Abstract
When it is required to treat a charge of molten metal in the casting ladle with argon gas the lancing tube (16) is inserted in the opening of the refractory teeming nozzle (15). The opening is then sealed and made gastight by the compression of a rubber sealing ring (19) in the bore. Piped argon gas under pressure is permitted to flow through the lancing tube to emerge through a series of drilled holes (17) located in the tube above the gas sealing ring and below the nozzle stopper. As the sealing prevents any reverse flow the argon gas is forced through between the stopper and nozzle block into the molten charge. The refractory stopper in the closed position, seated against the nozzle block effectively seals the opening against molten metal flow until teeming commences.
