Description

Technical Field

[0001] The utility model relates to the field of metal tantalum processing, in particular to an electron beam melting and forming furnace for metal tantalum. Background Art

[0002] Tantalum is mainly found in tantalite and coexists with niobium. It has moderate hardness and is ductile. It can be drawn into thin foils in the form of filaments. Its thermal expansion coefficient is very small. Tantalum has very excellent chemical properties and is extremely corrosion-resistant. It does not react with hydrochloric acid, concentrated nitric acid, or aqua regia, whether in cold or hot conditions. It can be used to manufacture evaporation vessels, electrodes for electron tubes, rectifiers, and electrolytic capacitors. It is used medically to make thin sheets or thin wires to repair damaged tissues. Although tantalum has strong corrosion resistance, its corrosion resistance is due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on its surface.

[0003] At present, electron beam melting furnaces are used for auxiliary operations during tantalum processing. The transverse gun of the electron beam melting furnace and the upper mouth of the crystallizer are almost in the same plane. According to the type of electron gun used, it can be divided into three categories: annular gun, transverse gun and axial gun electron beam melting furnaces. According to its purpose, it can be divided into four categories: melting furnace, regional refining furnace, electron beam shell furnace and multi-purpose electron beam melting furnace. It is also called electron bombardment melting. In a high vacuum chamber, the electron beam emitted by the electron gun is used to bombard the charge to be melted (consumable electrode or bulk material), so that the electron kinetic energy is converted into heat energy to melt the charge. The vacuum degree is required to reach 1.33×10-2—1.33×10-4Pa.

[0004] The patent application with publication number CN216308589U proposed in the prior art has the following advantages compared with the prior art: the utility model has the following advantages: the utility model is an electron beam melting furnace for metal assembly, which is provided with an electric push rod, a hinge and an observation window. The observation window is connected to the outer surface of the furnace body through an ammonium chain. During use, the user opens the observation window by using the hinge, places the metal button to be melted inside the forming tank, and then closes the observation window. The electric push rod is controlled by the operation panel to operate, and the forming tank and the furnace body are raised and lowered, thereby making it easier for the electron gun to penetrate the inside of the forming tank. The metal button is heated, and the user can also observe the metal inside the furnace body through the observation window. An insulation layer is provided on the inner wall of the forming groove. During the smelting process, the melting speed of the metal button is improved, which is convenient for the user to use. At the same time, an adjusting groove, an adjusting rod and a baffle are provided. The user places the processed material inside the discharge groove. During use, the user can rotate the adjusting rod to drive the baffle to rotate, open the adjusting groove, and discharge the processed material inside the discharge groove. Rotate it again to close the adjusting groove, so that the discharge groove stops feeding, so that the user can adjust the feeding of the discharge groove.

[0005] However, when processing tantalum metal, current processing equipment places the tantalum metal inside a forming tank and heats and melts it with an electron gun. However, the forming tank on the current device is a fixed setting, and it is difficult to take out the molten liquid or the formed tantalum metal after it melts.

[0006] Therefore, it is necessary to provide a tantalum metal electron beam melting furnace to solve the above technical problems. Utility Model Content
