Description

Technical Field

[0002] T6 is a heat treatment state of aluminum alloy, and its corresponding English is Temperature 6. Aluminum alloy in this state has high strength and hardness, as well as good plasticity, toughness and corrosion resistance. T6 treated aluminum alloy is usually used to manufacture parts that require higher strength, such as parts in the fields of automobiles, aircraft, aerospace, etc.

[0003] During the processing of aluminum alloys, different heat treatment processes can change the microstructure of the alloy to obtain different properties. T6 heat treatment is a common heat treatment process that strengthens the aluminum alloy to improve its mechanical properties. The specific treatment method is to use an aluminum alloy T6 heat treatment furnace to heat the aluminum alloy to a certain temperature (usually between 500-600 degrees Celsius), maintain it for a certain period of time, and then cool it quickly. This process can cause some phases in the aluminum alloy to change and form a more stable phase, thereby improving the strength and hardness of the alloy. Existing aluminum alloy T6 heat treatment furnaces include single-section heat treatment furnaces and multi-section heat treatment furnaces; the single-section heat treatment furnace has a flip door, through which materials are loaded and unloaded. Although this type of heat treatment furnace has better sealing and can prevent high temperature leakage, the processing efficiency is low and manual loading and unloading is required, which is not convenient for rapid cooling of subsequent processes and there is a risk of high temperature burns; the multi-section heat treatment furnace uses a conveyor belt to pass the product through several sections of the baking furnace body in turn, with a higher processing efficiency, it can realize automatic loading and unloading, and can be connected with the subsequent process to achieve rapid cooling, but since this type of heat treatment furnace does not have an inlet and outlet door and there are gaps between the multi-section baking furnace bodies, there will be a phenomenon of high temperature leakage.
