in the production of steel. Identifying critical factors for this optimisation require close co-operation between the blast furnace engineers and the raw material suppliers. Improvements in laboratory test values of completely new pellets compared to values of existing products are not sufficient to develop blast furnace materials. At LKAB investment in the experimental blast furnace has proven to be a key tool in the development of pellets prior to full-scale testing and is providing valuable knowledge. Close co-operation with customers provides the necessary direction for burden development and deepens LKAB's knowledge of the critical factors to be considered.
