| Abstract: | The breaking load of the mining high strength ring chain is very important, which is related to the normal operation of the scraper conveyor and the production safety of the mine. Aanalyzed the fracture shape, fracture position, breaking load and breaking elongation of mining ring chain in tensile test. The causes of chain fracture that does not meet the requirements of tensile test were analyzed and improved. |
