The development and use of high temperature models for the simulation of the Bosh in the blast furnace : Part I

• This report describes the development and use of a high temperature model for the simulation of the bosh in the blast furnace. As an illustration of the application of the model there follows a discussion on the influence of coke rate and coke size on the softening and permeability of a burden of pellets in the bosh, based on trials made with the model. The results indicate that the coke rate can have a critical influence on the pressure drop through the burden. With coke rates of 300 kg/ton hot metal (and less) an unacceptable pressure drop occurs. In addition the pressure drop, at a given temperature for a given coke rate, increases as the size of the coke decreases.
