Description

Technical Field

[0001] The utility model relates to the technical field of crystallizer copper sleeves, and more specifically to a horizontal continuous casting crystallizer copper sleeve. Background Art

[0002] Cobalt-based alloy casting rod welding wires can be produced by horizontal continuous casting process. In the equipment of horizontal continuous casting process, a crystallizer is needed, and the crystallizer copper sleeve is an important part of the crystallizer. The crystallizer copper sleeve is a tubular mold with external forced water cooling. The function of the crystallizer copper sleeve is to forcibly cool and solidify the molten cobalt-based alloy introduced into the crystallizer from the melting furnace, and finally form a casting rod welding wire.

[0003] As shown in the prior art with the publication number CN201179554Y, although the diameter of the first inner hole is set to be smaller than that of the second inner hole in the prior art to realize the processing and production of materials. However, the first inner hole and the second inner hole in the prior art with the publication number CN201179554Y are always in contact with the materials, resulting in the crystallizer sleeve being eroded by the materials and wearing or being damaged. Eventually, the whole equipment needs to be replaced, which will increase the use cost and maintenance cost.

[0004] In addition, due to the small solidification shrinkage coefficient of some grades of cobalt-based alloys, the volume shrinkage of the cobalt-based alloy after solidifying into a casting rod welding wire in the crystallizer copper sleeve is small, and the friction force between the casting rod welding wire and the crystallizer copper sleeve is large during demoulding, making demoulding difficult, which seriously affects the production efficiency. Content of the Utility Model

[0005] In order to overcome the above defects of the prior art, the utility model provides a horizontal continuous casting crystallizer copper sleeve, which shields and protects the inside of the crystallizer copper sleeve body through an inner tube and an outer tube, avoiding wear or damage caused by material erosion. At the same time, the fastening bolts can also be rotated to disassemble and replace the outer tube and the inner tube, achieving the effect of reducing the use cost and maintenance cost, so as to solve the problems appearing in the above background art.

Through the connection of the outer hole and the inner hole, the circulation of the cobalt-based alloy casting rod welding wire can be ensured.

[0010] In a preferred embodiment, the diameter of the outer hole is larger than that of the inner hole. By setting the diameter of the outer hole to be larger than that of the inner hole, the contact area between the cobalt-based alloy casting rod welding wire and the inner wall of the copper sleeve body of the mold can be reduced, and the surface friction force can be reduced, which is beneficial to the demolding of the cobalt-based alloy casting rod welding wire after solidification in the copper sleeve body of the mold, and improves the production efficiency of the cobalt-based alloy casting rod welding wire.

[0011] In a preferred embodiment, a ring groove communicating with the outer hole is provided at the front end of the copper sleeve body of the mold, and an installation ring is arranged inside the ring groove. The installation ring is sleeved outside the front end of the outer tube. Through the setting of the ring groove, the installation of the installation ring can be facilitated, and the installation ring and the copper sleeve body of the mold can be in a plane, avoiding the protrusion of the installation ring.

[0012] In a preferred embodiment, a plurality of installation holes are provided on the front side of the installation ring, and the plurality of installation holes are evenly spaced.

[0025] For the convenience of shielding and protecting the inside of the crystallizer copper sleeve body 1, as Figures 1-3 shown, the protection component includes an outer tube 2 and an inner tube 3 arranged inside the crystallizer copper sleeve body 1. The outer tube 2 is arranged in front of the inner tube 3, and the front end of the inner tube 3 is fixedly communicated with the rear end of the outer tube 2; the inner diameter of the outer tube 2 is larger than the inner diameter of the inner tube 3.

[0026] Specifically, the inside of the crystallizer copper sleeve body 1 is shielded by the inner pipe 3 and the outer pipe 2 to prevent wear or damage caused by material erosion. At the same time, the fastening bolts 9 can be rotated to disassemble and replace the outer pipe 2 and the inner pipe 3, achieving the effect of reducing the use cost and maintenance cost, and avoiding the overall replacement of the crystallizer copper sleeve body 1.

[0027] To reduce the contact area and friction and ensure the demoulding efficiency of the cobalt-based alloy casting rod welding wire, as Figure 2 and 5 shown, a communicating outer hole 4 and inner hole 5 are provided inside the crystallizer copper sleeve body 1, and the outer hole 4 is arranged on the front side of the inner hole 5; the outer pipe 2 is arranged inside the outer hole 4, and the inner pipe 3 is arranged inside the inner hole 5. Through the communication of the outer hole 4 and the inner hole 5, the flow of the cobalt-based alloy casting rod welding wire can be ensured. The diameter of the outer hole 4 is larger than that of the inner hole 5. By setting the diameter of the outer hole 4 to be larger than that of the inner hole 5, the contact area between the cobalt-based alloy casting rod welding wire and the inner wall of the crystallizer copper sleeve body 1 can be reduced, and the surface friction can be reduced, which is beneficial to the demoulding of the cobalt-based alloy casting rod welding wire after solidification in the crystallizer copper sleeve body 1 and improves the production efficiency of the cobalt-based alloy casting rod welding wire.

[0028] To facilitate the installation and fixation of the mounting ring 7, as Figures 1-5 shown, a ring groove 6 communicating with the outer hole 4 is provided at the front end of the crystallizer copper sleeve body 1, and a mounting ring 7 is arranged inside the ring groove 6. The mounting ring 7 is sleeved outside the front end of the outer pipe 2. Through the setting of the ring groove 6, the installation of the mounting ring 7 can be facilitated, and the mounting ring 7 and the crystallizer copper sleeve body 1 can be in a plane to avoid the protrusion of the mounting ring 7.

Through the setting of the plurality of mounting holes 8, it is convenient for the staff to operate the fastening bolts 9 to fix the mounting ring 7 in multiple directions, so as to ensure the stability of the mounting ring 7 and avoid the situation of falling off and separating. A fastening bolt 9 is arranged inside the mounting hole 8. The rear end of the fastening bolt 9 penetrates through the mounting ring 7 and extends into the crystallizer copper sleeve body 1. The fastening bolt 9 is threadedly connected with the crystallizer copper sleeve body 1. Through the threaded connection between the fastening bolt 9 and the crystallizer copper sleeve body 1, the staff can rotate the fastening bolt 9 to disassemble the mounting ring 7, thereby improving the convenience of the staff to maintain and replace the protective components and achieving the purpose of reducing the use cost and maintenance cost.

[0030] By installing the inner tube 3 and the outer tube 2 inside the copper sleeve body 1 of the mold, the inner tube 3 and the outer tube 2 can shield and protect the inside of the copper sleeve body 1 of the mold, avoiding wear or damage to the copper sleeve body 1 of the mold caused by material erosion. Moreover, by setting the inner diameter of the outer tube 2 to be larger than the inner diameter of the outer tube 2, the contact area between the cobalt-based alloy casting rod welding wire and the outer tube 2 can be reduced, and the surface friction can be reduced, which is conducive to the demolding of the cobalt-based alloy casting rod welding wire after solidification in the copper sleeve body 1 of the mold, and improves the production efficiency of the cobalt-based alloy casting rod welding wire;

[0031] Also, since the outer tube 2 is connected to the copper sleeve body 1 of the mold through the fastening bolts 9 on the mounting ring 7, the staff can rotate the fastening bolts 9 to disassemble the mounting ring 7, thereby facilitating the staff to disassemble and replace the outer tube 2 and the inner tube 3.

[0032] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
