    摘要： An inspection apparatus for water flow testing of cooling passageways in gas turbine buckets provides observable visual determination of whether any blockages were formed during the manufacturing or refurbishing processes. The inspection apparatus includes a manifold block and manifold control valve mounted on a platform and adapted to engage the root end of a turbine bucket and supply fluid therethrough. The turbine bucket is affixed to the platform with a holder. The fluid exiting at the tip of the turbine bucket is visible and any blockages in the passageways will be easily discerned by the absence or paucity of fluid flow at the tip. Fluid is supplied to the manifold block by a pressure regulated fluid supply line with a control valve and a flow meter. An air supply line is also connected to the manifold block to supply air through the passageways to remove residual fluid from the bucket.

    摘要： A melt guide is provided for enclosing a bottom of an electroslag refining crucible containing a melt of electroslag refined metal. The guide includes an upper plate sized to engage the crucible bottom for attachment thereto, and includes an upper orifice drain therethrough for draining by gravity the melt from the crucible. A lower plate is spaced below the upper plate to define a plenum therebetween, and includes a lower orifice drain therethrough. A downspout extends through the plenum in flow communication between the upper and lower drains, and includes a middle orifice drain. A heater surrounds the downspout for heating the melt drainable therethrough. And, a coolant is circulated through the plenum for cooling the guide.

    摘要： Systems and methods of electroslag refining of metal include the introduction of unrefined metal into an electroslag refining process in which the unrefined metal is first melted at the upper surface of the refining slag. The molten metal is refined as it passes through the molten slag. The refined metal is collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth for protecting the cold hearth from the leaching action of the refined molten metal. A cold finger bottom pour spout is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The cold finger bottom pour spout comprises a plurality of copper segments having gaps. The gap between the segments is established and maintained by insulation structure and sealing structure positioned in each gap.

    摘要： A casting system with auxiliary cooling onto a liquidus portion of the casting can produce a metal casting that comprises a fine-grain, homogeneous microstructure. The microstructure is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state. The casting system with auxiliary cooling onto a liquidus portion of the casting can comprises an electroslag refining system as a source of liquid metal; a nucleated casting system; and at least one cooling system that supplies coolant onto a liquidus portion of the casting. The liquidus portion of the casting is cooled in a manner sufficient to provide a casting microstructure that comprises a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification from a liquidus state to a solid state.

    摘要： A bottom pour electroslag refining system refines raw material into refined liquid metal. The bottom pour electroslag refining system comprises an electroslag refining crucible; a slag; a bottom pour structure that comprises an orifice from which refined liquid metal from the electroslag refining crucible can flow as a stream of refined liquid metal; and a current path. The current path is defined in the bottom pour electroslag refining system for applying current to the raw material for melting and refining the raw material. The melted and refined raw material forms a refined liquid metal pool in the electroslag refining crucible. The current that is applied by the current path is sufficient to provide the refined liquid metal in the refined liquid metal pool with a viscosity under which the refined liquid metal can flow through the orifice under its own viscosity.
