Flexible deburring grinding solutions for slabs, blooms and billets for continuous production
BRAUN has developed a cast product deburring grinding solution, based on its well-proven HP (high-pressure/high-performance) grinding machines. The machines are able to rapidly and reliably remove burrs from both ends of the cast products and at both the lower and upper edges or, if necessary, to grind the cut end […]
Oil resistant Cr-free passivation coating for hot dip galvanised steel
One of the approaches to replace Cr-based passivation coatings with non-Cr is to use formulations based on sol-gel chemistry to provide a dense protection film on the metal substrate. However, as anti-rust oil is often applied on top of the passivation coating this usually deteriorates the corrosion protection performance of […]
Process and technologies to anneal current and future advanced high strength steel strip
The production of advanced high strength steel (AHSS) grades in a continuous annealing line requires strict cooling control to limit strength variation within the coil to improve homogeneity and formability. Fives has developed a new cooling technology, Wet Flash Cooling®, to reach the required AHSS characteristics.
CaliView® mobile measuring system for pipe and tube mills
SMS Group has developed a mobile measuring system, CaliView®, for checking the contour, position and alignment of passes in tube rolling mills without the need for elaborate manual measurements. Deviations detected by the system can be corrected easily and quickly before they manifest themselves in rolled product.
Cross Light Illumination for surface inspection
Surface inspection has been greatly enhanced with the latest developments in LED technology utilised in stroboscopic inspection. The ability to precisely control the flash duration time of LEDs now enables inspectors to have sharper and crisper images of the strip surface, allowing them to detect finer anomalies. This control over […]
Optical measuring systems for plate mills
Advances in camera technology have enabled a significant enhancement of dimensional measurements in plate mills. Slabs and as-rolled and cut-to-size plates can now be measured with a very high spatial resolution while providing more detailed and pinpoint evaluations of the measured data. This has become possible primarily due to the […]
Methodology to quantify objectively Zn coating weight uniformity
Zinc coating weight on steel strip is affected by many process parameters, leading to non-uniform coatings. This can lead to surface quality issues and increased costs when thicker coatings are applied to ensure the minimum coating weight meets specification. A standard easy-to-run methodology is proposed to compute, not only the […]
Turning knowledge into action for consistent strip quality and increased production efficiency
CMI, one of the leading suppliers of equipment for the processing of steel, has launched its latest, innovative servicing offer, OPExS™, providing technical assistance based on process and operation expertise combined with easy-to-use software. This combination is designed to help customers bridge the knowing-doing gap (turning knowledge into action) when […]
EMG SOLID®: On-line oil layer measurement with infrared and laser-induced fluorescence spectroscopy
Manual oil layer thickness determination is definitely no longer sufficient for the sensitive and highly developed manufacturing processes used today. EMG offers two technological solutions under the product names EMG SOLID®IR (infrared spectroscopy) and EMG SOLID® LIF (laserinduced fluorescence spectroscopy). Other than the core sensor technology both system types are […]
