【Abstract】 Through a research on the quenched rails used nowadays, the composition adjustment for off - line whole length quenched rails from Baotou Steel has been finished and the quench process parameters of CPD3, CBNbRE have also been determined . As a result, the synthetic properties of quenched rails are remarkably improved.更多还原
