SORM 3plus roughness measurement on molybdenum

Sometimes the demands on quality assurance systems, in this case the SORM 3plus online roughness measurement system, are as if they were from another world. Or have you ever thought about conducting roughness measurements on sheet metal made of molybdenum alloys?

To refresh your memory, molybdenum is a paramagnetic transition metal with the atomic number 42 and, in small additions, it is used to harden and prevent the embrittlement of steel. More than two-thirds of the molybdenum produced is used to create metal alloys such as ferro molybdenum. Today, molybdenum is used as an alloying element for enhancing strength, corrosion and heat resistance properties, and is therefore a material that is preferred by the aerospace industry.
This is precisely the reason why a Chinese manufacturer of molybdenum sheet metal (panels) sent a request to EMG to measure the roughness of the material online with the SORM 3plus system. Nothing could be simpler than that?

Not quite because, first of all, SORM 3plus is not designed for measuring single sheet panels and, what's more, these panels also need to be checked from both sides.

The solution successfully implemented by EMG consists of an elaborate design, which ensures the sheet panels are initially fed to the SORM measuring head in a dynamic manner. After measuring the roughness on the top of the panels, they are rotated, then fed into the system again and the roughness is measured on the rear side. This special design was developed, tested and implemented in cooperation with EMG China and the end user. The system has since become accepted and successfully used in the production sector.
