Apparatus for directionally solidified casting products and Manufacturing method of directionally solidified casting products using the same

摘要

so that the position of the solid-liquid interface to the standard position directional control with a longitudinally uniform quality without defects The manufacturing method of the present manufacturing apparatus and the solidification of the casting for producing a molded part using a one-way. The apparatus and method for detecting the shape of the interface between the solid phase and the liquid phase using the configuration of the surface detected by the detection sensor by the statistical processing in real time and calculates a reference position, the reference position is set in advance calculated in real time, as compared to the reference position and a control unit for controlling the withdrawal speed of the mold by the elevator.
