MOLTEN STEEL SUPPLY METHOD AND MOLTEN STEEL SUPPLY NOZZLE FOR CONTINUOUS CASTING USING A SHROUD NOZZLE

摘要

PURPOSE: A molten steel supply method and a molten steel supply nozzle for continuous casting are provided to uniformly control the spreadability of molten steel put into a tundish through a shroud nozzle.;CONSTITUTION: A molten steel supply nozzle for continuous casting comprises multiple diaphragm pieces(100), movable ends(400), fixed ends(500), a lower fixing plate(201), and an upper rotary plate(200). The movable and fixed ends are formed on the top and bottom surfaces of the diaphragm pieces, respectively. The lower fixing plate is coupled to the fixed ends and fixes the fixed ends. The rotary plate is coupled to the movable ends of the diaphragm pieces and opens and closes the diaphragm pieces by moving the movable ends.;COPYRIGHT KIPO 2012
