Abstract
A tundish and associated assembly are employed for the continuous casting of molten steel containing lead. Undissolved lead can accumulate at the bottom of the tundish, work its way through the refractory material lining the tundish interior bottom and weep through the metal tundish shell bottom into a casting mold located below the tundish, which is undesirable. Expedients are provided to minimize such lead weeping.
