Technical Field

The invention belongs to the technical field of electro-slag metallurgy deoxidation alloying, and particularly relates to a metal bar feeding device for electro-slag metallurgy and an adding system thereof.

Background

Electroslag metallurgy is a casting process and a purification and refining process, and can better purify metals and obviously remove nonmetallic inclusions. A large number of practices show that oxide inclusions in steel have a direct relation with oxygen content, and active elements such as Al, Ti, Ce, B and the like in the steel are often lost due to oxidation in the remelting process. How to prevent the oxidation of active elements is one of the important metallurgical problems of electroslag remelting. The electroslag remelting process is generally carried out in an atmospheric atmosphere, and a slag pool continuously absorbs oxygen from air and transfers the oxygen to a molten pool in the remelting process, which is actually equivalent to an oxidation process, so that the oxygen content of the remelted electroslag ingot is extremely higher than the self-power consumption, and the metallurgical quality of the steel ingot is reduced. The reduction of oxygen in an electroslag ingot is a big problem of electroslag remelting, and in order to reduce the oxygen content in the electroslag ingot and improve the metallurgical quality of the electroslag ingot, the currently generally adopted method is as follows: vacuum arc remelting, inert gas protection electroslag remelting, compound deoxidizer oxygen removal and the like. The steel ingot remelted by the vacuum arc has high purity, uniform and compact structure, but the equipment is complex and the maintenance cost is high, so that the alloy production cost is high; although the inert gas protection electroslag remelting method can effectively prevent oxygen absorption in the electroslag remelting process and reduce the oxygen content in an electroslag ingot, the inert gas protection is not easy to adopt due to the uniqueness of electroslag remelting furnace equipment; the inclusions generated by the consumable electrode produced by Al final deoxidation are not easy to separate out in the electroslag remelting process, so that a composite deoxidizer is used for replacing Al deoxidation, but the technology is still immature, other inclusions can be generated in the deoxidation process, and the effect is not obvious enough. Compared with the method, Al is a preferred choice for deoxidation by directly adding Al in the electroslag remelting process, aluminum is used as a strong deoxidation element, and most of the electroslag remelting process adopts aluminum or aluminum-containing composite deoxidizers for deoxidation. Wherein, the aluminum wire is used as a common deoxidizer and has the advantages of simple obtaining process, low price and the like.

The Chinese patent 'a three-cylinder linkage wire feeder (application number: CN201820630463. X)', which discloses a three-cylinder linkage wire feeder, comprising a wire feeder body, a wire feeder action cylinder, a trolley action cylinder, a wire feeder trolley, a lifting cylinder, a lifting slideway, a large conduit and a pulley block. The large guide pipe is vertically arranged, the outer side wall of the large guide pipe is fixedly connected with the belt pulley, the push rod head of the lifting cylinder is connected with the belt pulley through a hinge, the tail end of the cylinder body of the lifting cylinder is fixed with the lifting slideway through a hinge, and the belt pulley is in rolling connection with the lifting slideway through a clamping roller, so that the large guide pipe can be lifted along the lifting slideway without derailing; the lifting slide rail and the wire feeding trolley are of an integral steel structure, the wire feeding trolley is seated on the floor of the working platform through a walking roller, a push rod head of a trolley action cylinder of the wire feeding trolley is connected through a hinge, and the tail end of a cylinder body of the trolley action cylinder is connected with the floor of the working platform through a hinge, so that the wire feeding trolley can move back and forth on the floor of the working platform, and a large guide pipe is positioned to center a wire feeding hole in a steel ladle top cover; the base of wire feeder body sit on wire feeder platform truck through walking gyro wheel, the base of wire feeder body is connected through the hinge with the push rod head of wire feeder action cylinder, the cylinder body tail end of wire feeder action cylinder be connected through the hinge with the mesa of wire feeder platform truck to accomplish the front and back translation of wire feeder body on wire feeder platform truck, make the wire feeder body accomplish the wire feeding from the 90 return bends of area at last centering wire feeding large conduit. Although the wire feeding machine of the application has the advantages of small occupied space, high production efficiency, accurate positioning, reliable action and the like, the fed wire cannot completely enter molten steel, the manual operation time is still required, and the mechanical integration degree is not high; moreover, the patent does not provide an effective solution for how to reasonably put the wire materials into the molten steel effectively. It should be noted that the feeding of the bar stock and the feeding of the wire stock are also very different, the diameter and the mass of the bar stock are larger, and if the feeding operation is improper, the bar stock is easy to irregularly move in the air and splash into the molten steel, so that the stable operation of electroslag metallurgy is influenced; in addition, the feeding state and the feeding state of the bar stock are different, and how to effectively change the state of the bar stock for feeding is also the current difficult problem.

Therefore, in combination with the characteristics of the bar used in the field of electroslag metallurgy, for example, the metal bar such as aluminum bar used for reducing the oxygen content of the slag bath, there is a need to design a device capable of effectively feeding the bar.

In conclusion, the aluminum feeding machine disclosed by the invention is simple in structure, quite meets the requirements of an aluminum feeding process in an electroslag remelting process, and can realize the function of intelligent aluminum feeding. The specific operation of the aluminum casting machine is specifically described below with reference to fig. 1 to 8:

(1) firstly, the oxygen concentration sensor 123 is used for measuring the oxygen content in the molten steel and transmitting the measured oxygen content to the processor 801, the processor 801 processes the transmitted information and transmits the measured information to the aluminum feeder through the controller 802, and the aluminum feeder starts to operate automatically after determining the added aluminum amount; after the controller 802 receives the command, the controller 802 sends a next action command to the hydraulic station 803 and the encoder 530;

(2) the hydraulic oil in the hydraulic station 803 is supplied to the first hydraulic cylinder oil port i 311 of the first hydraulic cylinder 310 through an oil pipe, the hydraulic oil of the first hydraulic cylinder 310 returns through the first hydraulic cylinder oil port ii 312, and the first piston rod 313 pushes the material blocking member 320 to move towards the first stroke switch 330; when the material blocking member 320 passes through the first opening 201, one falling metal bar stock 100 is selected and pushed to the first discharge hole 341 to continue to fall, and at this time, the first protrusion 322 on the material blocking member 320 touches the first travel switch 330 to represent that the feeding unit has succeeded;

(3) after the controller 802 receives the signal of the first travel switch 330, the controller 802 sends a next action instruction, the hydraulic oil supplies oil to the first hydraulic cylinder oil port ii 312 of the first hydraulic cylinder 310, and at this time, the material blocking part 320 is reset; meanwhile, the hydraulic station 803 sends an instruction to enable the pushing hydraulic cylinder 420 to work, hydraulic oil in the hydraulic station 803 is supplied to a pushing hydraulic cylinder oil port II 422 of the pushing hydraulic cylinder 420 through an oil pipe, and the hydraulic oil of the pushing hydraulic cylinder 420 returns through a pushing hydraulic cylinder oil port I421, so that the pushing hydraulic cylinder 420 drives the pushing rod 410 to push the metal bar stock 100 to move to the cutting unit;

(4) when the encoder 530 reaches a value calculated in advance from the measured oxygen content, the pushing cylinder 420 stops operating; at this time, the controller 802 controls the hydraulic oil of the hydraulic station 803 to supply oil to the first cutting hydraulic cylinder oil port ii 542 of the first cutting hydraulic cylinder 540 and the second cutting hydraulic cylinder oil port ii 552 of the second cutting hydraulic cylinder 550 through oil pipes, the first cutting piston rod 543 and the second cutting piston rod 553 drive the cutting piece 560 to move upwards, and the first cutting piston 5431 contacts the cutting stroke switch 545 to indicate that the metal bar 100 is cut off;

(5) the cutting travel switch 545 transmits information to the controller 802, the controller 802 controls hydraulic oil to supply oil to a hydraulic port I631 of the translational hydraulic cylinder 630, and the translational piston rod 633 pushes the sliding block 620 together with the clamping chamber 600, the rotating mechanism 650 and the lifting mechanism 660 to move to the right; when the to-be-clamped bin 600 is far away from the cutting mechanism 500, the controller 802 controls the hydraulic oil in the hydraulic station 803 to supply oil to the second fluid inlet and outlet 6512, and the driving piston rod 652 moves leftwards to drive the driven gear 653 and the driven shaft 657 to rotate clockwise;

(6) the driven shaft 657 rotating clockwise drives the clamping chamber 600 to rotate clockwise at the same time, when the second protrusion 6523 on the driving piston rod 652 triggers the transmission travel switch 655, the clamping chamber 600 and the metal bar stock 100 clamped in the clamping chamber 600 rotate clockwise by 90 degrees, and the hydraulic station 803 stops supplying oil to the second fluid inlet/outlet 6512; then the transmission travel switch 655 transmits a signal that the rotation of the clamping bin 600 is completed to the controller 802, the controller 802 controls the hydraulic oil in the hydraulic station 803 to supply oil to the hydraulic cylinder oil port I6641 of the lifting hydraulic cylinder 661, and at the moment, the vertical clamping bin 600 drives the metal bar 100 to move upwards;

(7) when the clamping chamber 600 touches the lifting travel switch 710 upwards, the clamping chamber 600 is matched and sealed with the sealing cover, and the hydraulic station 803 stops supplying oil to a lifting hydraulic cylinder oil port I6641 of a lifting hydraulic cylinder 661; then the lifting travel switch 710 transmits a signal to the controller 802, and the controller 802 controls the argon gas station 804 to release high-pressure argon gas to the vent 730 to enable the metal bar 100 to be emitted out and enter molten steel through steel slag, so that the whole aluminum bar adding process is completed.

When the oxygen concentration sensor 123 measures the oxygen content in the molten steel to be greater than a set value, it represents that an aluminum rod needs to be added to the molten steel, and the operations (2) to (7) are repeated; when the bar travel switch does not touch the metal bar 100, the controller 802 sends an instruction indicating that no aluminum bar exists in the bar chute 430 or the aluminum bar is too short, and the feeding operation is completed by repeating the operation (2).
