The invention has the beneficial effects that:
the bowl bottom is matched with the sleeve to fix the tube body in the furnace head box, the shaft hole is used as a flow hole, and the copper liquid flows into the confluence groove through the shaft hole to be stored. When the amount of the copper liquid in the confluence groove reaches a certain degree, the copper liquid flows out from the copper outlet hole for pouring. The quantity of going out the copper hole can change the regulation, goes out under the more condition of copper hole quantity, the area that the copper liquid flows out is great, and the outflow speed of corresponding copper liquid also obtains very big promotion. Meanwhile, the side wall of the tube body has more space than the bottom part for opening the copper hole. Therefore, the casting speed is greatly improved.
The outer opening of the copper outlet hole is positioned below the inner opening of the copper outlet hole.
The copper outlet hole is a circular hole, and the included angle between the axis of the copper outlet hole and the horizontal plane is 0-15 degrees.
The pouring pipe for vertical casting further comprises a bottom plug clamped at the bottom of the confluence groove, and the outer wall of the bottom plug is attached to and tightly pressed on the side wall of the bottom of the confluence groove.
The outer wall of the pipe body is a cylindrical surface, and the outer diameter of the pipe body is 20-200 mm.
The number of the copper outlet holes is 4-18.
The shaft hole is a cylindrical hole, and the diameter of the shaft hole is 5-40 mm.
Other features and advantages of the present invention will be disclosed in more detail in the following detailed description of the invention and the accompanying drawings.
[ description of the drawings ]
The invention is further described below with reference to the accompanying drawings:
FIG. 1 is a schematic sectional view of a vertical casting pipe according to an embodiment of the present invention.
[ detailed description ] embodiments
The technical solutions of the embodiments of the present invention are explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.
In the following description, the appearances of the indicating orientation or positional relationship such as the terms "inner", "outer", "upper", "lower", "left", "right", etc. are only for convenience in describing the embodiments and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the present invention.
Example (b):
referring to fig. 1, the embodiment provides a casting pipe for vertical casting, which comprises a pipe body 1 and a bowl bottom 2 fixed on the outer wall of the upper end of the pipe body 1, wherein a sleeve is installed outside the bowl bottom 2 to fix the pipe body 1 in a furnace head box. The outer wall of the pipe body 1 is a cylindrical surface, and the outer diameter of the pipe body 1 is 20-200mm, so as to ensure that the size of the pipe body 1 is consistent with that of the prior art, and the pipe body 1 of the embodiment is produced by improving a production mold of the prior pipe body 1.
The pipe body 1 is vertically arranged, the middle of the pipe body 1 is provided with a shaft hole 3 extending along the vertical direction, the upper end of the shaft hole 3 is exposed out of the bowl bottom 2, the shaft hole 3 is used as a flow hole, and copper liquid flows into the pipe body 1 through the upper end of the shaft hole 3. The side wall of the shaft hole 3 is generally cylindrical, and the diameter of the shaft hole 3 is 5-40 mm. The diameter of the axial bore 3 ensures the flow of copper into the interior of the tube body 1.
The bottom of body 1 is provided with converges groove 4, and the lower extreme in shaft hole 3 communicates to converges groove 4, converges the bottom seal of groove 4. Therefore, the molten copper enters the confluence groove 4 through the shaft hole 3 and is stored and stayed to a certain extent.
Specifically, the casting pipe for vertical casting further comprises a bottom plug 5 clamped at the bottom of the confluence groove 4, the outer wall of the bottom plug 5 is attached to and pressed on the side wall of the bottom of the confluence groove 4, and the bottom of the confluence groove 4 is sealed by the bottom plug 5.
A plurality of copper outlet holes 6 which are obliquely arranged relative to the horizontal plane are formed in the side wall of the pipe body 1, all the copper outlet holes 6 are sequentially arranged along the circumferential direction of the pipe body 1, and the inner side openings of the copper outlet holes 6 are communicated with the confluence groove 4. The copper liquid in the confluence groove 4 flows out through the copper outlet holes 6, and the copper liquid cannot flow out from the bottom of the confluence groove 4, so that the copper liquid can form a round ingot.
The number of the copper outlet holes 6 is 4-18 in consideration of actual production requirements.
In the prior art, the copper hole 6 is not formed, the bottom plug 5 is not used, and the copper liquid directly flows out from the bottom of the confluence groove 4 to form a round ingot. Copper liquid outflow position shifts to out copper hole 6 by the bottom of groove 4 that converges in this embodiment, and all 6 outside opening total areas that go out copper hole compare groove 4 bottom areas that converge bigger, therefore the copper liquid in the body 1 can flow with faster velocity of flow, and the production efficiency of circle spindle obtains very big promotion.
In other embodiments, a plurality of copper outlet holes 6 can be additionally arranged along the axial direction of the shaft hole 3 to reduce the retention of the copper liquid in the pipe body 1.
The copper liquid can flow out from the copper outlet 6 as long as a certain amount of copper liquid is accumulated in the confluence groove 4. Preferably, the outer opening of the copper outlet 6 is located below the inner opening of the copper outlet 6, and the copper liquid can flow out of the copper outlet 6 more smoothly and quickly by using the self-gravity of the copper liquid.
The copper outlet hole 6 is a round hole. Considering the fluidity of the copper liquid, the included angle between the axis of the copper outlet 6 and the horizontal plane is 0-15 degrees.
The casting speed of the round ingot of this embodiment and the prior art is shown in table 1.
