Abstract
In an apparatus for changing the rolling mill rolls and/or disk shoes of a steel pipe rolling mill, the top and bottom rolls vertically movably mounted in the housing are individually placed on a supporting bed positioned below the bottom rolling roll and moved in and out of the mill by way of rails laid in the lower part of the housing, and each of the disk shoes is mounted on a supporting arm which is movable vertically and rotatable thereby making it possible to change the disk shoes even during the operation.
