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.

Abstract

The invention discloses a high-flux spray quenching spray pipe device. The device comprises a spray quenching module and more than one maneuvering module, wherein the maneuvering modules are respectively connected with the spray quenching module, the spray quenching module comprises a spray quenching pool, a sample holder, a spray pipe, a nozzle, a metal pipe float flowmeter, a pneumatic diaphragmcontrol valve, a booster pump and a water tank, the maneuvering module comprises a servo motor, a servo motor supporting frame, two supporting rods, a spraying pipe fixing block, a sliding block, a Z-shaped crank, two supporting shafts and two supporting rods, and the sliding block comprises a cross beam, a connecting rod, a cross beam, a cross beam and two sliding sleeves. The servo motor rotates to drive a Z-shaped crank to do circular motion, so the spray pipe moves up and down, and a distance from the nozzle to a bottom end of the sample is adjusted. The device can be used for carrying out spray quenching experiments under different spray quenching intensities to determine a heat exchange coefficient of the cooling medium and the metal surface, characterize the metal quenching microstructure and test performance of the metal quenching microstructure.

Description

technical field [0001] The invention belongs to the field of quenching and cooling performance characterization of metal materials and material processing, and in particular relates to a high-throughput spray quenching nozzle device. [0002] technical background [0003] The core of material genetic engineering is to build three platforms for material innovation, including material database platform, high-throughput numerical simulation computing platform and high-throughput test characterization platform. Through collaborative innovation and integration, the design and application of materials can be accelerated to achieve shortened The purpose of half the R&D cycle and half of the R&D cost.
