Description

Technical Field

[0001] The utility model relates to the field of casting and rolling mills, in particular to an aluminum liquid flow stabilizing device for a front box of a casting and rolling mill. Background Art

[0002] In the production process of aluminum casting and rolling, the fluctuation of the aluminum liquid level in the front box directly affects the quality of the rolled aluminum plate. At the same time, in order to ensure the continuity of the casting and rolling process, when the casting and rolling speed changes, the aluminum liquid flow rate also needs to change accordingly, so the accurate measurement and control of the front box liquid level is particularly important.

[0003] After searching the patent document with the announcement number CN208542952U, the patent document discloses "a device for stabilizing the flow of aluminum liquid in the front box of a casting and rolling mill, which drives the floating component to float through the fluctuation of the liquid level in the front box of the casting and rolling mill, and the floating of the floating component drives the two vertical bars and the cross bar to swing through the linkage rod, and the swing of the cross bar drives the plug assembly to control the opening size of the injection port, thereby controlling the flow size of the aluminum liquid injected into the front box of the casting and rolling mill, so as to achieve the purpose of stabilizing the flow";

[0004] Depending on the different products processed by the casting and rolling mill, the required flow rate of molten aluminum will also be different. Although the above-mentioned device has strong applicability by loosening the fastening component to adjust the height position of the connecting rod and the float, it is troublesome to tighten the fastening component after adjusting the float position. When the aluminum liquid drives the float and the connecting rod to float up, if the fastening component is not tightened, the connecting rod and the float will easily float vertically, resulting in the failure of the plug component to block the injection port. Utility Model Content

[0005] The purpose of the utility model is to provide an aluminum liquid flow stabilizing device for the front box of a casting and rolling mill in order to solve the above-mentioned problem.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] An aluminum liquid steady flow device for a front box of a casting and rolling mill comprises a bottom plate, a drainage groove is fixed on the upper end of one side of the bottom plate, and a front box;

[0008] The front box is fixed on the upper end of the bottom plate, and two bearing plates are fixed inside the front box. A slider is slidably connected between the two bearing plates, and a sliding tube is slidably connected in the middle of the slider. A limiting ring is fixed in the middle of the sliding tube, and a screw is connected to the internal thread of the sliding tube. A floating head is fixed at the lower end of the screw. A side extension frame is fixed at the lower end of the sliding tube, and a blocking head is fixed at the lower end of the side extension frame. A mounting frame is fixed at the upper end of the sliding tube, and a roller is rotatably connected in the middle of the mounting frame. An inclined panel is fixed at the upper end of the front box, and a pouring port is opened at the rear end of the front box, and a sealing cover is installed at the output end of the pouring port.

[0009] Preferably, the outer ring diameter of the roller is larger than the size of the mounting frame, and the outer ring diameter of the limiting ring is 2 centimeters larger than the outer ring diameter of the sliding tube.

[0010] Preferably, one end of the flow blocking head is in a cone shape.

[0011] Preferably, the inclined plate is arranged obliquely, and the lower end surface of the inclined plate is in contact with the outer ring of the roller.

[0012] Preferably, an injection pipe is fixed at one end of the drainage groove, the output end of the injection pipe extends into the front box, and the inclination angle of the line between the injection pipe and the plugging head is the same as the inclination angle of the inclined plate.

[0013] Preferably, the size of the injection pipe corresponds to the plugging head.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the aluminum liquid flows into the front box, the rising float of the aluminum liquid will push the floating head to float up through the sliding connection between the sliding tube and the slider. At this time, through the sliding connection between the slider and the bearing plate and the limiting of the roller by the inclined plate, when the floating head drives the screw and the sliding tube to float up, the entire floating structure can be moved toward the direction of the drainage groove, so that the blocking head can block the output port of the drainage groove to a certain extent, so that the amount of aluminum liquid flowing from the drainage groove into the front box can be controlled, thereby ensuring a smooth supply of aluminum liquid. Through the threaded connection between the sliding tube and the screw, the height position of the floating head in the front box can be adjusted by turning the screw or the floating head. This is not only more convenient but also does not need to consider the impact caused by whether it is locked. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 4 As shown, an aluminum liquid steady flow device for the front box of a casting and rolling mill includes a bottom plate 1, a drainage groove 3 is fixed on the upper end of one side of the bottom plate 1, and also includes a front box 2.

[0027] The front box 2 is fixed on the upper end of the bottom plate 1, and two bearing plates 21 are fixed inside the front box 2. A slider 22 is slidably connected between the two bearing plates 21, and a slide tube 23 is slidably connected in the middle of the slider 22. A limiting ring 24 is fixed in the middle of the slide tube 23, and the outer ring diameter of the limiting ring 24 is two centimeters larger than the outer ring diameter of the slide tube 23. A screw 25 is connected to the inner thread of the slide tube 23, and a floating head 26 is fixed at the lower end of the screw 25. A side extension frame 27 is fixed at the lower end of the slide tube 23, and a flow blocking head 28 is fixed at the lower end of the side extension frame 27. One end of the flow blocking head 28 is cone-shaped, and a mounting frame 29 is fixed on the upper end of the slide tube 23. A roller 210 is rotatably connected in the middle of the mounting frame 29. The outer ring diameter of the roller 210 is larger than the size of the mounting frame 29. An inclined panel 211 is fixed on the upper end of the front box 2. The inclined panel 211 is tilted, and the lower end surface of the inclined panel 211 fits the outer ring of the roller 210. A pouring port 212 is provided at the rear end of the front box 2, and a cover is installed at the output end of the pouring port 212; when the aluminum liquid flows into the front box 2, the floating of the aluminum liquid will push the floating head 26 to float up through the sliding connection between the sliding tube 23 and the slider 22. At this time, through the sliding connection between the slider 22 and the bearing plate 21 and the limiting of the roller 210 by the inclined plate 211, when the floating head 26 drives the screw 25 and the sliding tube 23 to float up, the entire floating structure can be moved toward the direction of the drainage groove 3, so that the blocking head 28 can block the output port of the drainage groove 3 to a certain extent, so that the amount of aluminum liquid flowing from the drainage groove 3 into the front box 2 can be controlled, thereby ensuring a stable supply of aluminum liquid, and through the threaded connection between the sliding tube 23 and the screw 25, when the screw 25 or the floating head 26 is rotated, the height position of the floating head 26 in the front box 2 can be adjusted, which is not only more convenient but also does not need to consider the influence caused by whether it is locked.

[0028] An injection pipe 31 is fixed at one end of the drainage trough 3, and the output end of the injection pipe 31 extends into the front box 2. The size of the injection pipe 31 corresponds to the flow blocking head 28, and the inclination angle of the line between the injection pipe 31 and the flow blocking head 28 is the same as the inclination angle of the inclined plate 211; through the setting of the injection pipe 31, the aluminum liquid in the drainage trough 3 can flow into the front box 2 through the injection pipe 31.

[0029] Working principle: After the aluminum liquid flows into the front box 2 from the drainage groove 3, the sliding connection between the slide tube 23 and the slider 22 causes the floating head 26 to float upward due to the rising of the aluminum liquid. At this time, through the sliding connection between the slider 22 and the bearing plate 21 and the limiting of the roller 210 by the inclined plate 211, when the floating head 26 drives the screw 25 and the slide tube 23 to float upward, the entire floating structure can be moved toward the direction of the drainage groove 3, so that the blocking head 28 can block the output port of the injection pipe 31 to a certain extent, so that the amount of aluminum liquid flowing from the drainage groove 3 into the front box 2 can be controlled, thereby ensuring a smooth supply of aluminum liquid. Through the threaded connection between the slide tube 23 and the screw 25, the height of the floating head 26 in the front box 2 can be adjusted by rotating the screw 25 or the floating head 26. This is not only more convenient, but also does not need to consider the impact caused by whether it is locked.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
