Abstract

The invention discloses a metal single crystal preparation device and process, and the device comprises a furnace body; and a seed crystal rod, a seed crystal fixed with the seed crystal rod, a thermal insulation layer, a crucible cover fixed with the thermal insulation layer, a mold fixed with the crucible cover, a crucible located in a space enclosed by the thermal insulation layer, and a crucible pillar for supporting the crucible, which are sequentially arranged in the furnace body from top to bottom. The furnace body is provided with an air inlet and an air outlet, and the outer wall of the thermal insulation layer is provided with an induction coil for heating the crucible. The crystal forming rate of the copper raw material is greatly increased, and the single crystal quality and process repeatability of the prepared material are improved; through intervention of a mold, the copper melt can be drawn according to the shape of a finished product, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of metal single crystal preparation, in particular to a metal single crystal preparation device and process. Background technique [0002] The metal copper single crystal workpiece is composed of long-range ordered copper atoms, which eliminates the grain boundaries in the material, avoids the generation of resistance generation sources and signal reduction sources, and makes copper single crystal materials have excellent electrical conductivity and ductility. . Compared with ordinary copper materials, the quality of audio and video transmission, conductive signal transmission, and ultra-long thin wire drawing has been greatly improved. It has a very wide range of applications in the fields of new energy vehicles, consumer electronics, microelectronic devices, and integrated circuit preparation. [0003] In the existing copper single crystal preparation process, such as continuous casting method, etc., it ...
