— Millmate roll force systems Introduction A measurement technology offering high accuracy is a prerequisite for modern rolling mills of today. — 01 System overview ABB’s Millmate rollforce system in rolling mills The constant striving to achieve optimum process quality and the highest possible productivity is the essential goal of modern production units. Rolled products are called upon to meet ever stricter demands, and as a consequence so is also rolling mill equipment. A truly measured roll force is crucial in achieving correct roll gap settings, true force distribution from operator side...

MILLMATE ROLL FORCE SYSTEMS RELIABLE, LONG-TERM SOLUTIONS Pressductor® Technology Measurement principle ABB’s Millmate roll force load cells are based on the well-known Pressductor® principle patented in 1954, utilizing the magneto-elastic effect, according to which the magnetic properties of steel are influenced by mechanical forces acting on it. 01 700% of nominal load. The highest permissible single loading without mechanical damage to the load cell 300% of nominal load. The highest permissible load without permanent change of data 02 Load cell application in hot rolling mill 03 The measurement principle...

— Load cells The heavy-duty Millmate roll force load cells have high stability components protected by a stainless steel box providing the built-in calibration and temperature compensation of the load cell. — 01 4-high mill stand — 02–04 Load cells can be installed in several different ways, but the preferred arrangement, from both the economical and technical points of view, is usually to install the load cell under the mill screw. Due to its low impedance and high output signal power the Millmate roll force load cell has an extremely low sensitivity to insulation defects and maintains its measuring...

Rectangular load cells PFVL 141V for mounting under the lower back-up roll bearing housing There must be a sufficiently large flat surface on the lower part of the roll stand to allow the installation of the load cell under the lower back-up roll bearing. This arrangement has the advantage that there is no need to pay particular attention to the load cell during roll change. See also our offer regarding Load Cell Packages on the next page. The load cell can be adapted to the required dimensions, and the length is chosen as a multiple of 30 mm. For load cells longer than 900 mm, the chosen length...

— Load cells Installation arrangements — 01 ABB offers a complete range of roll force load cells of different types and sizes. Connector cables to be preferred to fixed cables. — 02 Step-by-step assembly of our prestressed Load Cell Package Load cell packages When the load cell is positioned under the lower back-up roll bearing, which is the most exposed position, we can offer a pre-stressed package with lower pressure plate, load cell, frame and upper pressure plate. The safe and compact Load Cell Package secures easy and correct installation. You increase the possibility of accurate measure,...
