Abstract

The invention relates to a metal material end surface quenching test machine. A prepared cylindrical sample is uniformly heated by the induction coil of a high frequency generator, the center of the upper surface of the sample is provided with a blind hole for arranging a thermocouple to collect the change of the temperature of the sample, the heating part is processed to prepare a water tank, a water injection nozzle is arranged under the sample, a cooling water tube is arranged above the sample, the water injection quenching time is controlled by a water injection control valve arranged on a middle water tube of the water injection nozzle, the water outlet time of cooling water is controlled by a cooling water control valve arranged on a cooling water tube in a cooling water tank, and a used water resource is collected in a cycle water tank and is recycled through utilizing a water pump. The machine integrates heating, quenching and cooling, and realizes the heating, the quenching and the cooling automatically, so the sample accuracy is improved.

Description

technical field

[0001] The invention belongs to the technical field of metal material heat treatment, in particular to a metal material end face quenching tester. Background technique

[0002] Quenching of metal materials is a commonly used method in heat treatment, that is, after heating the heat treatment workpiece to a certain temperature, and keeping it at a certain temperature and a certain time, the workpiece is completely heated from the inside to the outside, and then the workpiece is heated at the fastest speed. It is cooled to obtain the heat treatment process of the martensitic structure. The main purpose of quenching is to change its metallographic structure in order to obtain the required structure and properties after subsequent tempering at different temperatures. The quality of quenching depends on the three elements of quenching, namely the heating temperature, holding time and cooling medium.

[0003] The hardenability of steel refers to the ability of st...
