Abstract
In the production of reduced iron by agglomerating a mixed powder of an iron material and a reducing agent to form compacts like briquettes or pellets, and reducing the compacts in a high temperature atmosphere, when the temperature of reduced compacts is 900° C. or higher, the oxide content in the reduced compacts is set at 11% or more, and the basicity of the reduced compacts is set at 0.5 or higher.
Claims3
A method for producing reduced iron by agglomerating a mixed powder of an iron material and a reducing agent to form compacts like briquettes or pellets, and reducing the compacts in a high temperature atmosphere, which method suppresses mutual sticking of the reduced compacts, wherein:
- a temperature of reduced compacts is 900° C. or higher, the basicity of the reduced compacts is 0.5 or more, and an oxide content in the reduced compacts is 11% or more, whereby any tendency of the reduced compacts to stick to each other to form lumps is significantly reduced.
