Testing device used for simulating controlled cooling of steel material after rolling

Abstract

The invention discloses a testing device used for simulating controlled cooling of a steel material after rolling, including a steel walking mechanism, a steel cooling mechanism and a testing mechanism, wherein the testing mechanism comprises a temperature sensor for detecting the temperature of a sample, the steel cooling mechanism comprises a first group of spray assemblies, an upper rotating cylinder, a second group of spray assemblies and a lower rotating cylinder, the first group of spray assemblies are installed on the upper rotating cylinder, the upper rotating cylinder is movably arranged above the steel walking mechanism, the second group of spray assemblies are arranged below the lower rotating cylinder, and the lower rotating cylinder is movably arranged below the steel walking mechanism. By adopting the technical solution of respectively arranging the first group of spray assemblies and the second group of spray assemblies on the upper rotating cylinder and the lower rotating cylinder, the floor space of the steel cooling mechanism is reduced, therefore the floor space of the testing device is reduced. When different spray assemblies are needed, the rotating cylinder is just rotated to make the corresponding spray assembly to be in operating position. The testing device is suitable for simulating controlled cooling tests of the steel material after rolling.

Description

technical field [0001] The invention relates to a test device for steel materials, in particular to a test device for simulating controlled cooling of steel materials after rolling. Background technique [0002] At present, TMCP (Thermo-Mechanical Control Process: thermomechanical control process, usually called controlled rolling and controlled cooling process) is a relatively common technology in the development and application of steel rolling and process products. Achieved by adding microalloying elements. However, traditional TMCP not only requires high equipment capabilities, but also consumes resources. In order to overcome the shortcomings of the traditional TMCP process, a new generation of TMCP technology represented by ultra-fast cooling technology came into being. This new generation of TMCP technology realizes the control of the cooling path, thereby controlling the phase transformation structure after cooling and obtaining different properties. It not only ma...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the several groups of spray assemblies are lined up along the walking direction of the steel walking mechanism, the steel cooling mechanism occupies a relatively large area, resulting in a relatively large area occupied by the test device;

[0005] 2. Since the test device does not have a heating mechanism, the sample needs to be heated in other places before placing it on the steel walking mechanism, which is very inconvenient to operate, and the temperature change of the sample cannot be monitored in real time
