Background
For steel plants producing thick plates, the requirements on the directional performance of the thickness of the thick plate are more and more common along with the gradual improvement of the comprehensive quality requirements of users on the thick plate. Compared with a strip sample parallel to the rolling direction or perpendicular to the rolling direction, the performance detection in the thickness direction of a common thick plate is limited by the thickness range of the plate, and the plate cannot be processed into a tensile sample which can be directly tested by a testing machine, so that the testing machine cannot directly test the sample, and the thickness direction test must be realized by an auxiliary processing means. The current common method is as follows: firstly, a part to be tested in the thickness direction of a thick plate is manufactured into a square test block with the length of about 30mm, then two ends of the test block are respectively welded with a bar-shaped test sample with the length of about 200mm by a friction welding machine or other modes, after cooling, the test block part is turned to the diameter (10mm or 6mm) required by the standard by a lathe or a machining center and other equipment, then the bar-shaped parts welded at the two ends are placed in a jaw of a testing machine, the testing machine is started to apply tension until the middle turned thickness direction part is broken, and the broken part is measured, so that the performance test in the thickness direction of the thick plate is realized. The purpose of welding the two ends of the test piece in the thickness direction into a rod shape is to clamp and apply force to the rod-shaped part so as to realize the tensile test of the test piece in the thickness direction. The main process is shown in fig. 4.
The main problems existing in the prior method are that the whole testing process is long in time consumption due to the welding, cooling and reprocessing processes, and more materials, equipment and the like are wasted in the whole process. Meanwhile, if the welding quality is unqualified or the welding seam is broken during testing, the testing cannot be carried out, and the processes of sampling, sample preparation, welding, processing, testing and the like must be carried out again for retesting.
