Description

Technical Field

[0001] This utility model relates to the field of high-temperature alloy material manufacturing technology, specifically to a high-efficiency and stable-flow casting chute. Background Technology

[0002] In the current field of industrial mass production of high-temperature alloy master alloys, the melting equipment and diversion methods of high-temperature alloy master alloys are strongly correlated with indicators such as production efficiency, alloy one-time casting yield, and alloy purity. For mass production equipment, the importance of the sluice—the first device receiving the steel from the crucible—is self-evident. Currently, the mainstream production mode is: molten alloy is discharged from the crucible, introduced into the sluice for stabilization, injected into the diversion plate, and then injected into the mold tube.

[0003] Conventional industrial casting chutes typically consist of a single feed chamber and a single pouring port. Molten alloy is poured in from the feed chamber, flows along the chute, and exits from the pouring port. Due to the short flow path, the filtration time is limited, necessitating higher casting temperatures to ensure fluidity. However, this also reduces the time required for slag to float, affecting alloy purity and increasing production costs. Furthermore, existing casting chutes, with only one pouring port, can only process one distribution plate and corresponding mold at a time, resulting in low production line utilization and limited output per unit time. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency, stable-flow casting chute that can increase the flow path of the alloy liquid, effectively improve the stable flow performance of alloy casting, expand the flow contact area of ​​the alloy liquid, thereby increasing the slag flotation rate and improving the alloy purity. It can also process two distribution plates and corresponding molds at the same time, significantly increasing the output per unit time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-efficiency and stable-flow casting chute, comprising a chute body, a filter sheet provided in the chute body along its width direction, an inclined surface provided on the inner bottom surface of the chute body, two sets of flow guides arranged sequentially on the inclined surface along the flow direction of the alloy liquid, each set of flow guides including at least one curved flow guide protrusion arranged along the width direction of the chute body, a flow diversion protrusion provided on the inner bottom surface of the chute body along its length direction, the distance between the two sides of the flow diversion protrusion and the two side walls of the chute body is equal, one end of the flow diversion protrusion is connected to the chute body, and the other end is connected to the curved flow guide protrusion at the lowermost end of the inclined surface, and pouring ports are symmetrically provided on both sides of the flow diversion protrusion.

[0006] A further improvement of this utility model is that the two sets of flow guides are sequentially divided into a first flow guide and a second flow guide along the flow direction of the alloy liquid. The curved flow guide protrusion of the second flow guide includes a middle section and flow branch sections located on both sides of the middle section. The cross-section of the flow branch section gradually increases from the end away from the middle section to the end closer to the middle section until it is consistent with the cross-section of the middle section.

[0007] A further improvement of this utility model is that the cross-section of the end of the diversion section away from the middle section is consistent with the cross-section of the curved guiding protrusion of the first guide member, and the cross-section of the middle section is larger than the cross-section of the curved guiding protrusion of the first guide member.

[0008] A further improvement of this utility model is that each set of guide elements includes two curved guide protrusions.

[0009] A further improvement of this utility model is that at least one stepped surface is coaxially provided inside the pouring port, and a filter screen is provided on the stepped surface.

[0010] A further improvement of this utility model is that one end of the diversion protrusion is embedded in the curved guide protrusion.

[0011] A further improvement of this utility model is that the inclination angle of the inclined surface is 12-15°, and the filter sheet is inclined with an inclination angle of 65-70°.

[0012] A further improvement of this utility model is that the opposite side walls of the tank are provided with slots, and the filter sheet is snapped and fixed between the two slots with its lower end abutting against the inclined surface.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention features multiple flow guides. The curved flow guides increase the flow path of the molten alloy, effectively improving the flow stability of the alloy casting, expanding the flow contact area of ​​the molten alloy, thereby increasing the slag flotation rate and improving the purity of the alloy.

[0015] This utility model is equipped with two pouring ports. The alloy liquid can be divided by the combination of the diversion protrusion and the diversion section. The distance between the two sides of the diversion protrusion and the tank wall is the same, which can ensure that the fluid or material is evenly divided into two or more streams after entering the tank, thereby improving the efficiency and quality of subsequent processing. It can process two diversion plates and corresponding molds at the same time, significantly increasing the output per unit time.

[0016] The filter of this utility model is inclined, which effectively ensures that the alloy liquid completes the initial slag filtration and flows smoothly into the arched flow channel, improving the alloy flow stability of the chute and guiding it to the diversion plate.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: Combination Figures 1-3 It is known that a high-efficiency and stable-flow casting chute includes a trough body 1, a filter plate 2 is provided in the trough body 1 along its width direction, an inclined surface 3 is provided on the inner bottom surface of the trough body 1, two sets of flow guides are arranged sequentially on the inclined surface 3 along the flow direction of the alloy liquid, each set of flow guides includes at least one curved flow guide protrusion 4 arranged along the width direction of the trough body 1, a flow diversion protrusion 5 is provided on the inner bottom surface of the trough body 1 along its length direction, the distance between the two sides of the flow diversion protrusion 5 and the two side walls of the trough body 1 is equal, one end of the flow diversion protrusion 5 is connected to the trough body 1, and the other end is connected to the curved flow guide protrusion 4 at the lowermost end of the inclined surface 3, and pouring ports 6 are symmetrically provided on both sides of the flow diversion protrusion 5.

[0023] The two sets of flow guides are sequentially divided into a first flow guide and a second flow guide along the flow direction of the molten alloy. The curved flow guide protrusion 4 of the second flow guide includes a middle section 7 and flow diversion sections 8 located on both sides of the middle section 7. The cross-section of the flow diversion section 8 gradually increases from the end away from the middle section 7 to the end closer to the middle section 7 until it matches the cross-section of the middle section 7. This facilitates the diversion of the molten alloy. Preferably, one end of the flow diversion protrusion 5 is embedded in the curved flow guide protrusion 4.

[0024] The cross-section of the end of the diversion section 8 away from the middle section 7 is consistent with the cross-section of the curved guide protrusion 4 of the first guide member, and the cross-section of the middle section 7 is larger than the cross-section of the curved guide protrusion 4 of the first guide member.

[0025] Preferably, each set of guide elements includes two curved guide protrusions 4.

[0026] The pouring gate 6 has at least one coaxial stepped surface 9, on which a filter screen is installed. Optionally, the pouring gate 6 has two stepped surfaces, on which two filter screens are installed, with the through-hole diameter of the lower filter screen being smaller than that of the upper filter screen. Preferably, the pouring gate 6 is a tapered pouring gate.

[0027] The inclination angle of the inclined plane 3 is 12-15°, which effectively reduces the amount of steel stored. The filter plate 2 is set at an inclination angle of 65-70°.

[0028] Preferably, the inner side walls of the tank 1 are provided with slots 10, and the filter sheet 2 is snapped and fixed between the two slots 10 with its lower end abutting against the inclined surface 3. The filter sheet 2 can be disassembled and replaced as needed.

[0029] The working principle of the high-efficiency and stable-flow casting chute provided by the utility model is as follows: When in use, the alloy liquid is poured into the tank 1. After being filtered by the filter, the alloy liquid flows along the inclined surface 3. The curved guide protrusion increases the flow path, effectively improving the stable flow performance of alloy casting and expanding the flow contact area of ​​the alloy liquid, thereby increasing the slag flotation rate. The alloy liquid flows smoothly forward. When it reaches the second guide component, it is initially divided by the diversion section 8, and then divided into two streams by the diversion protrusion 5. The streams flow along both sides of the diversion protrusion 5 to the two pouring holes, and then are injected into the mold tubes under the two diversion plates.
