Abstract
The invention relates to a stopper rod adapted to deliver gas during pouring of molten metal comprising a stopper body having an internal chamber and a gas discharge port, a bore connecting the internal chamber to the gas discharge port, the internal chamber and the bore defining a gas passageway. According to the invention, the walls of the gas passageway are provided with a layer of a material which will not produce carbon monoxide at the temperature of Use.
The stopper rod of the invention does not contaminate the gas passing therethrough.
The stopper rod of the invention does not contaminate the gas passing therethrough.
