The blast furnace (Fig. 1) is the main process in the world used in producing iron for primary steel production (Biswas 1981; Omori 1987). The furnace is a large refractory-lined counter-current heat exchanger and chemical reactor, where enriched and agglomerated ores, sinter or pellets, are reduced and smelted by hot gases formed by combustion of coke and hydrocarbons. Because of the extreme conditions in the furnace it is very difficult and costly to directly measure internal variables of the process. The internal state must, therefore, be estimated from information at the furnace boundaries, such as measurements of the top gas and hot metal quantities, temperature and chemical composition, blast parameters and wall temperatures.
