Title:
MOLTEN METAL TAPPING PART IN MOLTEN METAL HOLDING FURNACE
Document Type and Number:
Japanese Patent JPH06328230
Kind Code:
A
Abstract:

PURPOSE: To avoid the breakage of a nozzle caused by the shock of a stopper rod and to surely execute the stop of molten metal tapping by arranging a lifting device vertically driving the stopper rod and also, arranging relaxing mechanism for relaxing the transmission of driving force to transmission mechanism for transmitting the driving force for the lifting device to the stopper rod.

CONSTITUTION: In a molten metal tapping part 4 in a molten metal holding furnace, at the time of stopping the stopper rod 7 at the abutting position, inertia, of which the stopper rod 7 during slidingly shifting downward holds, is made to be absorbed by the relaxing mechanism E. Further, even when the adjustment of the position in the vertical direction of the stopper rod 7 is not executed so accuracy, by existence of the relaxing mechanism E, the tip part of the stopper rod 7 is made to be stopped in the flexible condition of the vertical direction corresponding to abutting on the nozzle 6 and further, the tip part of the nozzle is made to be effectively abutted on the nozzle 6 to surely execute the stop of the molten metal tapping.
