MICROWAVE IRON-MAKING FURNACE

Title:

MICROWAVE IRON-MAKING FURNACE

Document Type and Number:

Japanese Patent JP2009035776

Kind Code:

A

Abstract:

To provide a microwave iron-making furnace capable of manufacturing molten pig iron in a high energy efficiency in place of a blast furnace iron-making method.

A reactor 1 has a casing 12 composed of a magnesia-based refractory, and a bottom-plate 13 composed of an MgO-graphite mixed refractory is arranged on the bottom part of the casing 12. A graphite-crucible 17 is provided at the lower part of the reactor 1, and the graphite-crucible 17 is connected to the reactor 1 with a magnesia-made cylinder 16. Raw materials such as iron ore powder, coal powder, supplied into the reactor 1 are irradiated with the microwave from a microwave oscillators 3, and are heated. The iron ore is reduced and the obtained molten iron flows into the crucible 17 through a hole 1a to be poured into a ladle 4 from the crucible 17 through the other hole 1b.
