Production system for a hafnium crystal bar and the method thereof

Abstract

The present invention discloses a production system for a hafnium crystal bar and the method thereof. The technical program includes a power supply unit with large DC current, an iodizer, a molybdenum insulator provided inside the iodizer, a thermostatic device, a cooling unit, a vacuum unit, an iodine box for iodizing the iodizer, an electrode unit electrically connected to the power supply unit, wherein the electrode unit is disposed above the iodizer, a crystallization unit provided inside the iodizer, wherein the crystallization unit is connected to the electrode unit, and a rough hafnium provided between the iodizer and the molybdenum insulator. The thermostatic device is a structure with an insulation layer provided outside an inner tank, and an electric heating wire is provided between the inner tank and the insulation layer. The inner tank of the thermostatic device is filled with a saline solution.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Chinese Patent Application No. CN201710665149.5, filed on Aug. 7, 2017, the entire content of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates a production system for a hafnium crystal bar and the method thereof.BACKGROUND OF THE INVENTION[0003]At present, the industrial production technology of the hafnium crystal bar is monopolized and blocked by the foreign companies. The domestic production technology is immature and unstable, and stays in the laboratory stage and faces the following problems: (1) The production efficiency and the production of single furnace is low, and the production cost is high, which cannot meet the requirements of industrial production. (2) The problem of a low production rate in a later production stage cannot be solved. (3) The wire breakage phenomenon cannot be avoided. (4) The crucible pollution is high and the trace element cont...

AI Technical Summary

Benefits of technology

The present invention can increase the speed of producing high-quality hafnium crystal bars. It improves the production speed and quality of a single furnace and reduces energy consumption. Additionally, it reduces the use of accessories and supplies and lowers the content of impurities like iron, nickel, and chromium.

Problems solved by technology

The domestic production technology is immature and unstable, and stays in the laboratory stage and faces the following problems: (1) The production efficiency and the production of single furnace is low, and the production cost is high, which cannot meet the requirements of industrial production.

(2) The problem of a low production rate in a later production stage cannot be solved.

(4) The crucible pollution is high and the trace element contents cannot meet the standard.

(5) The core wire often distorts in the heat and touches the molybdenum insulator, which leads to frequent short-circuit phenomena.

(6) The discharging phenomenon caused by a high-voltage in the earlier production stage often breaks the crucible, causes accidents, and also fuses the core wire easily.

(7) The ineffective deposition of the iodine makes the effective time of production short.

The existence of the problems listed above restricts the production of the hafnium crystal bar seriously.

Therefore, the national defense industry and advanced manufacturing industry cannot be supported materially.
