Abstract

A method for calculating the state inside the sintered layer is provided that takes into account heat and gas mass transfer in two directions: the thickness direction of the sintered layer and the length direction of the machine. [Solution] A numerical calculation method for an iron ore sintering process, in which powdered material containing iron ore is sintered in a sintering machine to produce sintered ore, includes the steps of: creating a calculation mesh in an area formed by the raw materials and sinter cake on the sintering machine; and calculating the state inside the sintering machine by calculating the amount of chemical reaction inside each cell, the heat of reaction, the amount of heat transfer between gas molecules and solids, the physical properties of each substance, temperature change, and the amount of heat transfer between each cell in the machine length direction and layer thickness direction, and the amount of gas molecule transfer between each cell in the machine length direction and layer thickness direction.
