MANUFACTURING FACILITY OF MOLTEN METAL IRON

摘要

PROBLEM TO BE SOLVED: To inhibit the wear of a refractory material, improve the energy efficiency, and prevent the short pass of electric current in an electrode in a submerged arc furnace.SOLUTION: A manufacturing facility 1 for molten metal iron reduces and fuses, in a submerged arc furnace 20, reduction iron 3 manufactured from iron oxide and carbon system reduction material to manufacture molten metal iron. A cylindrical partition wall 24 is installed inside a furnace wall 21a of a submerged arc furnace 20.
