ABSTRACT METAL POURING APPARATUS AND METHOD A metal pouring ladle furnished with a sliding gate valve has a bottom pour opening fitted with a well block and a nozzle seated in the lower portion thereof, the well block and nozzle forming a flow passage leading to the valve. For introducing gas to the melt, a pipe is cast in the well block, the pipe opening to the bore of the well block above the nozzle or into an annular space encircling the top end of the nozzle component. This permits gassing before teeming commences without recourse to the flow passage through the nozzle, and so gassing is possible without distrubing any particulate silicious filler which may have been placed in the nozzle passage.
