A metal delivery system for a casting system includes a spout having a spout passageway extending through the spout with an elongated slot as a bottom orifice. A bottom control pin is positionable within the spout and is movable between a closed position and an open position. In certain aspects, in the closed position, the bottom control pin engages a portion of a surface of the passageway proximate to the bottom orifice.

A method of sealing a slag drain in a direct smelting vessel is disclosed. Also disclosed are a method of maintaining a slag drain channel and a direct smelting vessel with a slag drain channel that extends through a sleeve of refractory material installed in the direct smelting vessel. The method for sealing the slag drain includes locating a pre-formed refractory material at an inlet end of the slag drain channel so that it is exposed to a molten bath contained within the direct smelting vessel and sealing the slag drain channel with sealing material downstream of the pre-formed refractory material.

The invention relates to a ceramic refractory stopper (a stopper device) for controlling a flow of molten metal at an outlet opening of a metallurgical vessel, such as a tundish.

The invention concerns a stopper rod and a method to provide a uniform gas curtain around a stopper rod.

A ventilating stopper rod has a temperature measurement function and is used for continuous casting. The stopper rod has a rod body, a rod head, a temperature measurement unit, a connecting pipe and exhaust passages; the rod body is a hollow structure; the upper end of the rod body is connected with the connecting pipe; the lower end of the rod body is connected with the rod head; the temperature measurement unit is used for measuring the temperature of the molten steel; the open end of the temperature measurement unit is connected with the rod head and communicates with the inner cavity of the rod body; the closed end of the temperature measurement unit extends out from the lower end of the rod head and is exposed from the rod head.
