Description

Technical Field

[0001] The utility model belongs to the technical field of alloy casting, and in particular relates to an alloy casting auxiliary tooling. Background Art

[0002] Casting refers to an alloy processing technology that pours alloy liquid into a mold and then cools it to form. The current mainstream casting technology uses a casting tool transition during the production process, that is, the molten metal is first poured into the casting tool, and then poured into the mold by the casting tool. Its main purpose is to isolate the oxide slag on the surface of the molten metal.

[0003] Traditional casting tooling spouts are directly introduced vertically into the mold. When casting is about to end, the last part of the molten metal forms a vortex at the tooling spout under the action of gravity, causing a large amount of oxide slag on the surface of the molten metal to flow into the mold together and unavoidably, resulting in the output ingot mixed with oxide slag, affecting its performance. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide an alloy casting auxiliary tooling, which can reduce the oxide slag content of alloy ingots produced by casting.

[0005] The utility model embodiment is achieved in this way:

[0006] An alloy casting auxiliary tooling comprises: a cavity for accommodating alloy liquid, wherein the cavity is semi-cylindrical in shape as a whole;

[0007] The two ends of the cavity are welded with hanging ears, and a pull rod is welded on the hanging ear at one end;

[0008] A plurality of heating holes are provided in the cavity wall of the cavity, and a corresponding number of heating tubes are embedded and installed in each of the plurality of heating holes; a thermocouple hole is provided in the cavity wall of the cavity, and a thermocouple is embedded in the thermocouple hole;

[0009] A nozzle is welded at the bottom end of the cavity, which is connected to the space inside the cavity. A pipe extending along the inner wall of the cavity is provided at the junction of the nozzle and the cavity. The starting end of the pipe is located at the bottom end of the cavity, and the end thereof is connected to the nozzle.

[0010] The plurality of heating holes are respectively distributed near two ends of the cavity and are spaced apart along the cross-sectional circumference of the cavity.

[0011] Wherein, the nozzle is inclined at an angle to the cavity.

[0012] Among them, there are 7 heating tubes.

[0013] Wherein, the overall shape of the hanging ear is cylindrical.

[0014] The embodiment of the utility model heats the entire cavity by inserting a heating tube into the heating hole, so that the molten metal remains in a liquid state when poured into the cavity to facilitate casting, and the cavity temperature is controlled by controlling the temperature of the heating tube; during the production process, the alloy casting auxiliary tooling can control the amount of molten metal flowing into the mold, and the alloy liquid in the alloy casting auxiliary tooling can be controlled to flow out by pulling the pull rod. When the page is about to drop to the leakage nozzle, the pull rod can be pulled back to allow the oxide slag floating on the surface of the molten metal to remain in the cavity, thereby effectively reducing the amount of oxide slag flowing into the mold, greatly reducing the oxide slag content of the produced ingot, and effectively controlling the oxide slag content of the alloy ingot produced by casting; at the same time, the alloy casting auxiliary tooling can control the flow rate of the molten metal flowing into the mold, and the flow rate can be controlled by changing the inclination angle of the pulling rod, which can increase the controllability of the process.

[0019] 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.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0021] like Figures 1 to 4 As shown, an alloy casting auxiliary tooling comprises: a cavity 1 for accommodating alloy liquid, wherein the cavity is in a semi-cylindrical shape as a whole;

[0022] The two ends of the cavity are welded with hanging ears 5, and a pull rod 6 is welded on the hanging ear at one end;

[0023] A plurality of heating holes are opened in the cavity wall of the cavity, and a corresponding number of heating tubes 2 are embedded and installed in the plurality of heating holes respectively; a thermocouple hole is opened in the cavity wall of the cavity, and a thermocouple 3 is embedded in the thermocouple hole;

[0024] A nozzle 4 is welded at the bottom of the cavity, and the nozzle is connected to the space inside the cavity. A pipe extending along the inner wall of the cavity is provided at the junction of the nozzle and the cavity. The starting end of the pipe is located at the bottom of the cavity, and the end thereof is connected to the nozzle. Figure 4 Due to the existence of the pipeline, the oxide slag floating on the surface of the alloy liquid is not easy to enter the pipeline during casting, thus ensuring the casting quality.

[0025] Figure 1 and Figure 3 In the embodiment, the plurality of heating holes are respectively distributed near two ends of the cavity and are spaced apart along the cross-sectional circumference of the cavity.

[0026] Figure 2 and Figure 4 In the embodiment, the nozzle is inclined at an angle to the cavity.

[0027] Figure 3 In the embodiment, the number of the heating tubes is 7. The number of the heating tubes may be more as long as they are evenly distributed on the cavity and the heating effect is satisfactory.

[0028] Figure 3 In the embodiment, the hanging ear is in a cylindrical shape as a whole.

[0029] All parts of the utility model are made of 304 stainless steel, and all parts are connected and installed by arc welding. When in use, the alloy casting auxiliary tooling is fixed below the front end of the smelting furnace through the hanging ear 5, so that when the smelting furnace is tilted, the alloy liquid can be poured into the casting auxiliary tooling cavity 1, and the nozzle 4 is just above the casting mold; 7 heating tubes 2 are installed in the heating hole, which can be powered to heat the cavity to keep a certain temperature in the cavity so that the alloy liquid does not solidify in the cavity; a thermocouple 3 is installed in the thermocouple hole, which can monitor the temperature in the cavity in real time; when casting, pull the pull rod 6 to tilt the casting auxiliary tooling at a certain angle, and the alloy liquid in the cavity is drained into the mold through the nozzle. Since the connection port between the nozzle and the cavity is located at the bottom of the cavity, the oxide slag floating on the surface of the alloy liquid can be effectively prevented from flowing into the mold along the channel. When the liquid level drops to almost reach the same level as the nozzle, the pouring is stopped and the casting is completed.

[0030] In an embodiment of the utility model, a heating tube is inserted into the heating hole to heat the entire cavity so that the molten metal remains in a liquid state when poured into the cavity to facilitate casting, and the cavity temperature is controlled by controlling the temperature of the heating tube. A thermocouple is inserted into the thermocouple hole to facilitate real-time monitoring of the cavity temperature and precise control of the cavity temperature. The molten metal is poured into the mold through a leak nozzle for casting. The device is fixed under the front end of the casting furnace through a hanging ear, and the pull rod is installed on the hanging ear at the longer end. The rotation of the cavity is controlled by pulling the pull rod to pour the molten metal into the mold. In this way, during the production process, the alloy casting auxiliary tooling can control the amount of molten metal flowing into the mold, thereby effectively reducing the amount of slag flowing into the mold, so that the slag content of the ingot produced is greatly reduced, and the alloy casting auxiliary tooling can control the flow rate of the molten metal flowing into the mold, which can increase the controllability of the process.

[0031] 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.
