Abstract: A degresser snorkel for circulating molten metal from a ladle to a vacuum vessel to thereby degas the molten metal. The degasser snorkel includes an outer castable layer lined over the outer surface of a stainless steel snorkel can. An inner refractory lining is secured to the inner surface of the snorkel can by pressure grout. A plurality of grout keys in the form of annular bands are secured to the inner surface of the steel can and cooperate with the grout in supporting the inner refractory lining. The refractory lining is formed of a plurality of interlocking refractory bricks, each of which has an hour glass-like shape. A plurality of annular rows of the interlocking bricks are built-up to thus form the inner refractory lining.
