Description

Technical Field

[0001] The invention relates to the technical field of high entropy alloy smelting, and more specifically, to a smelting device for preparing high entropy alloy materials. Background Art

[0002] High entropy alloys are considered to be one of the three major breakthroughs in alloying theory in recent decades. They are a new world of alloys that can be synthesized, analyzed and controlled. High entropy alloys have a combination of properties such as high hardness, high work hardening, high temperature softening resistance, high temperature oxidation resistance, corrosion resistance and high resistivity. In order to improve the performance of high entropy alloys, in the process of melting high entropy alloy materials, most of the time, multiple metal materials are put into the same melting furnace and melted by electric arc.

[0003] However, in the process of melting multiple metal elements in high entropy alloy materials in the existing melting device for preparing high entropy alloy materials, the metal material with a lower melting point melts faster, which causes the metal element with a higher melting point to precipitate at the bottom of the molten metal liquid due to gravity and be located at the bottom of the smelting furnace, while the molten metal liquid is located on the upper side. This not only increases the distance between the metal element with a higher melting point and the motor, but also causes a lower arc, which reduces the melting speed of the metal element with a higher melting point. At the same time, stratification occurs after the metal element with a higher melting point is melted, which reduces the performance of the high entropy alloy. At the same time, while waiting for the high melting point metal element to melt, the molten metal liquid on the upper side of the smelting furnace is close to the motor, which causes the metal liquid on the upper side of the smelting furnace to continue to be close to the electrode during the melting of the high melting point metal element, resulting in a stronger arc and a higher temperature on the molten metal liquid, resulting in the temperature of the molten metal liquid being too high, affecting the quality of the high entropy alloy.

After receiving the command, the servo motor 25 drives the screw 24 to rotate , the moving block 26 is driven to move through the restriction of the thread, and when the push block 33 is disengaged from the push rod 20, the blocking block 19 slides downward, so that the blocking block 19 slides into the discharge port 18, thereby achieving the blocking of the discharge port 18, wherein the upper surface of the weighing box 21 and the lower surface of the blocking block 19 are fixedly connected with mutually matching L-shaped rods 46, the horizontal sections of the two L-shaped rods 46 are parallel to each other, and the horizontal sections of the two L-shaped rods 46 are inclined and cooperate with each other, when the weighing box 21 moves to one side, the inclined surface of the horizontal section of the L-shaped rod 46 on the weighing box 21 pushes the horizontal section of the L-shaped rod 46 on the blocking block 19 downward, thereby making the L-shaped rod 46 drive the blocking block 19 to slide downward, making it convenient for the blocking block 19 to be inserted into the discharge port 18, thereby achieving the closure of the discharge port 18, wherein the horizontal section of the L-shaped rod 46 on the blocking block 19 is located on the upper side of the weighing box 21.

[0073] A sliding rod 27 is fixedly connected to the lower surface of the moving block 26, and a strip slide groove 28 is opened at the bottom of the loading box 14.

When the servo motor 25 drives the moving block 26 and the limit plate 30 to move horizontally through the lead screw 24, and the position of the limit plate 30 is relative to the position of the arc-shaped through hole 32, the electric telescopic rod 38 is turned on at this time, and the electric telescopic rod 38 pulls the push plate 39 upward, and the cover plate 34 is moved upward through the push plate 39. Pushing makes the lower end of the cover plate 34 upwardly detach from the bottom of the weighing box 21, so that the metal material weighed on the tray of the electronic scale 45 slides down through the opening on the side of the weighing box 21 into the arc-shaped material guide plate 22, and slides down through the inclined surface of the arc-shaped material guide plate 22 and the material guide tube 23 into the smelting furnace 1, so as to facilitate the smelting of the metal material, wherein the lower end of the cover plate 34 is fixedly connected with a connecting plate 41, and the connecting plate 41 cooperates with the push plate 39 to increase the contact area between the lower end surface of the cover plate 34 and the push plate 39, so as to facilitate the push plate 39 to push the cover plate 34 upward.

[0076] Working principle: The various metal materials in the high entropy alloy material to be smelted are placed in the storage chamber 17 respectively, and the distribution of the various metal materials in the high entropy alloy material is such that the height of the melting point decreases from the lower end to the upper end of the arc-shaped guide plate 22, so as to facilitate the smelting of the high melting point metal material first.

[0077] Then, the servo motor 25 and the wires on the electric telescopic rod 38 are electrically connected to the power storage device in the prior art, and the servo motor 25 is started. The output shaft on the servo motor 25 drives the lead screw 24 to rotate. Through the cooperation of the thread and the strip slide groove 28 and the sliding rod 27, the lead screw 24 drives the moving block 26 to move horizontally, so that the moving block 26 moves from the lower end of the arc guide plate 22 to the upper end, and drives the horizontal movement of the weighing box 21. When the push block 33 contacts the push rod 20, the push block 33 pushes the push rod 20 upward, and pushes the blocking block 19 upward through the push rod 20, so that the discharge port 18 is opened, and the high entropy alloy material in the storage chamber 17 slides downward through the discharge port 18 into the weighing box 21, and the falling high entropy alloy material is weighed by the electronic scale 45. When the weight value of the falling high entropy metal material reaches the preset threshold value, the electronic scale 45 sends a signal to the servo motor 25 issues a command, and the servo motor 25 drives the moving block 26, the weighing box 21, and the limit plate 30 to move horizontally through the lead screw 24. When the position of the limit plate 30 is relative to the position of the arc-shaped through hole 32, the servo motor 25 issues a command to the electric telescopic rod 38, and the electric telescopic rod 38 pulls the push plate 39 upward. When the upper surface of the push plate 39 contacts the lower surfaces of the cover plate 34 and the connecting plate 41, the push plate 39 pushes the cover plate 34 and the connecting plate 41 upward, so that the lower end of the cover plate 34 is upwardly separated from the bottom of the weighing box 21, thereby facilitating the weighing of the high entropy alloy material in the weighing box 21 to slide downward into the arc-shaped guide plate 22 through the opening on the side of the weighing box 21. Since the arc-shaped guide plate 22 is inclined, the high entropy alloy material in the arc-shaped guide plate 22 slides downward into the guide tube 23 through the inner arc wall of the arc-shaped guide plate 22, and slides downward into the smelting furnace 1 through the guide tube 23.

[0078] The staff connects the graphite electrode 2 to the power supply in the prior art, and the graphite electrode 2 is energized to perform arc melting on the high-entropy metal material in the smelting furnace 1. At this time, since the high-entropy alloy material weighed for the first time is a metal material that is difficult to melt, the staff turns on the drive motor 10. The output shaft of the drive motor 10 drives the rotating cylinder 3 to rotate through the meshing of the gear 11 and the outer gear ring 12. The rotating cylinder 3 drives the arc plate 4 and the arc salvage plate 5 to rotate. When the arc salvage plate 5 contacts the bottom of the smelting furnace 1, the rotation of the arc salvage plate 5 pushes the molten metal and particulate matter at the bottom of the smelting furnace 1 upward. When the molten metal contacts the filter holes 6 on the arc salvage plate 5, the molten metal flows to one side of the arc salvage plate 5 through the filter holes 6, and the particles The granular metal stays on the arc-shaped salvage plate 5. When the arc-shaped salvage plate 5 rotates to the side of the graphite electrode 2, the arc-shaped plate 4 is located at the lower side of the graphite electrode 2, and the granular metal material on the arc-shaped salvage plate 5 slides onto the arc-shaped plate 4 through the arc-shaped salvage plate 5. Since the arc-shaped plate 4 is close to the graphite electrode 2, the distance between the granular metal material and the graphite electrode 2 is reduced, so that the granular metal material is close to the graphite electrode 2, the intensity of the current on the metal material is increased, the temperature of the high-melting-point metal material is increased, and thus the melting speed of the high-melting-point metal material is increased. The molten metal liquid flows downward through the filter holes 6 on the arc-shaped plate 4 to the bottom of the smelting furnace 1, thereby preventing the metal liquid from being in a high-temperature state for a long time and affecting the metal liquid.

[0079] During the smelting process of the metal material, the servo motor 25 continues to drive the weighing box 21 to move, and weighs the high-melting-point metal material to the low-melting-point metal material in turn, thereby realizing the weighing ratio of the high-entropy alloy material, so that the ratio of each metal material in the high-entropy alloy material is equal, and after weighing the metal material, the weighed high-melting-point metal to the low-melting-point metal is discharged into the smelting furnace 1 through the arc guide plate 22 and the guide tube 23 in turn, thereby realizing the smelting of the high-entropy alloy material, and also improving the smelting speed of the high-entropy alloy material, and in the process of smelting each high-entropy metal material, the driving motor 10 drives the arc plate 4 and the arc salvage plate 5 to rotate. During the rotation of the arc salvage plate 5, not only can the granular metal material at the bottom of the smelting furnace 1 be salvaged, but also the molten metal liquid is stirred during the rotation of the arc salvage plate 5, so that multiple metal solutions are fused with each other, thereby facilitating the improvement of the performance of the high-entropy alloy material.

[0080] When the weighing box 21 has completed the weighing and proportioning of the multiple metals in the stored high-entropy alloy materials, the servo motor 25 drives the lead screw 24 to rotate in the opposite direction, thereby driving the moving block 26, the rotating block 29 and the weighing box 21 to rotate in the opposite direction, so that the positions of the moving block 26, the rotating block 29 and the weighing box 21 are restored, wherein the push rod 20 includes an upper push rod and a lower push rod, the lower end face of the lower push rod is inclined, and a hinge is fixedly connected to the side wall of the lower push rod, the upper end of the hinge is fixedly connected to the side wall of the upper push rod, and the inclined surface of the lower end of the lower push rod and the hinge are arranged opposite to the lower end of the arc guide plate 22, when the weighing box 21 is in the direction During movement, the push block 33 on the weighing box 21 pushes the lower push rod to one side, and at this time the lower end of the lower push rod rotates upward, thereby facilitating the weighing box 21 to move back. When the lead screw 24 drives the weighing box 21 to be pushed from the lower end of the arc-shaped guide plate 22 toward the upper end, and the push block 33 contacts the lower end surface of the lower push rod, at this time, the lower end of the lower push rod is blocked by the lower end of the upper push rod to the upper end surface of the lower push rod, thereby preventing the lower end of the lower push rod from rotating upward. Therefore, in the process of moving the push block 33, the push block 33 pushes the inclined surface of the lower push rod to push the lower push rod upward, thereby driving the blocking block 19 to move upward, thereby realizing the opening of the discharge port 18.

[0082] The following technical features are added on the basis of the first embodiment:

[0083] A smelting device for preparing high entropy alloy materials, wherein a rotating block 29 is rotatably connected to a moving block 26, and both ends of the rotating block 29 are fixedly connected to a limit plate 30, and the lower end of the limit plate 30 is slidably connected to the bottom of a charging box 14, and a connecting rod 43 is fixedly connected to the upper surface of the rotating block 29, and a weighing box 21 is fixedly connected to the upper end surface of the connecting rod 43, so that the weighing box 21 is fixedly connected to the rotating block 29, and a circular through hole is provided on the rotating block 29, and the rotating block 29 is rotatably connected to the moving block 26 through the circular through hole, wherein the bottom of the rotating block 29 is arc-shaped and has an arc-shaped hole, so that the rotating block 29 is on the moving block 26, and a torsion spring is provided on the rotating block 29, one end of the torsion spring is fixedly connected to the rotating block 29, and the other end of the torsion spring is fixedly connected to the moving block 26, and the rotating force of the torsion spring makes the arc-shaped end of the rotating block 29 be set downward, and the connecting rod 43 is vertical to the bottom of the charging box 14.

[0084] A strip limit groove 31 symmetrically arranged about the lead screw 24 is provided at the bottom of the loading box 14, and the lower end of the limit plate 30 is slidably connected in the strip limit groove 31. An arc-shaped through hole 32 is provided at the bottom of the strip limit groove 31. The two strip limit grooves 31 are connected through the arc-shaped through hole 32. The cooperation between the strip limit groove 31 and the limit plate 30 can prevent the limit plate 30 from rotating, thereby limiting the rotation of the rotating block 29, and the arc-shaped through hole 32 can facilitate the rotation of the limit plate 30 and the rotating block 29.

[0085] A pulley 35 is rotatably connected to the moving block 26, and a rope 36 is fixedly connected to the lower surface of the cover plate 34. One end of the rope 36 is passed through the pulley 35 and fixedly connected to the bottom of the weighing box 21. When the push plate 39 pushes the cover plate 34 upward, the cover plate 34 pulls the rope 36 upward, so that the rope 36 pulls the open end of the side of the weighing box 21 downward, and at the same time, the open end of the side of the weighing box 21 rotates downward, and drives the rotating block 29 to rotate, so that the limit plate 30 close to the arc guide plate 22 rotates downward to the arc through hole 32. At this time, the bottom of the weighing box 21 is inclined, so that the metal material that has been weighed in the weighing box 21 can slide down into the arc guide plate 22.

[0086] A baffle 37 is fixedly connected to the bottom of the loading box 14, and the side wall of the baffle 37 is in contact with the side wall of the rotating block 29. The side wall of the rotating block 29 is rectangular, and the lead screw 24 is located between the baffle 37 and the arc-shaped guide plate 22. In the process of the push plate 39 pushing the cover plate 34 upward, the baffle 37 blocks the side wall of the rotating block 29, thereby preventing the weighing box 21 from rotating in the opposite direction due to the thrust of the push plate 39.

[0087] An automatic control valve 40 is rotatably connected to the inner wall of the material guide pipe 23. The automatic control valve 40 is used to control the opening and closing of the material guide pipe 23. The material of the material guide pipe 23 and the automatic control valve 40 are both high-temperature resistant materials, thereby preventing damage to the material guide pipe 23 and the automatic control valve 40. When the weighed metal material slides into the material guide pipe 23 through the arc-shaped material guide plate 22, the automatic control valve 40 is opened at this time, and the metal material slides downward through the material guide pipe 23 into the smelting furnace 1.

[0088] Among them, cavities are opened in the arc-shaped guide plate 22 and the partition 16, and a smoke exhaust pipe 42 is fixedly connected to the bottom of the cavity. The smoke exhaust pipe 42 on the partition 16 passes through the inclined plate 15 and is fixedly connected to the upper end surface of the arc-shaped guide plate 22, and the lower end of the smoke exhaust pipe 42 on the partition 16 passes through the upper end surface of the arc-shaped guide plate 22 and is connected to the cavity. The smoke exhaust pipe 42 on the arc-shaped guide plate 22 is connected to the protection box 7, which is convenient for discharging the smoke in the protection box 7 into the cavity through the smoke exhaust pipe 42, so that the side wall of the cavity is heated by the heat contained in the smoke, so that the cavity transfers the temperature to the stored metal material, thereby realizing preheating treatment of the metal material, and further improving the melting rate of the high entropy alloy material.

[0089] Working principle: When the electronic scale 45 in the weighing box 21 has finished weighing the metal material, the servo motor 25 pushes the moving block 26, the rotating block 29 and the weighing box 21 toward the upper end of the arc-shaped guide plate 22 through the lead screw 24. When the position of the limit plate 30 is relative to the position of the arc-shaped through hole 32, the electric telescopic rod 38 pulls the push plate 39 upward, and pushes the cover plate 34 and the connecting plate 41 upward through the push plate 39. In the process of the cover plate 34 moving upward, one end of the rope 36 is pulled upward. The rope 36 is pulled to pull the port on the side of the weighing box 21 downward, so that the rotating block 29 drives the weighing box 21 to rotate downward. At this time, the bottom of the weighing box 21 is inclined, and the open end of the side of the weighing box 21 faces downward, which is convenient for the metal material weighed in the weighing box 21 to slide down the inclined surface of the bottom of the weighing box 21 into the arc-shaped guide plate 22, and then slide through the bottom of the arc-shaped guide plate 22 into the guide tube 23, thereby realizing the weighing and discharge smelting of the high entropy alloy material.

[0090] When the metal material weighed in the weighing box 21 slides down into the arc-shaped material guide plate 22, the electric telescopic rod 38 drives the push plate 39 to move downward, and the push plate 39 moves downward away from the cover plate 34 and the connecting plate 41. At this time, the rotating block 29 is driven to rotate by the rotational force of the torsion spring on the rotating block 29, so that the connecting rod 43 is vertical. At the same time, the position of the weighing box 21 is restored, and the cover plate 34 slides downward due to the action of gravity, so that the cover plate 34 covers the side wall of the weighing box 21.

[0091] When the weighed and proportioned metal material slides downward into the smelting furnace 1 through the guide pipe 23 for smelting, the smoke generated by the metal material during the smelting process enters the cavity in the arc-shaped guide plate 22 and the partition 16 through the smoke exhaust pipe 42, and the heat contained in the smoke is transferred through the side wall of the cavity to the metal material in contact with the partition 16 and the arc-shaped guide plate 22, thereby preheating the unmelted metal material, thereby increasing the heating rate of the metal material and further improving the smelting efficiency of the metal material, wherein the top of the partition 16 is fixedly connected with a discharge pipe, the lower end of the discharge pipe is connected to the cavity, the upper end of the discharge pipe passes through the top of the charging box 14 and extends to the upper side of the charging box 14, and the upper end of the discharge pipe can be connected to the smoke exhaust treatment pipe in the prior art, thereby reducing the pollution of the smoke and the heat contained in the smoke to the air.

[0092] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
