| PROBLEM TO BE SOLVED: To directly form an extended part on the end of a product by immersing the end in a molten pool of an alloy and pulling the end up at speed enough to form the extended part. SOLUTION: An Ni base superalloy material is put in a water cooled copper crucible installed in an operation chamber that can be filled with argon gas and then, the chamber is filled with argon gas, the superalloy is molten in the crucible. In order to immerse, hold and pull up the product, it is arranged in a holding means. A driving means is connected to a control means, which contains a computer controller for controlling the depth of insetting the extension end of the product into the molten material, holding time and pulling-up speed. With a rotor blade lowered into the molten pool, the inserted part of the blade is remelted through an interaction with the molten metal. The rotor blade also functions as a seed crystal for orientation growth for the purpose of solidifying the extended part from the molten superalloy. Then, the rotor blade is pulled up by moving it upward at a prescribed speed. Thus, the extended part is solidified that is provided with the same polycrystal unidirectional sulidification crystal structure as the rotor blade. | ||||||

| 49 | Elimination of shrinkage cavity in cast ingots | US13333469 | 2011-12-21 | US08347949B2 | 2013-01-08 | Mark Anderson; Todd F. Bischoff; James Boorman; Wayne J. Fenton; David Sinden; John Steven Tingey; Robert Bruce Wagstaff |
| An exemplary embodiment provides a method of eliminating a shrinkage cavity in a metal ingot cast by direct chill casting. The method involves casting an upright ingot having an upper surface at an intended height. Upon completion of the casting, the lower tip of the spout is maintained below the molten metal near the center of the upper surface. The metal flow through the spout is terminated and a partial shrinkage cavity is allowed to form as metal of the ingot shrinks and contracts. Before the partial cavity exposes the lower tip of the spout, the cavity is preferably over-filled with molten metal, while avoiding spillage of molten metal, and then the flow of metal through the spout is terminated. These steps are repeated until no further contraction of the metal causes any part of the upper surface to contract below the intended ingot height. | ||||||

| 51 | Process for repairing inlet ports of an extruder die | US12567280 | 2009-09-25 | US07942190B2 | 2011-05-17 | Charles E. Bates |
| A process for repairing one or more worn inlet ports on an interior or exterior surface of an extruder die wherein each inlet port provides an opening into an extrusion channel. The worn inlet port has a funnel shape and a diameter greater than that of the extrusion channel. The worn inlet port is repaired by placing a fused silicon oxide insert into one or more extrusion channels so that an external surface of the insert engages the interior surface of the extrusion channel, thereby forming a pocket around the insert between the circumference or perimeter of the worn inlet port and the external surface of the insert. The pocket is filled with molten metal, and the insert prevents the molten metal from entering the extrusion channel. When the molten metal hardens the inserts are removed. New inlet ports are thereby formed having the same diameter as the extrusion channels. | ||||||

| 53 | Process and apparatus for producing a turbine component, turbine component and use of the apparatus | US10794459 | 2004-03-05 | US20050005444A1 | 2005-01-13 | Georg Bostanjoglo; Nigel-Philip Cox; Rolf Wilkenhoner |
| Process and apparatus for producing a turbine component, turbine component and use of the apparatus Turbine components have to withstand high thermal and mechanical loads. It therefore proves advantageous for them to be made from a material with a preferred crystal orientation. Hitherto, the turbine components with a preferred crystal orientation have been produced as a single piece, with relatively high scrap rates. The proposed concept makes it possible to produce a preferred turbine component (9, 10) in a particularly simple way by assembling a turbine component (9, 10) at least from a first base part (1) and a build-up material (8), the subregion (7) of the joining zone having a preferred crystal orientation (2), so that disadvantageous properties of a joining zone without a preferred crystal orientation (2) which have hitherto been encountered are avoided. | ||||||
| 54 | Bimetallic plate | US10308675 | 2002-12-03 | US06752198B2 | 2004-06-22 | Teunis Heijkoop; Ian Robert Dick; Bernard Bednarz; Geoffrey Martin Goss; Philip David Pedersen; Robert Sidney Brunton; William Trickett Wright |
| Bimetallic plate is produced by providing a substrate of a first metal and, with the preheated substrate positioned in a mold cavity with a major surface of the substrate facing upwardly and to fill a portion of the depth of the cavity, a second metal is cast against that surface to form a cladding component and, with the substrate, to form the bimetallic plate. Prior to the cladding being cast, the major surface is rendered substantially oxide-free and is protected against oxidation. The cladding is cast by a melt, of a composition required for it, being poured at a superheated temperature whereby, with the preheating of the substrate, an overall heat energy balance is achieved between the substrate and the cladding. The heat energy balance causes a diffusion bond to be achieved between the major surface of the substrate and the cladding, and attainment of the energy balance is facilitated by causing the melt to enter the mold cavity through a series of gates which provide communication between at least one runner and the mold cavity. The series of gates is disposed laterally with respect to flow of the melt therethrough whereby the melt forms a laterally extending melt front. Attainment of the heat energy balance is further facilitated by causing the melt front to advance away from the gates, over the substrate surface, at a rate which is substantially uniform across the lateral extent of the front. | ||||||
