Abstract

The invention belongs to the technical field of metal purification, and relates to a furnace pipe device and a method for preparing ultra-high purity aluminum. The furnace pipe device is characterized by sequentially comprising a furnace pipe outer frame, a thin-wall seal sleeve and a graphite crucible from outside to inside, wherein a hinge furnace lid is arranged at the upper part of the furnace pipe; a water inlet hole, a water outlet hole, an observation hole, an air exhaust hole, an air inlet hole, an exhaust vent, a temperature measuring hole and a pressure measuring hole are formed in the furnace lid; a rubber seal strip is arranged between the furnace lid and the furnace pipe outer frame; and the furnace lid is connected and fastened with the furnace pipe through buckles and bolts. The furnace pipe device disclosed by the invention is capable of melting aluminum one time; the crystal is 65Kg; the height of a crystal aluminum ingot can reach 90cm; the single production can be increased by 2.5 times in comparison with that of a conventional high-purity aluminum production technology; an argon protection environment is only kept in the furnace pipe; the furnace pipe device has no environmental requirements on heating and electromagnetic stirring devices, and is strong in continuous working ability; compared with a conventional production technology, the furnace pipe device and the method have the advantages that the power consumption is reduced by 2 / 3; and the energy consumption cost is saved by 3 / 5.

Description

technical field

[0001] The invention belongs to the technical field of metal purification, and relates to a furnace device and method for preparing ultra-high-purity aluminum by directional solidification protected by argon. technical background

[0002] The extraction of ultra-high-purity aluminum by segregation method has been widely used in the prior art. Chinese patent document number CN101191160 records a "high-purity aluminum extraction device", which is based on the segregation theory and uses the method of pulling up In this patent, a furnace structure for extracting high-purity aluminum is mentioned. This structure is only composed of a metal shell and a graphite crucible. There is no special description on the furnace cover. Such a structure has certain shortcomings. The shell is too thin to bear the weight of the crucible and the aluminum ingot, and the crucible may burst and the aluminum liquid may leak; In a high temperature state, heat is difficult to dissipat...
