Detailed Description
The following provides a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.
Fig. 1-1 is a schematic structural view of one of the tantalum lining plates of the present invention, fig. 1-2 is a right side view of fig. 1-1, and fig. 2 is a schematic structural view of one of the tantalum lining plates of the present invention after being rolled into a cylindrical shape. As shown in the above figures: the tantalum lining inner cylinder structure provided by the utility model comprises a plurality of tantalum lining plates 1, wherein the tantalum lining plates 1 are welded together from top to bottom and then bent into a cylindrical tantalum lining inner cylinder 2 from head to tail.
The height range of each tantalum lining plate 1 is 50-100mm, the upper side and the lower side of each tantalum lining plate 1 are respectively provided with a bending turned edge 3, and the thickness range of each tantalum lining plate 1 is 0.8-1.5 mm.
Fig. 3 is a schematic structural view of the outer cylinder of the present invention after being unfolded, fig. 4 is a schematic structural view of the outer cylinder of the present invention after being rolled into a cylindrical shape, the outer cylinder 4 is a cylinder rolled by using one plate, and the rolled joint is fixed by using a connecting plate 5 and a fastener 6. In a specific implementation, the connecting plate 5 and the outer cylinder 4 may be welded together. An argon inlet 9 is arranged on the annular argon channel 7, and an argon outlet 10 is arranged on the longitudinal seam argon channel 8; or an argon outlet is arranged on the ring argon channel, and an argon inlet is arranged on the longitudinal seam argon channel. An argon standby port is arranged on the ring argon channel or an argon standby port 11 is arranged on the longitudinal seam argon channel.
Fig. 5 is a schematic view showing a structure in which an inner liner cylinder structure and an outer cylinder of the present invention are combined and then unfolded, and fig. 6 is a schematic view showing a structure in which an inner liner cylinder structure and an outer cylinder of the present invention are combined and then rolled into a cylindrical shape. The tantalum lining cylinder manufacturing structure comprises: the device comprises a tantalum lining inner cylinder structure and an outer cylinder body 4 coated outside the tantalum lining inner cylinder structure during manufacturing, wherein an argon channel is arranged on the outer cylinder body 4 and comprises an annular argon channel 7 and a longitudinal seam argon channel 8, and the annular argon channel 7 is located between two adjacent tantalum lining plates 1. The tantalum lining inner barrel structure comprises a plurality of tantalum lining plates 1, the tantalum lining plates 1 are welded together in an up-down mode and then bent into a cylindrical tantalum lining inner barrel in an end-to-end mode, an argon channel passes through the welding position of the tantalum lining plates, and when the tantalum lining plates are welded, argon protection is introduced into the argon channel.
In the manufacturing process, the tantalum lining cylinder is divided into a plurality of small sections, and the two ends of each small section are folded to enhance the strength of the lining cylinder so as to prevent the tantalum lining cylinder from bulging in actual use.
When the tantalum lining cylinder with the folded edge is manufactured, the perimeter of the lining cylinder is unfolded according to the middle diameter of the lining cylinder. In the tantalum flat plate state, a flanging machine is used for firstly extruding the flanging of the lining cylinder before the rolling, and then a sleeve tool with a groove is installed on an upper roller of a plate rolling machine for rolling the tantalum lining cylinder.
The outer circumference of the tantalum lining cylinder is measured after the tantalum lining cylinder is rolled to a circle, and the outer diameter is converted into the tolerance range required by a drawing before the closure longitudinal joint of the tantalum lining cylinder can be welded.
When a plurality of small sections of tantalum liners are assembled, two half tools are adopted to assemble the small sections of tantalum liners together so as to ensure the tolerance requirements of ovality and straightness of the whole tantalum liner.
An argon channel is arranged inside the two half tantalum lining cylinder assembling tool, a rear argon inlet and outlet is arranged outside the tool and is communicated with the argon channel inside the tool, so that argon protection is carried out on the back surface of a welding seam when longitudinal seam welding of the tantalum lining cylinder and edge folding welding of small sections of tantalum lining cylinders.
Because the melting point of tantalum is as high as 2980 ℃ and the melting point of carbon steel is as high as 1450 ℃, if a defect is found in the butt-joint annular seam of the tantalum lining cylinder, the defect cannot be directly repaired, because the carbon steel of the equipment base layer is corroded in the repairing process. And the welding seam defect can be directly repaired when the tantalum lining cylinder edge folding circular seam is found to be defective, because the practice that the distance between the edge folding tantalum circular seam and the carbon steel of the equipment base layer is 4mm proves that the carbon steel of the equipment base layer can not be corroded in the repairing process.
The utility model has important application in high and new technical fields of electronics, metallurgy, steel, chemical engineering, hard alloy, atomic energy, superconducting technology, automotive electronics, aerospace, medical health, scientific research and the like.
