Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, and small amounts of carbon and other elements. It is a ferroalloy with a wide range of uses and high production volume.

[0044] A method for producing a silicon-manganese alloy comprises the following steps:

[0045] S1. Before pouring, confirm that the silicon-manganese alloy casting device is clean and working properly, clean the inner brick shell inside the ladle shell and the inner brick tube inside the iron nozzle to ensure that there are no foreign objects, and then move the silicon-manganese alloy casting device to the position where the molten iron is poured into the submerged arc furnace;

[0046] S2, adding the silicon-manganese alloy into a submerged arc furnace for smelting to obtain a silicon-manganese alloy melt, and at the same time cleaning the ingot mold and applying a release agent, and preheating the ingot mold;

[0047] S3, at this time, the lifting mechanism drives the ladle shell and the sealing protection mechanism connected thereto to move up and down and adjust to the appropriate position. The trapezoidal cover connected to the movable cover in the sealing protection mechanism is separated from the ladle shell and away from it, and the silicon-manganese alloy melt in the submerged arc furnace is poured into the inner brick shell connected to the ladle shell. At this time, the sealing protection mechanism again seals the upper part of the ladle shell through the cooperation of the movable cover and the trapezoidal cover, thereby ensuring the safe and stable movement of the silicon-manganese alloy casting device;

[0048] S4, after the silicon-manganese alloy casting device moves to the ingot mold, the trapezoidal plug connected to the sealing cover in the plugging mechanism is separated from the molten iron nozzle, and at the same time, the third cylinder drives the L-shaped movable plate to rotate upward, and at the same time, the solenoid valve in the sealing protection mechanism 3 is opened, so that the silicon-manganese alloy melt in the silicon-manganese alloy casting device can be stably poured into the ingot mold;

[0049] S5. After the silicon-manganese alloy melt is cooled, the silicon-manganese alloy ingot is separated from the ingot mold and stored in the warehouse after passing the inspection.

[0050] Working principle: When the silicon-manganese alloy casting device is used, the lifting mechanism 2 can support the ladle shell 1, and the side support mechanism 4 can support the sealing protection mechanism 3. The cooperation of the first walking wheel 209 and the second walking wheel 402 can ensure the overall movement of the device. The device can be moved by pulling without lifting. In the lifting mechanism 2, the first stepper motor 208 drives the sprocket 206 to drive the lifting screw 203, and then drives the connecting block 205 to move up and down through the moving block 204, which can drive the ladle shell 1 to move up and down. At the same time, the outer frame 302 in the sealing protection mechanism 3 is connected to the limiting slider 404 in the side support mechanism 4. When the ladle shell 1 moves up and down, the limiting slider 404 slides in the limiting slide groove 403 opened in the side bracket 401 to ensure the overall lifting and adjustment of the device;

The silicon-manganese alloy melt can be poured into the inner brick shell 7 connected to the ladle shell 1. The first cylinder 303 on the outer frame 302 in the sealing protection mechanism 3 drives the support plate 304 to move, and the second convex sliding block connected to the support plate 304 slides in the second convex chute opened in the outer frame 302. When the support plate 304 moves to above the ladle shell 1, the second cylinder 305 on the support plate 304 extends to act on the movable cover 309, which can make the trapezoidal cover 310 connected to the movable cover 309 move downward to block the port of the ladle shell 1. During this process, the first baffle 308 connected to the first movable column 306 acts on the first return spring 307 to compress it, and the port of the ladle shell 1 is sealed to ensure the safety of the transportation process.

[0052] When casting silicon-manganese alloy, the second stepper motor 605 in the receiving protection mechanism 6 drives the driving gear 606 to act on the rack 603, so that the convex connecting strip 602 moves in the limiting sleeve 601, and the receiving inclined box 607 extends. At this time, in the plugging mechanism 5, the fifth cylinder 509 is shortened, and with the cooperation of the second return spring 512 and the second baffle 511, the second movable column 510 drives the sealing cover 514 and the trapezoidal plug 515 to separate from the molten iron nozzle 8. At this time, the third cylinder 504 contracts, and the L-shaped movable plate The rotating shaft 502 connected to 503 rotates in the vertical rod 501 to open the molten iron nozzle 8. At the same time, the second stepper motor 605 drives the driving gear 606 to act on the rack 603 again, and then retracts the receiving inclined box 607 to ensure the discharge of the silicon-manganese alloy melt and the progress of casting. The receiving inclined box 607 can receive the dripping silicon-manganese alloy melt. The arc-shaped blocking bar 609 cooperates with the straight blocking bar 610 to ensure the sealing of the arc-shaped liquid collecting tank 608, which is convenient for personnel to recycle materials and improve the safety of the production process.
