| Abstract: | The reason of rack rail quenching and tempering cracking is analyzed . According to the ear structure of rack rail the plug hole is designed and its test is also verified that hardness and surface could meet the technology demand. Such thought and preventing cracking method could be popularized in alternated timed quenching by water and air for other carbon steel. |
