Technical Field
The invention belongs to the technical field of air-cooled quenching, and particularly relates to an online air-cooled quenching device for an aluminum casting.
Background
Air cooling is one type of cooling method, i.e. using air as a medium to cool an object to be cooled. Typically, either the surface area of the object to be cooled is increased, or the rate of air flow through the object per unit time is increased, or both. The former can be achieved by adding heat sinks to the surface of the object, and the heat sinks are usually hung outside the object or fixed on the object to make the heat dissipation more efficient. The latter can use fan (blower) to strengthen ventilation and cooling effect. In most cases, the cooling efficiency can be greatly improved by adding the cooling fins. In any case, the air used is at a lower temperature than the object and its surface to remove heat, due to the second law of thermodynamics constraint that it is not possible to transfer heat from a low temperature object to a high temperature object without causing other changes. When the aluminum casting is processed, after the aluminum casting is just formed and demoulded, the traditional processing method is natural aging processing, the purpose of releasing surface thermal stress is achieved by placing the casting in the air and waiting for the heat to be naturally dissipated, the processing time is long, and the problems of cold cracking and the like can occur due to the change of internal and external temperature along with the time change.
