Abstract

A mathematical model for burden distribution in the blast furnace, has been developed. A set of operational variables related with the charging system (Paul Wurth) plus other parameters related with the burden itself, such as ore and coke repose angles, weights discharged and the effect of the uprising gas, have been taken into account. These data are processed by modern computer tools. As a result, the burden distribution inside the blast furnace is obtained. Every time that a charge is added to the blast furnace, the model updates the burden distribution. The approach employed is based on considering each burden layer described by a set of interrelated polynomials. It has been tested comparing its results with burden layers obtained in a physical model of the blast furnace (scale 1/10). After installation in Aceralia blast furnace B control computers, the model is currently being employed as a tool for process control.
