Method for reducing particulate iron oxide to molten iron with solid reductant |
摘要 |
A method for reducing particulate iron oxide to molten iron utilizing solid carbonaceous fuel as reductant in a shaft type reducing furnace, in which a furnace burden is formed of a mixture of iron oxide lumps or pellets and particulate solid fuel. Reacted top gas is upgraded and recirculated through the burden in counter-flow relationship thereby heating, reducing and melting the burden. The heat for reduction and melting is generated by passing electric current through the burden.
