During the SEAISI Conference 2015 the latest design and process features of the new 3-roll RSB® generation was presented together with the unique Size Control System SCS® for a real time closed loop control to produce an extraordinary quality SBQ – day in, day out. In reality, the performance of any size control system is dependent on the performance of the respective gauging system. Any deficiency of such a measuring unit has a very negative impact on the resulting product quality. Gauges used in the past generally operated with the “shadow” measuring system. The latest gauge developments are based on the “light section” method. This method is more suitable to provide real time measurement parameters of the rolled bar. Placed close to the last rolling stand, the “light section” gauge is capable of measuring around the complete diameter circle with a clear definition of the bar stage in relation to the axes of the rolls. It is also capable of making these measurements using a very high measurement frequency. Following the latest tendencies in the marketplace, which require highest gauge measuring frequencies in order to display the bar in the most accurate way, even at the highest rolling speeds, the “4D Eagle” gauge was developed. The “4D Eagle” gauge operates with light sectioning by laser triangulation with the highest available measuring frequency and without mechanical movement of the sensors. This paper describes all the process features and parameters of this impressive and unique newly developed gauge.
