N2 - Maintaining efficient and stable blast furnace operations at high levels of fuel injection requires .a clear understanding. of the process phenomena occurring in the furnace, especially within and below the cohesive zone. The, design of operations such as raw materials selection and specification, control of cohesive zone shape and,position, and injectant type and levels,is dependent on utilising this information. In this paper, the results of mathematical and physical modelling of all four phases in the blast furnace lower zone (solids, gas, liquid and powder) will be discussed in relation to the design of 'operational practices and the control of interactions between these phases at 'high temperatures. In particular, solids flow in the furnace, heat transfer and liquids flow within the cohesive zone, and liquids flow and powder entrapment Ilelow the cohesive- zone will bediscussed.
