Description

Technical Field

[0001] The invention relates to the technical field of smelting furnaces, in particular to a temperature self-regulating smelting furnace for titanium alloy production. Background Art

[0002] The metal manufacturing industry has always been one of the pillar industries in China. Among them, smelting, cutting and grinding are the most commonly used processing methods in the metal manufacturing process. In the metal smelting process, the smelting furnace is the most commonly used metal smelting equipment. The smelting furnace melts the metal ingot into metal slurry through high temperature heating, and then injects the metal slurry into the corresponding mold to complete the metal processing;

[0003] Existing smelting furnaces usually use a bulk smelting method to melt metal raw materials, but the heating time required for bulk smelting is long and requires long heat conduction. In addition, during smelting, cold metal is usually directly placed into the smelting pot, further reducing the smelting efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a temperature self-regulating melting furnace for titanium alloy production to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A temperature self-regulating smelting furnace for titanium alloy production comprises a furnace body, a furnace cover is provided on the top of the furnace body, a preheating chamber and a smelting chamber are provided inside the furnace body, the preheating chamber is located above the smelting chamber, and a discharge chamber is provided at the bottom of the smelting chamber.

[0007] Preferably, the side of the preheating chamber close to the smelting chamber is hemispherical, and a plurality of spring plates are provided in the preheating chamber. A rotating shaft is provided at one end of the spring plate close to the preheating chamber, and a torsion spring is provided on the rotating shaft. The spring plate is rotatably connected to the inner wall of the preheating chamber through the rotating shaft.

[0008] When the smelting chamber is melting metal, the heat generated by the smelting is transported to the side close to the preheating chamber. The heat is conducted to the spring plate and then transferred to the surface of the metal stored in the preheating chamber through the spring plate. At this time, the preheating chamber plays a storage role. The metal is affected by the heat of the smelting and the temperature of the metal surface increases, thereby achieving the preheating effect and improving the efficiency of the smelting.

[0009] Preferably, the smelting chamber is composed of a plurality of vertical slots, the tops of the plurality of vertical slots converge and connect to the preheating chamber, a smelting pot is provided at the bottom of the vertical slots, the smelting pot is rotatably connected to the vertical slots, and the top area of ​​the vertical slots is larger than the bottom area of ​​the vertical slots;

[0010] By setting up several vertical slots and connecting all the vertical slots with the preheating chamber, the vertical slots can be divided into zones for metal smelting. By using a small amount and multiple smelting method, the smelting time is saved compared to overall smelting. The raw materials in the preheating chamber are transported to the vertical slots through the spring plate. Since the top area of ​​the vertical slots is larger than the bottom area of ​​the vertical slots, the raw materials fall into the smelting pot through the vertical slots.

[0011] Preferably, a heating coil is provided on the inner wall of the vertical groove, and the heating coil is arranged in a ring around a single vertical groove. A rotating motor is provided at the bottom of the vertical groove, and a driving shaft of the rotating motor is connected to the rotating shaft of the smelting pot.

[0012] After the raw materials fall into the melting pot, the controller controls the heating coil to start, and the heat generated by the heating coil is transferred to the raw materials. Different vertical slots can be set with different heating temperatures through the controller to adapt to different melting points of raw materials, thereby achieving the function of temperature self-adjustment. In addition, zoned heating is performed through the vertical slots. Compared with overall heating, the efficiency of heat conduction is improved, the time required to heat the raw materials to the melting point is reduced, and the efficiency of raw material smelting is improved. After the raw materials are smelted, the controller controls the rotation motor to start, and the driving shaft of the rotation motor drives the rotating shaft of the melting pot to rotate, and the melting pot rotates toward the discharge chamber.

[0013] Preferably, the discharge cavity is composed of a plurality of chutes and output chutes, the chutes are located at the bottom of the smelting pot, the chutes correspond to the smelting pots one-to-one, the ends of the chutes away from the smelting pot are connected to the output chutes, and a casting mold is provided at the bottom of the output chutes;

[0014] After the metal in the smelting pot is melted, the smelting pot rotates toward the side close to the chute. During the rotation of the smelting pot, the contained molten metal flows toward the chute, then flows through the chute to the output chute, and finally flows into the casting mold. By providing multiple chutes, the smelting pot can continuously pour out the molten metal liquid, and then the molten metal is output through different chutes, which improves the smelting efficiency. If the mold to be cast requires a large amount of molten metal, several smelting pots can rotate synchronously, so that the molten metal output from several chutes is collected in the output chute and output together.

[0015] Preferably, a plurality of toggle assemblies are provided on one side of the furnace cover close to the preheating chamber, and the toggle assemblies are composed of a transmission shaft, a moving ring, a pushing ring and two centrifugal balls.

[0016] Preferably, a No. 1 motor is provided inside the furnace cover, the drive shaft of the No. 1 motor is connected to the transmission shaft, a slide groove is provided on the shaft wall of the transmission shaft, a slider is provided on the inner wall of the movable ring and the push ring, and the movable ring and the push ring are rotatably connected to the transmission shaft through the slide groove and the slider.

[0017] Preferably, the movable ring is located above the push ring, a centrifugal ball is provided between the movable ring and the push ring, the centrifugal ball is hinged to the movable ring and the push ring respectively through a hinge rod, and a push head is provided on the side of the push ring away from the transmission shaft;

[0018] After the raw materials are input into the preheating chamber, the spring plate separates the vertical groove from the preheating chamber, so that the raw materials cannot be transported from the preheating chamber to the vertical groove. When the furnace cover covers the preheating chamber, the preheating chamber immediately forms a closed chamber. Then the controller controls the No. 1 motor to start, and the drive shaft of the No. 1 motor drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the centrifugal ball to rotate. The centrifugal ball rotates under the action of the transmission shaft. When the centrifugal ball rotates, it stirs the raw materials in the preheating chamber, making the raw materials in a tumbling state, thereby improving the uniform heating of the raw materials in the preheating chamber and improving the preheating effect of the raw materials.

[0019] When the molten metal in the smelting pot is poured and the next smelting is required, the controller controls the corresponding No. 1 motor to reduce the speed. Due to the reduction in speed, the centrifugal force generated by the drive shaft on the centrifugal ball is weakened, causing the centrifugal ball to move to the side close to the drive shaft. After the centrifugal ball shrinks inward, the hinged rod pushes the moving ring and the push ring to move to the opposite side, so that the push ring drives the push head to move to the side close to the spring plate, and the push head pushes the spring plate to move to the side close to the vertical groove, so that the preheating chamber is connected with the vertical groove, and then the raw materials in the preheating chamber fall into the smelting pot through the gap between the spring plate and the preheating chamber, thereby achieving the gap of small amounts and multiple times of adding raw materials. When the raw materials are added, the No. 1 motor is started again, and the push head moves away from the spring plate under the action of the push ring, and the spring plate is reset under the action of the torsion spring, so that the preheating chamber and the vertical groove are separated again.

[0020] Preferably, a gas delivery groove is provided at the top of the smelting chamber, a gas delivery pipe is provided between two adjacent vertical grooves, a gas storage chamber is provided in the center of several vertical grooves, one end of the gas delivery pipe is connected to the gas delivery groove, and the other end of the gas delivery pipe is connected to the gas storage chamber, a gas jet is provided on the side of the gas storage chamber close to the smelting pot, a valve is provided in the gas jet, an air pump is provided in the gas storage chamber, a pipeline of the air pump is respectively connected to the preheating chamber and the gas delivery pipe, and the ejection direction of the gas jet coincides with the tangent direction of the top of the smelting pot;

[0021] During the metal smelting process, a certain amount of steam is generated, flowing from the bottom of the vertical trough to the top. When the steam moves between the vertical trough and the spring plate, the controller activates the air pump, which draws gas through the gas trough and into the gas pipe. The gas is then delivered to the gas storage chamber via the gas pipe. Since the air pump is also connected to the preheating chamber via a pipe, the raw material is delivered to the preheating chamber. After the furnace cover closes the preheating chamber, the air pump extracts air from the preheating chamber, sealing the preheating chamber. As gas is continuously fed into the gas storage chamber, the pressure within the gas storage chamber increases. When one of the smelting pots pours molten metal into the chute, the axis of the smelting pot and the axis of the gas jet are parallel, meaning the jet's direction of discharge coincides with the tangential direction of the top of the smelting pot. The controller then controls the valve in the jet to open, and the gas in the gas storage chamber, under the action of the pressure, is ejected through the jet into the smelting pot. The gas then sprays tangentially into the smelting pot, cleaning and cooling the smelting pot.

[0022] Preferably, a disassembly plate is provided between two adjacent spring plates;

[0023] By setting up disassembly plates, when different alloys need to be melted separately, several disassembly plates can divide the preheating chamber into multiple small chambers. In addition, the vertical grooves correspond to the spring plates one by one, so that the melting furnace can simultaneously melt multiple alloys. Then, by distributing the output, the output of molten metal with different compositions can be achieved, thereby saving the number of melting furnaces. When it is necessary to melt one alloy, the disassembly plates are removed, and the preheating chamber forms an overall space, thereby accelerating the efficiency of metal melting.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up several vertical slots and connecting all the vertical slots with the preheating chamber, the vertical slots can be divided into zones for metal smelting. By using a small amount and multiple smelting method, the smelting time is saved compared to the overall smelting. By setting up a disassembly plate, when different alloys need to be smelted separately, the preheating chamber is divided into multiple small chambers by several disassembly plates. In addition, the vertical slots correspond to the spring plates one by one, so that the smelting furnace can carry out simultaneous smelting of multiple alloys. Then, by distributing the output, the output of metal liquids with different compositions is realized, thereby saving the number of smelting furnaces.

[0026] 2. Collect the steam generated by the preheating chamber and smelting. After the raw materials are smelted and output, the gas is discharged to the smelting pot through the air jet. The impact force of the gas compression is used to clean the smelting pot, which improves the utilization rate of the steam. At the same time, the steam is stored in the gas storage chamber, which has a certain insulation effect.

[0027] 3. When the smelting chamber is melting the metal, the heat generated by the smelting is transported to the side close to the preheating chamber. The heat is conducted to the spring plate and then transferred to the surface of the metal stored in the preheating chamber through the spring plate. At this time, the preheating chamber plays a storage role. The metal is affected by the heat of the smelting and the temperature of the metal surface increases, thereby achieving the preheating effect and further improving the efficiency of the smelting.

One end of the gas delivery pipe 27 is connected to the gas delivery groove 26, and the other end of the gas delivery pipe 27 is connected to the gas storage chamber 28. A gas injection port 29 is provided on the side of the gas storage chamber 28 close to the smelting pot 17. A valve is provided in the gas injection port 29, and an air pump is provided in the gas storage chamber 28.

The ejection direction of the gas injection port 29 coincides with the tangent direction of the top of the smelting pot 17.

[0047] Working principle of the present invention:

[0048] After the raw materials are input into the preheating chamber 12, the spring plate 15 separates the vertical groove 16 from the preheating chamber 12, so that the raw materials cannot be transported from the preheating chamber 12 to the vertical groove 16. When the furnace cover 11 covers the preheating chamber 12, the preheating chamber 12 immediately forms a closed chamber. Then the controller controls the No. 1 motor to start, and the drive shaft of the No. 1 motor drives the transmission shaft 21 to rotate. When the transmission shaft 21 rotates, it drives the centrifugal ball 24 to rotate. The centrifugal ball 24 rotates under the action of the transmission shaft 21. When the centrifugal ball 24 rotates, it stirs the raw materials in the preheating chamber 12, causing the raw materials to tumble, thereby improving the uniform heating of the raw materials in the preheating chamber 12.

[0049] When the molten metal in the smelting pot 17 is poured out and the next smelting is required, the controller controls the corresponding motor No. 1 to reduce its speed. Due to the reduced speed, the centrifugal force generated by the transmission shaft 21 weakens the force acting on the centrifugal ball 24, causing the centrifugal ball 24 to move closer to the transmission shaft 21. After the centrifugal ball 24 contracts inward, it pushes the moving ring 22 and the pushing ring 23 to move in opposite directions through the hinged rod, so that the pushing ring 23 drives the pusher head 25 to move closer to the spring plate 15. The pusher head 25 pushes the spring plate 15 to move closer to the vertical groove 16, so that the preheating chamber 12 is connected to the vertical groove 16. Then, the raw material in the preheating chamber 12 falls into the smelting pot 17 through the gap between the spring plate 15 and the preheating chamber 12, thereby achieving the goal of adding raw material in small amounts and multiple times. After the raw material addition is completed, the motor No. 1 is started again. The pusher head 25 is moved away from the spring plate 15 under the action of the pushing ring 23. The spring plate 15 is reset under the action of the torsion spring, so that the preheating chamber 12 and the vertical groove 16 are separated again.

[0050] After the raw materials fall into the smelting pot 17, the controller controls the heating coil to start, and the heat generated by the heating coil is transferred to the raw materials. Different vertical slots 16 can be set to different heating temperatures through the controller to adapt to different raw material melting points, thereby achieving the function of temperature self-adjustment. In addition, the vertical slots 16 are used for zoned heating. Compared with overall heating, this improves the efficiency of heat conduction, reduces the time required to heat the raw materials to the melting point, and improves the efficiency of raw material smelting. After the raw materials are smelted, the controller controls the rotation motor to start, and the drive shaft of the rotation motor drives the rotation shaft of the smelting pot 17 to rotate, and the smelting pot 17 rotates toward the discharge chamber 14.

[0051] After the metal in the smelting pot 17 is melted, the smelting pot 17 rotates toward the side close to the chute 18. During the rotation of the smelting pot 17, the contained molten metal flows toward the chute 18, then flows through the chute 18 to the output chute 19, and finally flows into the casting mold. By providing multiple chutes 18, the smelting pot 17 can continuously pour out the molten metal, and then the molten metal is output through different chutes 18, thereby improving the smelting efficiency. If the mold to be cast requires a large amount of molten metal, several smelting pots 17 can rotate synchronously, so that the molten metal outputted by several chutes 18 is collected in the output chute 19 and output together.

[0052] Since a certain amount of steam is generated during the metal smelting process, the steam flows from the bottom of the vertical groove 16 to the top of the vertical groove 16. When the steam moves to between the vertical groove 16 and the spring plate 15, the controller controls the air pump to start, and the air pump extracts the gas and delivers it to the gas delivery pipe 27 through the gas delivery groove 26. The gas is then delivered to the gas storage chamber 28 through the gas delivery pipe 27. Since the air pump is also connected to the preheating chamber 12 through the pipeline, after the raw materials are delivered to the preheating chamber 12 and the furnace cover 11 closes the preheating chamber 12, the air pump extracts the air in the preheating chamber 12, making the preheating chamber 12 in a sealed state. Gas is continuously fed into the gas storage chamber 28 to increase the gas pressure therein. When one of the smelting pots 17 pours the molten metal into the chute 18, the axis of the smelting pot 17 and the axis of the air jet 29 are parallel, i.e., the ejection direction of the air jet 29 coincides with the tangential direction of the top of the smelting pot 17. Subsequently, the controller controls the valve in the air jet 29 to open, and the gas in the gas storage chamber 28 is ejected into the smelting pot 17 through the air jet 29 under the action of the gas pressure. Furthermore, the gas is ejected tangentially toward the smelting pot 17, and the gas cleans and cools the smelting pot 17.

[0053] By providing the disassembly plates 30, when different alloys need to be melted separately, several disassembly plates 30 divide the preheating chamber 12 into multiple small chambers. In addition, the vertical grooves 16 correspond one-to-one with the spring plates 15, so that the smelting furnace can simultaneously melt multiple alloys. Then, by distributing the output, the output of molten metal with different compositions is achieved, thereby saving the number of smelting furnaces. When it is necessary to melt one alloy, the disassembly plates 30 are removed, and the preheating chamber 12 forms an integral space, thereby accelerating the efficiency of metal melting.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
