Mold Expert

The world’s leading mold-monitoring system, which allows plant operators to look further down the strand and gain deeper insights into the factors that influence solidification in the mold and the process itself. Find out more

OsciMon and OsciChecker Wireless

Tools for analyzing different types of oscillator behavior of continuous casting machines and optimizing the required maintenance time. They measure oscillator movements in all three directions, and store and visualize measurement data in 3D. Find out more about OsciMon and OsciChecker Wireless

Additional measuring system for control and adjustments

Individual devices for several different mold formats and measurements can be applied in any conventional caster and adapted to specific customer needs. These robust measuring systems help operators to measure the distance between opposing rolls, the gap, alignment, rotability of rolls, and also analyze oscillator behavior.

Advanced rolling and processing technologies

Primetals Technologies makes sure that steel plants always have the latest technologies in place, helping producers to constantly raise quality standards and to meet growing market demand.


EdgeMon is applicable for technologies such as Pickling Line (PL) and Coupled Pickling Line and Tandem Cold-Mill (PLTCM). This system enables the simultaneous inspection of the trimming process at both sides of the strip at full plant speed. Magnified images are visualized, knife breakouts are detected automatically, and warnings are issued in the event that edge quality falls short of the required quality standard. Cut-break ratio and burr are also measured. Find out more


PropertyMon is suitable for metallic coating lines such as Continuous Galvanizing Line (CGL), and it is a quality monitoring system for the online detection of mechanical or magnetic properties of the steel strip. The system performs a continuous, inline, and contactless inspection over the whole strip length based on an electromagnetic measurement principle. The results are immediately available, visualized for the benefit of the operator, and stored in PropertyMon’s internal database. Find out more  


ShapeMon is compatible with hot rolling flat technologies such as plate mill. It is an optical sensor based on the self-radiation principle. ShapeMon is safely installed above the roller table at a height where it interferes with neither the rolling process nor the movement of the crane. When passing the field of view, the sensor automatically detects the plate and initiates the measuring procedure. Find out more


TorqueMon is suitable for cold rolling and hot rolling mill stands. It is a reliable system for measuring the torque of rolling-mill shafts.Permanent, real-time measurement is based on the principle of strain gauge measurement, and sensors mounted on the rotating parts which send the measurement signals to a rotary antenna. Find out more

Greater transparency in steel production

Primetals Technologies offers an innovative condition-monitoring system for the metals industry that integrates information from multiple sources in order to accurately describe the condition of functions, equipment, and even entire plants.

Predictive maintenance with advanced condition monitoring

ChatterBlock Monitoring detects dangerous third-octave-mode chatter in cold rolling mill  stands before it becomes audible. Line speed is then automatically reduced and the rolling mill returns to safe operation. Furthermore, the ChatterBlock Monitoring algorithms can detect fifth-octave-mode chatter and roll defects (e.g. eccentricities, flat spots) of work and backup rolls. Find out more

Reference Story: Condition-Monitoring System based on Shock-Pulse Technology

Tata Steel Limited, Jamshedpur

Type of plant
Continuous caster ladle turret

Our solution
The use of shock-pulse technology in predictive or condition-based maintenance allows even very slow rotating bearings, such as the large swivel bearings of ladle turrets, to be monitored by measuring the small shock waves that result from metal-to-metal contact and that resonate through the bearing. The system is easy to install, and monitoring can be carried out on or offline. Signal analysis allows any potential bearing problems to be diagnosed before the situation becomes critical, thereby preventing outages or even shutdowns of the ladle turret. This solution is designed to maximize bearing lifetime, to allow sufficient preparation time should a bearing need to be replaced, and to minimize the risk of unplanned shutdowns.
