Installations with rectangular load cells below the lower back up roll or above the upper back up roll:

Accessible parts: Mounting surfaces in the mill stand, the sledges if present, the rockers,

the pressure plates closest to the load cells and

intermediate mating plates if present.

Installations with circular load cells under the screw-down or hydraulic cylinder:

Accessible parts: Mounting surfaces above the upper back up roll

bearing chuck, plain or tapered thrust roller bearings, pressure plates

closest to the load cells and other intermediate mating plates if present.

Installations with annular load cells above the screw-down inside the mill stand:

Accessible parts: Mounting surfaces of the screw-down nut, plain or

tapered thrust roller bearings, pressure plates closest to the load cells.

The parts and mounting surfaces mentioned above need to be accessible

before the start of the work or otherwise the investigation of

them need to be planned for in advance so that it can be performed

later during the site visit.

Service duration

Typically 1 day on-site to inspect the roll force measurement installation, evaluate and give

recommendations if further actions are needed.

During at least 4 hours, load cells and pressure plates need to be accessible outside the mill stand

for inspection and testing. This can be done during a planned maintenance stop, or by the customer

exchanging to spare load cells and spare pressure plates in the mill stand in advance.

Additional time for travel, preparation, analysis and reporting is needed.

Note: Free access to the mechanical parts and the mounting surfaces 

in the actual mechanical installation is essential for achieving

the expected goals with the Health Check during the site visit. The

accessible parts required for different load cell types and positions

in the mill stand are listed below.

The parts and mounting surfaces mentioned above need to be accessible

before the start of the work or otherwise the investigation of

them need to be planned for in advance so that it can be performed

later during the site visit.

Get the competitive edge through the Millmate Roll Force System health check.

Measurement made easy.

Overview

Millmate Roll Force System Health check is a detailed and comprehensive inspection and

status evaluation of a roll force measurement installation.

It is a key service to ensure and verify the actual roll force measurement accuracy to avoid future

interruptions in the production. All findings are documented in a roll force system health check

report and the recommendations can be used to secure measurement accuracy and availability,

mill performance and yield.

Remarks

– The analyzer performance characteristics have been

determined according to IEC 61207-1:2010 “Expression of

performance of gas analyzers– Part 1: General”. They are

based on nitrogen as the associated gas. Compliance with

these characteristics when measuring other gas mixtures

can only be assured if their composition is known.

– All specifications refer to an optical path length (OPL) of

1 meter, tested in ABB’s test and calibration jig. However,

application-dependent variations may occur. The specific

detection limit, minimum and maximum measurement range

for a specific application will depend on the gas conditions

(pressure, temperature and gas composition) and optical

path length. Minimum measurement range, maximum

pressure and maximum temperature cannot necessarily be

realized simultaneously under all conditions.

– The maximum pressure and maximum temperature given

are physical (spectroscopic) limits.

– Applications exceeding the above given spectroscopic

limitation might be possible on request.
