Metallic Tube Edge Rolling Test Method GB 245–82
As technology continues to advance, the need for more and more durable and reliable products becomes more pronounced. In addition, manufacturers must take into consideration the safety and performance of their products and the materials used to construct them. The need for reliable, and safe materials to construct products is just as important as the performance of the product. One of the most common materials used to construct various products is metal. Testing of metal to ensure its reliability and safety is vital, and the Metallic Tube Edge Rolling Test Method GB 245–82 is one such test. This paper will discuss the Metallic Tube Edge Rolling Test Method, including the purpose and procedure of the test.
The purpose of the Metallic Tube Edge Rolling Test Method GB 245–82 is to assess the properties of materials that may be obtained by cold tube edge rolling of sheet, strip, and plate metallic materials. This test method is beneficial for informing the designer of the properties, such as reduced thickness and contact stress, that can be achieved with cold tube edge rolling. Additionally, the test method is used to compare and evaluate the rolling ability on a variety of metals and materials. This test method can provide valuable information when the designer or manufacturer is required to optimize several qualities at the same time or predict how a material will deform when subjected to specific deformations.
The Metallic Tube Edge Rolling Test Method is performed using a Rigid Plate Analysis Guide and a series of tests with varying levels of stress on the sheet, strip, and plate metals being tested. The test method begins with the selection of a test specimen. The test specimen must meet certain criteria in order to be properly tested. The test specimen must be a sheet, strip, or plate of metallic material measuring at least 6 mm (0.25 in.) in thickness and of a size that can fit into the Rigid Plate Analysis Guide. The test specimen should also be free from serious defects.
Once the test specimen has been selected, it is placed into the Rigid Plate Analysis Guide and tightened in place. A steel roller is then used to roll the metal three times. This is followed by a series of tests to determine the contact stress, reduction in thickness, and grain orientation of the test specimen. The grain orientation is used to determine the strength of the material. The tests are conducted at different levels of stress to determine the properties of the metal under varying loads. Following the tests, the specimen is removed from the Rigid Plate Analysis Guide and examined for deformities.
The Metallic Tube Edge Rolling Test Method is a valuable tool for understanding the properties of various metals and materials and how they are affected by various levels of mechanical deformation. It is important to note that this test is not suitable for all materials. Materials that are too brittle or too ductile will not be able to be tested using this method. Additionally, care should be taken when testing materials under stress, as this could cause damage to the specimen or the testing device. Ultimately, the Metallic Tube Edge Rolling Test Method is a valuable tool for determining the properties of metal materials and ensuring their reliability and safety.
