Background
When the strip steel is subjected to a tensile test, a steel plate with the same width as the rolled strip steel is firstly cut on a production line, then three sample pieces with the width of 300mm by 10mm are respectively cut from the steel plate in the directions of 0 degrees, 45 degrees and 90 degrees with the rolling direction, wherein the width is at least 8mm, and finally the three sample pieces in different rolling directions are processed into tensile samples meeting the standard requirements for the tensile test.
When samples are taken from a steel plate at 0 °, 45 ° and 90 ° in the rolling direction, the measurement and drawing of the auxiliary line are usually performed by a tape measure on the steel plate, and then the sample is cut piece by a shearing machine, which has the following problems:
(1) the left and right gaps of the shearing blades are different due to the fact that the shearing machine on the production line shears the steel plates for a long time, and the widths of the sheared steel plates are easily different;
(2) when the auxiliary lines are drawn on the steel plates with different widths for cutting the sample, because no reliable reference exists, the measuring tape is used for measuring and drawing the auxiliary lines, and the sample cutting error can be caused;
(3) the three manufactured sample sheets and the rolling direction are not accurate to 0 degree, 45 degrees and 90 degrees, so that the accuracy of mechanical property data obtained by a tensile test is reduced, and the rating of a strip steel product is influenced.
