A spray quenching process research device and its use method

Abstract

The invention discloses a spray quenching process research device. The spray quenching process research device comprises a base. A heating furnace, a quenching zone located on one side of the heating furnace and a moving assembly used for moving a workpiece to the heating furnace or the quenching zone are arranged on the base. A spraying assembly and a water tank located below the spraying assembly are arranged in the quenching zone. The spraying assembly comprises a spraying base plate and a quenching media pressurization supply assembly. The spraying base plate is provided with a plurality of mounting holes. The mounting holes are connected with the quenching media pressurization supply assembly. At least one mounting hole is provided with a spray nozzle. The other mounting holes not provided with spray nozzles are closed through detachable blocking pieces. The spray quenching process research device has the advantages that a spray cooling field is adjustable; the device is convenient to use; the spray quenching process research cycle can be shortened; and the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to a spray quenching process research device especially suitable for aluminum alloy components and a use method thereof. Background technique [0002] Aluminum alloy components with low density, high specific strength, corrosion resistance and other excellent properties that can be strengthened by heat treatment are widely used in the aerospace field. In order to improve the comprehensive performance of products, such as strength, toughness, corrosion resistance and fatigue resistance, solid solution- Quenching-aging treatment. Quenching is the key link, but the quenching process is prone to excessive residual stress and uneven performance distribution, resulting in poor dimensional stability of components, serious subsequent machining deformation, reduced serviceability of materials, and reduced fatigue life. The large deformation caused by excessive residual stress of...

Problems solved by technology

At present, there are two main methods for quenching technology research: one is to conduct process research through simulation, but its accuracy is affected by many factors, and the reliability needs to be improved; the other is to use formal components to carry out process experiments on spray quenching equipment research, but it is difficult to collect experimental process parameters, such as temperature changes of components, time-consuming and labor-intensive process, and high cost, etc.
