Outline of Final Research Achievements

In order to develop “visualization technology for raw material softening behavior in high temperature process aiming for sustainable low carbon ironmaking”, 3D dimensional information and slag melt physical properties of slag particle bed layer during softening at high temperature were given to particle method numerical simulation. As a result, basic numerical model to predict for gas and liquid flow in slag particle bed layer during softening at high temperature was established.

Academic Significance and Societal Importance of the Research Achievements

原料鉱石の軟化・融着を伴う溶鉱炉プロセスでは,炉内の安定した通気性・通液性の確保が最も重要な操業因子の一つである.従来の炉内通気・通液性の推算方法では,固体原料鉱石の粒径を基準としていたため,原料軟化による形状変化や溶融に伴う融着現象を正しく反映することが困難であった.本課題で開発した原料同士の融着に伴って縮小していく通気・通液のための有効経路の直接算出技術により,溶鉱炉操業の安定化が期待できる.
