Abstract
A stopper rod which has a plug at one end fits snugly into the inside of the nozzle having multiple ejection orifices. The plug is provided with at least one slot or opening which can be located directly over a selected orifice to allow passage of molten metal therethrough. When erosion occurs, the plug is indexed to locate the opening over a different, uneroded orifice.
