Method and apparatus for aligning equipment in a steel mill
First Claim
1. A method of aligning a guide assembly with the axis of rolling of a mill stand of a steel mill comprising:
- providing a test bench having a corresponding axis and other physical characteristics of the guide mounting bed of said steel mill, providing a pair of pedestals mounted in a predetermined distal relationship on said test bench having predetermined physical characteristics suitable for mounting a guide assembly thereon;
providing a self contained wireless digital camera having a suitable arrangement for mounting on one of said pedestals, providing a target temporarily mounted on said test bench having a target located on said axis;
providing a remotely located video monitor capable of receiving signals from said self contained video camera to display an image generated by said camera;
adjusting said camera and one of said pedestals until said monitor shows an image indicating that said camera is now located on said test bench axis.

Abstract
An alignment device for aligning guiding apparatus with the main axis of a rolling mill comprising a camera and a video display communicating with the camera. The camera is mounted in the steel mill at the position of the guiding apparatus and the camera is moved until it is on the axis of the mill. The camera is then removed to a bench which duplicates the physical characteristics of the mill. The guiding apparatus is mounted on the bench adjacent the camera. The guiding apparatus is physically moved until it is located on the camera axis, which is the mill axis. The guiding apparatus is then remounted in the mill.

3. A test bed for axially aligning equipment along an axis correspondent to the axis found in a steel mill comprising:
-
a bed duplicating the dimensions of guide mounting apparatus of a steel mill;
a pair of pedestals being mounted in a predetermined distal relationship on said bed;
a test target having target means temporarily located on the axis of said test bed;
a camera mounted on one of the pedestals aimed at said test target;
adjustment means on said one of said pedestals to permit adjustment of said one of said pedestals in a horizontal plane to permit said camera to acquire said test target.
