What is the testing procedure of mill scale?

The testing procedure for mill scale typically involves several steps to assess its physical and chemical properties. First, a sample is collected and weighed, followed by a visual inspection to identify any contaminants. Next, chemical analysis is conducted, often using techniques like X-ray fluorescence (XRF) or chemical titration to determine the composition of iron oxides and other elements. Finally, physical tests may include measuring particle size distribution and assessing magnetic properties, depending on the intended application.
