Description

Technical Field

[0001] The present invention relates to the field of sintering furnaces for preparing high-entropy alloys, and particularly relates to a sintering furnace and a preparation method for preparing a magnesium-containing lightweight high-entropy alloy. Background Art

[0002] An alloy generally refers to a substance formed by mixing two or more chemical substances with metallic properties. Alloys are usually obtained by melting the components into a homogeneous liquid and then condensing. There are various types of alloys, including high-entropy alloys. High-entropy alloys, abbreviated as HEA, are alloys formed by five or more equal or approximately equal amounts of metals. There are various types of high-entropy alloys, including magnesium-containing lightweight high-entropy alloys. Magnesium-containing lightweight high-entropy alloys usually require preparation operations and thus sintering furnaces will be used.

[0003] Sintering furnaces in the prior art usually include a furnace body, a furnace cover, electric heating elements, a vacuum pumping assembly, a circulating water discharge, etc. When sintering a magnesium-containing lightweight high-entropy alloy, the magnesium-containing lightweight high-entropy alloy is usually placed inside the furnace body, the furnace cover is closed, then the inside of the furnace body is evacuated, and at the same time the electric heating elements heat the inside of the furnace body to carry out the sintering operation. During and after the sintering process, the circulating water discharge cools the furnace body to prevent it from overheating itself, and at the same time, after the sintering is completed, the furnace body is cooled.

[0004] The circulating water discharge of the sintering furnace usually allows cooling water to enter the furnace body. After heat exchange, the cooling water is discharged. The discharged water with heat needs to enter the cooling equipment to recycle the cooling water. However, the heat carried out after heat exchange between the cooling water and the furnace body is usually not convenient for preheating the sintering of the magnesium-containing lightweight high-entropy alloy, thereby affecting the sintering efficiency of the magnesium-containing lightweight high-entropy alloy and increasing the comprehensive energy consumption.

[0072] The present invention also provides a preparation method for a sintering furnace for preparing a magnesium-containing lightweight high-entropy alloy, including the following specific use steps:

[0073] Step 1: Place the raw materials for preparing the magnesium-containing lightweight high-entropy alloy to be sintered inside the storage frame, put the raw materials for preparing the magnesium-containing lightweight high-entropy alloy to be sintered into the furnace cavity inside the furnace body, and use the control panel to close the furnace door to the inside of the furnace body. The furnace body performs electric energy sintering on the raw materials for preparing the magnesium-containing lightweight high-entropy alloy inside the furnace cavity. During the sintering process, the fixed pipe is connected to the pipe body of an external water pump, and water is introduced into the water storage frame. The first liquid level sensor monitors the liquid level of the water added to the water storage frame. After reaching the set liquid level height h, a stop signal is generated, and the controller receives the stop signal and stops the operation of the external water pump;

[0074] Step 2: The external cooling water enters the interior of the furnace body through the water inlet pipe, flows through the interlayer of the furnace body, and is discharged from the interior of the outlet pipe. The cooling water exchanges heat with the heat on the furnace body. The cooled cooling water enters the interior of the arc-shaped cylinder through the interior of the connecting pipe, and then flows through the interiors of multiple arc-shaped cylinders and connecting cylinders and is discharged from the discharge pipe. When the cooled cooling water flows, it transfers heat to the arc-shaped cylinder and the connecting cylinder. Furthermore, the heat on the arc-shaped cylinder and the connecting cylinder heats the water inside the water storage frame. The temperature sensor is used to monitor the temperature of the water inside the water storage frame in real time;

[0075] Step 3: If the temperature sensor monitors that the temperature of the water inside the water storage frame reaches the set temperature, it sends a start signal. After receiving the start signal, the controller starts the pump body to run. At the same time, a timer is used for timing. After reaching time t, an inlet water signal is sent to the controller. After receiving the inlet water signal, the controller starts the external water pump to work to add water to the interior of the water storage frame through the fixed pipe. The pump body pumps out the heated water inside the water storage frame through the extraction pipe, and then introduces it into the interior of the preheating box through the access pipe and is discharged through the diversion pipe. Multiple diversion pipes evenly pour the heated water on the heat exchange rack. The heat exchange rack performs a heat exchange operation on the heated water, thereby heating the internal material storage frame to preheat the raw materials for preparing the magnesium-containing light high-entropy alloy inside the material storage frame. Moreover, the heated water is connected inside the preheating box and flows inside the through groove. The second liquid level sensor is used to monitor the liquid level height inside the preheating box. If it reaches the set liquid level height h, a drainage signal is sent to the control. After receiving the drainage signal, the controller opens the valve body on the support pipe to discharge the heated water inside the preheating box for other uses. The temperature sensor is used to monitor the temperature inside the heat exchange rack. At the same time, a timer is used to time the preheating time of the raw materials for the magnesium-containing light high-entropy alloy to be sintered and prepared inside the material storage frame. If the set temperature is reached and it lasts for time t, an alarm signal is sent to the controller. After receiving the alarm signal, the controller turns on the alarm to give an alarm, opens the box door, pulls out the material storage frame, and takes out the preheated raw materials for the magnesium-containing light high-entropy alloy to be sintered, and transfers them to the furnace cavity inside the furnace body for electric energy sintering preparation.

[0076] The technical effects and advantages of the present invention:

[0077] (1) With the cooperation of the auxiliary box, the cover plate, the water storage frame, the fixed pipe, the arc-shaped cylinder, the connecting cylinder, the discharge pipe and the preheating mechanism, after the cooling water exchanges heat with the furnace body, it enters the interiors of the arc-shaped cylinder and the connecting cylinder to heat the water inside the water storage frame. The heated water is used to preheat the raw materials for the magnesium-containing light high-entropy alloy to be prepared. This is beneficial to shortening the sintering preparation cycle of the magnesium-containing light high-entropy alloy, improving the sintering efficiency, and at the same time facilitating the realization of energy self-circulation and reducing the comprehensive energy consumption;

[0078] (2) The present invention utilizes the cooperative setting of a preheating box, an embedding frame, a heat exchange rack, a storage frame, a through groove, a pump body, an access pipe, a diversion pipe, and a support pipe. The heat exchange rack stores the magnesium-containing lightweight high-entropy alloy raw materials to be sintered. The access pipe allows the heated water to be added into the interior of the preheating box. The diversion pipe directly pours the heated water onto the heat exchange rack to heat the heat exchange rack. By the heated water flowing inside the through groove, the heating efficiency of the heat exchange rack is improved. The storage frame stores and takes out the magnesium-containing lightweight high-entropy alloy raw materials to be sintered, which is conducive to preheating the magnesium-containing lightweight high-entropy alloy raw materials to be sintered, facilitating the full transfer of the heat of the heated water to the heat exchange rack, improving the preheating efficiency, and at the same time facilitating other uses of the hot water inside the preheating box;

[0079] (3) The present invention utilizes the cooperative setting of a first frame body, an intermediate body, a second frame body, an assembly body, an extension body, an assembly plate, and a guide plate. The first frame body and the second frame body are respectively connected to the preheating box and the auxiliary box. The intermediate body connects the first frame body and the second frame body in series. The assembly plate positions the installation of the intermediate body, which is conducive to connecting the auxiliary mechanism and the connecting mechanism in series for simultaneous installation and disassembly;

[0080] (4) The present invention utilizes the cooperative setting of a blocking plate, a sliding rod, a moving ring, a limiting ring, and a first spring. The sliding rod connects the blocking plate to the extension body. The elastic force of the first spring pushes the moving ring to move to elastically support the blocking plate. The blocking plate limits and blocks the front of the box door to close the box door, which is conducive to limiting and blocking the box door to prevent the box door from being opened randomly;

[0081] (5) The present invention utilizes the cooperative setting of a bearing frame, a moving frame, a locking column, a supporting frame, an auxiliary rod, and a second spring. The moving frame drives the locking column to move. The locking column limits the relative positions of the supporting frame and the assembly frame. The elastic force of the second spring pushes the moving frame to move, which is conducive to limiting the relative position between the intermediate body and the assembly plate and facilitating the installation and disassembly of the connecting mechanism.

[0105] Usage method of the present invention:

[0106] Place the raw materials for preparing the magnesium-containing light high-entropy alloy to be sintered inside the storage frame 34, put the raw materials for preparing the magnesium-containing light high-entropy alloy to be sintered into the furnace cavity 14 inside the furnace body 11, and use the control panel 13 to close the furnace door 12 to the inside of the furnace body 11. The furnace body 11 performs electric sintering on the raw materials for preparing the magnesium-containing light high-entropy alloy inside the furnace cavity 14. During the sintering process, the fixed pipe 24 is connected to the pipe body of an external water pump, and water is introduced into the water storage frame 23. Use the first liquid level sensor to monitor the liquid level of the water added to the water storage frame 23. After reaching the set liquid level height h, a stop signal is generated. The controller receives the stop signal and stops the operation of the external water pump;

[0107] External cooling water enters the inside of the furnace body 11 through the water inlet pipe 17, flows through the interlayer of the furnace body 11 and is discharged from the inside of the water outlet pipe 18. The cooling water exchanges heat for the heat on the furnace body 11. The heat-exchanged cooling water enters the inside of the arc-shaped cylinder 25 through the inside of the connecting pipe 27, and then flows through the inside of a plurality of arc-shaped cylinders 25 and the connecting cylinder 26 and is discharged from the discharge pipe 28. When the heat-exchanged cooling water flows, heat is transferred to the arc-shaped cylinder 25 and the connecting cylinder 26. Furthermore, the heat on the arc-shaped cylinder 25 and the connecting cylinder 26 heats the water inside the water storage frame 23. Use the temperature sensor to monitor the temperature of the water inside the water storage frame 23 in real time;

[0108] If the temperature sensor monitors that the temperature of the water inside the water storage frame 23 reaches the set temperature, it sends a start signal. After receiving the start signal, the controller turns on the pump body 36 to operate. At the same time, a timer is used for timing. After reaching time t, an inlet water signal is sent to the controller. After receiving the inlet water signal, the controller starts the external water pump to work, so as to add water to the inside of the water storage frame 23 through the fixed pipe 24. The pump body 36 pumps out the heated water inside the water storage frame 23 through the lead-out pipe 29, and then introduces it into the inside of the preheating box 31 through the access pipe 37, and discharges it through the diversion pipe 38. The multiple diversion pipes 38 evenly pour the heated water on the heat exchange frame 33. The heat exchange frame 33 performs a heat exchange operation on the heated water, thereby heating the internal material storage frame 34 to preheat the raw materials for preparing the magnesium-containing light high-entropy alloy inside the material storage frame 34. And the heated water is connected inside the preheating box 31 and flows inside the through groove 35. The second liquid level sensor is used to monitor the liquid level height inside the preheating box 31. If it reaches the set liquid level height h, a drainage signal is sent to the control. After receiving the drainage signal, the controller opens the valve body on the support pipe 39 to discharge the heated water inside the preheating box 31 for other uses. The temperature sensor is used to monitor the temperature inside the heat exchange frame 33. At the same time, the timer is used to time the preheating time of the raw materials of the magnesium-containing light high-entropy alloy to be sintered and prepared inside the material storage frame 34. If it reaches the set temperature and lasts for time t, an alarm signal is sent to the controller. After receiving the alarm signal, the controller turns on the alarm to give an alarm, opens the box door 312, and pulls out the material storage frame 34 to take out the preheated raw materials of the magnesium-containing light high-entropy alloy to be sintered, and transfers them to the inside of the furnace cavity 14 on the furnace body 11 for electric energy sintering preparation.
