Description

Technical Field

[0001] The utility model relates to the technical field of preparing high-purity titanium, in particular to a device for preparing high-purity titanium. Background Art

[0002] High-purity titanium refers to titanium material containing very few impurities, typically with a purity of over 99.9%. Due to its excellent physical and chemical properties, high-purity titanium is widely used in aerospace, medical devices, the chemical industry, and electronic products. High-purity titanium has strong corrosion resistance to a variety of acid, alkali, and salt solutions, making it suitable for harsh environments. Titanium has a density of approximately 4.5g / cm3, but its strength is very high, with good specific strength. High-purity titanium has good compatibility in the body and does not cause rejection reactions, so it is widely used in medical devices and implants. High-purity titanium can still maintain good mechanical properties at high temperatures, making it suitable for high-temperature applications. Due to its high purity, high-purity titanium performs well in various extreme environments, making it an indispensable and important material in modern industry. With the continuous advancement of technology, the production process and application range of high-purity titanium are also constantly expanding. Vacuum arc melting is a common method for preparing high-purity titanium. By evacuating the melting furnace to create a low-oxygen environment, arc heating is used to melt the titanium raw material, which is then remelted to remove impurities. The molten titanium cools to form a high-purity titanium ingot.

[0003] When using a vacuum arc melting furnace to prepare high-purity titanium, the molten high-purity titanium needs to be cooled and solidified in a mold to form a titanium ingot. Water cooling is generally used. However, after cooling, the water temperature continues to rise, and the water cannot be cooled in time, which will lead to an increase in the subsequent cooling time and affect the efficiency of preparing high-purity titanium.

Before the melting begins, the air in the furnace body 1 is evacuated to establish a low-pressure environment. This can reduce the presence of gases, especially oxygen and nitrogen, to prevent them from reacting with titanium during the melting process and causing an increase in impurities. Arc melting furnaces usually use tungsten or graphite as electrodes. When the electrodes contact the molten metal, current flows to form an arc. The temperature of the arc can exceed 3000°C. The heat generated by the arc causes the titanium raw material to melt rapidly. The molten titanium is in a high temperature and vacuum environment in the furnace, which effectively removes impurities. During the arc melting process, the molten metal can be repeatedly remelted, which helps to further improve the purity of the titanium. The remelting process can remove elements such as oxygen and nitrogen dissolved in the titanium.

[0026] The driving part includes a motor 303 fixedly connected to the outside of the water pool 6, the stirring shaft 301 is fixedly connected to the output end of the motor 303, and the motor 303 is electrically connected to an external power supply.

[0028] A guide plate 305 is rotatably mounted inside the water tank 201 via a rotating shaft 304 , and a spoiler hole 306 is formed on the guide plate 305 .

[0029] Specifically, after the water enters the water tank 201, the water flow drives the guide plate 305 to rotate under the impact of the water flow, stirs the water, and disturbs the water through the flow-disturbing holes 306, so that the water flows faster, the efficiency of heat exchange is accelerated, and the water temperature is quickly reduced, further improving the efficiency of preparing high-purity titanium.
