Background

The seamless steel pipe is an important variety in the steel industry, and has the advantages of high production difficulty, high technical content and wide application range. The production of seamless steel pipes is composed of the following main processes according to different varieties: smelting, rolling, heat treatment and processing. According to the requirements of product standards, various technical indexes of the steel pipe are respectively completed by various working procedures, the performance index of the steel pipe is closely related to the design and rolling process of steel grades but mainly depends on a heat treatment working procedure, and in a certain sense, the working procedure for finally determining the product performance is heat treatment.

Quenching and cooling in heat treatment are important processes, as is well known, quenching is a technological process for rapidly cooling a workpiece from high temperature to low temperature, and after quenching and tempering are carried out on a steel pipe, the structure, the performance and the like of the steel pipe meet the standard requirements, so the design of the quenching temperature is very important, the performance result of the product is seriously influenced, and the early analysis of the hardenability of the material is particularly important. According to the analysis of the metal hardenability, whether the quenching temperature meets the requirements of the seamless steel pipe on the material and the wall thickness can be determined, so that the steel pipe waste caused by design errors and unqualified performance is avoided. However, no means exist to analyze the hardenability of the material, making this test difficult to perform.

Therefore, the utility model provides a device of test metal material hardenability can conveniently carry out the test of metal material hardenability.
