Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, and in particular relates to an aluminum rod homogenizing heating furnace. Background Art

[0002] In the process of casting aluminum bars, there will be some defects such as segregation and pores inside the aluminum bars, which will affect the quality and uniformity of the aluminum alloy bars. Therefore, it is necessary to homogenize the aluminum bars. The aluminum bars are placed in a homogenizing furnace for high-temperature heating to rearrange the grains inside the aluminum bars, eliminate impurities and internal stress, and improve the mechanical and physical properties of the aluminum material, thereby achieving homogenization of the aluminum bars.

[0003] When processing aluminum rods, the existing homogenizing furnace directly ventilates and cools the aluminum rods after heating. The actual problem encountered is that during the cooling process, the high-temperature aluminum rods are continuously in contact with the outside air and react chemically with the oxygen in the air. In particular, the high temperature promotes the oxidation reaction of the aluminum rods to form a thick oxide film on the surface of the aluminum rods. The formation of the thick oxide film will affect the mechanical properties of the aluminum rods, such as strength, hardness and toughness, thereby affecting the quality of the aluminum rod products. Utility Model Content

[0004] The present application proposes an aluminum rod homogenizing heating furnace to prevent the high-temperature aluminum rod from continuously reacting chemically with oxygen in the outside air after contacting the outside air during the cooling process after heating, so as to improve the quality of the aluminum rod.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A homogenizing heating furnace for aluminum rods comprises a furnace body, a furnace door is arranged on the side of the furnace body, a bracket and a heating plate are installed in the furnace body, the heating plate is arranged on one side of the bracket, a heat dissipation duct is connected to the side wall of the furnace body, the heat dissipation duct is installed in a bent shape outside the furnace body, an air inlet and an air outlet of the heat dissipation duct are respectively connected to the inside of the furnace body, a fan is installed at the air outlet of the heat dissipation duct, and a buckle is installed on the side of the furnace door.

[0007] In one embodiment of the present application, the bracket includes a support plate, and a hook plate is installed on the support plate.

[0008] In one embodiment of the present application, a plurality of heating plates are installed in the furnace body, and the plurality of heating plates are evenly arranged in the furnace body.

[0009] In one embodiment of the present application, a plurality of circular fins are installed on the heat dissipation duct.

[0010] In one embodiment of the present application, a plurality of support columns are installed at the bottom of the heat dissipation duct.

[0011] In one embodiment of the present application, a valve is installed at the air inlet of the heat dissipation air duct.

[0012] In one embodiment of the present application, the exterior of the furnace body is coated with a thermal insulation layer.

[0013] In summary, the technical solution proposed in the present application includes the following beneficial technical effects: the aluminum rod is placed on the bracket, the furnace body is heated by the heating plate, and the aluminum rod is heated homogeneously. After the heating is completed, the fan is turned on to blow the air of the heat dissipation duct into the furnace body, and the air in the heat dissipation duct is blown out to cause negative pressure in the heat dissipation duct, thereby prompting the heat dissipation duct to suck the high-temperature air in the furnace body into the heat dissipation duct through the air inlet, so that the gas in the furnace circulates in the heat dissipation duct. When the hot air in the furnace flows through the heat dissipation duct, the temperature is reduced by heat exchange with the outside through the outer wall of the heat dissipation duct. The temperature in the furnace body is reduced to room temperature by multiple cycles in the heat dissipation duct to exchange heat with the outside. On the one hand, the gas in the furnace is circulated internally through the furnace and the heat dissipation duct, which avoids the high-temperature aluminum rod from continuously undergoing oxidation reaction with oxygen after contacting with the external air to form a thick oxide film, which is beneficial to improving the quality of the aluminum rod product. On the other hand, the gas in the furnace is driven by the fan to circulate through the heat dissipation duct to dissipate heat. Compared with cooling the furnace body while leaving it to stand, the cooling speed in the furnace body is increased, which is beneficial to improving production efficiency.

[0029] This embodiment provides an aluminum rod homogenizing heating furnace, see Figure 1-Figure 5As shown, it includes a furnace body 1, a furnace door 2 is arranged on the side of the furnace body 1, a bracket 3 and a heating plate 11 are installed in the furnace body 1, the heating plate 11 is arranged on one side of the bracket 3, a heat dissipation duct 4 is connected to the side wall of the furnace body 1, the heat dissipation duct 4 is installed in a bent shape outside the furnace body 1, the air inlet 41 and the air outlet 42 of the heat dissipation duct 4 are respectively connected to the furnace body 1, a fan 5 is installed at the air outlet 42 of the heat dissipation duct 4, and a buckle 21 is installed on the side of the furnace door 2.

[0030] In the above embodiment, a bracket 3 and a heating plate 11 are installed in the furnace body 1, and the heating plate 11 is arranged on one side of the bracket 3. The aluminum rod is placed on the bracket 3, and the furnace body 1 is heated by the heating plate 11 to heat the aluminum rod uniformly. The side wall of the furnace body 1 is connected to a heat dissipation duct 4, and the air inlet 41 and the air outlet 42 of the heat dissipation duct 4 are respectively connected to the furnace body 1. After the heating is completed, the fan 5 is turned on to blow the air of the heat dissipation duct 4 into the furnace body 1, and the air in the heat dissipation duct 4 is blown out to cause negative pressure in the heat dissipation duct 4, thereby prompting the heat dissipation duct 4 to suck the high-temperature air in the furnace body 1 into the heat dissipation duct 4 through the air inlet 41, so that the gas in the furnace is in the heat dissipation duct 4. In the internal circulation, when the hot air in the furnace flows through the heat dissipation duct 4, the temperature is reduced by heat exchange with the outside through the outer wall of the heat dissipation duct 4. The temperature in the furnace body 1 is reduced to room temperature by multiple cycles in the heat dissipation duct 4 and heat exchange with the outside. In the process of the heat dissipation duct 4 circulation, the gas in the furnace is to realize the gradual decrease of the temperature in the furnace body 1. Compared with directly ventilating and cooling the furnace, the temperature difference between the high-temperature aluminum rod and the normal temperature air is large. The temperature difference is too large or the cooling speed is too fast, so that the cooling speed of different parts of the aluminum rod is different, resulting in inconsistent thermal expansion and contraction inside the aluminum rod and uneven deformation, thereby causing uneven distribution of internal stress, affecting the stability and reliability of the material. The circulation and gradual cooling in the furnace body 1 can realize uniform cooling of the high-temperature aluminum rod treated by homogenization, gradually balance the stress distribution inside the material, thereby improving the stability and reliability of the aluminum rod material. In addition, the gas in the furnace is internally circulated through the furnace and the heat dissipation duct 4, which avoids the high-temperature aluminum rod from continuously reacting with external oxygen to form a thick oxide film after contacting with the external air, which is beneficial to improving the quality of the aluminum rod product. On the other hand, the gas in the furnace is driven by the fan 5 to circulate and dissipate heat through the heat dissipation duct 4, which increases the cooling speed in the furnace body 1 compared to cooling the furnace body 1 at rest, which is beneficial to improving production efficiency.

[0031] In one embodiment of the present application, see Figure 3 As shown, the bracket 3 includes a support plate 31 , and a hook plate 32 is installed on the side wall of the support plate 31 .

[0032] In the above embodiment, a hook plate 32 is installed on the side wall of the support plate 31. The aluminum rod is cylindrical and has a curved outer surface, which is easy to roll. The aluminum rod can be limited and fixed by the slot of the hook plate 32 to prevent the aluminum rod from rolling and slipping when placed on the bracket 3, which is beneficial to improve the stability of the aluminum rod and prevent the aluminum rod from falling and injuring the staff.

[0033] In one embodiment of the present application, refer to Figure 2 As shown, a plurality of heating plates 11 are installed in the furnace body 1 , and the plurality of heating plates 11 are evenly arranged in the furnace body 1 .

[0034] In the above embodiment, a plurality of heating plates 11 are evenly arranged in the furnace body 1, so that when the heating plates 11 heat the furnace body 1, the temperature in the furnace body 1 is evenly increased, thereby preventing the aluminum rod from being heated unevenly in the furnace body 1. Uneven heating may cause uneven deformation inside the aluminum rod, thereby causing uneven distribution of internal stress, which may lead to cracks or deformation of the material, and is beneficial to improving the quality of the aluminum rod.

[0035] In one embodiment of the present application, see Figure 4 As shown, a plurality of circular fins 43 are installed on the heat dissipation duct 4.

[0036] In the above embodiment, the outer wall of the heat dissipation duct 4 is connected with a plurality of circular fins 43 in order to increase the heat exchange area between the heat dissipation duct 4 and the outside, so that the high temperature gas in the heat dissipation duct 4 and the room temperature gas outside can be fully exchanged and cooled, which is beneficial to improving the heat exchange efficiency.

[0037] In one embodiment of the present application, see Figure 4 As shown, a plurality of support columns 44 are installed at the bottom of the heat dissipation duct 4.

[0038] In the above embodiment, the support column 44 supports the heat dissipation duct 4 to prevent the heat dissipation duct 4 from bending and deforming under the impact of the internal airflow, which is beneficial to improving the stability of the operation of the heat dissipation duct 4.

[0039] In one embodiment of the present application, see Figure 5 As shown, a valve 411 is installed at the air inlet of the heat dissipation air duct 4.

[0040] In the above embodiment, closing the valve 411 when heating is performed in the furnace body 1 can seal the heat dissipation duct 4, cut off the fluidity of the gas in the heat dissipation duct 4, and prevent the gas from flowing in the heat dissipation duct 4 when heating is performed in the furnace body 1, thereby preventing heat loss in the furnace body 1, which is beneficial to improving the heating efficiency of the furnace body 1.

[0041] In one embodiment of the present application, the furnace body 1 is externally coated with a heat-insulating layer.

[0042] In the above embodiment, the thermal insulation layer can, on the one hand, play a role of thermal insulation to prevent excess heat loss during heating in the furnace body 1, thereby saving energy consumed for heating; on the other hand, the thermal insulation layer can play a role of thermal insulation to prevent the outside of the furnace body 1 from being too hot and causing injuries to workers due to accidental touch.

[0043] In the actual use of this application: a bracket 3 and a heating plate 11 are installed in the furnace body 1, and the heating plate 11 is arranged on one side of the bracket 3, the aluminum rod is placed on the bracket 3, the furnace body 1 is heated by the heating plate 11, and the aluminum rod is heated uniformly, and the side wall of the furnace body 1 is connected to a heat dissipation duct 4, and the air inlet 41 and the air outlet 42 of the heat dissipation duct 4 are respectively connected to the furnace body 1. After the heating is completed, the fan 5 is turned on to blow the air of the heat dissipation duct 4 into the furnace body 1, and the air in the heat dissipation duct 4 is blown out to cause a negative pressure in the heat dissipation duct 4, thereby prompting the heat dissipation duct 4 to suck the high-temperature air in the furnace body 1 into the heat dissipation duct 4 through the air inlet 41, so that the gas in the furnace circulates in the heat dissipation duct 4, and when the hot air in the furnace flows through the heat dissipation duct 4, the temperature is reduced by heat exchange with the outside through the outer wall of the heat dissipation duct 4, and the temperature in the furnace body 1 is reduced to room temperature by multiple circulations in the heat dissipation duct 4 to exchange heat with the outside.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
