| Abstract: | This paper deals with the structural transformation law of 25SiMnMov steel at variant austenizing-temperature, heating and cooling rate, and analyses the welding joint structure of annular chains of grade D for mining. The work can supply the welding and heat-treating production of annular mining. chains with the theoretical proofs of structure transformation. |
