Development of Approximate Simulation Model Aiming at Fast Evaluation of Sintering Process

Abstract

An approximate simulation model of sintering process has been developed. With this model, which is self-concluded type, the calculation time is markedly shortened in comparison with that of conventional theoretical model expressed by partial differential equations. Characteristics of bed permeability, which are important at simulation with self-concluded model, has been studied by systematic sintering pot test. Based on results of the test, statistical equations have been obtained and included in the model. These equations give permeability resistance of each zone at sintering bed from raw materials and sintering conditions.
As a result of verification of the model both by sintering pot test and sintering machine operation, it has been confirmed that the model works effectively in practical use. The model can be used for evaluating and controlling sintering operation in actual process.
