Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, and in particular to a slag-blocking ring for casting aluminum alloy square bars. Background Technology

[0002] In the casting process of aluminum alloy square bars, the molten aluminum liquid is filtered through a glass bag and then enters the crystallizer for casting. Due to fluctuations in the liquid level, the molten aluminum liquid will tumble when it enters the crystallizer, and slag, which may contain oxide slag, will be carried into the crystallizer. Directly casting the molten aluminum liquid with such impurities as slag results in low quality of the formed aluminum alloy square bars.

[0003] A common solution is to use slag-blocking rings to control the slag and oxide scale on the surface of the molten aluminum in the crystallizer within a fixed range. However, slag-blocking rings are often suspended by chains, which lack limiting and are highly mobile. They are prone to continuous shaking under the impact of molten aluminum, resulting in fluctuations that affect the slag-blocking effect. In addition, during the continuous introduction of molten aluminum, the water level changes frequently but randomly, and the large fluctuations in water level cause the floating of the slag-blocking ring to have a certain delay, which can easily lead to slag leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a slag-blocking ring for casting aluminum alloy square bars, which can assist in the vertical linear sliding of the slag-blocking ring body to avoid the problem of continuous shaking of the slag-blocking ring body during the impact of molten aluminum, and maintain its position stability. In addition, it can monitor the liquid level in real time and adaptively adjust the vertical mounting height of the slag-blocking ring in real time.

[0005] To achieve the above objectives, a slag-blocking ring for casting aluminum alloy square bars is provided, comprising: a slag-blocking ring body, wherein several pads are symmetrically fixed on the front and rear sides of the slag-blocking ring body, and a limiting telescopic rod is fixedly connected to the top center of each pad, wherein the limiting telescopic rod located on the rear left side of the slag-blocking ring body is replaced by an electric push rod, and the bottom output end of the electric push rod is fixedly connected to the pad directly below it, wherein a sensor controller is built into the electric push rod, and a float level monitor is mounted on the left side of the electric push rod, wherein the float level monitor is embedded downward into the inner wall of the slag-blocking ring body and fixed thereto, and a float rod is slidably fitted up and down on the inner side of the float level monitor, wherein the float rod is vertically fitted downward into the inner wall of the slag-blocking ring body. The slag-blocking ring slides downwards into the lower side of the main body, with a float fixedly connected to its end. The float level monitor is electrically connected to the sensor controller of the electric push rod. Abandoning the traditional chain-type hoisting method, a limit telescopic rod is used in conjunction with the electric push rod to assist in the vertical linear sliding erection of the slag-blocking ring main body. This avoids the problem of continuous shaking of the slag-blocking ring main body during the impact of molten aluminum, keeping its position stable. In addition, the float level monitor is set up in conjunction with the float rod and float ball to monitor the liquid level in real time. Then, it is electrically connected to the electric push rod to adaptively adjust the vertical erection height of the slag-blocking ring main body in real time, avoiding slag leakage caused by water level fluctuations and improving the flexibility of slag blocking operation.

[0006] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, a retaining sleeve is fixedly engaged along the upper inner edge of the slag-blocking ring body. The retaining sleeve is made of a high-temperature resistant elastic material. This buffers and isolates the slag, reducing its wear on the slag-blocking ring body, and allows for independent disassembly and replacement, extending the service life of the slag-blocking ring body.

[0007] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, an outer protective ring is symmetrically mounted on the upper outer side of the main body of the slag-blocking ring. The two ends of the opposite side of the outer protective ring are respectively fixedly connected to a pad and a float level monitor. This provides double-barrier protection and improves isolation strength.

[0008] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, a limiting rod is fixedly connected to each of the left and right opposite sides of the pad, and the limiting rod is made of a bending-resistant material. This maintains the overall stability of the slag-blocking ring's shape.

[0009] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, a counterweight washer is fixedly arranged around the lower inner edge of the slag-blocking ring body. This lowers the overall center of gravity of the slag-blocking ring to maintain the overall horizontal stability of the installation and prevents significant tilting or fluctuations.

[0010] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, a rectangular mounting frame is engaged and fixed to the top outer side of the electric push rod and the limiting telescopic rod. This facilitates the combination of the electric push rod and several limiting telescopic rods into a single unit for installation, maintaining the uniformity of their output direction.

[0011] According to the aforementioned slag-blocking ring for casting aluminum alloy square bars, the outer side of the top end of the limiting telescopic rod is engaged and fixed with a limiting ring sleeve, and the outer side of the limiting ring sleeve is correspondingly fixedly connected to a rectangular mounting frame. This provides vertical limitation between the limiting telescopic rod and the mounting frame.

[0012] According to the aforementioned aluminum alloy square bar casting slag-blocking ring, the rectangular mounting frame has symmetrical mounting grooves on its left and right sides. It can be used with a flat plate with several bolts to horizontally mount the rectangular frame directly above the slag-blocking ring body.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] This invention abandons the traditional chain-type hoisting method and adopts a limit telescopic rod in conjunction with an electric push rod to assist in the vertical linear sliding erection of the slag-blocking ring body. This avoids the problem of continuous shaking of the slag-blocking ring body during the impact of molten aluminum and keeps its position stable. In addition, a float water level monitor is set up in conjunction with a float rod and a float ball to monitor the liquid level in real time. Then, the electric push rod is used to adaptively adjust the vertical erection height of the slag-blocking ring body in real time, avoiding slag leakage caused by water level fluctuations and improving the flexibility of slag blocking operation.
