Description

Technical Field

[0001] This utility model relates to the field of aluminum-magnesium alloy production technology, specifically a continuous annealing furnace for aluminum-magnesium alloy production. Background Technology

[0002] Aluminum-magnesium alloy is an alloy material composed of aluminum as the main component, with appropriate amounts of magnesium and other trace elements added. Aluminum-magnesium alloy has advantages such as low density and high strength, good corrosion resistance, excellent thermal and electrical conductivity, and good processing performance. It is widely used in aerospace, automotive, electronics and electrical appliances and rail transportation fields.

[0003] Aluminum-magnesium alloys require heat treatment during production, and annealing is a key step in the heat treatment process. Currently, the annealing furnaces used for annealing aluminum-magnesium alloys generally involve first placing the aluminum-magnesium alloy into the furnace, then closing the furnace gate, heating the aluminum-magnesium alloy in the furnace for a sufficient time, and then allowing it to cool naturally.

[0004] However, most annealing furnaces currently used for annealing aluminum-magnesium alloys currently only have one gate. The aluminum-magnesium alloy is placed into and removed from the furnace at the same gate. Therefore, the gate cannot be opened while the furnace is heating, otherwise it will cause instability in the furnace and affect the normal operation of the annealing process. Furthermore, the furnace must be stopped when handling aluminum-magnesium alloys, which reduces the efficiency of the annealing process. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, firstly, cylinder one drives the door panel of the port compartment at the inlet end to rise, while cylinder two at the inlet end drives the outer sprocket to rotate. The outer sprocket synchronously drives transmission sprocket one and transmission sprocket two to rotate, thereby causing the take-up and unwinding rollers to wind up the wire rope and drive the partition plate to rise. Then, batches of aluminum-magnesium alloys are placed one by one onto the auxiliary roller of the port compartment at the inlet end, and the aluminum-magnesium alloys are pushed to move in a straight line into the transmission roller inside the main compartment. Then, the partition plate is lowered, thereby making the interior of the main compartment a sealed space. High-temperature steam enters the main pipe through the inlet pipe and diffuses the high temperature into the main compartment. At the same time, multiple motors drive multiple fans to operate. The airflow generated by the multiple fans can blow the high temperature emitted from the main pipe, increasing the flow speed of the high-temperature gas. This can both increase the rate of temperature rise inside the main compartment and keep the temperature in various positions inside the main compartment balanced, ensuring the annealing effect of the aluminum-magnesium alloy. The partition plates at both ends of the main compartment prevent the high-temperature air from dissipating to the outside of the main compartment.

[0020] 2. In this utility model, when the batch of aluminum-magnesium alloy in the main chamber is heated simultaneously, the door panels and partitions at both ends of the main chamber are all raised. Then, the second motor drives multiple transmission rollers to rotate. The multiple transmission rollers can move the aluminum-magnesium alloy towards the port chamber at the outlet end, so that the aluminum-magnesium alloy moves to the auxiliary roller at the outlet end. At the same time, the next batch of aluminum-magnesium alloy that needs to be heated moves to the auxiliary roller at the inlet end and enters the main chamber. Thus, the placement and removal of aluminum-magnesium alloy can be carried out simultaneously, increasing the efficiency of the aluminum-magnesium alloy annealing process.

[0021] 3. In this invention, when a batch of aluminum-magnesium alloys is not simultaneously placed into the main chamber, the aluminum-magnesium alloys near the outlet end are heated first because they entered the main chamber earlier. At this time, the door and partition plates at the outlet end are raised, and then the transmission rollers move the heated aluminum-magnesium alloys onto the auxiliary rollers. Then, the door and partition plates at the outlet end are lowered and closed. After the door and partition plates at the outlet end are lowered and closed, the door and partition plates at the inlet end are raised again to allow a new batch of aluminum-magnesium alloys to enter the main chamber. This achieves uninterrupted annealing of aluminum-magnesium alloys, increases the efficiency of the annealing process, and because only one end of the door and partition plates is opened at a time, the rate at which high-temperature gas escapes from the main chamber is minimized, thereby reducing the temperature fluctuation range in the main chamber and further increasing the efficiency and effectiveness of the annealing process.

[0039] The lower inner side of the port compartment 11 is uniformly provided with a plurality of auxiliary rollers 12, and both ends of the plurality of auxiliary rollers 12 are rotatably connected to the port compartment 11 through bearings 13; a bracket 16 is welded to the top of the port compartment 11 on the side away from the partition compartment 31; both ends of the top of the door panel 15 are integrally provided with sliders 17. Both sliders 17 are slidably connected to the bracket 16; a connecting frame 18 is welded to the middle of the top of the bracket 16, and the connecting frame 18 is fixedly connected to the lower end of the cylinder 19, and the telescopic rod of the cylinder 19 is fixedly connected to the middle of the top of the door panel 15;

Both the first transmission sprocket 34 and the second transmission sprocket 35 are rotatably connected to the upper inner side of the partition compartment 31.

[0041] By adopting the above technical solution, firstly, cylinder 19 drives the door panel 15 of the port compartment 11 at the inlet end to rise, while cylinder 51 at the inlet end drives the outer sprocket 54 to rotate. The outer sprocket 54 synchronously drives the transmission sprocket 34 and the transmission sprocket 35 to rotate, thereby causing the take-up and untake-down roller 32 to take up the wire rope 36 and drive the partition plate 37 to rise. Then, the batch of aluminum-magnesium alloys are placed one by one on the auxiliary roller 12 of the port compartment 11 at the inlet end, and the aluminum-magnesium alloys are pushed to move in a straight line into the transmission roller 63 in the main compartment 2. Then, the partition plate 37 is lowered, thereby allowing the main compartment 2 to move in a straight line into the main compartment 2. The interior of chamber 2 becomes a sealed space; high-temperature steam enters the main pipe 71 through the inlet pipe 72 and diffuses the high temperature into the main chamber 2. At the same time, multiple motors 41 drive multiple fans 46 to operate. The airflow generated by the multiple fans 46 can blow away the high temperature emitted from the main pipe 71 and increase the flow speed of the high-temperature gas. This can increase the rate of temperature rise in the main chamber 2 and keep the temperature in various positions in the main chamber 2 balanced, ensuring the annealing effect of the aluminum-magnesium alloy. The partition plates 37 at both ends of the main chamber 2 serve to prevent the high-temperature air from dissipating to the outside of the main chamber 2.

[0042] In this embodiment, the drive assembly 5 includes a second cylinder 51, which is located outside the partition chamber 31; the bottom of the second cylinder 51 is rotatably connected to a connector 52, one side of which is welded to the lower outer side of the partition chamber 31; the telescopic rod of the second cylinder 51 is fixedly connected to a chain belt 53, and the end of the chain belt 53 away from the second cylinder 51 is fixedly connected to an outer sprocket 54 and the chain belt 53 meshes with the outer sprocket 54; a connecting shaft is provided in the middle of the outer sprocket 54, and the end of the connecting shaft away from the outer sprocket 54 is fixedly connected to the middle of a first transmission sprocket 34;

[0043] The fan assembly 4 includes a motor 41, a fan 46 is provided on one side of the motor 41, and the upper end of the fan 46 and the bottom of the motor 41 are fixedly connected to the top of the main chamber 2. The top of the main chamber 2 is provided with a circular through slot for the fan 46 to pass through. A driven pulley 44 is fixedly connected to the top of the main shaft in the middle of the fan 46, and a driving pulley 43 is fixedly connected to the output shaft of the motor 41. The driving pulley 43 is connected to the driven pulley 44 through a belt 42. A housing 45 is provided on the outer side of the upper end of the main shaft of the fan 46, and the main shaft is rotatably connected to the top of the housing 45.

[0044] The heating component 7 includes a main pipe 71 located below the fan 46 and is curved. The two ends of the main pipe 71 are respectively provided with an inlet pipe 72 and an outlet pipe 73, and the ends of the inlet pipe 72 and the outlet pipe 73 away from the main pipe 71 are located above the main chamber 2.

[0045] By adopting the above technical solution, when the batch of aluminum-magnesium alloy in the main chamber 2 is heated simultaneously, the door panels 15 and partition plates 37 at both ends of the main chamber 2 are all raised. Then, the motor 61 drives multiple transmission rollers 63 to rotate. The multiple transmission rollers 63 can move the aluminum-magnesium alloy towards the port chamber 11 at the outlet end, so that the aluminum-magnesium alloy moves to the auxiliary roller 12 at the outlet end. At the same time, the next batch of aluminum-magnesium alloy that needs to be heated moves to the auxiliary roller 12 at the inlet end and enters the main chamber 2. Thus, the placement and removal of aluminum-magnesium alloy can be carried out simultaneously, increasing the efficiency of the aluminum-magnesium alloy annealing process.

[0046] In this embodiment, the transmission structure 6 includes multiple transmission rollers 63, which are arranged in a straight line and are all located below the main pipe 71; both ends of the multiple transmission rollers 63 are rotatably connected to the lower inner side of the main chamber 2.

[0047] One end of each of the plurality of drive rollers 63 is fixedly connected to a drive sprocket 67, and two adjacent drive sprockets 67 are connected by a chain 68; one end of the drive roller 63 located at the end of the plurality of drive rollers 63 is also fixedly connected to a driven sprocket 65.

[0048] The driven sprocket 65 is located outside the main compartment 2. The upper end of the driven sprocket 65 is provided with a driving sprocket 64, and the driving sprocket 64 is connected to the driven sprocket 65 through a chain 66. The middle of the driving sprocket 64 is fixedly connected to the output shaft of the motor 61, and the bottom of the motor 61 is fixedly connected to the placement platform 62.

[0049] By adopting the above technical solution, when a batch of aluminum-magnesium alloys is not placed into the main chamber 2 simultaneously, the aluminum-magnesium alloys near the outlet end are heated first because they enter the main chamber 2 earlier. At this time, the door plate 15 and partition plate 37 at the outlet end are raised, and then the transmission roller 63 moves the heated aluminum-magnesium alloys onto the auxiliary roller 12. Then, the door plate 15 and partition plate 37 at the outlet end are lowered and closed. After the door plate 15 and partition plate 37 at the outlet end are lowered and closed, the door plate 15 and partition plate 37 at the inlet end are raised again to allow a new batch of aluminum-magnesium alloys to enter the main chamber 2. This achieves uninterrupted annealing of aluminum-magnesium alloys, increases the efficiency of annealing, and because only one end of the door plate 15 and partition plate 37 is opened at a time, the rate at which high-temperature gas escapes from the main chamber 2 can be reduced to the greatest extent, thereby reducing the temperature change range in the main chamber 2 and further increasing the efficiency and effect of the annealing process.

[0050] The working principle of this utility model is as follows: First, cylinder 19 drives the door panel 15 of the port compartment 11 at the inlet end to rise. At the same time, cylinder 51 at the inlet end drives the outer sprocket 54 to rotate. The outer sprocket 54 synchronously drives the transmission sprocket 34 and the transmission sprocket 35 to rotate, thereby causing the take-up and untake-down roller 32 to take up the wire rope 36 and drive the partition plate 37 to rise. Then, the batch of aluminum-magnesium alloys are placed one by one on the auxiliary roller 12 of the port compartment 11 at the inlet end, and the aluminum-magnesium alloys are pushed to move in a straight line into the transmission roller 63 in the main compartment 2. Then, the partition plate 37 is lowered, thereby allowing the main compartment 2 to move in a straight line into the main compartment 2. The interior of chamber 2 becomes a sealed space; high-temperature steam enters the main pipe 71 through the inlet pipe 72 and diffuses the high temperature into the main chamber 2. At the same time, multiple motors 41 drive multiple fans 46 to operate. The airflow generated by the multiple fans 46 can blow away the high temperature emitted from the main pipe 71, increasing the flow speed of the high-temperature gas. This can both increase the rate of temperature rise in the main chamber 2 and keep the temperature in various positions in the main chamber 2 even, ensuring the annealing effect of the aluminum-magnesium alloy. The partition plates 37 at both ends of the main chamber 2 serve to prevent the high-temperature air from dissipating to the outside of the main chamber 2.

[0051] When the batch of aluminum-magnesium alloy in the main chamber 2 is heated simultaneously, the door panels 15 and partition plates 37 at both ends of the main chamber 2 are all raised. Then, the motor 61 drives multiple transmission rollers 63 to rotate. The multiple transmission rollers 63 can move the aluminum-magnesium alloy towards the port chamber 11 at the outlet end, so that the aluminum-magnesium alloy moves to the auxiliary roller 12 at the outlet end. At the same time, the next batch of aluminum-magnesium alloy that needs to be heated moves to the auxiliary roller 12 at the inlet end and enters the main chamber 2. Thus, the placement and removal of aluminum-magnesium alloy can be carried out simultaneously, which increases the efficiency of the aluminum-magnesium alloy annealing process.

[0052] When batches of aluminum-magnesium alloy are not simultaneously placed into the main chamber 2, the aluminum-magnesium alloy near the outlet end is heated first because it entered the main chamber 2 earlier. At this time, the door panel 15 and partition plate 37 at the outlet end are raised, and then the transmission roller 63 moves the heated aluminum-magnesium alloy onto the auxiliary roller 12. Then, the door panel 15 and partition plate 37 at the outlet end are lowered and closed. After the door panel 15 and partition plate 37 at the outlet end are lowered and closed, the door panel 15 and partition plate 37 at the inlet end are raised again to allow a new batch of aluminum-magnesium alloy to enter the main chamber 2. This enables the uninterrupted annealing of aluminum-magnesium alloy, increases the efficiency of the annealing process, and because only one end of the door panel 15 and partition plate 37 is opened at a time, the rate at which high-temperature gas escapes from the main chamber 2 can be minimized, thereby reducing the temperature fluctuation range in the main chamber 2 and further increasing the efficiency and effectiveness of the annealing process.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
