POWER SUPPLY APPARATUS FOR STEEL-MAKING LADLE-REFINING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve electric characteristics of a secondary conductor from a furnace transformer of a power supply device of a steel making ladle-refining apparatus to a refining furnace electrode. ;SOLUTION: In this apparatus, all of a secondary conductor from a secondary terminal 2 of a furnace transformer 1 to an electrode gripper 7 of a refining furnace is constituted of a water-cooling type flexible conductor 5'. Further, the second conductor from a cable connector on which a cable is fitted on a furnace transformer side secondary bus-bar to an electrode gripper of the reining furnace is constituted of a water-cooling type flexible conductor. Thereby, the installation cost of the secondary conductor is reduced, and electric characteristics at a connection part on the secondary conductor are improved.;COPYRIGHT: (C)1998,JPO
