Title:
VERTICAL VACUUM SPIRAL CRYSTALLIZATION APPARATUS AND METHOD FOR CONTINUOUSLY SEPARATING BINARY EUTECTIC ALLOY
Document Type and Number:
WIPO Patent Application WO/2023/165540
Kind Code:
A1
Abstract:
A vertical vacuum spiral crystallization apparatus and method for continuously separating a binary eutectic alloy. The apparatus comprises a vertical furnace body, a feeding system, a heating system, a circulating water cooling system, a rotating system, a vacuum system, a discharging system and an observation system. The vertical furnace body accelerates the countercurrent of the melt by means of gravity, which helps to improve the purity of a crystal. A processed object of the present apparatus and method is a binary alloy containing any component at an eutectic point, the apparatus is convenient to operate, three wastes will not be generated during a processing process, the operation environment is good, and the process is safe and controllable.
