Section 1 Brief description of steel plates
Medium and thick steel plate products have wide applications, such as shipbuilding, construction, large diameter welded pipe and boiler. Usually, the thickness of the plate is between 10 mm and 200 mm.
Section 2 Detailed information on steel plates
1. Mechanical performance test of medium and thick steel plate
Medium and thick steel plate products have wide applications, such as shipbuilding, construction, large diameter welded pipe and boiler. Usually, the thickness of the plate is between 10 mm and 200 mm. This classification identifies the material composition (carbon content, alloy, etc.) of the sheet metal, indicating that its yield strength and tensile strength are higher than the predetermined value, the section shrinkage and elongation are within the tolerance range, and the thick sheet steel meets the minimum hardness requirements. It is essential to ensure that the medium and thick steel plates meet the requirements of the classification standards issued for the design of safe and reliable products.
2. Tensile test performance of steel plates
Tensile test of medium and thick steel plate mainly tests its tensile properties, such as yield strength and ultimate strength, section shrinkage and elongation. The test system should be strong and durable while ensuring the accuracy and stability of the test results. The testing machine and its fixture and measuring system must not be affected by surface oxidation layer pollution of hot-rolled samples. When handling deformed (twisted or bent) samples, it is important to ensure the reliability of test stations and fixtures. The test control software must adopt advanced algorithms to calculate the test results of various strain/stress curves.
3. Tensile test solution of steel plates
Closed loop control; Load ranges from 100 kN to 2,000 kN. The automation system reduces the variability of operator measurement technology and improves the reliability and repeatability of test results. All kinds of clamping devices are provided, including manual, automatic pneumatic/hydraulic wedge clamping devices.
4. Bending test of steel plates
Guide bending test is used to evaluate the plasticity of medium - thickness steel plate
. According to the machine frame used, the bending force of the base is applied to the sample as the platform rises or the beam falls, resulting in bending force. The specimen was subjected to a force exerted by the bending center and formed a 180 degree bend with the supporting roll on the base. The bending diameter required for the test depends on the thickness of the plate. The test machine should have the function of fixed fixture to prevent sliding during the test.
5. Bending test solution of steel plates
Bending fixture to test the plasticity of medium - thickness steel specimens. The clamping device uses the specified diameter of the bending center to align the bending center with the base so that the force is applied to the span center.
