Description

High-flux spray quenching spray pipe device
Technical Field
The invention belongs to the field of metal material quenching cooling performance characterization and material processing, and particularly relates to a high-flux spray quenching nozzle device.
Technical Field
The core of the material genetic engineering is three platforms for constructing a material innovation foundation, including a material database platform, a high-flux numerical simulation calculation platform and a high-flux test characterization platform, and the design and application of the material are accelerated through collaborative innovation and integration, so that the aims of shortening a half of research and development period and reducing a half of research and development cost are fulfilled. The establishment of the material database needs a large amount of data, and the traditional sequential iteration testing method has low efficiency, high cost and long time and is difficult to meet the requirements of the current society on material research and development. The high-throughput test characterization can complete multiple groups of experiments at one time, and a sequential iteration method adopted in the material research and development process is changed into parallel processing, so that the efficiency of material test characterization is greatly improved.
The heat treatment is an indispensable process for improving the structure and the performance of the material and determines the final quality of the product, and the hardenability are important material physical property parameters in the formulation and optimization of the heat treatment process of the metal material. In 1938 Jominy first obtained an end-quench curve using an end-quench test, which was often used to measure the hardenability and hardenability of materials. In addition, the axial cooling rates of the end quenched specimens were not uniform, resulting in a different texture along the axial direction of the specimens. Therefore, end quench experiments are also often used to verify numerical simulation calculations of the temperature and tissue fields of the heat treatment quenching process.
CN106636580A proposes a tail end quenching experimental device, which adjusts the spray quenching strength through a diverter to keep the spray quenching strength stable, thereby meeting the requirements of GB/T225-2006 method for testing tail end quenching of steel hardenability, but the device is difficult to carry out tail end quenching experiment on non-national standard samples. In addition, the device can only carry out terminal quenching experiment on one sample at a time, and is difficult to meet the requirement of rapidly collecting a large amount of experimental data and establishing a material genetic engineering database.
CN204589247U proposes a variable water-space intermittent frequency end quenching simulation device, which can perform end quenching experiments on single samples of different sizes at a certain spray quenching strength by manually adjusting the distance from a nozzle to the bottom end of the sample and the pressure of water. However, the device cannot meet the requirements of changing the spray quenching strength and the distance from the nozzle to the bottom end of the sample in the experiment, and in addition, the device is similar to the tail end quenching experimental device provided by CN106636580A, and only one sample can be subjected to the tail end quenching experiment at one time.
