Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a spinning liquid copper water pouring device for semi-continuous casting. Background Art

[0002] Semi-continuous casting is different from horizontal continuous casting. Horizontal continuous casting uses the static pressure of molten copper in the insulation furnace cavity to fill the crystallizer cavity for continuous casting, while semi-continuous casting mainly uses a graphite tee to discharge and fill the crystallizer cavity. During casting, in addition to considering whether the molten copper water itself contains slag or gas, whether the discharge is smooth during the casting process, whether the copper liquid is evenly distributed in the cavity, and whether there is turbulence during the discharge process will directly change the distribution of molten copper in the crystallizer cavity and affect the entire casting crystallization and gas discharge.

[0003] The tee currently used is in a T-shaped shape, the casting pipe is connected to the head of the tee, the molten copper flows into the tee from the casting pipe, and then tumbles from the outlets at both ends of the tee, while other positions in the crystallizer cavity are relatively static, resulting in inconsistent distribution of molten copper in the crystallizer cavity. In view of this, this application is specially proposed. Utility Model Content

The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A spinning liquid copper pouring device for semi-continuous casting comprises a casting tube, a tee, a threaded hole, a cavity and a through hole, wherein a threaded head is provided at one end of the casting tube, the threaded hole is arranged at the center of the tee, the threaded head on the casting tube is threadedly connected with the threaded hole, the casting tube is hollow, the cavity is arranged inside the tee, the through hole is arranged on a side of the tee facing the casting tube, the number of the through holes is four, the through holes are evenly distributed on the tee around the threaded hole, the casting tube is connected to the cavity, and the cavity is connected to the through hole.

[0006] Preferably, the diameter of the casting hollow inner hole is 20 mm.

[0007] Preferably, the tee is a graphite tee.

[0010] Preferably, the through hole is in an arc shape.

[0011] Preferably, the spacing between the through holes is 12 mm.

[0012] Compared with the prior art, the beneficial effects of the utility model include: by arranging a cavity inside the tee head and evenly arranging four arc-shaped through holes on the tee head, molten copper enters the cavity from the casting tube and flows out from the internal cavity of the tee head toward the four arc-shaped through holes, the molten copper flowing out from the through holes forms a slight spin in the crystallizer cavity, and is diverted through the four through holes, so that the impact force of the molten copper is weakened when the molten copper is discharged, thereby making the discharge process smooth. The smooth discharge process of the molten copper is beneficial to the uniform distribution of the molten copper, which can avoid the phenomenon of shrinkage holes on the edges of the ingot, greatly improve the distribution of the molten copper and the degassing effect, greatly improve the casting stability and the quality of the casting, and the service life of the crystallizer copper sleeve.

[0021] Please see attached Figure 1-4 A spinning liquid copper pouring device for semi-continuous casting comprises a casting tube 1, a tee 2, a threaded hole 3, a cavity 4 and a through hole 5. The casting tube 1 is a graphite pipe. A threaded head 6 is provided at one end of the casting tube 1. The threaded hole 3 is arranged at the center of the tee 2. The tee 2 is a graphite tee 2. The threaded head 6 on the casting tube 1 is threadedly connected with the threaded hole 3. The casting tube 1 is hollow, and the diameter of the hollow inner hole of the casting is 20 mm. The cavity 4 is arranged inside the tee 2. The through hole 5 is arranged on the side of the tee 2 facing the casting tube 1. The through hole 5 is in an arc shape. There are four through holes 5. The spacing between the through holes 5 is 12 mm. The through holes 5 are evenly distributed around the threaded hole 3 on the tee 2. The casting tube 1 is connected with the cavity 4, and the cavity 4 is connected with the through hole 5.

[0022] By adopting the above technical scheme, the molten copper enters the casting tube 1 from the nozzle of the casting tube 1, then enters the cavity 4 inside the tee head 2 through the threaded hole 3, and then flows out from the cavity 4 inside the tee head 2 toward the four arc-shaped through holes 5. The molten copper flowing out from the through holes 5 forms a slight spin in the crystallizer cavity, which improves the distribution of the molten copper in the crystallizer cavity and avoids the phenomenon of impacting the crystallizer copper sleeve during initial discharge.
