Mill Window Profile Analysis

Comprehensive Analysis

At AIM, we believe we provide the most comprehensive Mill Window Survey and Analysis in the industry. Our unique methods and tooling allow us completely and accurately map your mill window; including the vertical profile of each liner surface, mill window skew to the process centerline and the bottom liner pockets.  We also have the ability to perform a complete roll chock analysis to determine roll crossing and chock condition.

Using the window opening and skew at passline as reference, the liner positions are mapped from the bottom of the mill to the top of the mill. The results are compared to the plan to indicate possible wear or misalignment of the liners and window opening.

More Than Just Data

AIM customers receive much more than just survey dimensions and measurement data. Our reports include graphs, drawings and layouts as well as interpretations, analysis and specific recommendations. An AIM Mill Window Profile Analysis provides customers the information they need to make objective, data-based decisions to improve their rolling process.

Mill window skew is rarely considered or measured. However, the relationship of the mill window to centerline is critical, especially in multi-stand mills or reversing mills. Examples include: hot mill roughing (edge rolls) and finishing stands, tandem and reversing cold mills, as well as temper mills. Shape defects and mill control problems can develop if the mill skew is out of tolerance.

Position Monitoring System - Paper Log Eccentricity

Paper Log Eccentricity Application

American Industrial Metrology offers precision non-contact position monitoring solutions. The systems measure linear position of machine components or product surfaces without the error created by mechanical clearances and backlash. The systems utilize high-precision triangulation Laser Displacement Sensors. The high-speed sensors measure the distance to a surface target. This distance is used to calculate the position of the diameter of a roll or log. The live displacement data is transmitted via a wired connection to the Display Unit processor. The data is processed to calculate machine position or other configurable position measurements.
 

AIM’s Paper Log Eccentricity System measures the outside diameter of a log of paper using two precision laser displacement sensors. By monitoring the precise position of the outer surface of the log as it unwinds on each end of the log, the relative eccentricity or diametric difference can be accurately calculated. The live displacement data is output to a digital or analog signal which can be connected to the customers control system. The display unit is housed inside an aluminum case or can be custom mounted in most operator panels. This system provides safe, real-time monitoring of the process with the ability to store and trend the data.

The position monitoring solution can be applied to a wide variety of applications. Contact AIM today to put our creativity and experience to work for you.
