The survey of the housing includes the 3D measurement of the complete mill stand window without liners. As result we get the actual geometry in reference to the rolling direction, the virtual middle axis and the overall window geometry itself.
Laser Tracker Supported Measurements
Based on our 3D-survey and analysis it is possible to precisely analyze the given state of the mill window and possible deviations which can easily lead to a permanent pre-set for cross rolling and all related quality issues with the final product.
The perpendicularity of the mill stand
The opening of the mill stands window with or without liners
The parallelism of the mounting surfaces/liners
The perpendicularity of the base plates to the centerline of the mill window
The symmetry and parallelism of all liners
The geometrically relation between all stands
The inspection of the liner fixations
he perpendicularity of the mill stand to the roller table/floor
