Description

Technical Field

[0001] The utility model relates to the technical field of aluminum silicon ingot melting, in particular to a slag blocking device for an aluminum silicon plating pre-melting pot. Background Art

[0002] With the demand of the automobile market, aluminum-silicon plate has been widely recognized and applied for its excellent corrosion resistance and heat resistance, which are higher than galvanized plate, and these excellent characteristics are closely related to the quality of the coating on the surface of the substrate. In order to prevent the aluminum-silicon slag from directly melting in the aluminum-silicon pot, causing surface plating defects such as leakage, color difference, and large aluminum particles, thereby affecting the above-mentioned characteristics of the product surface, the continuous hot-dip aluminum-silicon production line is generally equipped with a pre-melting pot system to melt the aluminum-silicon alloy ingot into aluminum-silicon liquid in the pre-melting pot. After the aluminum-silicon ingot is added, when the liquid level of the aluminum-silicon liquid is higher than the nozzle of the upper section of the chute, it overflows through the nozzle, enters the chute, and is transported to the aluminum-silicon pot. In this way, the aluminum-silicon liquid in the aluminum-silicon pot can ensure uniform temperature and composition, and can reduce the content of aluminum-silicon slag or aluminum-silicon particles.

[0003] Since melting aluminum silicon ingots will inevitably produce aluminum silicon slag, the aluminum silicon slag in the pre-melting pot has a relatively small density and floats on the surface of the aluminum silicon liquid. When the aluminum silicon liquid overflows from the nozzle hole, the aluminum silicon slag enters the chute with the aluminum silicon liquid and then enters the aluminum silicon pot. Since the aluminum silicon slag entering the aluminum silicon pot is mostly semi-solidified and floats on the liquid surface, it is very easy to affect the surface quality of the coating, causing defects such as missed plating and large aluminum particles.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1-2 The utility model provides a technical solution for a slag blocking device for an aluminum-silicon pre-melting pot: a slag blocking device for an aluminum-silicon pre-melting pot, comprising:

[0020] An arc-shaped slag blocking plate 1, both ends of which are attached to the inner wall of the premelting pot 10, and are used to block the slag at the nozzle 20 on the premelting pot 10;

[0021] The connecting plate 2 is symmetrically mounted at both ends of the arc-shaped slag-blocking plate 1, and the connecting plate 2 is used to connect and install the arc-shaped slag-blocking plate 1 and adjust the height of the arc-shaped slag-blocking plate 1;

[0022] The crossbeam 3 is fixedly connected to the side wall of the connecting plate 2 facing away from the arc-shaped slag blocking plate 1 , and the crossbeam 3 is used to install the device on the premelting pot 10 .

[0023] In this embodiment, by setting the arc-shaped slag baffle plate 1, the two side walls of the arc-shaped slag baffle plate 10 are in contact with the inner wall of the pre-melting pot 10, and the bottom of the arc-shaped slag baffle plate 1 is lower than the lowest point of the chute 20. The aluminum silicon ingot is put into the pre-melting pot for melting, and the liquid level of the aluminum silicon liquid continues to rise. When it is higher than the lowest point of the chute, the aluminum silicon liquid overflows from the chute into the chute. The bottom edge of the arc-shaped slag baffle plate 1 is lower than the lowest point of the chute. When the aluminum silicon liquid overflows, the arc-shaped slag baffle plate 1 The bottom edge of plate 1 is lower than the liquid level of aluminum silicon liquid. The liquid level of aluminum silicon liquid around the nozzle 20 is blocked by the arc-shaped slag blocking plate 1. The semi-solidified aluminum silicon slag floating on the liquid level of aluminum silicon liquid is blocked outside the arc-shaped slag blocking plate 1. The aluminum silicon liquid below the liquid level flows to the nozzle through the cavity surrounded by the bottom edge of the slag blocking plate and the inner wall of the pre-melting pot. The aluminum silicon slag floating on the liquid surface cannot reach the nozzle, and will not enter the chute, and will not enter the aluminum silicon pot. The arc-shaped slag blocking plate 1 and the elliptical cavity surrounded by the inner wall of the pre-melting pot ensure that the overflowing aluminum silicon liquid can stably flow out from the chute 20. The arc slag baffle plate 1 is horizontally welded and fixed on the connecting plate 2 by providing a connecting plate 2. Since the temperature of the aluminum silicon liquid is very high, the temperature of the arc slag baffle plate 1 directly in contact with the aluminum silicon liquid and the connecting plate 2 connected to the arc slag baffle plate 1 are also very high. Continuous high temperature is likely to reduce the service life of the equipment. At the welding point between the two, there are multiple gaps to facilitate heat dissipation. When used for a long time, the bottom of the arc slag baffle plate 1 will be slowly melted and eroded, so it is convenient to cut the connection between the arc slag baffle plate 1 and the connecting plate 2, move the arc slag baffle plate 1 downward and re-weld it on the connecting plate 2, which is convenient for repeated use and reduces material waste. Because the temperature of the aluminum silicon liquid is very high, other complex structures are not applicable. By providing a crossbeam 3, it is convenient to fix it on the pre-melting pot 10 through the crossbeam 3, thereby improving the stability of the structure and ensuring the normal operation of the device.

[0024] Furthermore, the arc-shaped slag retaining plate 1 is in an arc shape.

[0025] In this embodiment, the elliptical cavity formed by the arc-shaped slag baffle plate 1 and the inner wall of the pre-melting pot ensures that the overflowing aluminum silicon liquid can stably flow out from the nozzle 20.

[0026] Typically, the arc-shaped slag retaining plate 1 is made of a corrosion-resistant and heat-resistant stainless steel plate.

[0027] In this embodiment, the arc-shaped slag retaining plate 1 is made of a corrosion-resistant and heat-resistant stainless steel plate, thereby increasing the service life of the equipment.

[0028] Specifically, the connecting plate 2 and the crossbeam 3 are made of ordinary carbon steel.

[0029] In this embodiment, the service life of the equipment is increased.

[0030] In addition, the arc-shaped slag baffle plate 1 is fitted with the inner wall of the premelting pot 10 in a clearance fit, and the clearance distance is not greater than 10 mm.

[0031] In this embodiment, the arc-shaped slag baffle plate 1 and the inner wall of the pre-melting pot 10 are fitted with a gap, and the gap is not greater than 10 mm. In order to achieve the best slag-blocking effect, the arc-shaped slag baffle plate 1 and the inner wall of the pre-melting pot 10 can be sealed and connected. However, the high temperature of the aluminum-silicon liquid will cause thermal deformation of the metal components such as the arc-shaped slag baffle plate 1, which may cause the sealed connection to be subjected to greater stress and stress changes caused by temperature changes, which will make the structure vulnerable and require frequent replacement and maintenance. In order to avoid this situation, the slag baffle plate and the inner wall of the pre-melting pot may not be sealed, and a certain gap may be left to allow for deformation. Even if a gap of 10 mm is left, the aluminum-silicon slag is semi-solidified, sticky, and has poor fluidity. The aluminum-silicon slag cannot flow through the gap, but is blocked at the gap to fill the gap.

[0032] It should be noted that two groups of connecting plates 2 and cross beams 3 are provided and symmetrically installed at both ends of the arc-shaped slag retaining plate 1.

[0033] In this embodiment, two sets of connecting plates 2 are installed on both sides of the arc-shaped slag retaining plate 1, so as to facilitate the connection, installation and adjustment of the height of the arc-shaped slag retaining plate 1. Two sets of cross beams 3 are installed on the connecting plates 2 on both sides of the arc-shaped slag retaining plate 1, so as to facilitate the connection and installation with the pre-melting pot 10, thereby improving the stability of the structure and ensuring the normal operation of the device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
