文摘A kind of heat treatment technology of thermit welds was introduced in this paper. Through the heal treatment not only the mechanical properties are improved, but the hardness of head was redistributed. Heat treatreatment alleviated the soften of the quenched rail clue to welding. The technology has been successfully applied to lay the lines and crosses at Da-qin continuous line.
