DRYING METHOD OF PART OF DISCHARGING PORT FOR MOLTEN MONOLITHIC REFRACTORIES LINED IN MELTING FURNACE, AND MOLTEN MATTER DISCHARGING PORT DRYING DEVICE EMPLOYED THEREFOR

Japanese Patent JP3732730

B2

PROBLEM TO BE SOLVED: To provide a drying method of a part of discharging port for molten monolithic refractories lined in a melting furnace, which is not only capable of drying sufficiently monolithic refractories on a part of molten matter discharging port, and as a result, capable of prolonging the life time of the refractories but also capable of contriving the reduction of the period of repairing rest, and a molten matter discharging port drying device employed for the drying.
SOLUTION: The molten matter discharging port drying device 10 for drying monolithic refractories on the circumference of the molten matter discharging port 15, formed at the lower part of a melting furnace body 11 is provided with an outer cylindrical tube 17, fitted into the molten matter discharging port 15 with a clearance and having a plurality of hot air blow-out ports 16 on the periphery of the same, and a hot air generating means 19 for blowing out the hot air 18, whose temperature is controlled, from among a plurality of hot air blow-out ports 16 on the outer cylindrical tube 17.
