Quenching cooling time of aluminum alloy quenching furnace

[China Aluminum Industry Network] The introduction of the function and principle of the aluminum alloy quenching furnace must be introduced by many people. In fact, it can be used as a kind of boiler to introduce them. It is possible to understand how to use it, but the aluminum alloy quenching furnace has some special features. I think this is closely related to the application, because it is mainly used for aluminum alloy products, then the shape and size of the article have an impact on how to use the aluminum alloy quenching furnace, we said a lot in its quenching process, today talk about the cooling rate .

The cooling rate at the time of quenching means that it is necessary to ensure that the saturated solid solution is fixed without decomposing to prevent precipitation of the strengthening phase and reduce the mechanical properties of the quenching aging. Therefore, the faster the cooling rate at quenching, the better. However, the greater the cooling rate, the greater the residual stress and residual deformation of the quenched product. Therefore, the cooling rate must be determined according to different alloys and products of different shapes and sizes. Generally, the quenching of the alloy is sensitive to the cooling speed, and the selected cooling rate is large. In fact, when it comes to this, it is obvious that everyone can see that the aluminum alloy quenching furnace is much more complex than the mesh belt furnace. This is related to their scope of use.

For products with different shapes and sizes, different cooling speeds should be used, which is usually achieved by adjusting the temperature of the quenching medium. For the simple shape, small and medium-sized, bar can be quenched with room temperature water, for the shape of the complex, the wall thickness difference of the profiles can be used medium-temperature water quenching. For products that are particularly susceptible to deformation, the water can even be raised to a higher temperature for quenching. With the increase of water temperature, the mechanical properties and corrosion resistance of quenched products are reduced. There is a lot of knowledge about the quenching process for aluminum alloy quenching furnaces.
