Claims

[Scope of Claim for Utility Model Registration] (1) A sliding gate that is immersed in molten steel or connected to a long nozzle to prevent oxidation to control the flow rate of molten steel, and a pouring nozzle for controlling the flow rate of molten steel for rotary refractories. The outer circumferential surface of the lower end of the pouring nozzle is made conical and joined to the conical surface formed on the inner circumferential side of the long nozzle, and the inside of the conical shape of the lower end of the pouring nozzle is made to have a wall thickness of 10 mm or more. A molten steel pouring nozzle for controlling the flow rate of molten steel. (2) The pouring nozzle for controlling the flow rate of molten steel as set forth in claim 1 of the utility model registration claim, in which the lower end of the pouring nozzle, which is 10 mm or more, is formed into a curved shape such as an arcuate cross section that touches both the inner and outer circumferential surfaces. .
