| Abstract: | In the paper,the microstructure,causes and position of white layer are analyzed by taking the C900 A rails as an example and combining with the relative data in the experiment of developing heat treated rails with the European standard after reform the production line of electro hardening in Rail and Beam Plant of Baotou Steel. Moreover,the factors influencing causes for white layer are briefly elaborated and the control measures are proposed. |
