Research on Online Texture Measurements in Metal Rolling Field
2012, 17 (6):
In rolled strip material, the orientation of the crystallites, known as texture, is influenced by various
kinds of thermo-mechanical processes, such as casting, plastic deformation, annealing and phase transformation.
The modern industry production requires stable product performance, real-time monitoring and full controlling of
the quality. The online texture measurement in metal rolling can be used to real-time monitor the whole process,
and then feedback control to the production process can be implied to adjust the process parameters to ensure
the stability of the products. The principles, advantages and disadvantages of related detection methods (2D Xray
diffraction, neutron diffraction, laser-ultrasonics and electromagnetic acoustic transducers (EMAT)) and the
possibility of online measurement are discussed. Finally, 2D X-ray diffraction and laser-ultrasonics are employed
on online texture measurement, and the schemes of online texture measurement are proposed.
