Abstract

Simple cantilever bend testing to assess mechanical descaling of industrial hot-rolled steel rods has been developed and analysed. This test method has no contact damage to the scale, and produces a range of strains along the rod, which always include those for scale behaviour from crack initiation to complete spallation. A series of methods has been used to assess the variation of the plastic strain along the bent rods and the results have been compared with finite element modelling. Using a cyclone scanner for these measurements provides an accurate and efficient testing procedure. To compare with industrial practice, constrained bending around cylinders was also carried out.
