摘要： PROBLEM TO BE SOLVED: To provide a repairing method by which an oriented solidified crystal blade is repaired after heating, melting and solidifying so that the crystalline structure after the repair is the same as that of a base metal.
SOLUTION: A part to be repaired is repaired after heating, melting and solidifying the part by a heat source 3. The directional solidified crystal having the same crystalline orientation as the base metal can be grown into the melted part 2 to be repaired by controlling the heat input and/or the heating pattern during the melting so that the ratio (G/R) of the temperature gradient (G) at a boundary between the solidified part and a melted part to the solidification speed (R) at the melted part 2 to be repaired is not less than the value of allowing the directional solidified crystal to grow.

摘要： PROBLEM TO BE SOLVED: To provide a simulator for casting process and a judging method therefor capable of making an optimum casting plan based on a new evaluation index for casting defects.
SOLUTION: An analytical technique for segregation-convection based on a segregation-convection solidification model and an analytical technique for crystal growth based on nucleation-crystal-growth model are simultaneously used every time step. Concentration, speed of flow, temperature, solidus rate, solidification structure, crystal orientation, dendrite arm spacing, and nucleation site are simultaneously output. The existence of casting defects is estimated from the index of casting defects which has been calculated based on them. Not only by the aforementioned casting process simulator, but also from the calculated concentration and temperature by a casting process simulation based on an arbitrary casting plan, the freckle defect evaluation index (Rayleigh Number), in which the segregation and flow of molten metal are considered, and the defect evaluation index for foreign crystal, in which the nucleation mechanism of foreign crystal being considered, are simultaneously evaluated so as to judge the quality of the casting plan.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for unidirectional solidified casting with which even in the case of being a complicated mold shape and casting plural cast products at one time of casting, the development of a single crystal, etc. can be produced by making large of the temperature gradient in the unidirectional solidified direction and making small of the temperature gradient in the orthogonal direction to the above direction. SOLUTION: The heating of a base plate is prevented by arranging a water-cooling copper plate on the base plate. Further, when the mold is drawn out from a heating furnace, the position of the water-cooling copper plate to the heating furnace is not made to shift while the water-cooling copper plate is not interfered with the projecting part, etc., of the mold. Then, a copper column projected to the cooling plate is exposed on the base plate. Further, when the mold is drawn out from the heating furnace, a heat-radiation preventive plate and the water-cooling plate are made to the inserting state into a space part at the inside of the mold while these plates are not interfered with the projecting part, etc., of the mold. Furthermore, the water-cooling plate is divided into plural pieces and each divided plate can independently be inserted into the space part.

摘要： PROBLEM TO BE SOLVED: To provide a grain-oriented solidification casting apparatus with which cooling effect is increased in the case that molten metal poured into a mold is subjected to the grain-oriented solidification. SOLUTION: The molten metal 32 held in a cavity 21 of a mold 20, is subjected to grain-oriented solidification by drawing out the mold 20 disposed at the periphery in a prescribed range from a heating chamber 10 heating the metal for casting a cast product 31 to not lower than the melting temperature. This grain-oriented solidification casting apparatus 100 is provided with a driving rod 42 drawing out the mold 26 from the heating chamber 10, a gas nozzle 52b for rapidly cooling the mold 20 by injecting cooling gas from the inside in the prescribed range disposing the mold 20 and a gas nozzle 52a for rapidly cooling the mold 20 by injecting the cooling gas from the outside in the prescribed range disposing the mold 20. Further, a baffle 15 which does not move even if the driving rod 42 is ascended/descended, is provided and this baffle 15 shuts off radiated heat from the heating chamber 10. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To produce a casting having good dimensional precision by accurately predicting the shrinking and the deforming quantities in the casting. SOLUTION: Temp. calculations of the casting 4 and a mold 1, 2 at the time of solidifying and cooling and calculation of thermal stress and deformation based on the temp. calculations are performed with an finite element method. In this way, the shrinking and the deforming quantities of the casting are predicted and this predicted result is fed back to the design of a pattern. This analyses of the thermal stress and the deformation are executed in the consideration of the deforming resistance of the mold 1, 2 and a dynamic boundary condition between the casting and the mold interface.
