[0026] Embodiment 1
[0027] Combination Figure 1-Figure 2 As shown, the utility model provides a chute equipment for ferroalloy casting, including two connected chutes, the first section is a fixed chute 2, the second section is a swing chute 4, the top of the fixed chute 2 is connected to the ladle 1, the bottom of the fixed chute 2 is connected to the top of the swing chute 4, and the swing chute 4 is located above the mold 9 to be cast.
[0028] The chute equipment for ferroalloy casting in this embodiment is applied to an alloy casting machine, which may be a step-by-step alloy casting machine, that is, the mold 9 moves forward in steps; it may be a uniform or variable speed alloy casting machine, such as a linear casting machine, a disc casting machine, a ring casting machine, etc., and the mold 9 moves forward at a uniform or variable speed; it may be a scene in which alloy casting is achieved in other ways, and the mold 9 moves at a uniform speed, variable speed or intermittently.
[0029] During operation, the ladle 1 pours the molten iron directly into the fixed chute 2, and the molten iron enters the swing chute 4 through the pouring channel of the fixed chute 2. The swing chute 4 evenly casts the molten iron on the mold 9 during swinging. The design of the swing chute 4 is conducive to uniform heating of the mold 9, and effectively avoids the fixed-point scouring of the casting mold 9 by the molten iron. After the swing chute 4 is set, the service life of the mold 9 is increased by more than 3 times compared with the traditional fixed-point casting method.
[0030] Combination Figure 1-Figure 2 As shown, the chute equipment for ferroalloy casting also includes a supporting steel structure frame 10 and a supporting steel structure frame 23. The bottom of the supporting steel structure frame 10 is set on the ground, and the bottom of the fixed chute 2 is set on the top of the supporting steel structure frame 10. The structural design of the supporting steel structure frame 10 is based on the size and weight of the fixed chute 2. The bottom of the supporting steel structure frame 23 is set on the ground, and the bottom of the swing chute 4 is rotatably connected to the supporting steel structure frame 23 through a chute swinger. The structural design of the supporting steel structure frame 23 is based on the size and weight of the swing chute 4.
[0031] Combination Figure 1-Figure 2 As shown, the fixed chute 2 is vertically arranged with the mold 9. The trough surface inclination angle of the fixed chute 2 ranges from 8° to 15°, preferably 10°, to meet the flow requirements of molten iron, while the flow speed of molten iron will not be too large, and will not cause a large impact on the swing chute 4.
[0032] Combination Figure 1-Figure 2 As shown, the runner of the swing chute 4 is arranged horizontally with the moving direction of the mold 9, and the direction of the molten iron discharged from the runner of the swing chute 4 is consistent with the moving direction of the mold 9, which can relatively reduce the speed scouring force of the molten iron on the mold 9. The inclination angle of the swing chute 4 is in the range of 8°-15°, preferably 10°, to meet the flow requirements of the molten iron. At the same time, the flow speed of the molten iron will not be too large, and will not cause a large impact on the mold 9.
[0033] By arranging the double chutes at right angles, the molten iron outlet of the swing chute 4 is consistent with the moving direction of the mold, which can relatively reduce the speed scouring force of the molten iron on the mold 9.
[0034] like Figure 1As shown, the mold 9 is arranged on the mold support, and a zero position detector 7 is arranged on the mold support. The zero position detector 7 adopts a setting trigger, and the zero position detector 7 is used to trigger the fixed detection point of the mold 9 that is running. The zero position detector 7 is arranged at the same position as the pouring outlet of the fixed chute 2 relative to the mold 9, that is, when the swing chute 4 just starts to swing, the trigger position of the zero position detection point of the zero position detector 7 is the same as the position of the molten iron outlet of the fixed chute 2; since the size of the ingot mold in the casting machine is the same, the fixed detection point of the zero position detector 7 is the outlet position of the fixed chute 2, and the fixed detection point for each mobile ingot mold is at the same position of the ingot mold, so that when the zero position detector 7 issues an instruction and the swing chute 4 starts to swing, it can be ensured that the chute swings on the mold 9 for one cycle, which is just completed in one mold 9.
[0035] like Figure 1 As shown, the zero position detector 7 is electrically connected to the synchronous swing instruction transceiver 6, which is arranged on the mold support and close to the supporting steel structure frame 23, and the synchronous swing instruction transceiver 6 adopts a programmable logic controller. When the zero position detector 7 detects the fixed detection point of the running mold 9 for the first time, the zero position detector 7 sends a detection drive system 8 stepping line speed signal to the synchronous swing instruction transceiver 6.
[0036] The synchronous swing instruction transceiver 6 is electrically connected to a drive system 8, which uses a motor or a hydraulic system as a driving mechanism. The synchronous swing instruction transceiver 6 is also electrically connected to a chute swinger, which is arranged at the bottom of the swing chute 4. The swing chute 4 rotates under the drive of the chute swinger. The drive system 8 is arranged on the mold support and is located on the left side of the zero position detector 7. The drive system 8 is used to drive the mold 9 to move forward and backward. After the synchronous swing instruction transceiver 6 receives the signal of detecting the stepping linear speed of the drive system 8 sent by the zero position detector 7, it starts to detect the stepping linear speed of the drive system 8 and feeds it back to the chute swinger. The synchronous swing instruction transceiver 6 controls the chute swinger to drive the swinging chute 4 to swing.
[0037] Combination Figure 2-Figure 3 As shown, the chute swinger includes a gear 12, a rack 11, and a hydraulically driven push rod 5 arranged on a supporting steel structure frame 23. The gear 12 is arranged at the bottom position of the molten iron inlet of the swing chute 4. The rack 11 is meshed and connected with the gear 12. One end of the rack 11 is connected to the hydraulically driven push rod 5. The hydraulically driven push rod 5 is electrically connected to the synchronous swing instruction transceiver 6. After receiving the stepping linear speed of the drive system 8 sent by the synchronous swing instruction transceiver 6, the chute swinger sets the speed of the hydraulically driven push rod 5 synchronously with the drive system 8, controls the hydraulically driven push rod 5 to reciprocate, drives the rack 11 to reciprocate, thereby drives the gear 12 to rotate back and forth, and then the gear 12 drives the swing chute 4 to swing back and forth.
[0038] Specifically, when the zero position detector 7 detects the fixed detection point of the running mold 9 for the first time, the zero position detector sends a signal to detect the stepping linear speed of the drive system 8 to the synchronous swing instruction transceiver 6. The synchronous swing instruction transceiver 6 quickly detects the stepping linear speed of the drive system 8 and sends the stepping linear speed of the drive system 8 to the chute oscillator. At this time, the chute oscillator drives the swing chute 4 to start swing casting. The swinging track formed by the swinging chute 4 on a single mold is as shown in FIG. Figure 4 shown.
[0039] Finally, when the molten iron flows out of the molten iron casting device of the ladle 1 and enters the swing chute 4 along the fixed chute 2, the swing chute 4 swings back and forth on the running mold 9, and the swing chute 4 evenly casts the molten iron on the mold 9 during the swinging.
[0040] In this embodiment, the synchronous swing instruction transceiver 6 sets the swing cycle of the swing chute 4 to be synchronized with the driving linear speed of the mold 9, that is, the swing cycle of the swing chute 4 is synchronized with the moving step of the single mold 9, such as Figure 4 shown.
[0041] The synchronous swing instruction transceiver 6 automatically scans the stepping speed of the drive system 8 every 0.5s. When the process adjusts the stepping speed of the drive system 8, the synchronous swing instruction transceiver 9 promptly calculates the swinging speed of the swinging chute 4 and sends the current speed to the chute swinger. The swinging chute 4 adjusts the speed in time to ensure that the stepping linear speed of the drive system 8 is synchronized with the swinging angular speed of the swinging chute 4.
[0042] In this embodiment, the stepping linear speed of the driving system 8 is used to guide the swinging angular speed of the swinging chute 4, and the swinging angular speed of the swinging chute 4 is guided to change with the change of the stepping linear speed of the driving system 8, so that the surface of the mold 9 is heated relatively evenly. The consumption of the mold 9 changes from the "linear burnout" of the fixed chute to the "overall surface burnout" of the swing chute, and the burnt surface is even.

[0045] The above technical features constitute the best implementation example of the present utility model, which has strong adaptability and best implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.
[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
