Description

Technical Field

[0001] The invention relates to the technical field of suspension smelting, in particular to a suspension smelting positioning tool. Background Art

[0002] Levitation melting (e.g., electromagnetic levitation melting) is a melting technique that uses electromagnetic force to suspend a metal or alloy melt above a crucible. It has the advantages of no crucible contamination, uniform composition, and high melting temperatures. The melt does not come into contact with the crucible, preventing chemical reactions or physical contamination, and thus preventing contamination of the melt by the crucible material.

[0003] In existing suspension smelting operations, the molten material is extremely hot after suspension smelting. If it falls directly into a cold crucible, the large temperature difference may cause the crucible to crack or the molten material to splash, easily affecting the efficiency of the metal smelting. Furthermore, if the molten material in the crucible is cooled only by blowing nitrogen during the cooling process, the cooling rate is slow and the nitrogen consumption is large, resulting in nitrogen waste. Summary of the Invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that the temperature of the molten material after suspension melting is extremely high, and if it falls directly into a cold crucible, the temperature difference is too large, which may cause the crucible to break or the molten material to splash, which may easily affect the metal melting efficiency;

[0006] (2) How to solve the problem that in the process of cooling the melt, if it is cooled only by blowing nitrogen, not only the cooling speed is slow, but also the amount of nitrogen consumed is large, resulting in nitrogen waste.

[0007] The objectives of the present invention can be achieved by the following technical solutions: a suspension smelting positioning tool, comprising a base and a sealing cover fixedly mounted on the top of the base, wherein the suspension smelting tool is fixedly mounted on one side of the top of the base, the suspension smelting tool is a prior art tool, and a water cooling mechanism for cooling the crucible is provided below the suspension smelting tool, and a preheating mechanism for heating the crucible is provided on one side of the water cooling mechanism;

[0008] The preheating mechanism includes a square rod movably inserted on the top of the sealing cover. The square rod is arranged longitudinally, and an electric heating rod is fixedly installed on the bottom end of the square rod. A guide frame for guiding the square rod is also fixedly installed on the inner wall of the sealing cover.

[0009] A further technical improvement of the present invention is that a cylinder is fixedly inserted on the outer wall of the sealing cover, the cylinder is arranged horizontally, and the protruding end of the cylinder is fixedly connected to a fixing pin, and an L-shaped rod is rotatably arranged on the inner wall of the sealing cover on one side of the square rod, and the bottom of the L-shaped rod corresponds to the position of the fixing pin.

[0010] A further technical improvement of the present invention is that a push plate is fixedly installed on the top of the square rod, a thrust spring is elastically arranged between the push plate and the top wall of the sealing cover, and the middle part of the square rod is movably connected to the top end of the L-shaped rod through a shift rod.

[0011] A further technical improvement of the present invention is that: a blowing pipe is fixedly inserted on the outer side wall of the sealing cover on one side of the square rod, and the output end of the blowing pipe is arranged toward the electric heating rod; by controlling the extended end of the cylinder to shrink from the longest to the shortest, the crucible is driven to move to the preheating position, and the L-shaped rod is driven to rotate by the fixed pin, so that the L-shaped rod cooperates with the shifting rod to drive the square rod downward, so that the electric heating rod is extended into the crucible, and the electric heating rod is turned on to preheat the inner wall of the crucible, so as to avoid the molten material after subsequent suspension smelting directly falling into the cold crucible, and to prevent the crucible from breaking or the molten material from splashing due to excessive temperature difference, thereby ensuring the efficiency of metal smelting.

[0012] A further technical improvement of the present invention is that the water cooling mechanism includes a support seat slidably connected to the top surface of the base, a slot for positioning the crucible is provided on one side of the top of the support seat, and a baffle is fixedly installed on the other side of the top of the support seat, and the baffle is fixedly connected to the protruding end of the cylinder.

[0013] A further technical improvement of the present invention is that two through-holes are provided at the bottom of the support seat, sealing rings are fixedly provided on the inner walls of the bottom ends of the two through-holes, and the top ends of the two through-holes are communicated with the card slot.

[0014] A further technical improvement of the present invention is that a water tank is fixedly provided at the bottom of the base, a water pump is fixedly installed on the front of the water tank, the input end of the water pump is connected to the bottom of the water tank, and the output end of the water pump is connected to the water inlet pipe, and the bottom of the water tank is also connected to the return pipe.

[0015] A further technical improvement of the present invention is that: the output end of the water inlet pipe and the input end of the return pipe are fixedly passed through the base, and the positions of the output end of the water inlet pipe and the input end of the return pipe respectively correspond to the bottom end positions of the two perforations; after the nitrogen flow passes through the electric heating rod for heating, the hot nitrogen obtained performs preliminary blowing and heat dissipation on the melt; when the temperature of the melt in the crucible drops to a threshold value, the electric heating rod is turned off, so that the room temperature nitrogen performs a secondary blowing and heat dissipation on the melt; after the temperature of the melt in the crucible drops below degrees Celsius, the air supply tooling is turned off, and the protruding end of the cylinder is controlled to extend to half its length, the output end of the water inlet pipe and the input end of the return pipe are respectively connected to the bottom ends of the two perforations, and the water pump is turned on, so that clean water is injected into the card slot through the water inlet pipe to water-cool the crucible, and then returns to the water storage tank along the return pipe. In the above manner, the melt in the crucible is cooled in a step-by-step manner, which not only speeds up the cooling speed but also prevents the waste of nitrogen.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present invention is in use, the extended end of the cylinder is controlled to shrink from the longest to the shortest, thereby driving the crucible to move to the preheating station, and the L-shaped rod is driven to rotate by the fixing pin, so that the L-shaped rod cooperates with the shifting rod to drive the square rod to move downward, so that the electric heating rod is extended into the crucible, and the electric heating rod is turned on to preheat the inner wall of the crucible, thereby preventing the molten material from directly falling into the cold crucible after subsequent suspension smelting, preventing the crucible from breaking or the molten material from splashing due to excessive temperature difference, and ensuring the efficiency of metal smelting.

[0018] When the present invention is in use, after the nitrogen flow passes through the electric heating rod for heating, the hot nitrogen obtained is used to blow the melt for preliminary heat dissipation. When the temperature of the melt in the crucible drops to a threshold value, the electric heating rod is turned off, so that the room temperature nitrogen is used to blow the melt for a second time to dissipate heat. After the temperature of the melt in the crucible drops below degrees Celsius, the air supply tooling is turned off, and the extended end of the cylinder is controlled to extend to half its length. The output end of the water inlet pipe and the input end of the return pipe are respectively connected to the bottom ends of the two perforations, and the water pump is turned on to allow clean water to be injected into the card slot through the water inlet pipe to water-cool the crucible and then return to the water storage tank along the return pipe. In the above manner, the melt in the crucible is cooled in a step-by-step manner, which not only speeds up the cooling speed but also prevents the waste of nitrogen.

[0037] See also Figure 2 and Figure 3 As shown, a gas supply fixture 1 for providing nitrogen is fixedly provided on the outer wall of the sealing cover 6 . The gas supply fixture 1 is of prior art, and the output end of the gas supply fixture 1 is connected to the input end of the blowing pipe 902 .

[0038] See also Figure 2 As shown, the side wall of the sealing cover 6 away from the air supply tool 1 is connected to an exhaust pipe 10, an exhaust valve is fixedly installed in the middle of the exhaust pipe 10, and a sealing door 5 is hinged on the front of the sealing cover 6.

[0039] Working principle: When the present invention is used, first, before the suspension smelting of metal, the gas supply tool 1 and the exhaust valve are opened, so that the nitrogen gas in the sealing cover 6 is input from the gas supply tool 1, and the air in the sealing cover 6 is squeezed out from the exhaust pipe 10, thereby reducing the oxygen content in the sealing cover 6 and avoiding interference with the subsequent suspension smelting of metal; in this process, the extended end of the cylinder 2 is controlled to shrink from the longest to the shortest, driving the crucible to move to the preheating station, and the L-shaped rod 903 is driven to rotate by the fixing pin 907, so that the L-shaped rod 903 The lever 905 is coordinated with the square rod 906 to move downward, so that the electric heating rod 908 extends into the crucible, and the electric heating rod 908 is turned on to preheat the inner wall of the crucible, so as to prevent the molten material after subsequent suspension smelting from directly falling into the cold crucible, and to prevent the crucible from breaking or the molten material from splashing due to excessive temperature difference, thereby ensuring the efficiency of metal smelting; by opening the sealing door 5, the extended end of the cylinder 2 is controlled to be reset to the longest, and then the metal is put into the suspension smelting tooling 8 in the open state through the external feeding equipment, and the sealing door 5 is closed, and the suspension smelting tooling is used to heat the metal. 8. The metal is melted, and the resulting molten material falls into the crucible. At this time, the nitrogen gas flow blown out from the output end of the blowing pipe 902 is heated by the electric heating rod 908, and the hot nitrogen obtained is used to initially blow and dissipate heat to the molten material in the crucible. When the temperature of the molten material in the crucible drops to a threshold value, the electric heating rod 908 is turned off, so that the nitrogen gas at room temperature blows and dissipates heat to the molten material in the crucible for the second time. After the temperature of the molten material in the crucible drops below 500 degrees Celsius, the gas supply tool 1 is turned off in time, and the extended end of the cylinder 2 is extended to half its length by controlling the air supply tool 1. At this time, the fixing pin 907 is not in contact with the L-shaped rod 903, the output end of the water inlet pipe 701 and the input end of the water return pipe 703 are connected to the bottom ends of the two through holes 705 respectively, and the water pump 702 is turned on, so that the clean water in the water storage tank 3 is injected into the card slot 707 through the water inlet pipe 701, and the crucible inside is cooled by water. Then, the water is returned to the water storage tank 3 along the water return pipe 703. In this way, the melt in the crucible is cooled in a step-by-step manner, avoiding cooling by blowing nitrogen alone, which not only speeds up the cooling speed but also prevents the waste of nitrogen.
