Monitoring Roller Guide
Technical Information and Features of Quality Steel Production
Growing requirements to the rolled products,
especially with regard to dimension tolerances are requesting a control
of the produced material. This control should be made, if possible, during
the rolling process in order to react without any delay on deviations be
appropriate measurements. A product of inferior or waste quality should
The most effective instrument to take care of such problems
MONITORING ROLLER GUIDE (MRG)
Principle of Operation
The MONITORING ROLLER GUIDE (MRG), developed as an 'intelligent'
roller guide, investigates the forces which work on the arms of the roller
holding device using the patented built-in MRG Sensor
(see picture). If e.g. the incoming section in the roller guide
is changing because of wear in the rolling stands before, the force which
pushes the rollers apart is increasing. This increase is measured by the
MONITORING ROLLER GUIDE, which is connected with a computer
system. All data is recorded by the computer system.
If the rollers of the roller guide are damaged or in case the bearings are
not correct considerable variations of power can be noticed. The computer
generates alerts that the defects have to be corrected.
High Output and High Quality
The MONITORING ROLLER GUIDE, designed to be an integrated
part of the mill, is the ideal device to guarantee a high-output production
with first-class quality. Misalignment, twisting, underfilling and overfilling
of the stock, as well as temperature deviation (cold end) are detected
immediately and indicated on the computer screen so that the operator can
take quick actions to avoid rejects.
In addition, the MONITORING ROLLER GUIDE is able to recognize
any exceeding of given tolerance limits caused by wear on the passes directly
on the place where the exceeding has been developed. Therefore, the MONITORING
ROLLER GUIDE System is designed to monitor different places in the mill
(e.g. roughing, intermediate and finish train).
Moreover, the MONITORING ROLLER GUIDE will also detect
any outbreak on the carbide rolls or any other roll before severe damages
and/or rejects in the mill will happen.
Continous Control of the Rolling Process with
Non-destructive Materials Testing
During hot rolling the MONITORING ROLLER GUIDE continuously monitors the production
process and product quality. It assists you in the early detection of faults like
indentations and roll marks, spills and slivers, shells and seams. The MONITORING
ROLLER GUIDE compiles and presents results for each wire section and each wire coil.
The fault distribution about the length of the roll stock gives you information about
the fault cause (billet or mill).
According to its conception the MONITORING ROLLER GUIDE
shall not be an absolute dimension measuring equipment. It is designed to be the
most efficient device for recognizing critical changes and/or tolerances in
the mill. By comparison with threshold values and by comparing the changings
at different places in the mill it is possible to continuously control the
rolling process with very little effort.
