Problems solved by technology

[0005] CN106636580A proposes a terminal quenching experimental device, which adjusts the spray quenching intensity through a flow divider to keep the spray quenching intensity stable, thereby meeting the requirements of GB / T225-2006 "End Quenching Test Method for Steel Hardenability", but the device Difficult to perform terminal quenching experiments on non-national standard samples
However, this device cannot meet the requirements of changing the spray quenching intensity and the distance from the nozzle to the bottom of the sample in the experiment. In addition, this device is similar to the end quenching experimental device proposed by CN106636580A, and only one sample can be subjected to the end quenching experiment at a time.
