Abstract
As a mold containing molten metal is lowered from a heating chamber, a baffle extends around the mold. Force is transmitted from the mold to an inner section of the baffle to release connectors between the inner section of the baffle and an outer section of the baffle. As the connectors are released, a side surface on the inner section of the baffle moves out of the coplanar relationship with a side surface on the outer section of the baffle. The baffle may be integrally formed as one-piece. Rather than being formed as one-piece, the baffle may include separate pieces which form the inner and outer sections of the baffle. Alternatively, the inner section of the baffle may be disposed above and supported by the outer section of the baffle. Latches may be provided to interconnect the outer section of the baffle and the furnace assembly.
