Optimization design and simulation of the spiral selector in the process of single crystal preparation were studied. Based on the analysis of simulation and experiment results, the grain structure and orientation in different section height at starter block and spiral part have been discussed. The influence and mechanism of spiral selector parameters on the behavior of the crystal selection were proposed. The design standard of the spiral selector was put forward.
