The quenching transfer time of Aluminum Alloy Quenching Furnace is a key parameter in the quenching process, which directly affects the final performance of aluminum alloy products.
1. Basic concept and importance of quenching transfer time
Quenching transfer time refers to the interval from the completion of heating of aluminum alloy workpieces in the quenching furnace to the start of cooling after entering the quenching medium (such as water, oil or special gas). For aluminum alloys, this time is extremely critical because the organizational state of aluminum alloys at high temperatures is unstable. If the transfer time is too long, the residence time of the aluminum alloy workpiece in the air will increase, which will cause the surface temperature of the workpiece to drop excessively, and the ideal quenching organization cannot be formed during quenching, which will affect the strength, hardness and corrosion resistance of the material. For example, for high-strength aluminum alloy parts used in the aerospace field, too long quenching transfer time may make the mechanical properties of the parts unable to meet the flight safety standards.
2. Transfer time range of different types of Aluminum Alloy Quenching Furnace
The quenching transfer time of different types and specifications of Aluminum Alloy Quenching Furnace is also different. Generally speaking, the quenching transfer time of a small experimental Aluminum Alloy Quenching Furnace may be between 5 and 15 seconds. This is because the experimental samples are usually small and the requirements for the transfer speed are relatively low. However, the quenching transfer time of a large Aluminum Alloy Quenching Furnace used in industrial production is usually around 10-30 seconds due to the complexity of the furnace structure and operation. Some high-end, highly automated continuous Aluminum Alloy Quenching Furnaces can control the quenching transfer time to 8-12 seconds, and achieve fast and stable transfer through precise mechanical transmission and automatic control systems.
3. Factors affecting quenching transfer time
Quenching transfer time is affected by many factors. The furnace structure is an important aspect. If the furnace door is not designed reasonably and opens and closes slowly, the transfer time will be increased. For example, the transfer time of a quenching furnace with a side-opening furnace door and no fast opening and closing device will be significantly increased. The lifting device of the workpiece is also critical. If the lifting speed is slow and the operation is unstable, the transfer time will inevitably be extended. In addition, the proficiency of the operator and the scientific nature of the operation process will also affect the quenching transfer time. If the worker is not proficient in the operation, the workpiece cannot be transferred to the quenching medium in time after heating is completed, which will also cause the transfer time to be too long.
4. How to optimize the quenching transfer time
In order to optimize the quenching transfer time, first of all, we should pay attention to the design of the furnace door and the performance of the lifting device in the equipment selection. Choose a quenching furnace with the function of quickly opening and closing the furnace door, and equip it with high-speed and stable lifting equipment. At the same time, strengthen the training of operators and formulate scientific and reasonable operation procedures so that the workpiece can be quickly and accurately transferred to the quenching medium after heating is completed. For quenching furnaces with a high degree of automation, the control system can also be optimized to achieve seamless connection between the heating completion signal and the lifting and transfer actions, thereby minimizing the quenching transfer time and improving the quality and production efficiency of aluminum alloy quenching.
