Before xiaobao has introduced 2024 aluminum plate solution treatment method, next 2024 aluminum plate manufacturer to introduce to you, 2024 aluminum plate solution treatment heat preservation time needs to consider factors.

The properties of 2024 aluminum plate hardening holding time is mainly based on quenching heating temperature, alloy, the product type and previous solid solution state organization (intensive phase characteristics and size distribution), the product shape (including the size of cross section thickness), heating mode (salt bath furnace and air circulation furnace, continuous or discontinuous heating), and furnace heating medium and cooling way, and to determine the performance requirements of organization factors.

The main factors to consider are:

1. Product shape.The heat preservation working time of quenching temperature heating is closely related to the shape of the product such as the size of the design thickness of the section.The larger the section, the longer the insulation time.For 2024 aluminum semi-finished products, the shape of small and large cross sections changes, the quenching time should be extended, so that the quenching stage is completely dissolved.

2. Heating temperature.Quenching incubation time is closely related to the heating temperature.The higher the temperature, the shorter the holding time.

3. Plastic deformation degree and 2024 aluminum plate product type.Deformation, with smaller dimensions, the greater the degree of enhancement, the shorter the retention time.

4. Original organization.After the 2024 aluminum plate is quenched in advance, the dissolved fire can be reheated, which can significantly shorten the working time of heat preservation.The dissolution rate in the slow hardening phase is considerably higher than the dissolution rate in the cold phase before annealing.

5. Uniformity of 2024 aluminum blank.For the 2024 aluminum plate with insufficient homogeneity, the residual reinforcement learning stage is studied more and larger, so the insulation working
