Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for iron and aluminum alloys, specifically to a heat treatment device for homogenizing iron and aluminum alloys. Background Technology

[0002] The homogenization heat treatment process for iron and aluminum alloys is a key process that eliminates the segregation of components inside the ingot by heating at high temperature for a long time. The heat treatment process generally includes three processes: heating, holding, and cooling, but sometimes only two processes are involved: heating and cooling.

[0003] Chinese Patent CN215560443U discloses an integrated heat treatment method for homogenizing annealing of aluminum alloy profiles. The method includes a base with a housing on top. Inside the housing are a preheating chamber, a heating chamber, and a cooling chamber, arranged sequentially. A feed inlet is located on one side of the housing. A support rod is positioned below the preheating chamber, and a drive shaft is connected above the support rod. A drive roller is sleeved on the outside of the drive shaft. Several electromagnetic heating coils are located on one side of the drive shaft and inside the heating chamber. Several blades are positioned above the electromagnetic heating coils. This invention, by using a drive roller and electromagnetic heating coils, can uniformly heat the material. During cooling, the material can be dispersed across different pallets, preventing uneven temperature due to material accumulation. Simultaneously, the heat generated during heating can be transferred to the preheating chamber to preheat the material, thereby reducing energy consumption and production costs.

[0004] The above technology has the following problems during operation: The above device lacks cleaning components for iron and aluminum alloys, which causes the oil on the iron and aluminum alloys to decompose when heated, producing gas (such as hydrogen), forming bubbles on the metal surface, damaging the integrity of the oxide film, and the oil also hinders the diffusion of alloy elements, resulting in uneven composition, affecting the mechanical properties after heat treatment, and even residual grease may penetrate into the inner layer of the oxide film, causing local corrosion.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a heat treatment device for homogenizing iron and aluminum alloys, including a box 1 with openings at both ends. The interior of the box 1 is divided into a cleaning chamber 101, a preheating chamber 102, a heating chamber 103, and a cooling chamber 104 from left to right by a partition curtain 5. A transmission track 7 is provided at the bottom of the box 1, which passes through the cleaning chamber 101, the preheating chamber 102, the heating chamber 103, and the cooling chamber 104 in sequence. The inner walls on both sides of the cleaning chamber 101 are respectively provided with cleaning rollers 2 and cleaning plates 4 from left to right. Heating resistance wires 8 are installed on the inner walls on both sides of the heating chamber 103. A water spray pipe 14 extending into the cleaning chamber 101 is provided on the outer side of the cleaning chamber 101.

[0023] In this embodiment, the tops of the heating chamber 103 and the preheating chamber 102 are connected by a gas supply pipe 12, and a vacuum pump 9 is installed on the gas supply pipe 12. By providing the gas supply pipe 12 and the vacuum pump 9, hot gas in the heating chamber 103 can be extracted and sent to the preheating chamber 102, thereby heating the preheating chamber 102. The preheating chamber 102 is used to preheat the iron-aluminum alloy, so that the water stains on the iron-aluminum alloy in the preheating chamber 102 are evaporated clean.

[0024] In this embodiment, a geared motor 3 is installed on the top of the housing 1, and the top of the cleaning roller 2 penetrates through the housing 1. Both the end of the cleaning roller 2 and the output end of the geared motor 3 are equipped with sprockets, and the sprockets are connected in pairs via chain drive. With this configuration, the geared motor 3, through the cooperation of the chain and sprockets, can drive the cleaning roller 2 to rotate rapidly, and the cleaning roller 2, in conjunction with the water spray pipe 14, can rinse the surface of the iron-aluminum alloy.

[0025] In this embodiment, a hydraulic cylinder is fixedly connected to the inner wall of the housing 1 on the outer side of the cleaning plate 4, and a cleaning surface for cleaning the friction of the iron and aluminum alloy is provided on the inner side of the cleaning plate 4. The position of the cleaning plate 4 can be adjusted by the hydraulic cylinder so that the cleaning surface on the inner side of the cleaning plate 4 can wipe the surface of the iron and aluminum alloy and absorb the water stains on it.

[0026] In this embodiment, the partition curtain 5 is made of high-temperature resistant heat-insulating material, and the partition curtain 5 can be opened by an iron-aluminum alloy. The partition curtain 5 can also be made of ceramic fiber.

[0027] In this embodiment, the transmission track 7 has several equally spaced fixing holes 701, and fixing blocks 6 are installed on the fixing holes 701 by bolts. Through the cooperation of the fixing blocks 6 and the fixing holes 701, the iron and aluminum alloy plates can be clamped and fixed, allowing the iron and aluminum alloy to move along the transmission track 7.

[0028] In this embodiment, movable windows 10 corresponding to the transmission track 7 are provided on the front and rear sides of the cleaning chamber 101 and the cooling chamber 104. The movable windows 10 allow for the control of the assembly and disassembly of the fixed block 6.

[0029] In this embodiment, movable doors 11 are provided at the openings at both ends of the housing 1.

[0030] In this embodiment, an air exchange pump 13 is installed through the top of the cleaning chamber 101. By installing the air exchange pump 13, oxygen can be extracted from the chamber 1, providing an oxygen-free environment for the homogenization heat treatment of the iron-aluminum alloy.

[0031] Working principle:

[0032] The iron-aluminum alloy plate is vertically placed into the cleaning chamber 101 through the left opening of the housing 1. The fixing block 6 is fixed to both sides of the iron-aluminum alloy plate through the movable window 10, and the iron-aluminum alloy is limited and fixed by the fixing block 6. The iron-aluminum alloy plate is moved by the transmission track 7. The two sides of the iron-aluminum alloy are rinsed by the water spray pipe 14 and the cleaning roller 2 to clean the iron-aluminum alloy. After rinsing, the iron-aluminum alloy passes between the two cleaning plates 4 and is wiped by the cleaning plates 4 to remove most of the water stains. When the iron-aluminum alloy moves to the preheating chamber 102, the hot air in the preheating chamber 102 is used to preheat the iron-aluminum alloy to remove the water stains on the surface. The iron-aluminum alloy plate is then moved to the heating chamber 103 for heating treatment. After the iron-aluminum alloy is homogenized and the heat treatment is completed, the iron-aluminum alloy plate is moved to the cooling chamber 104 for cooling by the transmission track 7.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
