When repair steel poles, usually required for large lathes Flashlight overall processing, but manufacturers are not generally large lathes, therefore, makes it difficult to repair work. After years of practice, summed up the method to repair damaged steel flange, through actual use to good effect, repairing steps are as follows:

     1, completed a full circle blanks, determine the size of the hole in the flange and coupling bolt hole center position.

     2, gas cutting the hole to the required size and cut out the welding groove, with a grinding wheel slag spines, scales and so on.

     3, within the center of the hole as a benchmark, vehicle processing cylindrical mouth ended and the end, and then drilling.

     4, half the level of the entire steel sheet placed in the bracket (or centrifuge) on the flange cut in half, with another section of the flange connecting bolts and tighten the flange in contact with the cylinder and make the best location.

    5, to prevent deformation of the flange during welding, spot welding along the inner barrel flange connections.

    6, the two steel together, tighten the bolts and connecting flange bolts hekou, even symmetric outer continuous welding.

    7, the steel open inner welding.

    8, Tisha hand grinding and polishing connection flange spigot cross section.

    9, the operation of the centrifuge test machine.
